Welcome letter
Henrique Cabral
Coastal systems are subjected to intense human pressures
worldwide. Effects of these anthropogenic impacts have been
reported from genes to ecosystems, and extensive knowledge
on these issues has been gained in the last few decades.
Nonetheless, the accumulated science and expertise have not
always been used to improve management of coastal
ecosystems.

Estuarine and Coastal Sciences Association (ECSA) has a
long tradition of contributions in this field, in particular by
organizing workshops and conferences worldwide. A large
number of ECSA conferences have introduced and highlighted
management issues. The 2014 edition of the ECSA
Conference, ECSA54, will address global changes in coastal
systems, with emphasis on the development of predictive and
assessment tools to evaluate these changes, especially
disentangling anthropogenic effects from natural variability.
On behalf of the organizing committee and the Centro de
Oceanografia of the Faculdade de Ciências da Universidade
de Lisboa I would like to welcome you all to the ECSA54, in
Sesimbra, a typical Portuguese coastal town with a strong
liaison to the sea and where fisheries and tourism are major
economic activities. I hope that this Conference will promote
discussion, exchange of experiences and collaboration among
the scientific community and thus contribute to strengthen our
knowledge on coastal ecosystems and to develop new and
refined tools for management.
Finally, I would like to thank all the institutions that supported
ECSA54, especially the Câmara Municipal de Sesimbra for all
the facilities provided, all members of the scientific committee
for their commitment and encouragement and to the ECSA54
Secretariat members for their hard work in the past two years,
for being a truly supporting team and for their friendship.

Morphosedimentary changes in intertidal estuarine environments at different timescales
Freitas MC, Andrade C, Silva T
Departamento de Geologia, Faculdade de Ciências da Universidade de Lisboa, Campo Grande, 1749-016 Lisboa, Portugal
[email protected]
Tide dominated low-energy estuarine morphosedimentary units in general develop from subtidal to intertidal
flats, the latter eventually evolving into marshes which accrete until reaching a critical boundary. The rate of
intra and inter units evolution depends on tidal regime, sediment supply and sea-level change and are
described by well known conceptual models. The Tagus estuary offers a spatial mosaic of such features
developing under distinct constrains and the vertical succession of sedimentary facies allows knowing their
evolution over the last millennia. Departing from four sediment cores, the time-sequence of sediment
accumulation has been reconstructed and the long-term and short-term accumulation rates determined. These
are further explored to extrapolate accretion of estuarine margins into the end of the century and under
different forcing associated to enhanced sea level rise. Besides the vertical response, the intertidal units may
expand or retreat in area. In the study area examples of these two behaviours were found and results from
aerial imagery and field experiments are presented.

A methodology for the establishment of biotopes at the estuarine scale in the southern North-East
Atlantic region
Galván C, Puente A, Juanes JA

Corresponding author: [email protected] (C Galván)
A biotope is defined as the combination of those physical and chemical properties of the environment that
determine the spatial patterns of estuarine species. From this point of view, a hierarchical classification system
to identify and characterize biotopes was developed in order to get a predictive model of the potential biota
distribution. Such classification system was based on information about eight abiotic variables (sediment
consolidation, depth, salinity, emerged time, water column height, current velocity, sediment composition and
water renovation) with specific thresholds that determine the most relevant ecological differences. All these
variables were characterized through a combination of field data, numerical modeling and statistical
techniques. The classification system allowed defining biotopes at different spatial scales. It is important to
note that a more detailed description level entailed an increase in its complexity. The methodological approach
was applied to an estuary located in northern Spain. As a result, a detailed description and distribution of the
most representative biotopes of the estuary were obtained and validated with biological data.
Macroinvertebrates and saltmarsh vegetation distribution were coupled to biotopes, hence the model was
capable of predicting their spatial patterns.

A better understanding about what drives coastal erosion and accretion patterns is vital to predict future
developments in a changing environment. We studied the Douro estuarine sand spit (N-Portugal), which is
protected by a detached breakwater. Since breakwater construction, seven years ago, spit area and volume
increased steadily westwards, and seasonal patterns became evident, with erosion and accretion oscillating
between the northern and southern part of the W-face. Digital elevation models derived from half-yearly
topographic surveys were used to quantify coastline migration and changes in beach area and volume. Local
patterns were subsequently related to river flow, wave and wind conditions through correlation and regression
analysis. Erosion at the inland E-face was significantly related to strong winds, and in its northern part also to
high river flows. Erosion at the NW spit tip was related to high ocean waves. The seasonal coastline oscillation
of the W-face depended mainly on the predominant wind and storm directions. Beach line dynamics and
erosion and accretion patterns were quantified depending on beach exposure and seasonal conditions, which
21
allows inferences about beach development, considering future climate changes affecting river flow, wave and
wind conditions, and changes in wave and wind directions.

Overwash may seem catastrophic; however, from a longer term perspective it is a nearly continuous process,
during which the net volume of sand is often maintained, but the environments translate shoreward. Overwash
processes are major driving mechanisms of sandy and gravel barriers. However, these barriers have
contrasting features such as sediment properties, barrier morphology, and infiltration rate. To study the
differences in gravel and sandy barriers response to overwash, two laboratory experiments (BARDEX 2008
and BARDEX II) were conducted in the Delta flume (The Netherlands), at prototype scale. The morphological
response was studied by manipulating waves and water-levels. One of the main differences was the
(in)existence of an early stage, overtopping, that occurs when the water intrusion across the barrier is small,
promoting a rise of the barrier crest. At early stages, gravel barriers exhibit overtopping, whilst sandy barriers
do not. Once overwash regime starts, with larger overwash water discharges, then both barriers exhibit
significant crest lowering and backbarrier deposition. Surprisingly, the threshold for the start of overwash was
similar in both cases. These experiments are unique and contribute to the knowledge of storm impacts, provide
valuable data to improve modelling of coastal hazards and practical guidance for coastal management.

Post-industrial expansion in Lagos, Nigeria has caused many changes to the city of Lagos and its environment.
The population of Lagos increased from 1 million in 1963 to around 10 million as at 2006. This has caused
extensive damage to the natural ecosystem of the Lagos Lagoon and its water quality together with significant
coastline and morphology changes around the entire Lagoon coastline and catchment areas. This paper
presents the changes to the coastline and Lagoon morphology and the consequential damage to the Lagoon’s
natural environment by the industrial expansion. By comparing existing charts with a modern coastline, there is
evidence of change to the Lagoon’s coastline with erosion and inundation. The settling of sediments within the
Lagoon makes it a repository of pollution (as observed in 2014 field observations), albeit some pollution will
have dispersed to sea. Significant changes to the morphology are observed where the river and industrial
channels are located, due to the large volumes of polluted water originating with anthropic influence within the
natural catchment area. Future restoration of the coastline is highly dependent on an efficient management of
the Lagoon and its environment.

Tidal dynamics in a changing lagoon: flooding or not flooding the marginal regions
Lopes CL, Dias JM
NMEC, CESAM, Physics Department, University of Aveiro, Portugal
Corresponding author: [email protected] (CL Lopes)
Tidal propagation in estuarine systems is determined by estuarine geomorphology and by the local mean sea
level. Tidal amplitude was amplified in Ria de Aveiro along the last decades due to channels deepening.
Consequently, flooding of marginal regions is presently occurring frequently and flooding of higher areas is
anticipated in response to sea level rise. This study aims to assess local tidal changes admitting the flooding
protection and no protection of lagoon margins. To achieve this goal, the hydrodynamic model ELCIRC was
applied and validated, and tidal properties and residual currents were assessed under different scenarios
defined for past and future lagoon configurations and considering the flooding or not flooding of the marginal
regions. The validation was successfully achieved, with highest accuracy found at the central area stations.
The results highlight the sensitivity of tidal properties to bathymetric modifications, with important changes in
tidal amplitude and distortion. Also, the tidal currents increased over the past and a trend to further increase
22
under MSLR was found. The residual currents are seaward at the inlet highlighting the exportation of materials
to the ocean, which tends to increase under SLR conditions. Important differences were found between
flooding and no flooding runs.

The study and modelling of river plumes is a key factor for a complete understanding of the associated
dynamic and coastal processes, including sedimentary transport. This study is focused on the implementation
of a forecasting system for the Douro river plume as part of the RAIA.co project objectives. Satellite imagery
was analysed showing that the river Douro is one of the main sources of suspended particles, dissolved
material and chlorophyll in the NW Iberian Shelf. Several simulations were performed: schematic winds;
extreme case. The ROMS model was selected because it is being used in the scope of the RAIA and RAIA.co
forecasting. The schematic wind case-studies suggest that the Douro river plume is wind-driven with wind
enhancing the vertical mixing. Differences appear in its structure and dispersion depending on the wind
strength and direction. Southerly winds push the river water finding Douro water in the Galician Rias, and
upwelling favourable winds induce plumes with a narrow coastal current. Extreme river discharges, associated
with southerly winds, can transport debris to the Galician coast in about 60 h. This can help to explain extreme
events, including those that occurred in 2001 by the time of the Entre-os-Rios bridge accident (March 2001).

Located at the northwest corner of the Iberian Peninsula, Ria de Vigo is a partially mixed estuary, the
southernmost of the set of estuaries know as Rias Baixas. Due to the influence of the upwelling Ria de Vigo is
very productive with a strong economic sector involved in mussel growth as well as other fishery production.
On the other and the Ria de Vigo estuary is under the influence of a medium sized city (300 thousand

Thermohaline trends along the water column were analyzed by means of Argo float data along the Atlantic Arc
extending from 27.5°N to 48°N over the decade 2004-2013. With this aim, three water masses were
considered: Surface Water (SW, 0-100m), Eastern North Atlantic Central Water (ENACW, 100-600m) and
Mediterranean Water (MW, 600-1200m). Moreover, three different regions were analyzed separately: Bay of
Biscay (43.5°N-48°N), Western Iberian Peninsula (36°N-43.5°N) and the Northwestern of Africa (27.5°N-36°N).
Although some differences were found depending on the region, in general, SW was observed to salinificate,
while not significant trend was found for temperature along the whole Arc. ENACW was found to warm and
salinificate. This warming showed a north-south gradient, reaching the highest positive trend in the
Northwestern Africa region. In contrast, MW cooling and freshening was observed, with the exception of the
southernmost region where not significant trends were found. Temperature and salinity variability were mainly
due to intrinsic changes in water masses. Vertical displacements also played an important role in ENACW for
the whole area, although the contribution of these vertical displacements varied significantly from the Bay of
Biscay to the rest of the Atlantic Arc. Vertical displacements were negligible for MW.

The Albufeira lagoon, located 25 km south of Lisbon, is separated from the ocean by a 1.5km N-S sand barrier
that is annually mechanically breached to avoid eutrophication. The artificially generated tidal-inlet evolves
naturally until closure, essentially forced by waves, the channel migrating in agreement with the prevailing
southward net littoral drift. Until 1996 migration occurred along circa 1 km of the barrier, but later it became
restricted to a narrower extension, following construction of a 550 m-long, 8 m high artificial dune (AD) aiming
to prevent overwash and limit inlet drifting. Morphological analysis (aerial photos, DGPS field surveys) shows a
non linear 68% reduction of the original AD length until 2014, at the expense of its southern tip, mainly
promoted by tidal inlet drifting and relocation. In the very first year the AD lost 69 m; 106 m were eroded
between 1998 and 2010 (80 m of which after 2002) indicating a steady loss of 8-10 m/year. In the recent past
(2010-2014) erosion rate peaked to 50 m/year, corresponding to a loss of 199 m in only 4 years. Rather than
representing a trend, these figures are a consequence of the atypical wave conditions observed from 2010
onwards that increased the annual intensity and frequency of northward drift currents.

The present study aims to identify morphological changes and sediment fluxes in a tropical coastal lagoon,
Segara Anakan, Indonesia. Its high sediment input related to high hinterland erosion because of land use
change is considered a major problem by stakeholders. A Delft3D morphodynamic model was set up in the
domain (Deltares, 2011) and was driven by river discharges and tides. The model was calibrated using field
measurements collected during the multidisciplinary German-Indonesian SPICE (Science for the Protection of
Indonesian Coastal Marine Ecosystems) research programme in the years 2005, 2006 and 2013. Scenarios
were created in order to investigate the influence of the river discharge and tides on the water and sediment
fluxes at the channel outlets and the sediment budget of the lagoon. The exchange mechanism is strongly
controlled by river discharge at the western outlet, while tidal forcing is the major control at the eastern outlet.
Additionally, we find that 12% of the total sediment input is deposited in the lagoon while the rest is exported to
the Indian Ocean. The western part of the lagoon shows a high dynamic of depth changes due to its position
which close to the sediment input. This results in a high rate of sedimentation in the central part of the western
lagoon and a low rate of sedimentation in the eastern part of the lagoon. The general patterns of erosion and
sedimentation of model results are in good agreement with the observed morphological features and hydroand sediment dynamics. Creating scenarios of future developments in terms of morphodynamics and habitats
will provide useful information for the management of the lagoon.

Seafloor topography influences the sea circulation and mixing that moderate biological diversity and food
resources. Scientists and researchers are extending their understanding to regions deeper than 30 m in order
to protect and monitor ecosystems. To locate and study resources associated with particular terrains, it is
necessary to map benthic terrain. New data collection and mapping techniques are required to extend the
shallow water classifications for potential habitats in deeper water. In this study, a new 30-arc second
resolution global bathymetry grid (SRTM30_PLUS) developed from a wide variety of data sources has been
used in mapping benthic zone. Layers of bathymetry, slope, bathymetric position index, and rugosity were
produced and combined in a Geographic Information System and assessed with unique algorithms that had
been used widely in benthic terrain model studies to produce seafloor classification maps so that sharing
24
results and data become easier. The contribution of this paper is that it presents such a scheme for Western
African Water, Iberian Sea and Celtic-Biscay seafloors, at depths of -1 to -5162 m. These may lead to more
efficient management, advancements in marine and coastal research and improvements in geo-referenced
marine mapping.

The Bay of Cádiz (SW Spain) is a semidiurnal low-inflow estuary that harbors port facilities. Its morphology is
characterized by a seaward outer bay, an inner bay with extensive tidal marshes, and a channel connecting
both. Human activities, which frequently encounter with water quality and ecosystem preservation, have
profoundly changed the bay’s natural configuration during the last decades. Also, projected interventions (i.e.
new port terminal and channel deepening) imply future challenges for the assessment of their impacts on
morphodynamics. To assess them, a field survey consisting of 13 instruments was carried out from 2011 to
2012. Measurements revealed that the estuary is short tidally-driven, and elevations and currents are in
quadrature. At subtidal scale, the inner (hypersaline) and outer (thermal) parts operate almost independently.
Based on these results, a hydrodynamic model (DELFT3D) was calibrated and validated, obtaining good
correlations between modeled and observed (intra and sub-tidal) data. The results indicate that dredging works
would enhance residual currents, increasing both erosion and deposition rates along the channel. The
divergence of the residual velocity field indicates that erosion is expected to occur on the banks and at the
boundaries of the new terminal, whereas deposition mainly affects near channel areas.

The coastal area of Samborombón Bay ends in a short cliff which, during the last decades, has been
undergoing an increased retrogression of approximately 8.2 m per decade. The aim of this work is to
investigate whether this accelerated erosion can be related to an apparent wind-wave climate change, which
has been recently reported for the Río de la Plata region. A numerical study with SWAN wave model for the
period 1971-2005 drives to positive trends in the frequency of occurrence and heights of waves propagating
from the E and ESE. Particularly, the number of cases of high waves from those directions displays a
significant increment. In addition, previous papers have reported an increment of the frequency, height and
duration of the storm surges in the Río de la Plata, as well as a rise of the mean sea level in the region. It is
concluded that the combination of those three factors acting together constitutes a powerful and effective
mechanism which is likely responsible for the observed increasing erosion in Samborombón Bay.

Tidal boundary layers are important for phenomena such as transport of pollutants and biological material (e.g.
fish larvae and plankton), sediment transport and vertical mixing. A turbulence closure is necessary to obtain a
good agreement with measurements. In a parallel work the effect of residual currents on the tidal flow beneath
surface wind is investigated by comparing numerical results with field measurements. A tidal drift results from
the residual current and the surface wind stress; there is an interaction between these two mechanisms. This
work gives a systematic investigation of the tidal drift in combined tidal and wind driven flows with residual
currents. The interaction between the wind, residual current, tidal forcing, bottom roughness, and the Earth's
rotation will be demonstrated. It appears that residual currents have a large impact on the direction of the mean
25
depth averaged velocity and the mean bedload sediment transport, while the direction of the mean surface
velocity is less affected. Further details will be presented at the conference.

Modelling the Zambezi River plume, implications for coastal fisheries and management

Corresponding author: [email protected] (CJC Reason)
The Zambezi River represents an important source of freshwater to the Sofala Bank in the western
Mozambique Channel. Outflow from the river influences the secondary production of coastal waters.
Observational data are analyzed together with ROMS model experiments to describe the main features of the
Zambezi River plume, and its response to ambient factors. In the absence of wind, tides, and ambient current,
a sizable unsteady plume forms under a constant-slope bathymetry and straight shoreline. A bulge is formed
that grows continually as it re-circulates anti-cyclonically in front of the mouth, together with a coastal current
that flows equatorward along the coast. Under realistic geometry and bathymetry, the multiple-mouth Zambezi
River generates a surface-advected plume with diminished upstream penetration. The response to impulsive
winds leads to a change of shape into either a coastal current that moves equatorward along the coast or a
large bulge that spreads seawards and polewards, depending on the wind direction. Asymmetric sea-breezes
and tides deepen the plume, changing the plume structure from surface-advected to bottom-advected. The
implications of the model results for coastal fisheries and management are discussed.

Upwelling regions are areas of high productivity compared to other areas of the ocean. In fact, over 20% of
global fish catches occur in upwelling regions, although these areas occupy less than 1% of the surface of the
world's oceans. The aim of this study is to create a global map of the world to recognize the most important
upwelling systems, also determine how these systems have changed over the studied period (1982-2010)
studying their trends. Wind data were acquired from NCEP Climate Forecast System Reanalysis (CFSR). Wind
stress is the variable under study. The use of a very small resolution (0.3x0.3 degrees) stands out in this study
which permits a very important knowledge about the winds behaviour to characterize upwelling systems with
great precision. Also, this study has included all the regions previously studied, under the same conditions to
choose the most important and know their evolution. As a result the regions considered as upwelling systems
were: Benguela, Canarias, Venezuela, South Peru, North Peru, South California, North California, West
Australia, Java, North Kenia and Somalia-Yemen. It is not possible to establish a general behaviour between
the different systems because trends are variable depending on the system analysed.

River plumes control the patterns of nutrients, sediments and/or pollutants of fluvial origin on the coastal ocean
and can promote strong physical and chemical changes on seawater. These changes affect the biological
characteristics of the area, such as primary production, species composition, abundance and distribution of
existing microorganism dependent on river discharges. Thus, considering their high ecological impact, the
study of the plumes variability gains importance on the development of primary and secondary economic
sectors, as well as in several strategic socio-economic activities. The role of the main forcing drivers (river
discharge, wind and tide), on the turbid plumes of the most important Iberian rivers was studied using water
leaving radiance (nLw555) data obtained from the MODIS (Moderate Resolution Imaging Spectroradiometer)
sensor onboard the Aqua satellite, during 2003-2011. Composite images, interpolated to a regular pixel grid
with an approximate resolution of 500m, were obtained for days under certain conditions of river discharge,
wind regimes and tide. Results showed that discharge is the main forcing factor in river plume extension. Wind
effect is noticeable under high river discharge and tide is important for the estuarine outflow regimes, with
particular characteristics for each river.

The Minho River, situated 30 km south of the Rias Baixas, is the most important freshwater source flowing into
the Western Galician coast (NW of the Iberian Peninsula). The buoyancy generated by the Minho estuarine
plume is often responsible for a reversed circulation pattern inside the Rias Baixas, modifying the
macronutrients concentration available for the production. Numerical modelling constitutes an important tool
that may be used to study the Minho estuarine plume effects on the Rias Baixas under different conditions.
Thus, a set of three-one-way nested models (MOHID) has been coupled to a particle tracking model to analyze
the propagation of this plume. The influence of the Minho River discharge, wind forcing and changes in
morphology has also been studied on these coastal systems. According to the model results, the freshwater
discharge and wind has a significant impact on particle fate and dispersion. On the contrary, morphologic
estuarine changes do not influence significantly the particles pathways and final position. Under Minho River
3 -1
discharges higher than 800 m .s combined with southerly winds, an intense particles exchange between
estuaries was observed, as well as an inversion of the Rias Baixas circulation pattern.

Bottom water renewal is crucial for oxygen supply and removal of organic loadings at shellfish farms. This
study presents a 3D hydrodynamic model (MOHID) used to quantify deep water renewal at La Rochelle Bay,
France. Open boundary conditions were provided by the Mercator-Ocean analysis and forecast system, and
downscaled by using four nested domains with increasing resolution from the large to the local scale. Results
from a six-month run of the model were compared against data collected from the Naval Hydrographic and
Oceanographic Service (SHOM), giving a good agreement. The spatial variation of water renewal was
characterized by dividing the coastal waters into sub-volumes along the depth, named as Boxes. A lagrangian
model was coupled to the hydrodynamic model to track the history of water renewal. The boxes were filled with
tracers and the pattern of particles passing through them was quantified. Model results were integrated over
the volume of the boxes to calculate the water fluxes across box boundaries. The results of the integration
provided water budget, horizontal and vertical fluxes of water which were used to assess the renewal of deep
waters in the bay.

The Mediterranean Sea has been classified into homogeneous areas based on physical variables (salinity,
attenuation coefficient, nitrate concentration, sea surface temperature, photosynthetically active radiation and
significant wave height). They were obtained from three different sources: in situ measurements, remote
sensing or reanalysis database. Physical typologies were obtained by statistical analyses, combining two
clustering techniques: self-organizing maps (SOM) and K-means algorithm (KMA). The result was a division of
the Mediterranean Sea into six typologies. Two of these typologies were mainly coastal sites (typologies I and
III), characterized by low wave height and PAR values and distinguished by salinity. Typology VI was mainly
determined by high wave height. The combination of high temperature and salinity defined typology II,
meanwhile typology V was chiefly influenced by cold and productive waters. Results were in agreement with
the distribution of some endangered species, supporting the use of physical variables as surrogates for
biological diversity. In addition, to test the usefulness of the classification obtained as a tool in the management
of coastal areas, its sensitivity across different simulated climate scenarios were tested.

Origin, composition and land-ocean fluxes of particulate organic matter in changing coastal
environments

Observatoire Aquitain des Sciences de l’Univers, UMR 5805 EPOC, Université Bordeaux 1 / CNRS, Station Marine d’Arcachon, France
[email protected]
Particulate organic matter (POM) is a major compartment of the biogeochemical cycles. Actually, it is involved
in numerous fluxes as primary production, trophic transfer, remineralisation, export at depth, resuspension,
land-ocean export, etc. Coastal systems experience e.g. high nutrient inputs and strong (sedimentary)
hydrodynamics due to their position at the land-ocean interface and to their shallow water column. Thus, all the
POM-involved fluxes co-exist within a small zone and are enhanced there, compared to the open ocean. This
implies a highly diversified POM of different origins (terrestrial vs pelagic vs benthic origin) in coastal systems:
higher plants, macroalgae, microalgae, detritus of these primary producers and associated bacteria, etc.
However, depending on their origin and composition (and thus lability), POM is not similarly involved in the
different fluxes. Among the proxies useful for studying the POM origin and composition, isotopes have the
great advantage to quantify (through the use of mixing models) the relative composition of POM in units of
Carbon.
My talk will 1) explain the usefulness of isotopes for quantifying the POM composition, 2) present the POM
composition (and the composition of land-ocean POM fluxes) in a diversity of coastal systems, 3) describe the
environmental forcings to this composition, 4) discuss the evolution of POM and POM-fluxes composition in a
changing Earth, and finally 5) claim for long-term study and monitoring of coastal ecosystems.

Ultraviolet radiation (UVR, 280-400 nm) is an important environmental factor with significant effects on the
photochemistry and photobiology of the aquatic ecosystems. In order to assess the interactive effects of UVR
and external additions of allochthonous matter from continental and atmospheric origin, three different
experiments were performed along the year to assess the effects on the production of the planktonic
communities from Ría de Vigo (Northwest Spain). Samples with and without the addition of the allochthonous
matter were incubated under natural solar radiation during 48 h using a UV cut off filter (UV opaque, UVO
treatment) or a UV-transparent filter (UVT treatment). Phytoplankton photoinhibition by UVR ranged from 557% in UVT samples compared to UVO samples and was related to irradiance levels along the year. However
the sensitivity of phytoplankton to UVR was dependent on the characteristics of the additions with continental
additions increasing sensitivity to UVR but atmospheric additions decreasing sensitivity. Bacterial production
was less affected than phytoplankton by UVR and no clear patterns were observed regarding sensitivity to
UVR with the different external additions.

Corresponding author: [email protected] (T Yamamoto)
Nitrogen and phosphorus loads to Hiroshima Bay have been restricted by law for 30 years, the current
situation is believed to be "oligotrophic". Oyster production conducted in the bay has decreased 2/3 of the peak
production. Whereas iron is also one of the important elements which support biological production, almost no
information about iron concentration in the area is available. In the present study, dissolved iron concentration
was measured along the basin of the Ohta River to the Hiroshima Bay estuary in June, September and
November in 2013. The concentration was quite high (0.05-0.7 ppm) in the wetland located at the uppermost
area of the river, which was restored during 2003-2010 to original wetland from farmland. The concentration
decreased sharply at a dam located still in the upper stream, and further down in the lower river (0.01-0.05
ppm). In the estuary of Hiroshima Bay, the iron concentration was much lower (0.001-0.01 ppm) compared to
28
the concentration in the lower river. Chlorophyll a distribution showed an inverse relationship with dissolved
iron concentration in the estuary, indicating dissolved iron was consumed by phytoplankton and may be the
limiting factor of growth. Discussion will be made on which element is the limiting factor of biological production
in the bay.

In order to understand carbon and nutrients biogeochemical cycling in Tagus estuary intertidal sediments,
cores were collected in contrasting mudflats: Barreiro (BRR), subjected to high anthropogenic pressure,
Alcochete (ALC) under moderate/small pressure and Vale de Frades (VF) in Tagus natural reserve. Analyses
of pore waters organic dissolved carbon (DOC), humic substances, nitrate, ammonium, phosphate as well as
solid phase organic and inorganic carbon (OC and IC) and nitrogen, were carried out. Results showed that
BRR core average concentrations of DOC and OC were lower than ALC and VF (VF>ALC), but higher in
nutrients. Organic matter oxidation dominates in the top 5 cm layers for BRR site. Nitrification occurs in these
layers, where DOC decreases. The distribution of humic substances does not follow DOC pattern meaning
that organic carbon is reactive, easier to be oxidized. Lower OC values observed in these layers point also to
carbon mineralisation. In contrast, carbon accumulation was observed in ALC and VF sites. DOC and humic
substances similar profiles in top layers point to refractory nature of the organic matter present, resulting in the
accumulation of non reactive carbon. Thus organic matter oxidation is more difficult and nutrients accumulation
is observed in lower layers.

Hydrogen sulfide in eutrophic sediments is highly toxic to benthic organisms and may cause foul odor and blue
tide. Our field study revealed that high levels of hydrogen sulfide (75 mg-S/L) were observed in organically
enriched sediment collected from Oosaka Bay lying near one of the big metropolis in Japan. Therefore, it is
very important to remove hydrogen sulfide from sediments to maintain healthy ecosystems and support
sustainable aquaculture activities. To remediate enclosed water bodies, granulated coal ash was made by
mixing fly ash from coal electric power plants with cement. Granulated coal ashes with different mixing ratios of
fly ash and cement were prepared and evaluated in terms of hydrogen sulfide removal performances. The
removal rate of hydrogen sulfide accelerated with increasing mixing ratio of fly ash. On the one hand, when the
mixing ratio of fly ash exceeded 95%, the compressive strength of the materials was significantly decreased for
field application. In our presentation, we will introduce the hydrogen sulfide removal mechanisms of the
granulated coal ash and propose remediation strategies for enclosed water bodies using this material.

In this study we investigated the interactive effect of exotic macroalgae degradation and climate-driven
stressors on estuarine sediments nitrogen biogeochemistry. A set of microcosm experiments with estuarine
sediments were set up in order to manipulate temperature (15ºC/20ºC) and the decomposition of exotic and
native macroalgae. Changes in inorganic nitrogen compounds were evaluated over time by measuring the net
+
fluxes of NH4 , NO3 and NO2 , and ARISA technique was used to evaluate shifts on sediment microbial
composition. Our findings revealed a significant impact of the temperature on the processes involved in the
nitrogen recycling, since high temperatures promoted an increase on the release of NO 3 and NO2 to the water
29
column. While, no changes in the microbial communities were observed within the different temperatures and
macroalgae type (native and exotic), a microbial community selection occurred where Fucus vesiculosus and
Ascophyllum nodosum were present (p < 0.05, tested by ANOSIM). This two macroalgae belong to the family
Fucaceae, presenting chemical and physiological similarities that may explain these results. Our findings
suggested that high temperatures may cause a decrease on the efficiency of the nitrogen cycle, promoting a
possible uncontrolled growth of algae and consequently a dysfunction of the estuarine ecosystems.

The platinum-based anticancer drugs, cisplatin, carboplatin and oxaliplatin, are used extensively in the
treatment of various cancers. Their mode of action involves the formation of reactive species that combine with
DNA molecules, and the driver for this process is the change in chloride concentration between the plasma
and intracellular environment. With the greater incidence of cancer among a growing and aging population,
there has been an increase in the discharge of anticancer drugs to rivers and estuaries within the EU. In this
work, inputs and concentrations of Pt-based drugs in rivers and estuaries are assessed based on
administration data and concentrations measured in hospital effluents. The geochemical reactivity and toxicity
of the drugs have been studied in a series of carefully controlled laboratory experiments simulating estuarine
conditions. In response to chloride (or salinity) gradients and flushing times representative of macrotidal
estuaries, the drugs become more reactive (through adsorption to sediments) and toxic towards fresher
waters. These characteristics are greatest for cisplatin and are predicted to be more acute in times of high river
flow as reactive forms are propagated downestuary. Given that cytotoxic drugs are potentially harmful to all
eukaryotic organisms, further research into their environmental behavior is called for.

cohesive mud layer which covers the sand layer of the tidal flat. After the installation of GCA pile, the
concentrations of dissolved oxygen in the interstitial water in and around the GCA pile increased with
maximum concentration of 6 mg/l due to an enhancement of groundwater current. It was observed a decrease
in the concentration of ammonia in the interstitial water and increase in the individual number of benthos in the
GCA pile site, and these must be caused by the increase of dissolved oxygen in the interstitial water. Clogging
of the GCA pile by mud was not observed for 4 years. From these results, it is concluded that the GCA pile is
an effective technology for remediation of muddy tidal flats.

The different scenarios present in the Brazilian coast require studies of the carbon cycle considering the
biogeochemical characteristics of each area. This study was conducted in the shelf region of Recife, near the
outlet of the River Capibaribe, in the coastal region of Itamaracá, where a calcareous algae bank exist and also
around the archipelago of Fernando de Noronha, in open sea. Temperature and salinity were evaluated and
also pH, total alkalinity, the total CO2 and fCO2 were obtained. Salinity, sewage inputs and calcareous algae
banks act on solubility of the components of the carbonate / bicarbonate / carbon dioxide system. Fernando de
Noronha archipelago is under intense hydrodynamic while anthropogenic influence is observed nearest Recife
city and natural behavior is observed in algae bank in Itamaracá. The values ranged from 8.09 to 8.20; 1.668
to 2.111 µmol/kgsw; 1,333-1,956 µmol/kgsw; 186-279 µatm in Recife, 8.13 to 8.20; 1.675 to 2.321 µmol/kgsw;
1.546 to 2.134 µmol/kgsw; 216-259 µatm in Itamaracá and 8.17 to 8.20; from 1.594 to 2.228 µmol/kgsw; 1.447
to 2.216 µmol/kgsw; 177-419 µatm in Fernando de Noronha, for pH, TA, TCO2 and fCO2, respectively. In short,

natural and anthropogenic influences on the biogeochemical processes are linked to the balance between
components of the marine carbon system. (FAPESP 2011/50582-0).

Shifts in biodiversity and ecosystem functioning
Magurran AE
Centre for Biological Diversity, University of St Andrews, St Andrews, Fife KY16 9TH, Scotland, UK
[email protected]
Growing concern about biodiversity loss has sparked renewed interest in community structure. Ecological
assemblages invariably include both common and rare taxa; species abundance distributions (SADs) describe
these patterns. To predict how communities respond to anthropogenic change we need to understand the
processes that shape species abundance distributions. I will describe three approaches that help elucidate
these processes. 1) We can deconstruct assemblages into functional units within which species experience
similar selection pressures, and compete directly with one another for resources. It is in relation to these
functional units – spatial guilds – where we stand the best chance of making biologically meaningful predictions
about relative abundance. 2) We can focus on the fate of the populations that make up an assemblage.
Species that are under density dependent control will maintain their relative rankings and abundances through
time, thus providing the underlying framework in an assemblage. 3) We can quantify temporal turnover, relative
to the baseline predicted by null models and explore the mechanisms that cause communities to change more
quickly than would be expected by chance. These approaches shed light on how ecological communities
change through time, and in doing so reveal how shifts in biodiversity will affect ecosystem function.

How well do fish community-based measures of ecological quality track changes over time? The role
of anthropogenic vs climate-driven pressures

The development and use of indices capable of detecting anthropogenic impacts on transitional waters has
particularly increased in Europe over the last years, mainly due to the implementation of the Water Framework
Directive. In this work, we analysed the ecological quality of the Mondego estuary (Portugal) during a 10-year
period (2003 – 2012) using the Estuarine Fish Assessment Index (EFAI), and compared against an
Anthropogenic Pressure Index (API), which comprises a set of stressors that affect estuarine ecosystem
functioning. The objective was to determine whether or not the ecological quality based on fish assemblages
reflected the variation in anthropogenic pressures at the estuary (EFAI) and water body levels (EFAIwb). The
ecological status of the Mondego estuary was relatively stable (Good), with only one year classified as
Moderate (2006). At the water body level, lower ecological quality statuses were observed. No significant
correlations were obtained between the EFAI and EFAIwb with the API. The results revealed some difficulties
of this approach: the definition of anthropogenic pressures, the time frame and magnitude required for a
pressure to result in effective change, and the availability of data. The variability in ecological quality most
probably reflected the environmental/climatic changes over the selected time frame, rather than the
anthropogenic disturbance in the river basin.

European marine waters encompass several regional seas, such as parts of the North East Atlantic, Baltic,
Mediterranean and Black Seas that support a variety of valuable fisheries. However, the majority of
commercial fish stocks are considered to be over exploited in Europe. “Biodiversity” and the “Populations of
commercially exploited fish and shellfish” are two of the quality descriptors for assessing the good
environmental status (GEnS) under the European marine strategy framework directive (MSFD). However,
these are not independent as commercial fishing activities may alter the state of marine biodiversity. The
DPSIR framework was used analyse and to explore the links between the two descriptors. Commercial
fisheries are the main economic sector (DRIVER) and controlled by demand for seafood, economic conditions
32
of the communities and open access to the seas. Illegal and destructive fishing methods, ghost fishing,
overfishing, bycatches, noise and oil pollution are the main pressures. The study revealed that various groups
of organisms (zoobenthos, fish, marine birds, reptiles, marine mammals and submerged aquatic vegetation)
are being affected by commercial fishing. Exploring the links between these two descriptors is shows
significant interactions that may simplify the environmental assessment.

Knowledge on global patterns of fish species richness and on regulating variables is indispensable to develop
predictive models. A worldwide database was built based on published studies on fish communities in
estuaries as well as on environmental features; Generalized Linear Models with a Poisson distribution were
used to identify variables associated with the observed variation of species richness among estuaries, whilst
accounting for number of samples. At the global scale, species richness was related to the marine
biogeographic realm, and also increased with sea surface temperature (SST), width of the estuary mouth,
stability of connection to marine environment (open versus temporarily open/closed estuaries) and
precipitation, and was also related to continent (64% explained deviance). At smaller scales (i.e. individual
continents or marine biogeographic realms) other features were also important in predicting variation in
species richness, chiefly: species richness also increased with the area of the estuary or of the river basin.
Results revealed the variables behind macro-ecological patterns of fish species richness in estuaries, and
highlighted the overwhelming importance of considering different spatial scales and biogeography to
adequately identify these variables.

It is now widely established that, in recent decades, environmental changes at the local and global scales
threaten the very sustainability of several ecosystems by altering the structure of ecological communities and
the overall functioning of ecosystems. Estuarine and coastal ecosystems are particularly vulnerable to these
changes. Observed responses of biodiversity were, in many cases, non-linear. Threshold effects exist above
ecosystem which can undergo long-lasting reorganizations. Such shifts in ecosystem involve new responses
from communities to environmental factors. Impacts on estuaries of these abrupt changes are currently few
documented. Previous studies reported that the Gironde estuary experienced two abrupt shifts in the last 3
decades. In the present study, we intend to deeper explore impacts of local climate and hydrological
parameters on fish biodiversity between 1985 and 2012. Jointly use of standardized Principal Component
Analyses (PCA) and Generalized Linear Mixed Model (GLMM) have permitted to define 3 “inter-shift”,
ecologically stable, periods. Results indicate that environmental drivers influencing the Gironde estuarine fish
biodiversity changed over the three periods. Furthermore, the strength of the relationships between
environmental factors and fish community structure has changed between periods suggesting that the
ecosystem has experienced real ecological regime shifts during last decades.

Using a standardized monthly long-term database (1997-2012) of experimental beach seine data at shallow
water of estuarine and adjacent surf-zone areas of sub-tropical Patos Lagoon Estuary in southern Brazil (32ºS52ºW) we evaluated the main hypothesis that long-term changes in fish abundance and diversity occurred in
the last decades. The species composition (Total Species S=125) and catch per unit of effort (CPUE) of both
33
estuarine (S=95) and surf-zone (S=54) species were quite similar (similarity=52.1 ± 5.8 SD), but showed high
inter-annual variability that was mainly regulated by changes in oceanographic conditions. In the estuary,
species richness (S2002=45; S2012=22) dropped substantially, but CPUE variations were statistically non
significant (mean=92.3; Min2001=34.5; Max2000=163.4). In surf-zone, species richness vary but not
significantly (MinS1998=25; MaxS2010=17), but CPUE dropped substantially (mean=101.9; Min2012=31.3;
Max1997=221.5). Oceanographic conditions were important but habitat loss and the fishing pressure seem to
play important roles on observed long-term changes. Four species with "tropical" distribution (Harengula
clupeola, Polydactylus virginicus, Oligoplites saliens and Chromis flavicauda) were recorded since 2001 and
observed in at least two consecutive years, which may be an indication that warmer waters are remaining
longer along the RS coast, reinforcing the hypothesis of a possible 'tropicalization' of southern Brazil.

Environmental changes influence ecological communities by inducing changes and or shifts in their ecological
niches. Recent studies reported a ‘marinisation’ process in the Gironde estuary (France) i.e. a flow drop and a
correlated increase of marine salt water input in the area that impacted the structure of estuarine community.
An important consequence of this environmental change is an increase of marine species in the fish population
leading to a deep modification of the fish community. In this context the aim of the present work was to intend
to investigate synchronies, differences, and commonalities in fish species abundance trends in relation with
environmental factors using an innovative combination of analytical methods. Dynamic Factor Analysis (DFA)
was used to make a typology of fish species long term evolution and identify common trends. In a second time
General linear mixed models (GLMM) were implemented to find environmental drivers of each fish group. Four
groups of species with common trends over the last 30 years were identified with contrasted responses to
environment in relation with environmental shifts identified in previous studies. These results highlight that
deep changes in fish biodiversity can occur in the estuary in the context of global changes.

Patches of stranded algae (wrack) is a common feature on sandy beaches worldwide. Despite their relevance,
the spatial distribution of wrack debris on the shore and its potential influence on the distribution of upper shore
arthropods remain poorly understood. In this study, the amount and composition of wrack deposits as well as
community attributes (total density, species richness and diversity) were determined on sandy beaches located
in three distinct geographical regions: South (Parana) and Southeast (Rio de Janeiro) of Brazil and Southwest
of Spain. These parameters were compared between upper and lower wrack bands on each beach and
between beaches in each region. In all regions, beaches differed in the total amount of stranded wrack, but
their accumulation on the beach face (i.e upper and lower line) was similar between beaches. Wrack bands
shaped density of common taxa (Talitridae, Tenebrionidae, and Staphylinidae), with consequences in
communities structures. This result could be due to their preference for specific nnicrohabitats and food
sources, which might differ according to the relative age of the wrack bands. This study demonstrated that,
independent of wrack composition, the distribution of wrack deposits in bands play a role on the structure of
supralittoral arthropod assemblages.

Understanding recruitment is one of the most important goals in the study of marine benthic population
dynamics. Its study is difficult as it varies at different spatial and temporal scales. Chthamalus montagui is the
most abundant intertidal barnacle of the Portuguese coast and its recruitment (number of cyprids - last larval
stage - and juveniles that have settled and survived during a certain time after settlement) can be easily
monitored at different temporal scales. Recruitment of this species is very intense during summer. Several
years of observations of recruitment of this species on rocky shores located at the Cape of Sines (SW
Portugal) and at the lee of this cape revealed that there is a consistent higher recruitment at the lee of the
Cape of Sines. Larval supply has been shown to be correlated in time with recruitment and shores with a
higher recruitment had also a higher larval availability. Interannual variability of recruitment was observed at
the Cape of Sines, with a lower recruitment in colder (summer) years, while no consistent interannual/climatic
variability of recruitment was observed on shores located at the lee of this cape.

Anthropogenic disturbances may have impact on phytoplankton communities and changes in species richness
are frequently observed. A wide variety of biological indicators can be chosen to adequately assess these
changes. The present study investigates effective and reliable phytoplankton community indicators of changes
in water quality generated by dredging in an estuary. Changes in suspended particulate matter, turbidity,
dissolved Cr, Ni, Cu, Cd, Hg and Pb concentrations, and phytoplankton biomass and composition are reported
for a 5 month period dredging operation, in a trace element contaminated area of the Tagus estuary (Portugal).
Phytoplankton biomass, diatom:other groups ratio, benthic:pelagic diatom ratio, Margalef’s, Simpson’s
diversity, Shannon-Wiever’s, and Warwick and Clarke´s taxonomic diversity and distinctness indices, and
individual taxa were investigated as indicators of dredging induced changes. Significant rise in sediment
resuspension and trace element mobilisation caused by dredging influenced the community structure but not
the overall biomass. Benthic diatom displacement into the water column maintained species diversity, and
therefore, none of the indices highlighted community changes. Contrastingly, diatom:other groups ratio and
benthic:pelagic diatom ratio were reliable indicators for the assessment of dredging induced changes. A shift in
composition towards species less susceptible to trace elements was observed, disclosing some individual taxa
as potential indicators.

Kelps (large brown seaweeds) are conspicuous elements of the Portuguese coast, although kelp abundance is
declining, especially at central and southern Portugal. While many studies point out increased seawater
temperature as the main factor explaining kelp decline, little attention has been given to top-down (predatory)
influences. Through in situ experiments, we tested how herbivory affects the distribution and abundance of
35
kelp recruits. We compared the abundance and survivorship of recruits, the intensity of grazing on recruits and
the abundance of herbivores between Viana do Castelo (northern Portugal) and Peniche (central Portugal). In
addition, through an outdoor mesocosm experiment, we disentangled the independent and interactive effects
of both seawater temperature and nutrients on kelp recruits performance (mortality, growth, C, N and
carbohydrate contents, and photosynthetic potential and efficiency). Our main results showed that herbivores
and herbivory intensity is higher at central compared to northern Portugal and that the growth of juvenile
sporophytes was larger under a high-nutrient scenarios, particularly when temperatures were low (12, 15 ºC).
Despite the fact that the presence and fitness of kelps across southern European waters has been exclusively
linked to bottom-up influences, our results highlight the importance of top-down effects for kelp survivorship
and performance.

Microplastics are marine environmental contaminants of high concern in relation to both environmental and
human health. Recent studies have been showing that microplastics are able to modify the toxicity of other
environmental contaminants to marine organisms but more knowledge is needed to support environmental risk
assessment and management actions. To contribute to the paradigm, the influence of microplastics on the
toxicity of copper, a common environmental contaminant of estuaries and other marine ecosystems, to the
marine microalgae Tetraselmis chuii was investigated. Laboratory bioassays were carried out with copper
alone and in mixture with microplastics. In the range of copper and microplastics tested (ppb) a significant
reduction of T. chuii populational growth was observed in both conditions, with some differences. These
findings indicate adverse effects on producers potentially affecting the whole ecosystem. Implications for
environmental risk assessment of environmental contaminants and climate changes are highlighted

The influence of freshwater flow on bacterial communities in the estuarine system Ria de Aveiro (Portugal) was
investigated at two sites differently impacted by river inputs, representative of the marine and brackish water
zones of the estuary. Sampling events were clustered based on hydrological features. The hydrodynamic was
simulated with a Lagrangian model and related to microbiological parameters. Estuarine bacteria responded to
different freshwater regimes developing distinct patterns of abundance and activity at the marine and brackish
water zones. A circulation pattern induced by high river inflow produced vertical stratification in the marine
zone, promoting a seaward flux of bacterioplankton, and stimulating the import of riverine phytoplankton and
particle-attached bacteria to the brackish water zone. Advective transport and resuspension processes
contributed to a 3-times increase in abundance of particle-attached bacteria during intense freshwater inputs.
Additionally, bacterial activity in the estuary was controlled by inorganic nitrogen, responding to different
freshwater inputs, which, in association with different prevailing sources of organic substrates induced
significant changes in bacterial production. The dynamic and main controlling factors of bacterial communities
are clearly impacted by freshwater inputs. Therefore, significant changes in the recycling of nutrients by
microbial activities can be expected from alterations in freshwater inputs either related to global climate change
or regional hydrological regimes.

Coastal oceans are known to receive increasing inputs of reactive N as a result of the anthropogenic alteration
of N cycling. The responses of coastal microbial communities are expected to depend not only on the
magnitude, but also on the nature of these inputs. In order to assess short-term responses in microbial
plankton community composition from the Ría de Vigo (NW Spain) to increasing amounts of natural inputs of
matter, we conducted 3 microcosm experiments in spring, summer and autumn. Surface seawater was mixed
with 0% (control treatment), 1 %, 5%, and 10% of natural matter concentrates from continental and
atmospheric origin, and incubated during 48 h under solar radiation including UVR. Changes in bacterial and
eukaryotic pico-, nano- and microplankton were analyzed by ARISA (automatic rRNA intergenic spacer
analysis) and specific primer sets. Bacterial and eukaryotic plankton community composition at the end of the
experiments was clearly determined by the initial microbial assemblage. Changes in bacterial community
composition were dependent on both the amount and the nature of the added matter. Eukaryotic picoplankton
showed fewer changes in community composition than the larger eukaryotic size fraction and was more related
to the quantity than to the origin of the inputs.

This work aims to describe intertidal macroalgae patterns, at small spatial and temporal scales, studying the
ability
and
usefulness
of
pattern-based
biodiversity
surrogates
(both
taxonomical
and
morphological/functional), to monitor marine environments. Firstly, macroalgae populations were sampled in
terms of species richness and respective coverage, along different intertidal zones (upper, mid and lower),
wave exposures (sheltered and exposed facies) and time of sampling (monthly, three spring/summer months).
Secondly, pattern-based biodiversity surrogates were studied, namely using other taxonomical levels (Family
and Order) and using both common and recent approaches of morphological/functional groups described in
literature by Steneck and Dethier (1994), by Orfanidis et al. (2011) and by Balata et al. (2011). The studied
macroalgal assemblages showed important spatial changes in structure (coverage per specie) in terms of
zonation patterns (upper, mid and lower intertidal) and in terms of wave exposure (except for upper intertidal).
As expected, the spatial pattern of the macroalgal assemblages obtained by using species was more or less
consistent according to the different species’ surrogates utilized. In general, although each biodiversity
surrogate was able to distinguish distribution patterns among intertidal zones, this was not so evident when
distinguishing between macroalgae assemblages under different levels of wave exposure.

Benthic communities of intertidal and subtidal habitats in the European Wadden Sea have been subject to
increasing human impacts, rising sea level and increasing sea-surface temperatures. In the Jade Bay, a tidal
bay in the German National Park of Lower Saxony, we compared the present benthic macrofauna distribution
in the intertidal and subtidal with historical data of about 80 and 60 years ago and detected significant changes
in species composition and dominance structure. Intertidal mudflats originally dominated by the bivalve
Scrobicularia plana and the amphipod Corophium volutator are now dominated by the oligochaete Tubificoides
benedii. Seagrass beds decreased by about 50% from the 1930s to the 1970s, but increased threefold since
the 1970s. The destruction of subtidal Sabellaria spinulosa-reefs and associated fauna between the 1950s and
1980s mainly caused by dumping activities resulting in long-lasting temporal changes in the physical and
sedimentological properties. In contrast, the dominance of opportunistic and pelophilous species increased
since the 1990s. It is concluded that human impacts (dumping activities, eutrophication) mainly contributed to
temporal changes in macrofauna community structure between the 1930s and 1980s while climate change and
sea level rise are now major drivers.

Mortality and behavioral activity of the bivalves Scrobicularia plana and Cerastoderma edule were evaluated
under a wide range of salinity and temperature values during 120 h laboratory assays. Specimens were
sampled in the Mondego estuary (Portugal), acclimated and exposed to 8 salinity treatments (0; 5; 10; 15; 20;
25; 30; 35) at constant temperature (20ºC), and to 8 temperature treatments (5; 15; 20; 23; 26; 29; 32; 35 ºC)
at constant salinity (20). Organisms were fed daily. Mortality and individual activity were registered every 12 h.
Both species were mostly affected by lower salinity (S. plana: LC 50 = 5.35; C. edule: LC 50 = 11.09), showing
the highest mortality at 0 and 5 treatments; and by higher temperature values (S. plana: LC 50 = 28.86; C.
edule: LC 50 = 28.01), with highest mortality at 32ºC and 35ºC. Activity was evaluated through 4 main
behavioral features (burrowing; siphon activity; foot activity; reaction) and both species showed higher activity
in the middle of the range of salinity (max ~25) and temperature (max ~20 ºC), decreasing towards the
extremes. Therefore, extreme climate events (e.g. floods, heat waves) may in fact severely impact these
species, through drastic changes in salinity and temperature.

There has been growing evidence that gelatinous blooms are increasing in frequency and persisting longer
than usual. This tendency has been successfully related with climate fluctuations and large-scale indexes as
NAO. The impact of biological, hydrodynamic and large-scale climatic variables on the jellyfish community of
Mondego estuary was assessed from 2003 to 2010. Siphonophora Muggiaea atlantica and Diphyes spp. were
the main jellyfish species present in the estuary. Jellyfish density was generally higher in summer and since
2005 an increased tendency has been observed. Community analysis pointed out Acartia clausi, estuarine
temperature and salinity as the main driven forces for the summer assemblage’s structure. Also, chlorophyll a,
estuarine salinity, runoff and Sea Surface Temperature were identified as the major environmental factors
influencing Muggiaea atlantica and Diphyes spp. summer interannual variability. Jellyfish density increase
could not be directly related with the NAO index, though the relationship with temperature was evident. This
study represents a contribution to a better knowledge of the gelatinous plankton, a topic that lacks baseline
studies. Also, with the increase tendency of extreme weather events, it is essential to determine in what extent
these events affect plankton communities and the upper trophic levels and ecosystems function and resilience.

In face of the increasing anthropic and climate change pressures, the ecological preservation and impact
assessments of transitional environments are imperious. This study, applied to Ria de Aveiro in the north
Portuguese coast, allows a new insight of the potential climate change impacts in the seasonal ecological
equilibrium through the Venice System scheme application. Salinity fields are obtained using a validated
circulation and transport model (MOHID) for reference conditions and for three future scenarios (end of the XXI
century). Future scenarios combine reference and projected mean sea level and freshwater discharge, being
adopted the A2 IPCC scenario. Physical zonations are identified from mean salinity fields estimated with each
established scenario. As a result of projected sea level rise of 0.42 m and freshwater discharge reduction of
~22% in wet season and ~87% in dry season, an expansion of the Euhaline zone with the inland displacement
of all the other physical zones is projected. Species and habitats will be forced to readapt to these new
conditions. The ones with saltier tolerance are expected to occupy more extended regions, with their
dominance reinforced, while freshwater species will have to retreat, mainly in dry season.

A long term ecological research program (LTER) is developed monthly at the Guadalquivir estuary since 1997.
Inter- and intra-specific euryhalinity differences both in prey and predators seem to determine spatial species
distribution at this important nursery area: the less euryhaline species (marine recruits) tends to occur at
physiologically more favourable salinities (lower osmotic stress and mortality risk); whereas most euryhaline
species (estuarine species) occurred at ecologically more favourable salinities (lower inter-specific competition
and predation). Likewise, inter-specific differences in spawning periods cause certain temporal segregation of
those marine recruits using the estuary. High spatiotemporal coincidence of prey (mainly mysids and
copepods) density peaks with that of their predators suggests food availability as a key factor in the estuarine
nursery function. According to their distribution, the estuarine stretch situated seaward from the 5 isohaline
position is mainly used as a nursery ground, principally during warm period (T > 15 °C). Thus, human
management of the freshwater input to the estuary (from a 110 km upstream dam) modifies the nursery ground
extent due to seaward/upstream displacements of the estuarine salinity gradient. During droughts, this
freshwater control may also lead to a partial loss of the estuarine nursery function due to a decrease of prey
availability linked to extremely high-turbidity events.

Trends in abundance, temporal occurrence and spatial distribution of non-indigenous species (NIS) are
included as an indicator to assess the compliance of Good Environmental Status in the European Marine
Strategy Framework Directive. Available regional and national databases for NIS will be useful for the
implementation of the Marine Strategy but there are still spatial gaps for some regions. In 2009 Portugal was
among countries with the lowest reported numbers of NIS and no national online database on NIS. This study
provides an updated list of NIS registered in Portuguese coastal and estuarine waters, including mainland
Portugal and the Azores and Madeira archipelagos. A list of 129 NIS was catalogued for the Portuguese
estuarine and coastal aquatic systems, most of which registered in the last three decades, showing that this
area of the North Atlantic is not less prone to introductions than neighboring areas. Some case studies of NIS
registered in different habitat types are shown to demonstrate the temporal and spatial trends of some wellestablished populations.

Three major anthropogenic parameters have affected the biodiversity of the eastern Mediterranean in the last
two decades: global warming, the invasion of thermophilic biota through the Suez Canal, and heavy fishery
activity. Over 100 alien fish species have been reported from the eastern Mediterranean, 92 of which entered
39
through the Suez Canal. The present study, carried out from 2008 to 2012, compares the biomass proportions
of alien and native species at different depths, their trophic signature, and weighted trophic levels on shallow
(<40m) soft-bottom habitats along the Israeli coast. The study has revealed: a) a tropicalization of the coastal
systems (aliens comprise 60% to 90% of the total biomass); and b) significant changes in the food web. While
the trophic signatures of larger regions, such as the Baltic Sea, the Black Sea, the North Sea, and others,
peaked at 3.2 (Froese et al., 2005 Belg.J. Zool., 135:139-143) the trophic signatures of the East-Mediterranean
fishes (aliens and natives) peaked at 3.7. The ongoing replacement of the native fish by aliens is expected to
increase the overall weighted trophic level of the alien fishes, and thus may significantly affect the entire food
web in the eastern Mediterranean.

Blackfordia virginica, a non-indigenous hydrozoan introduced in many estuaries around the world, has been
observed in the Mira estuary, southwest of Portugal, since 1984. Examination of the gut contents of B. virginica
medusae revealed that copepods, the most abundant group in the plankton community, were highly predated.
Barnacle nauplii, anchovy eggs and decapod larvae were also identified in the guts. The medusae showed
positive selectivity for anchovy eggs and decapod larvae, while barnacle nauplii were negatively selected. The
mortality rate of copepods (used as a model prey group) induced by medusae predation was estimated
(4.22/day) and showed the potential impact of this species in the ecosystem. Monthly sampling (January 2013
- January 2014) at a fixed location of high abundance of the medusae confirmed the occurrence of a seasonal
cycle associated with temperature and photoperiod. Medusae were observed from May to December with peak
abundances in September (76 medusae/m3), which did not coincide with peak abundances of zooplankton
preys, registered during April.

The eutrophicated eastern Gulf of Finland is characterized by extensive cyanobacterial blooms, which are
strongly regulated by internal nutrient loading (phosphate release from bottom sediments during hypoxic
events). In 2008–2009 the eastern Gulf of Finland was impacted by large-scale invasion of hypoxic-tolerant
polychaetes Marenzelleria arctia, which become the dominant component of soft-bottom communities. The
mass development of polychaetes resulted in drastic increase of biomass of macrozoobenthos. Invasion was
followed by an increase of nitrogen/phosphorous ratio in water column, apparently because of the increase of
phosphorus retention in bottom sediments due to bioirrigation activity of polychaetes favoring the deeper
penetration of oxygen into sediments. The higher nitrogen/phosphorous ratio triggered the successive changes
in the plankton. The cyanobacteria, especially colonial nitrogen-fixing species, lost their competitive advantage.
Their abundance declined resulting in reduction of total biomass of phytoplankton and chlorophyll-a
concentration. The disappearance of large non-edible and/or toxic colonies of cyanobacteria improved the food
supply for zooplankton. The development of zooplankton and benthos produced the rich food resource for fish.
It is concluded that Marenzelleria invasion leaded to cardinal reconstruction of whole ecosystem which can be
recognized as regime shift.

The Manila clam Ruditapes philippinarum, native from the Indo-Pacific region, is one of the most exploited
bivalve in the world due to its highly adaptive capacity to variable environmental conditions. Overfishing and
low yield of native European clams motivated the introduction of R. philippinarum into Europe for aquaculture
purposes and it is currently widely distributed around the world. The occurrence of this species is known in
estuarine Portuguese systems since the beginning of the 80’s but only in the last decade the population has
been established in Tagus estuary where it is intensively exploited due to its wide distribution along this
estuary and high abundances in some areas. This study was carried out at the Seixal bay, where the Manila
clam has high abundances. Benthic invertebrate samples were collected during 2009 and 2010, to assess
spatial and seasonal distribution patterns and its relationship with the environmental conditions. The results
showed that sediment grain size and tidal exposure were the most important factors determining benthic
spatial patterns, with significant differences between intertidal and subtidal communities. R. philippinarum was
the dominant bivalve species in subtidal areas during all seasons and the population structure indicated the
occurrence of successful reproduction.

The coastal protection provided by seagrasses depends on their biological structure and functions within the
ecosystem and it is related to their capacity to attenuate waves, reduce current velocities and promote
sediment stabilization. To increase our predictive capabilities on the response of seagrass meadows to climate
change the habitat suitability of Zostera noltii was modelled at the Bay of Santander (Northern Spain). The
results obtained allowed to characterize and map the distribution patterns in relation to different environmental
variables and to forecast changes in the patterns resulting from the climate change. The suitability map was
defined by two classification techniques SOMs (self-organizing maps) and K-means algorithm, using as
predictors the main local hydromorphological variables determining seagrass growth and distribution (e.g.
water column height, current velocity, sediment characteristics, etc.). The approach developed provided an
overall view of the changes on the habitat distribution of Z. noltii in response to different scenarios of climate
change, identifying areas with favourable, stressful and unfavourable conditions for the settlement of
seagrasses.

Phytoremediation is an alternative to recover contaminated areas, such as estuarine ones. Autochthonous
bioaugmentation can be used to potentiate phytoremediation by plants through symbiotic association with
rhizosphere microorganisms. However, due to the toxic features that most metals present, it is important to
evaluate how the microbial communities are affected by metals and by autochthonous bioaugmentation. The
aim of this work was to evaluate the effect of copper on the microbial communities associated to the roots of
the salt marsh plant Phragmites australis with or without autochthonous bioaugmentation application. Plants
with their rhizosediment were collected in an estuarine area and placed in vessels. Sediments were
-1
contaminated with Cu (ca. 270 µg.g ) and an autochthonous microbial consortium resistant to Cu (prepared in
the laboratory) was added to half of the vessels. Vessels were kept in greenhouses for two months, under tidal
simulation. Analyses are still in course to determine differences in terms of microbial community structure
(evaluated by ARISA) and microbial abundances (estimated by DAPI). Results will be important for the proper
implementation of phytoremediation in estuarine areas.

Shifts in the structure of the microbial plankton community and its relation to the pelagic metabolic balance
were investigated in the Ría de Vigo to establish the trophic status of the ecosystem. Daily cruises to collect
seawater for size fractionated chlorophyll, in situ fractionated 14C primary production and in situ oxygen
production respiration incubations were seasonally carried out. Contrasting environmental conditions were
captured during the four sampling periods. Winter was characterized by a well-mixed water column. Intense
runoff modulated the spring hydrographic conditions, while the summer cruise corresponded to a spin down of
an upwelling event. Finally, the autumn was characterized by warm and relatively low saline waters. Microbial
plankton community was dominated by small size phytoplankton during winter (>70% of primary production),
shifting to the prevalence of large size phytoplankton for spring and summer cruises, and changing again to
prevailing small size phytoplankton in autumn. In spite of the variability in the microbial plankton structure the
system was always autotrophic; the highest degree of autotrophy (Net community production of 721 mmol O 2

The response of coastal phytoplankton to natural inputs from continental and atmospheric origin was assessed
through addition experiments carried out in the NW Iberian coast. Phytoplankton biomass and production
either increased or remained unaltered in the three experiments conducted along the year. Differences
between the effect of continental and atmospheric inputs were significant. When growth stimulation was
detected, the responses were linearly dependent on the magnitude of nutrient additions. Parallel controlled
experiments were performed by exposing the microbial plankton to known concentrations of inorganic (nitrate,
ammonium and phosphate), organic nutrients (glucose and amino acids) and a mixed treatment combining the
previous additions. Four types of responses were recognized: 1) no significant response to any treatment, 2)
Positive effect of inorganic and mixed treatments, 3) enhanced phytoplankton growth associated to mixed
additions but not to inorganic inputs and 4) slight positive effect of inorganic and mixed treatments and
depression of phytoplankton growth in the organic treatment. These results are interpreted on the basis of
nutrient concentrations and stoichiometry and the interaction between phytoplankton and heterotrophic
bacteria. We conclude that to predict the effect of allochtonous nutrient inputs on planktonic primary producers,
a profound understanding of the autotrophic-heterotrophic coupling is required.

Although saltmarsh habitats in Australia have been considered as less important to estuarine fishes than
mangroves and seagrass, recent studies indicate that some fish rely on inundated saltmarshes for shelter from
predation and as a food source. The present study used a fine-mesh seine net to quantitatively sample the fish
communities in waters just outside saltmarshes in Empire Bay Wetland, Australia, to better understand their
density and diversity, paying particular attention to fish that use saltmarsh while inundated (e.g. Ambassis
jacksoniensis). Stomach-content analyses were also used to investigate contributions of saltmarsh-derived
food to A. jacksoniensis. Fish communities were dominated by three species (Pelates sexlineatus,
Mugiliogobius platynotus and A. jacksoniensis), and patterns of abundance and diversity of these communities
are interpreted in light of previous studies. The study also demonstrated that saltmarsh-inundation had minimal
effect on fish communities or on abundances of selected species. While it was previously thought that A.
jacksoniensis fed exclusively on saltmarsh-derived crab zoeae, diets of A. jacksoniensis displayed prey
switching from crab zoeae, when saltmarsh was inundated, to carids when they were not. This is in contrast to
previous findings where A. jacksoniensis starved at such times. These contrasts highlight the ecological
variability of estuarine environments.

Bifurcations in marine ecosystems: concurrent recruitment collapses in gadoid fishes and changes in

Corresponding author: [email protected] (T Johannessen)
Repeated incidents of abrupt and persistent recruitment collapses were observed in a unique time series
(since 1919) of 0-group gadoid abundance data from the south coast of Norwegian. The incidents were
attributed to gradually increasing nutrient loads and in one instance to increasing temperature. Based on
comprehensive testing in the field and concurrent abrupt changes in the plankton community with that of the
recruitment collapses, it was concluded that the underlying mechanism was abrupt shifts in the plankton
community, which was propagated to higher trophic levels by causing recruitment failure in fishes. Such shifts
can be classified as bifurcations, that is, abrupt and persistent ecosystem shifts resulting from gradual
environmental changes that affect several trophic levels. Prior to the events there were no warning signals to
suggest that shifts were imminent. After the shifts, that occurred ~85, 50 and 15 years ago, there have been no
sign of recovery, nor have other fishes replaced the gadoids. The indication that increasing temperature may
render marine ecosystems vulnerable to bifurcations is highly worrying at the prospect of global warming.

Anthropogenic pressures are changing the magnitude and nature of matter inputs into the ocean. The Ría de
Vigo is a highly productive and dynamic coastal system, likely affected by such alterations. Previous
microcosm experiments conducted during contrasting hydrographic conditions suggested that heterotrophic
bacteria appear to be carbon limited in this coastal area, as they never responded to inorganic (N, P) additions,
but positively responded to organic (C, N) and mixed (inorganic plus organic) additions. In order to assess
short-term responses in production and respiration of heterotrophic bacteria from the Ria de Vigo to increasing
amounts of natural inputs of matter, we conducted 3 microcosm experiments, where surface seawater
collected in spring, summer and autumn was mixed with 0% (control treatment) to 10% of natural matter
concentrates from continental (riverine discharge) and atmospheric (dry and wet deposition) origin. Bacterial
production responded to continental inputs only during summer, whereas positive responses where observed
for atmospheric inputs during summer and autumn. No significant responses where observed for bacterial
respiration and bacterial growth efficiency. Simultaneous experiments with controlled inorganic and/or organic
additions suggest that bacterial response largely depends on the initial nutritional state and the C and P
content of the natural inputs.

Ocean margins represent a minor percentage of ocean’s surface but are responsible for over 20-50% of global
primary production. Susceptibility to changes imposed by human activities in the natural cycles of the different
elements, namely nutrients, are especially relevant in coastal areas. To understand the response of
phytoplankton coastal communities to different levels of nutrient inputs from different sources, a microcosm
experiment was conducted in the Ría de Vigo. Three nutrient addition experiments were performed in spring,
summer and autumn, covering different environmental conditions and phytoplankton composition. At each
experiment, increasing levels from 0 to 10% of natural matter from atmospheric and continental inputs were
added to surface seawater. After 48h of incubation at natural light and controlled temperature, pico-, nano- and
43
microphytoplankton abundances, chl a concentration and primary production rates were measured and
compared with those for the initial seawater sample, without additions. Responses in Chl a and primary
production to nutrient inputs from both atmospheric and continental sources varied among seasons. Despite
this variability in Chl a and primary production levels, picophytoplankton was not affected by these nutrient
inputs. Thus, our results indicate that potential eutrophication of this coastal system would mainly affect the
largest phytoplankton size fraction.

Salt marshes occur in low-energy environments, being the halophytes communities spatially distributed
according to the marsh’s topography. These ecotones are highly productive environments that play a key role
in carbon and nutrient cycling and carbon sequestration. Their gross primary production allows a great
reduction of CO2 in the atmosphere, production of organic carbon through photosynthesis and ultimately, C
retention in the rhizosediment. Moreover, nitrogen incorporation in salt marsh plants’ biomass (N
fixation/primary production) gives them the ability to auto-remediate estuarine systems. As important C and N
sinks, they provide ecosystem functions supporting key ecosystem services (e.g. habitat, shore protection, gas
regulation, water purification, bird watching). At the same time salt marshes are classified as sensitive habitat
under the European Habitats Directive, and have been proposed as one of the biological indicators in the
scope of the Water Framework Directive. The Ria de Aveiro, a coastal lagoon located along the Atlantic Ocean
on the northwest coast of Portugal, contains one of the largest salt marshes in Europe. The present work
assesses the role of the sea rush Juncus maritimus in the Ria as C and N sink, and its contribution to overall

Many species of primary producers grown in cultures have been reported to be auxotrophic for B-vitamins.
However, little is known on role of these organic compounds on the control of natural phytoplankton
assemblages. Recent studies carried out by our group in a coastal system demonstrated that, under certain
circumstances, stimulation of phytoplankton biomass and production after additions of inorganic nutrients only
occurred when heterotrophic bacteria were active, presumably releasing organic molecules required by
microalgae. In this investigation, we tested the hypothesis that B-vitamins could be a limiting factor for
phytoplankton growth in coastal systems in some oceanographic periods. We report for the first time direct
measurements of dissolved B-vitamins in the coastal system of the Ria de Vigo (NW Iberian Peninsula).
Samples were collected monthly at different depths. On each sampling date, we conducted bioassays where
natural water samples were exposed to experimental addition treatments: a) inorganic nutrients (nitrate,
ammonium and phosphate), b) Vitamin B12 and c) a mixture of treatments a and b. Phytoplankton chlorophyll,
pico and nanoplankton abundance and heterotrophic bacterial abundance was monitored. The temporal
variability observed in the phytoplankton responses was related to changes in ambient nutrient concentrations
and in the structure of the microbial web.

Understanding estuarine habitat use by larval fishes is crucial for their effective conservation and integrated
estuarine management. Stable carbon and nitrogen ratios were used to investigate the feeding ecology of
44
larvae Pomatoschistus microps (Krøyer, 1838) in four areas within two ecosystems of the Portuguese coast,
the Lima and Minho estuaries, over four seasons (from July 2012 to June 2013). At each season and area,
within the two estuarine sites, the fish larvae of two size classes (class 0: 0 - 10 mm; class 1: 10 - 15 mm),
phytoplankton [based on particulate organic matter (POM)], and pelagic zooplankton were collected. The
contributions of different food sources to the consumers were assed using the isotopic mixing model SIAR
(Stable Isotope Analysis in R). The stable isotope data indicated that i) the food web structure was similar
among sites, areas and seasons, and the copepods Acartia sp. were the main source of food to the larvae
common goby, with no significant differences between consumers' size classes; ii) higher nitrogen isotopic
ratio found in the Lima estuary, for consumers and sources, revealed anthropogenic inputs of nutrients into this
system when compared to the Minho estuary, and that the trends changed throughout the year.

Climate change affects species distributions, biological processes and trophodynamics in aquatic ecosystems.
Its impacts are difficult to understand because of its synergistic action with anthropogenic pressures and its
often subtle indirect effects. The oyster, Crassostrea gigas, was introduced for farming in the 1970s along the
French Atlantic coast and represents nowadays 98% of the aquaculture activity. In the 2000s, Arcachon Bay
was considered as the first spat-supplying area providing the spat of 70% of the French oyster production.
During the last 16 years, the local economic activity of spat production has been threatened recurrently due to
a high interannual variability of seed harvesting. This threatened spat production was attributed to reproductive
problems highlighted by both an oyster spawning delay and a decrease of small larvae abundance since 1995.
Long-term series available since 1987 showed that both spawning delay and small larvae abundance are more
related to a North-Atlantic hydro-climatic index, the Atlantic multidecennal oscillation, than to local changes in
temperature. This index might control the phytoplankton communities of the Bay, through hydrodynamic
changes. Actually, a shift of phytoplankton community structure is observed in 1995 that made the diversity of
consumed species lower in recent period.

Lake St Lucia, Africa's largest estuarine lake system, has recently experienced an unprecedented crisis
resulting from freshwater deprivation. This decade-long dry phase recently came to an end as increased
rainfall in the region, coupled with the reconnection of the Mfolozi River with Lake St Lucia, resulted in
significant freshwater input into the system. This study therefore aimed to investigate changes in zooplankton
community structure, as the system transformed from a hypersaline to an oligo/mesohaline state. Not only did
the increased freshwater supply introduce a number of freshwater taxa into the system, but the connection with
the ocean via the beach spillway allowed marine recruits to once again enter St Lucia, increasing the overall
diversity of the system. Most notable though, was the shift in community structure with the commencement of
the wet phase. The cyclopoid copepod Oithona sp. appeared in high densities throughout the lake system,
often more abundant than the dominant species during the dry phase: the mysid Mesopodopsis africana and
the calanoid copepods Pseudodiaptomus stuhlmanni and Acartiella natalensis. This study not only emphasises
the importance of the Mfolozi connection, but also contributes significantly to the overall understanding of the
system's ecology, especially in response to climatic shifts.

Benthic foraminifera have a wide distribution in space and time and also respond rapidly to environmental
changes. The northern Alboran Sea is influenced by a torrential regime with sporadic, intense rainfalls and
extended periods of aridity. In addition, anthropogenic activities such as river channel deviation have taken
place during the last ca. 150 years. In order to understand the interaction between natural and anthropogenic
impacts through time, shifts of most abundant benthic foraminiferal species, species richness and diversity
indices were combined with sedimentological analyses and radiocarbon dating of sediment cores collected
from the Adra shelf prodeltaic deposit, in the northern Alboran Sea. The strong variations of benthic
foraminiferal assemblages involving significant population density changes occurred until ca. 1870 AD, and are
interpreted as response to natural processes. Low population densities correlate with rainfall-driven periods of
increased sediment supply to the shelf. In contrast, intervals with increased population densities, followed by a
raise of successful colonizers and opportunistic species, indicate the establishment of an environment with
new ecological constraints. After ca. 1870 AD, the impact of anthropogenic activities with the deviation of the
main river course to the east, are responsible for a drastic reduction of sedimentation rates in the study area.

Corbicula fluminea is one of the most important freshwater non-native invasive species that shows a wide
salinity tolerance and is able to occupy the upper reaches of estuaries. The species can replace native bivalve
populations with severe effects on biodiversity and in the ecosystem functioning. A 6-day mesocosm laboratory
experience was performed in order to assess the contribution of different size classes of the invasive species
C. fluminea for the ecosystem functioning at different salinities (0 and 5) and temperature regimes (20ºC and
30ºC), mimicking global change consequences. Sediment bioturbation (ecosystem process) and associated
nutrient release (PO4-P, NO3-N and NH4-N) were measured. GLS models were used to infer on the effect of
Corbicula size, salinity and temperature changes. The species showed a maximum sediment mixing depth
near 3 cm. All variables were important for the nutrient dynamics. However, size was the most influential factor.
Despite the equivalent biomass in each size-class treatments, nutrient release was higher in the small and
medium sized Corbicula mesocosms and enhanced by temperature increase, as a result of increased
sediment disturbance (bioturbation).

Studies on climate change impacts on coastal marine biota are scarce at a global scale and very few have
been focused on marine invertebrates. Cephalopod play a pivotal role in marine trophic webs, and most are
defined as ‘keystone’ species due to their strong influence on ecosystem dynamics. Here, we use ensemble
forecasting to examine global potential changes in coastal cephalopod species richness and assemblage
composition (i.e., species replacement or nestedness) from 1990-1999 (baseline period) to 2040-2049 (future
period) under IPCC A1B scenario and the ocean circulation model ECHAM5/MPI-OM. Mid-century projections
46
show little variation with regards to the baseline period. Greater losses are projected in the tropics (between
the 30ºN and 30ºS) and gains are expected at high latitudes (>40ºN and >40ºS) thus leading to smoothing of
the latitudinal diversity gradient. Additionally, 85% of the species are expected to expand their ranges and that
the main driver of species compositional change is nestedness. If other factors, such as habitat degradation
and overfishing, do not bring the global biomass of cephalopods down there is great potential for them to
increase their importance in global fisheries production, being a good candidate to replace endangered fish
stocks in the near future.

The Adriatic anchovy stock prediction from the winter sea conditions - possible link between the basic
science and national economic strategy

Rudjer Boškovic Institute, Center for Marine Research, Republic of Croatia
Corresponding author: [email protected] (R Kraus)
The two most commercial Adriatic species are anchovy, Engraulis encrasicolus (L.) and sardine, Sardina
pilchardus (Walb.). Our previous work indicated that anchovy catch in the Adriatic is especially large after
winters of specific circulation type in which Po River waters spread across large part of the northern Adriatic
(NA) increasing the bioproduction. Excess feeding of anchovy in the pre-spawning period (February) can lead
to increased amounts of the anchovy eggs two months later. As the anchovy reaches the commercial length of
around 9 cm in about four and a half months, the April generation might significantly contribute to the total fish
catch of the same year, which peaks in September. Despite the prevailing oligotrophication trend in the NA, the
anchovy stock and catch increased after 2000, coinciding with an increased number of the ""A"" winter type
occurrences, when Po River waters are favoured to spread across the NA. A validation of our hypothesis in a
multidisciplinary study of a larger scope with field data and modelling expertise is needed. Such efforts should
result with more efficient preservation of anchovy stock moderated by stimulation grants for anchovy fishing.
An investigation relating the sardine to oceanographic conditions should be performed as well.

Polychlorinated biphenyls (PCBs) and hexachlorobenzene (HCB) are organic contaminants present in
estuaries and adjacent coastal waters that tend to accumulate in fish. Estuaries tend to accumulate higher
quantities of organic contaminants than adjacent coastal waters, because estuaries are more exposed to high
anthropogenic activities. Platichthys flesus, a fish with high economic value, was analyzed for PCBs and HCB
along its different age groups, in four different tissues: liver, gills, gonads and muscle. Younger fishes were
caught in the estuary, whereas older fishes were caught in the adjacent coastal waters and acquired at
Figueira da Foz Regional Office of Docapesca-Portos e Lotas, SA. Younger fishes presented higher PCBs
concentrations than the older fishes. In opposition HCB was only detected in fish from 3+ to 5+ and its
concentration tended to increase with age. For both contaminants concentrations follow the pattern: liver > gills
> muscle. Hepatosomatic index had the lowest values in younger fishes and the highest values in older fishes.
Condition factor values remain stable with age. Overall P. flesus is considered safe for human intake.

Echinogammarus marinus (Leach, 1815) is a gammarid amphipod that occurs from Norway to Portugal
especially on rocky substrates covered by the brown macroalgae Fucus spp. (Maranhão et al. 2001). It is
considered a key species in the estuarine intertidal communities, playing an important role in the trophic web
energy transfers (Marques and Nogueira, 1991). Our study aimed to determine differences in population
structure, dynamics and production of E. marinus populations from three different estuaries presenting a
hypothetical gradient of environmental pressure: Minho (low-impacted), Mondego (medium-impacted) and Ave
-2
(highly-impacted). Abundances were higher in the Mondego estuary (1110.4 ind.m ) followed by Minho (482.8
-2
-2
ind.m ) while Ave presented the lowest values (329.4 ind.m ). As a supposedly low-impacted estuary we
47
expected higher density and production values in the Minho populations, however the differences found
between this and the Mondego populations might be due to overall higher copper, cadmium and PAH
concentrations in Minho (18.8 µg/g, 0.20 µg/g and 412.2 µg/g) than in Mondego (14.7 µg/g, 0.14 µg/g and
330.6 µg/g). Lower salinity values in Minho, an important environmental driver (Maranhão et al, 2001) might
have also affected density and production. Our findings suggest that the Minho estuary is not as low-impacted
as was thought and that the Mondego population is more resilient than its fellow populations from the Ave and
Minho estuaries.

Fish assemblages in transitional ecosystems are naturally adapted to stressful conditions associated with high
environmental variability. Human activities in these systems are likely to determine additional stress with a
possible effect on fish fauna, hence on fisheries. In order to test the relative importance of natural and
anthropogenic factors in determining changes in fish assemblages, catches (incl. by-catch) from artisanal
(fykenet) fisheries were monitored seasonally in different areas of the Venice lagoon (Italy) between 2001 and
2013. Changes in fish community composition and in the biomass of target species/groups were analysed and
the results were related to the variability in anthropogenic pressures. These were distinguished into
morphological, resource and territory use, and matrices quality-related pressures, with relevant variability in the
studied system being either only spatial (e.g. habitat loss) or spatial and temporal (e.g. water quality, fishing
effort). Statistical tests were carried out using a model-based analysis of multivariate data. Results highlighted
that environmental conditions (salinity and meteorological events) are more relevant than anthropogenic
pressures in explaining spatial and temporal changes in the lagoon fish assemblage. A particularly negligible
effect seemed to be associated with fishing effort, thus suggesting that the local artisanal fishery is a
sustainable activity.

The Vistula Lagoon is one of the largest lagoons in Europe. In the last decades nutrient loading changes,
warming trend and biological invasions were observed. The researches (chlorophyll, nutrients, primary
production, etc.) were carried out monthly since 1991 to 2013, which allows estimating the impact of these
processes on the lagoon. Eutrophication is one of the most important problems. Mean annual temperature
increased by 1.4°. for 40 years, and water warming combined with other factors created conditions for
3
phytoplankton “hyperblooms” (70-80 mgChl/m ) in 1995-2010. Mean annual primary production in 2000s (430

gC m year ) is considerably higher, than in the middle of 1970s (300 gC m year ). The climate warming has
caused ongoing eutrophication of the lagoon despite of significant reduction of nutrient loading in 1990-2000s.
After the invasion of the filter-feeding bivalve Rangia cuneata the benthic biomass increased by 8 times (360

g/m ), and chlorophyll decreased by 3.5 times (10 mgChl/m ) in 2011. Water quality is significantly improved
from “poor” to “satisfactory” level, e.g., transparency increased by 2 times. The phytoplankton assimilation
-1

numbers increased to maximum (300-400 mgC mgChl day ), which is unparalleled in aquatic ecosystems,
and primary production remained at previous level. Therefore, bivalve invasion improved water quality, but
lagoon ecosystem remained at hypertrophic level.

The main aim of this study was to evaluate the temporal changes in the phytoplankton community and to
identify the stressors involved. Environmental and phytoplankton data were gathered from several studies
conducted in the 60’s, 80’s and from 1999 to 2010 (2000’s). No significant changes were found between
temperature and nitrogen values in the three periods. However, chlorophyll concentrations were found to be
lower in the 2000’s. In the 80’s, diatoms were the most abundant group in the majority of samples and were
found to be associated with nitrogen concentrations (CCA), relationship not observed in the 2000’s. In the
period 2006-07, the importance of diatoms decreased and smaller cells became more abundant (e.g.
Cryptophytes, Euglenophytes, Prasinophytes). The ratio Cryptophyta/Bacillariophyta seems to yield an
increase from <1 (80’s) to >1 (2006-2007). Mesodinium rubrum and Dinophysis produce recurrent toxic blooms
in the coastal area. We can speculate the estuary can be a criptophyte producer to sustain the cryptophytesM.rubrum-Dinophysis trophic relationship. A top-down hypothesis (shellfish grazing) is considered to explain
the chlorophyll decrease. A quantitative tool, the Phytoplankton Community Index (PCI) yielded a significant
deviation of the community, from the 80’s to the 2000’s, suggesting a shift towards the dominance of small
cells.

Upwelling events in southwest coast of Portugal can trigger phytoplankton blooms which are important for the
economically important fisheries and aquaculture sectors in this region. However, climate change scenarios
forecast a decrease in the intensity and frequency of upwelling events, thereby impacting these sectors. Shifts
in the phytoplankton community for blooms were analyzed from the end of 2008 until the beginning of 2012 by
examining he bio-optical properties of the water column. The phytoplankton community was assessed both by
microscopy and chemotaxonomic methodologies, using pigment concentrations determined by HPLC. The
dynamics of diatom bloom events were also assessed with other bio-optical parameters such as absorption
coefficients for total particulate matter, non-algal and coloured dissolved organic matter. Results showed a shift
from diatom dominance related with upwelling events, to small flagellate dominance, namely prymnesiophytes,
prasinophytes and cryptophytes, in non-bloom conditions. Dinoflagellate blooms were lower than results
obtained previously. In bloom conditions, light absorption from phytoplankton increased markedly, while nonalgal particles and coloured dissolved organic matter absorption remained relatively constant. Possible impacts
on remote sensed ocean colour retrieval were also addressed. These data demonstrated some of the potential
outcomes from climate change for the area.

Living marine stromatolites occur along a 200 km stretch of South African coastline, from Cape Recife in the
east to the Storms River mouth in the west. Stromatolites date back in the fossil record at least 2.7-3.5 billion
years, thus the study of the few extant colonies remaining in the marine environment may help understand the
hydrospheric conditions that prevailed at the onset of life on Earth. Actively calcifying stromatolites on the
South African coast form rimstone dams capable of retaining freshwater seeped from the dune cordon in the
supratidal platform. Resulting pools constitute a unique ecosystem, in which drastic shifts between freshwater
and marine-dominated conditions alternate regularly in response to vertical mixing and the balance of dune
seepage versus marine inflow. N-nutrients appear to be supplied mainly via the dune seeps. The epibenthic
algal community within stromatolite pools is generally co-dominated by cyanobacteria and chlorophytes, with
minimal diatom contribution. A rich macrofauna thrives within the stromatolite pools, apparently negating the
classic view that the demise of stromatolites observed since the early Paleozoic is due to metazoan radiation.

Threats to these systems are currently posed by eutrophication from residential developments and sea level

In estuaries and shallow coastal zones, up to 50% of the ecosystem-level primary productivity is due to
microphytobenthos (MPB), the diatom-dominated benthic communities that form dense biofilms on soft
sediment intertidal flats. MPB exhibit high photosynthetic performances despite the stressful environmental
conditions experienced during emersion. This phenomenon relies on complementary physiological and
behavioural (vertical migration within the photic zone) processes which remained to be consistently
characterized at the community level, especially on intact biofilms. Breakthroughs in our understanding of
these processes were achieved by developing an innovative methodological approach which combines
advanced imaging techniques, a new device for surface sediment micro-sampling, chemical inhibitors and
biochemical analyses targeting the different processes. Several comparative studies were carried out at
different seasons along the Atlantic coast (Tagus estuary and Ria de Aveiro in Portugal, Baie de l’Aiguillon in
France). Our results show a high photoprotective capacity with photoinhibition rates remaining below 25%. The
relative contribution of the studied mechanisms (e.g. vertical migration, xanthophyll cycle activity, protein D1
turnover) to overall photoprotection varied according to season and geographic origin of the communities. Our
results emphasize the combined role of temperature and high light in limiting the photosynthetic activity of MPB
biofilm in situ.

Effect of the ocean acidification (OA) on the composition of coastal phytoplankton population was
experimentally examined. Ambient (ca. 400 .atm), 800 and 1200 .atm conditions were treated with the mixing
of 3% CO2 and ambient air. After addition of the nutrients (Day 1), changes in the concentrations of

liquid chromatography (HPLC) and flow cytometry (FCM). A small compositional change among the treatments
was noticed during the bloom stage. In the latter period of the experiments, increase in the concentrations of
chlorophyll b and peridinin were noticed in the most acidified condition with concomitant decrease in 19’hexanoyloxyfucozanthin. On Day 29, the contribution of cell number of the picoplankton was much higher
(73%) in the 1200 .atm vessels than the ambient condition (21%). Pigment composition, microscopic
observation and FCM analysis strongly suggest that Micromonas spp. actively grew in the most acidified
vessels. It is possible that phytoplankton population shifts into the smaller size under higher CO2 and lower pH
condition. The structure of food web and the biogeochemical properties such as efficiency of biological pump
will be changed by OA through the compositional change in phytoplankton.

The identification of the effects of natural and human pressures on the performance of indices used to assess
the ecological quality status of aquatic ecosystems is essential to understand the response of univariate and
multimetric indices to any disturbance and the consequences for the ecosystem quality classification. This
study focused on the variability of univariate and multimetric indices using data on macrofauna collected in the
Mira River estuary (SW Portugal) over a period of 26 years (1984-2010) and its association to water and
sediment physicochemical parameters, hydrology and climate data. Results showed a decrease on the number
of species identified as sensitive to organic pollution, mainly marine amphipods and bivalves. An increase on
tolerant species was also registered, which seems to be related to an increase on local human pressures in
recent years. Biotic indices reflected especially the increment of organic matter input due to urban sprawl.
Diversity and richness showed a decreasing trend over the studied period despite some high values over time.
These results indicate that ecological status assessment is influenced both by natural variability and human
pressures, requiring a long-term background data set to support the interpretation of changes on the metrics
used.

Human activities at sea are still increasing. As biodiversity is a central topic in the management of our seas, it
is important to understand how diversity responds to different disturbances related with physical impacts. We
investigated the effects of three impacts, i.e. sand extraction, dredge disposal and offshore wind energy
exploitation, on the soft-bottom macrobenthic assemblages in the Belgian part of the North Sea. We found
similar diversity-disturbance responses, mainly related to the fact that different impacts caused similar
environmental changes. We observed a sediment refinement which triggered a shift towards a young, dynamic
(transitional) soft-bottom macrobenthic assemblage, with several species typically associated with fine
sediments. This led to a local unexpected biodiversity increase in the impacted area. On a wider regional
scale, the ever increasing human impacts might lead to a homogenization of the sediment, resulting in a more
uniform, yet less diverse benthic ecosystem.

The effects of mercury contamination on the population structure and dynamics of the gastropod Peringia
ulvae and its impacts on the trophic web were assessed along a mercury gradient in Ria de Aveiro (Portugal).
The gastropod was revealed to be a tolerant species to the contaminant, since the highest densities,
biomasses and growth productivity values were recorded at the intermediate contaminated area followed by
the most contaminated one and finally the least contaminated area. P. ulvae was however negatively affected
by mercury in terms of growth and life span. So, in the most contaminated are the population was
characterised mainly by the presence of juveniles and youn individuals. The intermediate contaminated area
showed a greater equilibrium in terms of groups' proportion, being the adults the dominant set. The least
contaminated area presented intermediate values. P. ulvae life spans were shortest in the most contaminated
area (7-8mo), followed by the least contaminated area (10-11mo) and finally, the intermediate one (11-14mo).
P. ulvae revealed to be an important vehicle of mercury transfer from sediments to the trophic web,

This paper studies dynamics of littoral communities, trophic webs interactions and shifts in structure of
biocenosis under eutrophication phenomena in the Neva Estuary, the largest estuary and one of the most
eutrophic parts in the Baltic Sea. High nutrient inputs to the Neva estuary result in macroalgal blooms in the
littoral zone initiated by opportunistic filamentous algae. The great masses of drifting algae or loose-lying mats
result in deoxygenation of underlying near-bottom areas during algae decomposition. The hypoxia influences
strongly on bottom environments facilitating decrease in species richness and abundance and structural shifts
of the benthic community. The community in the stressed habitats consists of eurybiotic taxa (chironomids,
annelids and recent invasive amphipods and molluscs). The invasive amphipods and other opportunistic
species are able to be tolerant to the threats caused by the algae decomposition over prolonged periods until
they eventually migrate to areas with more favorable conditions. This behavioral adaptation can be considered
as a mechanism facilitating these taxa dominance in the shallow Baltic eutrophic areas. The assessment of the
role of such species in the food web dynamics was performed, and the possible impact on different food chains
as a result of euryphages (with varying percentage of plant and animal food in a diet) was evaluated.

Mercury bioaccumulation and depuration kinetics were assessed in the glass eel Anguilla anguilla following
exposure via seawater. Overall, glass eels under Hg exposure exhibited a significant increase in contaminant
level compared with control ones, revealing great accumulation capability. Distinct bioaccumulation kinetics
-1
were observed depending on the exposure concentrations. For low Hg levels (1.5 µg L ), accumulation tended
to follow a saturation model, reaching an apparent steady state after 15 days of exposure. For high Hg levels
-1
(50 µg L ), glass eels exhibited a linear model of accumulation. Bioconcentration factors revealed that
bioaccumulation was not proportional to the different Hg concentrations. Regarding the depuration phase,
juveniles of A. anguilla demonstrated slight Hg losses after 3 days in clean seawater (2% and 10% for low and
high Hg treatments, respectively). At the end of the depuration period, levels of Hg lost did not vary significantly
from those observed at day 15 of the exposure phase, meaning that glass eels were not able to eliminate Hg
and to reach the original condition. Most important, individuals exposed to higher contamination still retained
Hg levels (> 1.0 ppm) exceeding those allowed by the European legislation regulating human food
consumption, which raises serious public health concerns.

Tagus estuary bottom sediments are known to have a wide range of heavy metal concentrations depending on
sediment type and geographical position within the estuary. Both margins of the Tagus estuary are highly
affected by anthropogenic pressures, with the north margin more densely populated and the south margin
historically characterized by a strong industrial presence thus leading to different degrees of metal
contamination. In the last decades with the introduction of several European directives, an urgent need arose
for the development of efficient biological tools for ecological quality assessment. Several biological elements
were established as potential good indicators for this propose, and among these benthic macroinvertebrates
are one of the most used for establishing the ecological quality status of a water body. These communities
inhabit the bottom sediments, thus being subjected to different degrees of contamination. In the present work,
the potential use of these communities will be discussed while evaluating the metal contamination of estuarine
bottom sediments, as well as the potential use of their ecological variables as predictive tools within the
ecological quality assessment programs, like the Water Framework Directive (WFD) and the Marine Strategy
Framework Directive (MSFD).

The aim of this study was to test how a variety of different types of indices (indices based on: species diversitySD, functional diversity-FD, and a combination of SD and FD) performed in regards to the different disturbance
conditions within the lower Mondego estuary, Portugal. As biological descriptors we used biomass data from
soft-bottom invertebrate species from 4 subtidal sites situated within the lower estuary. 2 sites within the more
'heavily' physically disturbed North arm of the estuary and 2 sites within the 'less' physically disturbed South
arm. A total amount of 10 indices were tested: species richness (SR), Simpson diversity (SimD), dominant
traits- (mT-values), functional richness (FRic), functional evenness (FEve), functional divergence (FDiv),
functional dispersion (FDis), Rao's Quadratic Entropy (FRao), functional redundancy (FRed) and a new
introduced SR-FRed index. The indices that performed better were: SR, mT-values, FRic, FRed and SR-FRed.
These indices were able to indicate differences in physical disturbance and other types of disturbances. The
indices that performed less were: SimD, FEve, FDiv, FDis and FRao. All of these indices are weighted by
abundance, and gave a differential weight to the traits of the more dominant species. Overall, most indices
gave complementary information regarding the functioning of the benthic communities within the lower estuary,
and for this reason we recommend that any study investigating functioning should employ several
complementary indices that are based on SD, FD and a combination of SD and FD.

Benthic nematodes are widely regarded as very suitable organisms to monitor potential ecological effects of
natural and anthropogenic disturbances in aquatic ecosystems. During 2008, the stable seagrass beds of
Zostera noltii located in Mira estuary (SW Portugal) disappeared completely. However, during 2009, slight
symptoms of natural recovery were observed, a process which has since evolved intermittently. This seagrass
beds have a rare database available in Portugal sampled before the disturbance based on temporal and
spatial biodiversity patterns nematodes assemblages. The main goal is to investigate the responses of
nematode assemblages to Zostera collapse, based on both communities before and during the early natural
habitat recovery. We hypothesized that collapse would induce a decrease in abundance and both structural
and functional diversity of the nematode assemblages. A PERMANOVA analysis with the 3 factors: “Before”
and “After” collapse; 2 sampling “Sites” (A and B); 4 “Sampling Occasions” confirms the existence of significant
differences (p<0,05) in abundance and diversity (d, H’), although no significant differences was obtained based
on trophic composition and ITD (Index trophic) and MI (Maturity Index). The nematodes community response
following this extreme event exhibited considerable resistance and resilience allowing demonstrate a natural
adjustment to the new conditions.

Several works have evidenced in the past the importance and influence of plants and terrestrial invertebrates
in metal availability in soils and sediments through changes in metal speciation. In contrast, the impact of
estuarine invertebrates and fishes in metal speciation has been poorly explored. The partition of metals in
53
estuarine surface sediments, according to four operationally defined fractions, was studied in a controlled
environment. Sediments were analyzed before and after the passage through the gut of a filter feeder and a
detritivorous species. Scrobicularia plana (Bivalvia: Semelidae) is a widely distributed species in the NE
Atlantic estuaries, living buried at about 5 to 20 cm deep, and feeding on the bottom and suspended sediment
particles through the inhalant siphon. Liza ramada (Actinopterygii: Mugilidae) is a catadromous fish with a wide
distribution. It is an interface feeder, filtering the superficial layer of the sediment and particles in the water
column, being essentially a primary consumer with a great feeding plasticity. The outcome of the controlled
experiments pointed to a potential increase in some metals’ availability in the estuarine environment, as a
result of the more mobile metal forms in the excreted fecal pellets.

Intensive fishing occurs in the marine zone of the natural park “Parque Natural do Sudoeste Alentejano e
Costa Vicentina” (PNSACV; SW coast of continental Portugal). In this zone, fishing regulations are in place
since 2006 and marine protected areas (MPAs) were designated in 2011. Direct and indirect effects of this
protection were assessed in 2011, 2012 and 2013. Visual censuses of abundance and size were performed in
intertidal and subtidal macrobenthic populations and assemblages of rocky habitats. Studied populations
include shellfish species targeted by fisheries: limpets, topshells, sea urchins, crabs and octopuses at intertidal
and/or subtidal levels. Studied assemblages include cryptic and non-cryptic fishes, echinoderms and sessile
seaweed and invertebrates (intertidal and/or 10 m deep). The northern half of PNSACV was sampled at a
scale of tens (site) and hundreds (area) of meters. Two MPAs (“Ilha do Pessegueiro”, “Cabo Sardão”) and six
control areas were sampled. Using univariate and multivariate analyses, no significant effects of protection
were found in most cases, possibly because conservation measures are still recent. Significant differences
were found among sites or areas in most cases. Replication in time, within a monitoring programme, is
recommended to assess the ecological effects of these measures.

Several abiotic and biotic factors are known to influence the settlement and recruitment of marine organisms.
However, our understanding of the factors driving colonisation in marine man-made structures is lacking.
Shading and sedimentation are two important factors associated with human activities that may affect the early
colonization of fouling organisms. We assessed the effects of sedimentation and shading on the recruitment of
fouling organisms with a manipulative field experiment. PVC-recruitment plates (10 x 10 cm) were subjected to
a factorial block experimental design. Shading was achieved by installing a larger opaque PVC plate over the
recruitment panel. A standardised sediment solution was added every 5-7 days to ‘with-sediment panels’ until
the experiment was finished. Linear mixed modeling was used to determine differences between treatment
levels and the interaction between factors on recruitment of invertebrates and algae. Sediment deposition
negatively affected species diversity, while shading reduced the abundance of algae cover. Our results
suggest that both factor play an important role in driving the early colonization of fouling organisms, however
further studies are necessaries to understand their role during the community succession.

From genes to ecosystems: effects of global change
Volckaert FAM
Laboratory of Biodiversity and Evolutionary genomics, Department of Biology, University of Leuven, Leuven, Belgium
[email protected]
The impacts of global change, pervasive and threatening all levels of biodiversity, are increasingly obvious in
marine populations. Human intervention is shaping measurably the evolutionary processes of adaptation, gene
flow, mutation and genetic drift, sometimes in very short time periods. Enhanced selection pressures have
modified life history traits, as exemplified in fisheries induced evolution. Selection pressures from cocktails of
pollutants, eutrophication and acidification have influenced metabolic and behavioural traits. Shifting patterns
of climate variability reduce effective population size, such as observed in some clupeids. Altered gene flow,
especially in coastal settings, has restructured populations. For example, wild Atlantic salmon populations
across their range hybridise with vast groups of escapees and acquire new traits. Some populations have
shrunk so much, either due to habitat loss, overexploitation or recruitment failure, that genetic drift takes over.
Especially estuarine populations suffer from such population collapses. The measures necessary to curb these
unprecedented pressures are diverse, needed and feasible.

In managing any estuarine or marine area, global climate change is regarded as an exogenic unmanaged
pressure in which the local management has to respond to the consequences of that change rather than the
causes of the change. In tackling those consequences and carrying out a risk assessment for any individual
effect or for cumulative effects, it is valuable to summarise our current understanding as a set of conceptual
models (as ‘horrendograms’). These, firstly, then can inform the direction of our future research in both the
natural and social sciences (i.e. indicating what we know and what we do not know). Secondly, the conceptual
models allow us to present managers with the sequence of responses by the natural and human systems, and
hence inform management actions and the implementation of legislation such as European Directives. This
contribution presents a set of 8 inter-linked conceptual models which summarise the consequences of global
climate change according to 8 main topics and across the biological system from the individual to the
ecosystem. These are: (I) Altered temperature regime – species re-distribution; (II) Altered temperature regime
– physiological repercussions; (III) Physiographic changes – increased relative sea-level rise; (IV) Coastal
hydrodynamics – increased climate variability; (V) Land-based discharges and run-off – changes to
NAO/rainfall run-off patterns; (VI) Estuarine hydrodynamics – increased relative sea-level rise; (VII) Seawater
physico-chemical changes – ocean acidification, and (VIII) Global transport repercussions – loss of polar ice
cover. This assessment shows both the likely changes experienced by the seas and estuaries and their ability
to cope with those changes.

Estuarine biodiversity will experience important changes with the rise in the mean sea level and global oceanic
warming. Species populations of narrow-range niche, with limited dispersal potential, and with fragmented
habitat by historical urbanisation, would be at local extinction risk under climate change. Here we present an
overview of our research line aiming to assess: 1) main climate projections in the estuaries (sea level rise and
sea warming) throughout the 21st century, 2) impacts in species habitat suitability (e.g. Zostera noltii), using
ecological niche models, both at local (Basque estuaries, Spain) and European level, and 3) vulnerability of
species and communities (saltmarshes, seagrasses, soft-bottom macroinvertebrates) using molecular markers
and community analysis, based on connectivity proxies. Our findings indicate that species habitat suitability will
shift poleward (890 km) due to sea warming and shift landward to inner estuaries due to sea level rise, with
squeezing consequences. This has implications to saltmarsh plants and seagrass beds since both community
55
and genetic analysis indicate they are dispersal limited. Z. noltii populations might not shift their suitable habitat
northward at a pace comparable to warming rates. In contrast, soft-bottom macroinvertebrates were spatially
unstructured suggesting they have high resilience capacity to moderate changes.

We explored the molecular and physiological responses, life history traits and genetic structure of flounder
(Platichthys flesus) populations located in estuaries with contrasted conditions, from the English Channel to the
Portuguese Coast. The Mondego population (Portugal) corresponds to the southern limit of flounder
distribution area and it was compared to northern core populations. Marked phenotypic differences were
detected which suggested that flounder populations’ response to the southward increase in water temperature
was via reduced tissues’ mitochondrial density associated with increased mitochondrial ATP synthesis
capacity. A Common Garden experiment involving three populations (Mondego, Vilaine, Seine) suggested that
compared to the northern populations, the peripheral Mondego population displayed reduced capacity to face
hypoxia and combined thermal and chemical stresses. Overall this study suggested that the local adaptation of
the Mondego population to its harsh thermal environment could be associated with higher metabolic cost,
lesser ability for physiological multitasking and thus higher vulnerability to multiple environmental stressors.

Corresponding author: [email protected] (M Tagliarolo)
Mussels are critical intertidal ecosystem engineers, creating habitat for many species. The two dominant
mussels in South Africa are the indigenous Perna perna and the invasive Mytilus galloprovincialis. These
species have similar life styles and resource requirements but different distribution patterns. Mytilus dominates
the cool temperate west and Perna the subtropical east coast. Perna is absent from the west coast, but coexists and competes with Mytilus on the warm temperate south coast. Moreover, two genetic lineages of
Perna exist in South Africa and overlap on the south-east coast. The thermal tolerances of marine ectotherms
are strongly related to environmental temperatures and can be important in explaining species distributions.
We investigated the effects of acute temperature change on heart rate, oxygen consumption and anaerobic
end product production for Mytilus and both Perna lineages under immersed and emersed conditions in the
laboratory. During emersion, heart rate and oxygen consumption were significantly reduced and not correlated
with temperature for all three classes. During immersion, temperature had powerful and similar effects on
metabolic rate, but the ranking of heart rates reversed between heat and cold stress. The western Perna
lineage appeared better adapted to rising temperatures, while Mytilus showed higher heart rates during
cooling.

In future model scenarios (IPCC) marine organisms will deal with increasing temperatures and pCO 2 and many
of the biological consequences are still unknown. As many of these organisms form the primary production of
oceans, any change in their life cycle may potentially impact all marine ecosystems. The present study
56
evaluated the oxidative stress responses of Sparus aurata exposed to increasing water temperature and
different pCO2. Thus, fish were distributed in tanks by two different temperatures (18º and 22ºC) and pH (7.5
and 8.0). Following 42 days of exposure fish were euthanized by cervical transection and the selected organs
removed and stored at -80ºC until further analysis. Sub-samples were taken and processed for histological
analysis. Stored samples were analysed for heat stress proteins (HSP70) and stress oxidative enzymes (SOD,
CAT, GST) and lipoperoxidation. The results show variations in HSP70 and stress oxidative enzimes according
to the exposure parameters also supported by the histological observations. The results suggest that sea
warming and sea acidity are important stressors that will affect fish physiology, thus compelling the need to
perform these type of studies to enhance the predictive and environmental management capacities and
produce valuable data for scientific community and decision makers.

In many parts of the world, the intensification of poleward boundary currents is causing localised warming and
the extension of tropical biota into temperate systems. In eastern Australia, rising temperatures in the last 60
years have been linked to an increase in the abundance of tropical species in temperate systems. Here, we
present evidence that this long-term temperature increase has also coincided with a decrease in kelp forests
near the warm-edge of their distribution. Making use of long-term video data originally collected to monitor fish
populations, we show that the dominant kelp Ecklonia radiata has completely disappeared from various sites at
the Solitary Islands Marine Park (SIMP), a tropical-temperate transition zone. Video images from years prior to
the complete disappearance of kelp show clear and abundant herbivore bite marks on remaining kelps,
suggesting an important role of herbivory in mediating this decline. We experimentally tested the role of
herbivory in determining the kelp distribution at SIMP using filmed kelp transplants and found that herbivory
was more intense on coral-dominated reefs compared to the nearest kelp-dominated reefs. We propose that
higher rates of herbivory by invading and functionally diverse tropical herbivores extending their ranges into
temperate regions may be a mechanism facilitating transitions from kelp to coral dominated reefs in eastern
Australia.

Extreme temperature events occur more frequently nowadays, as an implication of global climate imbalances.
Although these "heat waves" and "cold waves" last for only a few days, they put the plasticity of the
ecosystems to test as well as their resilience. Halophytes are no exception to this. Being highly adapted to
harsh environments these species present efficient counteracting mechanisms in order to overcome the
energetic imbalance resultant from sudden changes in the surrounding thermal environment. During extreme
thermal events the primary productivity of these species is drastically affected. Most species exhibit a
significant decrease in their primary photochemistry mechanisms alongside with evident energy dissipation and
thus a decrease in their biomass productivity. These response mechanisms are evidence of an adaptive
evolution of the halophytes while colonizers of extreme environments. In the present work the impact of shortterm extreme temperature waves on halophyte ecophysiology will be addressed from its gene expression, to
photochemical, bioenergetic and biochemical mechanisms to obtain a comprehensive picture of the adaptation
capacity and the implications of halophytes on the ecosystem services.

Microphytobenthos (MPB) are often the main primary producers of intertidal and shallow subtidal estuarine
environments, which are among the ecosystems most sensitive to climate change effects. In this work, the
interactive effects of elevated temperature and CO2 on intertidal MPB biomass, photosynthetic performance
and species composition were studied using a flow-through non-recirculated experimental live support system.
A decline in MPB biomass (NDVI and Chlorophyll a) and photosynthetic efficiencies (Fv/Fm and a) was
observed under higher temperature (24ºC). At lower temperature (18ºC), there was a positive effect of
increased CO2 availability (pH 7.4) on MPB biomass, but photosynthetic parameters were similar to control
conditions (pH 8.0). Although the MPB community was in all cases dominated by diatoms, there was an
increase in the relative abundance of cyanophytes under higher temperature. A CLUSTER analysis of the
diatom assemblage also revealed that there were significant differences between the two temperatures but not
between pH treatments. We conclude that there was a detrimental effect of increased temperature on MPB
biomass and photosynthetic performance, with a concomitant change in the MPB community assemblages.
These effects were not counterbalanced by increased CO2, which only had a beneficial effect on MPB biomass
under lower temperature.

Connectivity between ecosystems is of high ecological relevance, especially when adjacent areas of
contrasting productivity are compared. This is the case of high productive rocky bed habitats dominated by
macroalgae, which are one of the most important allochthonous sources of marine wrack subsidies linked to
low productive ocean sandy beaches. Rocky bed communities are known to be affected by global climate
change variables. To check for deleterious effects of UVR and temperature, we mimicked a rocky intertidal
ecosystem by building a set of mesocosm tanks harbouring two main macroalgal species, Laminaria
ochroleuca and Sargassum muticum, subjected to a combination of radiation and temperature treatments. The
two macroalgal species displayed differential and variable responses to UVR and temperature manipulations.
We further used the treated macroalgae to explore the effects of global change on the feeding behaviour of the
common beach amphipod Talitrus saltator. We suggest that the effects of climate change variables on
macroalgae might shift source-sink dynamics between highly connected ecosystems as the rocky intertidal and
sandy beaches. Understanding the way in which change variables interact and influence allochthonous
subsidies in recipient ecosystems is of paramount relevance to assess accurately the consequences of global
climate change and its proper management.

Corals are under siege by local and global stressors, which lead to loss of diversity, seascape complexity and
services. Loss of coral is very often associated with shifts from coral to algae dominance. Seaweeds are
recurrently suggested to play an important role in coral degradation, but studies are almost completely biased
toward tropical systems. In this study we investigated seaweed-coral interaction using three temperate
gorgonians (Eunicella verrucosa, E. gazelle and Leptogorgia sarmentosa) and one of the most invasive
seaweeds Asparagopsis armata. Surveys showed that rhodophyte seaweeds form the most dominant
gorgonian epibionts. The most dominant benthic herbivore in the system has a low feeding preference for A.
armata and as such does not exert a top-down control. Using denaturating gradient gel electrophoresis
(DGGE) we detected that gorgonians in direct contact with A. armata had shifted microbial community
compositions. Activity of the microbial community of the gorgonian mucus layer and tissue degradation
increased with direct contact and in close proximity of A. armata in aquarium experiments. Our study suggests
in temperate waters a strong interaction between Rhodophyta and gorgonians and an importance of the coral
holobiont in its interaction with seaweeds just as is suggested on coral reefs.

Increases in ultraviolet radiation and CO2 affect phytoplankton growth and mortality in an array of different
ways. However, in situ responses of natural phytoplankton communities to climate change, as well as its
effects on phytoplankton annual cycles, are still largely unknown. Although temperature and UVR have been
increasing in temperate latitudes during winter, this season is still particularly neglected in climate change
studies. Additionally, coastal lagoons are highly productive ecosystems and very vulnerable to climate change.
This study aims, therefore, to evaluate the short-term effects of increased UVR and CO2 on winter
phytoplankton assemblages in Ria Formosa. We used microcosms to evaluate the isolated and combined
effects of UVR and CO2, under ambient and high CO2 treatments, exposed to ambient UV levels and PAR, or
to PAR only. Phytoplankton composition, abundance, biomass, and photosynthetic parameters were
evaluated. Significant changes were observed in the growth of specific phytoplankton groups, leading to
changes in community composition. The cyanobacterium Synechococcus was dominant in the beginning of the
experiment, but it was negatively affected by UVR and CO2. Diatoms benefited from high CO2 and UVR,
particularly Thalassiosira. Despite the changes observed on specific phytoplankton groups, growth and
production of the whole phytoplankton community did not show significant responses to UVR and/or CO2.

The combined effect of ocean acidification and global warming is known to be deleterious for several marine
photosynthetic invertebrates, including corals and foraminifera. However, the physiological responses of noncalcifying photosynthetic organisms remain unclear. In this study we evaluated the impact of environmental
hypercapnia (pH = 0.5 units) and warming (+4°C), expected by the end of this century, on the intertidal
kleptoplastic sea slug Elysia viridis. Although being equipped with physiological mechanisms against the
environmental stress, our results demostrated that E. viridis is vulnerable to ocean acidification and warming.
More specifically, survival and growth were negatively impacted by these climate change–related variables, but
not fertility. Moreover, the ability to up-regulate anti-oxidants and reduce the accumulation of reactive oxygen
species suggests a resilient behaviour under exposure of stressful conditions. Bleaching was not observed,
and the maximum quantum yield of kleptoplast photosystem II (Fv/Fm) was preserved, which seems to
indicate that the photosymbiosis is not affected by the future environmental conditions.

Bivalve histopathology has become an important tool in marine toxicology, although not yet as detailed and
standardized, with respect to pathology identification and terminology, as in fish. However, besides the specific
aetiology of environmental pollution to wild organisms, there are many gaps on the interference of potential
site–and species–specific confounding factors. The present work aimed at developing a detailed semi–
quantitative histopathological assessment in two organs (digestive gland and gonads) of mussels (Mytilus
galloprovincialis) collected from five sites with different pollution profiles in the Basque Coast (N Spain), during
the four seasons of a full year. A total of twenty-three histopathological alterations were analysed in the two
target organs. Based on comparisons with reference animals, the results indicated that mussels from the most
59
industrialized harbours endured the most significant deleterious effects. Neoplastic diseases were scarce, with
only a few cases of benign neoplasms (and a single case of malignancy) being recorded. On their turn,
seasonality, presumably temperature–related and increased levels of background infections were liable to
positively modulate histopathological indices, thus masking true toxicopathological effects. Overall, the
digestive gland yielded more conclusive histopathological findings than gonads, permitting clearer cause–effect
relationships with environmental parameters.

Temperature is one of the most important variables influencing organisms, especially in the intertidal zone.
Current concerns about climate change emphasize the need to study physiological and molecular mechanisms
of response and/or adaptation to high temperature and ocean acidification. In this context, this work aimed to
test biochemical and proteomic responses of field collected shrimp Palaemon elegans exposed to high
temperature in natural conditions. The collection of the organisms was performed in April (temperatures of
approximately 18-20ºC) and June (temperatures of approximately 28-30ºC). Several thermal stress and
oxidative stress biomarkers were quantified in the muscle and visceral mass of P. elegans (Hsp70, ubiquitin,
catalase, superoxide dismutase, glutathione-S-transferase, lipid peroxidation). Following, a 2D electrophoresis
was carried out with muscle samples to detect differentially expressed proteins (using the software Progenesis
Same Spots) between control and thermally challenged organisms. The proteins were then excised from the
gels and identified via MALDI (matrix assisted laser desorption/ionization). Results showed that several
thermal stress and oxidative stress biomarkers change in the muscle and visceral mass of P. elegans collected
in June. Proteomic analysis showed 25 differentially expressed proteins (of which 21 were over-expressed and
4 were sub-expressed, when comparing the control versus thermal stressed group).

Fatty acid (FA) composition of Cerastoderma edule and Scrobicularia plana under a range of salinity
concentrations was investigated. Species were sampled in Mondego estuary (Portugal). A group of organisms
(“field”) were stored for FA analysis, whereas other organisms (“lab”) were exposed to a range of salinity
concentrations. Organisms were fed daily. Muscle was used for FA analysis. Results revealed differences in
the FA profiles of both groups, with “lab” not presenting saturated FA of short chain. The diversity on FA and
the quantity in insaturated FA at different salinity concentrations is highest at extreme salinity concentrations
(C. edule: 10 and 35 psu; S. plana: 5 and 35 psu). C. edule and S. plana “field” present the highest diversity
and quantity in polyunsaturated fatty acids (95.77%) and highly insaturated fatty acids (20.93%), respectively.
Results suggest that, under salinity stress, the consumption of food decreases and so quantity in FA, still
species are able to store FA recognized as of high physiological importance for animals, by reducing their
activity and having lower energy consumption. Therefore, it can be predicted that, at an extreme weather event
(e.g. drought or flood) these species present higher amounts of essential FA and, thus, higher food quality.

Organic compounds not directly involved in the normal growth, development and reproduction of organism are
called secondary metabolites. Biologically active metabolites could increase or reduce growth of other
organisms, or trigger different physiological responses in target cells, which could lead even to death. This
60
natural, worldwide occuring process is known as allelopathy. The studies about bioactive metabolites and
allelopathy are important in connection with their potential influence on aquatic ecosystems and practical
application in different branches of industry. The main goal of this work was to investigate the influence of
metabolites obtained from selected Baltic cyanobacteria, diatoms and dinoflagellates monocultures on growth
of green algae Chlorella vulgaris. Monocultures were cultivated in flasks to obtain the extracellular secretion.
Cell-free solutions, collected by filtering through the glass-fiber and membrane filters, were added to batch
cultures with target species. Response of C. vulgaris was described by cell counts, chlorophyll a and
pheophytin concentration and viability measurements. In this work extracellular compounds obtained from
selected Baltic cyanobacteria and microalgae monocultures demonstrated allelophatic effects towards green
algae C. vulgaris.

Three dioecious Fucus species are commonly found along the shores of the Baltic Sea. A set of morphological
characters were measured with the aim of determining if sexual dimorphism occur in the recently described
endemic Fucus radicans Bergström & Kautsky, in the Baltic Sea. Five mature receptacles were cut off each
individual and measured. For comparison, female and male receptacles were also collected from the other two
dioecious species, F. vesiculosus and F. serratus. The analysis shows that male F. radicans receptacles are
significantly smaller and have a significantly higher DW/FW ratio than the female receptacles, but with a similar
number of conceptacles per receptacle. The differences might be explained by the significantly higher tissue
density in male conceptacles compared to females resulting in an overall denser tissue with lower water
content. The reproductive effort, calculated as total DW of receptacles and receptacle carrying branches
divided by total biomass DW, was higher for males than females. Females did have a broader frond width.
Males were shown to have a higher percentage of reproductive tips (28% compared to 13%). Our study shows
several characteristics in F. radicans that support a sexual dimorphism, something that has previously not
been documented in fucoids.

Main results of the project PHYTOBIO (Phytoremediation and bioremediation of contaminants in salt marshes:
plant – microorganisms interactions) will be presented. This project investigated the potential plantmicroorganisms associations that could, on one hand, improve metal phytoremediation capacities of the plant
and, on the other hand, improve bioremediation of organic compounds, namely petroleum hydrocarbons, by
microorganisms in estuarine salt marshes. For that, autochthonous microorganisms with capacity to resist to
chosen contaminants were selected using enrichment cultures, and used in microcosm experiments.
Experiments were carried out in greenhouses with an automatic irrigation system that simulated estuarine tidal
cycles. Overall results point that, the addition of autochthonous microorganisms resistant to metals seems to
be a valuable strategy to potentiate the ability of salt marsh plants to phytoremediate these contaminants in
salt marshes, being useful for the recovery of moderately impacted estuaries. In addition, salt marsh plants and
their associated microorganisms presented a potential for bioremediation of petroleum hydrocarbons in
contaminated salt marsh sediments, although the nutritional requirements of the different plants should be
accounted for when designing cleanup strategies. Therefore, this project provided an important contribution to
the development of new strategies for the control and reduction of estuarine pollution.

Connectivity and its implications towards conservation and management
Geffen AJ
Department of Biology, University of Bergen, Bergen, Norway
[email protected]
Connectivity is a term used widely in ecology, conservation, and resource management – in terrestrial and
aquatic ecosystems. Although the same word is used in many different contexts its meaning can be very
different, and this is a particularly challenging situation for communication between scientists, managers, and
policy makers. Whereas terrestrial ecologists focus on connectivity as an attribute of the landscape or physical
system, marine ecologists have focussed on connectivity as an attribute of populations. A long range dispersal
stage is nearly ubiquitous in marine organisms and the delivery systems that link the various life history stages,
or various component populations, are large-scale features of the climate and ocean system. Anthropogenic
activities are the major disruptors of “life history closure”, as seen in classic examples where spawning
migrations are cut off by construction projects. Spatial management decisions which seek to protect specific
locations and habitats often claim to rely on science-based evidence of connectivity to justify the importance of
a specific area for a commercially important (fish) population. The spatial and biological concepts of
connectivity must be reconciled in the management of physical and biological resources, in order to meet the
challenges of shifting population distributions predicted as a consequence of ocean warming and climate
change.

Understanding the potential of marine protected areas (MPA) to sustain local populations versus the
dependence on larval supply from external areas is essential for their design and management. However,
studies directly estimating fish larval retention and dispersal are rare for temperate reef systems. Here, we
used an assignment test based on microsatellite markers to identify the natal origin of juvenile shore clingfish
Lepadogaster lepadogaster, that have successfully recruited to the Arrábida Marine Park (Portugal) in two
consecutive years. We predicted local recruitment because larvae of this intertidal rocky reef species spend
only 11-18 days in the pelagic stage and occur close to shore and near the reef. The results rejected this
hypothesis. Adult subpopulations separated by 70 km of sandy coastline north and south of the park displayed
no genetic differentiation, revealing one connected population. Furthermore, 8 and 15% of recruits originated
from populations outside the studied area in 2011 and 2012 respectively, showing an unexpected large
dispersal range of this species. The genetic structure of the adult population within the park was significantly
different between sampling years, revealing a high short-term temporal variability of the adult gene pool. This
large input of recruits from outside reserve areas and the strong temporal variability request for a study with
larger spatial and temporal scales. In conclusion, our results indicate that along temperate dynamic coastlines
only a design of several inter-connected protected areas can more effectively sustain populations with such
connectivity patterns.

Many marine species depend on estuarine environments, and connectivity between ocean and estuarine
habitats is thus a critical feature in fish ontogeny. The present study investigates the connectivity between
ocean and Lima estuary between planktonic larval stages of fishes. During spring 2009, a combined ocean
estuarine survey was conducted along the entire salinity gradient of the estuary and in two transects off the
adjacent coastal zone until reaching the 100m isobaths. Ichthyoplankton collections were performed with
plankton nets, jointly with CTD measurements, chlorophyll a, nutrients, particulate matter, and total carbon
concentrations. Water mass characteristics varied between the estuary and ocean, while ichthyoplankton
abundance and diversity increased continuously along the estuarine ocean gradient. Lima estuary comprised
16 taxa, compared to 54 taxa identified in the ocean; fish larvae belonging to three guilds, i.e, estuarine,
marine migrants and stragglers were observed. Flounder and sardines, top abundant marine migrant taxa
found in the ocean were also the most abundant taxa in Lima assemblages, highlighting the importance of
Lima as essential fish habitat. Spatial distribution of estuarine dependent species and relations with
environmental drivers along the estuarine ocean gradient are discussed in the light of nursery location and
connectivity between the Lima nursery habitats and the marine spawning grounds.

Population genetic studies provide valuable support in understanding the population dynamics of exploited
species. The New Zealand scallop (Pecten novaezelandiae) is a highly valued endemic species but despite the
strong commercial interest and overfished status of some stocks of this scallop, there is currently no
information on the population genetic structure. Genetic studies can be useful for assessing levels of genetic
variability and identifying stocks based on the degree of differentiation between populations. Therefore,
understanding the population genetic structure and connectivity of the New Zealand scallop will assist with the
sustainable management. For this study, 12 polymorphic microsatellite markers were developed de novo and
tested on tissue samples collected throughout the geographic range of the species. F-statistics and Bayesian
clustering methods were used to determine the genetic structure of the New Zealand scallop. The results
highlight the utility of the new genetic markers for understanding the current levels of variability within and
between populations or stocks and emphasize the importance of using updated information to adjust
management plans.

Studies on the impacts of ocean acidification on fish larvae have shown that individuals exposed to elevated
CO2 are unable to detect cues important for orientation and habitat selection. The use of sound is most likely a
main orientation cue influencing these behaviours. We tested, in an auditory choice chamber, the response of
late stage larvae of painted-goby and sand-smelt, to daytime reef recordings, and the effects of exposure to
elevated CO2 conditions (pH ~7.6) on the auditory-mediated behaviour. The two species were differently
affected by exposure to CO2 - sand smelt did not show any preference or avoidance behaviour when exposed
to reef sounds, but exposure to elevated CO2 affected the directional response of painted goby, with control
larvae actively avoiding reef noise, but larvae from high CO2 treatment showing an opposite response. This
species-specific response might be due to different response to reef sounds, and not different sensitivity to
CO2 exposure, as one is a typical reef fish (painted goby) and the other is a pelagic species (sand smelt),
which probably does not react to reef sounds. The disruption of the auditory abilities could have significant
consequences on the survival of species during the early life history stage.

Although sandeels are central species in marine food webs and a main trophic source for many predators,
knowledge about their ecology and their migration pattern is limited. Movements and connectivity between
Essential Ecological Habitats (EEH: spawning, nursery, feeding and resting habitats) was investigated using
otolith microchemistry by comparing multi-elementary fingerprints from the center to the edge of otoliths. Three
species of sandeels: Hyperoplus lanceolatus, Hyperoplus immaculatus and Gymnammodytes semisquamatus
were sampled in subtidal sandy banks of Northern Brittany, France in spring and autumn 2012. Seasonal
variations of specific composition and age structure were highlighted. By crossing age structure and results of
otolith microchemistry, we hypothesized that H. lanceolatus seemed to occupy subtidal sand banks as adult
and sub adult whereas H. immaculatus occurred only from 2+ life stage, suggesting that they both used a
different habitat for their early life stages (nursery). On the contrary, G. semisquamatus appeared as the more
resident specie as all life stages being represented in subtidal sand banks. Finally, we highlighted that these
sympatric species have contrasted ecology and migration loops and different habitats along their biological
cycle, which may reduce interspecific competition. These findings also have implications for management
perspectives.

Most extant marine invertebrates and fishes have a planktonic larva in their life cycles, which is dispersed by
ocean currents. Larval dispersal and supply is basic for the local occurrence, abundance and connectivity of
populations. This presentation synthesises recent work on the larval ecology of a widespread coastal
invertebrate, the shore crab Carcinus maenas, highlighting the interactions between larval biology and currents
affecting population connectivity. Microsatellite data indicate a "panmitic" populational unit extending from the
Gulf of Cadiz to Wales. A validated numerical bio-physical model incorporating larval biology, however,
indicates that the average realized dispersal in the west Iberian margin is <200 km. Application of this model to
investigate multi-annual dispersal patterns indicates that the direction of larval transport is correlated with the
annual North Atlantic Oscillation index and is usually asymmetric, with a predominant equatorward transport.
The model also predicts a source-sink cell between the Muros-Noia and Mondego estuaries, where
populations in the north consistently act as net sources of larvae supplying net sink populations to the south.
This source-sink cell appears to be related to the existence of habitat gaps, coast geometry and an
oceanographic retention effect associated with upwelling dynamics.

understanding of spatial patterns of species distribution, and on the make-up of genetic connectivity among

MPAs (Portofino, Tavolara, Cabo de Palos and Port-Cros) was investigated. Mitochondrial COI sequence
polymorphism of Patella rustica and Patella caerulea populations sampled in and out each MPAs was
analysed. The results of this study will allow us to understand the efficiency of the MPA network in terms of
connectivity and genetic variability within and between MPAs and will further give a contribution to the

may be influenced by the duration of its pelagic phase. In this study we conducted otolith microstructure
analyses on the sagittal otoliths of larval black-faced blenny (Tripterygion delaisi) from the Arrabida Marine
Park, Portugal in order to gain insights into its pelagic larval duration. T. delaisi, a small demersal fish found in
shallow near-shore rocky habitats is of particular interest because several of its life history characteristics
suggests that it may exhibit a high degree of self-recruitment. In this MPA the presence of all the different larval
stages close to shore indicates that local development of this species is occurring. Enumeration of daily growth
rings on the sagittal otoliths of T. delaisi larvae collected during the period April – September 2012 and 2013
indicates that the PLD of T. delaisi may be greater than that found in previous studies conducted in the
Mediterranean. If verified the PLD of T. delaisi in the Arrabida Marine Park would be similar to the values
reported for other triple fin species from temperate regions. With such extended PLD, connectivity can be
expected to be large. Nevertheless, the evidence of local growth can indicate local retention. More studies are
needed to best understand connectivity patterns and the mechanisms underlying dispersal patterns in this
species.

In this study we analyzed the existence of a stock structure on the populations of sea lamprey, Petromyzon
marinus L., sampled in the major Portuguese river basins, using morphological characters, genetic markers
and heart tissue fatty acid signature. In both morphological and physiological analysis, the multiple discriminant
analysis revealed statistically significant differences among groups, and the overall corrected classification rate
estimated from cross-validation procedure was particularly high for the cardiac muscle fatty acid profiles (i.e.
83.8%). Genetic analysis, however, did not reveal significant differences between groups. Fatty acid analysis
showed that all lampreys from the southern Guadiana group were correctly classified and not mixing with
individuals from any other group, reflecting a typical heart fatty acid signature. Our results revealed that 89.5%
and 72.2% of the individuals from the Tagus and North/Central groups, respectively, were correctly classified,
despite some degree of overlap between individuals from these groups. Detected differences are probably
related with environmental variables to which lampreys may have been exposed during their life cycle, rather
than derived from a genetic basis. These results suggest the existence of three different sea lamprey stocks in
Portugal, possibly promoted by seabed topography isolation during the oceanic phase of the life cycle.

The dispersal of mussel planktonic larvae is crucial to describe population dynamics and to develop spatial
management strategies. Distinctive geochemical signatures on calcified structures have been recently
implemented as a natural tagging technique to study larval dispersal patterns and connectivity matrices
between populations. We investigated the microchemistry of bivalve larval shells (Mytilus galloprovincialis) in
order to produce an atlas of natal trace-elemental signatures along the Portuguese west coast. Larvae of
mytilid mussels were cultured in situ, at 19 sites for 6 days and the shells were analyzed for a set of trace
elements using laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS). According to our
results, 3 distinctive signatures were identified along the coast, corresponding to 3 regions: Arrábida, Baía de
Cascais and Promontório da Estremadura (PERMANOVA; p<0.001). Linear discriminant analyses allowed for
a high reclassification success (74%-81% of jackknifed cross-validated cases correctly classified) based on 8
65
of the 16 trace-elements analyzed (B, P, Co, Cu, Zn, Ce, Pb and U). Shell concentrations showed highest
values of Zn in Baía de Cascais and higher Pb and P in Arrábida than in Promontório da Estremadura. These
results indicate that the development of reference chemical signatures can be a powerful tool to identify
population sources, track larvae trajectories and study population connectivity of mytilid mussels.

A decade of declining Pacific halibut (Hippoglossus stenolepis) abundance in US and Canadian waters has
prompted the International Pacific Halibut Commission (IPHC) to broaden its stock assessment process from a
single-model approach to the use of an "ensemble" composed of multiple models each with unique structure.
Throughout the IPHC’s nearly 100-year history, there has been ongoing debate regarding the appropriate
geographic extent over which to calculate various stock metrics and apply specific management actions. Still,
an underlying paradigm of the assessment and harvest policy has long been the existence of a single unit
stock; a paradigm generally supported by historical (electrophoretic) and modern (nuclear microsatellite)
genetic analyses. In contrast, data from recent electronic tagging (fishery-dependent passive integrated
transponder; fishery-independent satellite-transmitting archival) studies indicate segregation into regional
components at time-scales relevant to prosecution of the fishery, and analyses of bomb-produced radiocarbon
14
( C) in juvenile and adult otoliths suggest complex spatial recruitment dynamics that remain poorly
understood. Here, the results of these studies will be reviewed, with attention to connectivity among the
region’s major oceanographic basins (the Gulf of Alaska, eastern Bering Sea, and Aleutian Ridge) and
relationships between temporal scales of connectivity and associated management metrics and objectives.

The black-lip pearl oyster (Pinctada margaritifera) is cultured extensively to produce black pearls, especially in
French Polynesia’s atoll lagoons. This aquaculture relies on spat collection, a process that can be optimized by
understanding which factors influence larval dispersal. Here, we investigate the sensitivity of P. margaritifera
larval dispersal to both physical and biological factors in the lagoon of Ahe atoll. Coupling a validated 3D larval
dispersal model, with a growth model (DEB), the variability of lagoon-scale connectivity patterns and
recruitment potential is investigated. We found that the mean pattern of potential connectivity was driven by the
southwest and northeast main barotropic circulation structures, with high retention levels in both. Destination
locations, spawning sites and PLD were the main drivers of potential connectivity. Differences between
potential and realistic connectivity showed the significant contribution of the pearl oyster broodstock location to
its own dynamics. Finally, application of the growth model highlighted crucial role of trophic conditions in
determining the larval supply. These results provide new cues to understanding the dynamics of bottomdwelling populations in atoll lagoons, and show how to take advantage of numerical models for pearl oyster
management.

Exogenous floating marine debris (EFMD) negative impacts on marine habitats has been reported for longer
than five decades, but still presents a worldwide threat to populational and environmental health. The aim of
this paper is to evidence research done regarding EFMD impacts on habitats. This paper contributes to the
66
thematic of EFMD negative impacts on habitats in several ways. First, an updated bibliographic research was
accomplished. Second, trends in EFMD research impact on habitats were found for distinct regions of the
globe. Third, a diversification of research interests through time was obtained, but with a regional differentiation
to areas with significant economic and environmental interest. Fourth, research gaps were identified for the
habitats in study. Among these, the following: very little attention has been given to understand the EFMD
quantitative links between the distinct habitats under scrutiny; more needs to be done to understand how the
distinct types of EFMD dynamics affect the environment; and differential regional research settings needs to be
implemented for critical habitats protection.

Population structure and connectivity are influenced by physical, biological and ecological processes and
interactions that impact over a range of temporal scales. Therefore the best inference on population
connectivity may be achieved by using multiple and potentially complementary techniques that integrate over
different scales. Here the advantages, handicaps and potential pitfalls of two natural markers (i.e. otolith
geochemistry and microsatellite DNA markers) are presented and discussed based on the case study of two
marine fish species. In addition, the difficulty of objectively integrating data of different natural markers is
addressed. Generally, otolith geochemistry provides information over an ecological time frame and on a fine
spatial scale, while microsatellite DNA markers report on gene flow over evolutionary time scales and therefore
act on a broader spatio-temporal resolution. As many marine fish show low genetic differentiation and high
gene flow otolith geochemistry may complement and enhance connectivity assessments in these species.

Lagrangian simulation of particles to study larval dispersion
Rodriguez L, Santos F, Gomez Gesteira M
Corresponding author: [email protected] (L Rodriguez)
This study aims to simulate Lagrangian trajectories for different numbers of particles or "larvae" with a passive
behavior (setting at a depth of dispersion). It also seeks to analyze the dispersion of those particles by using
the data of the components U, V and W from the speed of currents provided by the database SODA. This
study used a biological parameter (planktonic larval duration, PLD) of a specific starfish larva (Sclerasterias
tanneri larvae) that can be found at the Gulf of Mexico at different locations. Particles were released in October
close to the Florida Strait. Those particles have been tracked for 660 days recording their position every 15
days for the period 1899-2010. The principal aim is to analyze if particles could cross the North Atlantic Ocean
from the Florida Strait and reach the European shelf. To do this the number of particles that cross 340°E close
to European shelf was analyzed and the final position of particles was clustered to check for trends in their
displacement. The results showed an increase of particles that cross the 20°W meridian and that particles are
moving more and more northeastward.

An acoustic telemetry array was used to monitor the movements of the white seabream Diplodus sargus, the
Mediterranean moray Muraena helena and the European conger Conger conger within the Marine Protected
Area (MPA) of Pessegueiro Island, south western coast of Portugal. A total of 19 specimens of D. sargus
captured in July 2012, and 19 specimens of M. helena together with 6 C. conger captured in July 2013, were
tagged with Vemco V9 acoustic transmitters, and released inside the MPA. The tagged fish were monitored for
2 months by an array of 20 VR2w underwater acoustic receivers that covered the entire MPA. Data showed
that the majority of the tagged fish spent most of the study period within MPA limits. Activity and movements of
the tagged species were influenced by habitat, diel cycle and tidal patterns. Distinct patterns of habitat use
67
were related with some of the environmental parameters and preferential movement corridors. Halting
locations (possibly refuge) were also identified within the AMP. High site fidelity was confirmed during the
summer, the only season analyzed. The surrounding area of Pessegueiro Island proved to be important for the
2
studied species which indicates that the protection measures in place, even though it is a small MPA (~4,5 Km
of total area), can be important to help maintaining the sustainable exploration of these species in the
southwest coast of Portugal.

Resource subsidies associated with pulsing environments strongly influenced the structure and dynamics of
food webs. Here, we use stable isotopes to estimate the magnitude of a food web subsidy derived from
hydrologic pulsing in a coastal lagoon on the Atlantic coast of southern Brazil. Our extensive monthly-based
sampling (N=682) of food web components enabled us to view food web structure like a movie rather than a
snapshot, and provided a basis for estimating the timing and magnitude of a spatial food web subsidy to
estuarine consumers. Freshwater, estuarine and lagoon mouth food webs were fairly isolated and dependent
on local production sources during the beginning of the study, but a flooding led to high connectivity of these
compartments, primarily with organisms and energy moving from the freshwater zone to the estuarine zone.
Mixing models revealed that during flooding conditions (April to July) freshwater-derived sources (C3 plants
and seston) contributed to estuarine residents. Contributions of these sources for estuarine fishes were nearly
zero in April, but gradually increased to up to 40% in June and July. Human activities reducing flood duration
and intensity in this system may negatively affect estuarine communities by disrupting subsidies from
freshwater.

Sound management and decision making relies upon a flow of reliable information from all relevant sectors,
public and private, including a transfer of robust, impartial scientific evidence into the policy arena. Judgements
of risk and uncertainty come in to play, as well as wider political drivers. Engaging decision makers in science
doesn’t just mean making research results available. Science findings, reports and publications are only a
starting point in providing evidence to decision makers. It also means helping them understand the implications
and working with them to decide how to respond, and what additional research, monitoring or other activities
are needed. The information needs to flow both ways. However, the field of communication in the European
science-policy landscape is quite fragmented, with many organizations, platforms and networks communicating
simultaneously. Decision makers hear different opinions and must make value judgements. Hence, improving
management and decision processes will largely depend on the improvement of coordinated communication
between scientists and managers or decision makers. Scientists and decision makers must work more closely
together to ensure research outcomes are understood, relevant and achieve maximum uptake and impact.
Though valid attempts have been made, it is clear that a one size fits all approach to science-policy
mechanisms across the diverse interests of the marine and maritime communities will not work.
Due to the fragmentation and lack of coordination, both in research as in science-policy interface activities,
additional initiatives have been taken to obtain more integration in the European landscape. One of them is the
creation of the Joint Programming Initiative for Healthy and Productive Seas and Oceans. This is a
coordinating and integrating long-term platform, open to all EU Member States and Associated Countries who
invest in marine and maritime research. In its role as a high-level coordination platform, JPI Oceans will focus
on making better and more efficient use of national research budgets, which represent about 88% of the
marine-maritime funding within Europe. To achieve this, countries are expected to coordinate national research
activities in the broadest sense, group resources, benefit from complementarities and develop common
research and innovation agendas, as a basis for long-term cooperation. While bringing together the interested
countries JPI Oceans also aims to contribute to establishing efficient mechanisms for interaction and
knowledge transfer between the scientific community, industry & services, and policy makers at high level to
more effectively solve the grand societal challenges regarding seas and oceans. This process would build on
the structures already existing, working with existing players at national and European level, rather than
duplicate or invent new ones. Proposals for implementation of principles such as a two-way science-policy
interface, co-designed research programmes, dual-use infrastructure for research and monitoring and greater
data sharing are needed and currently requested to be developed at an international scale, including future
contributions from JPI Oceans member countries.

The management of environmental decision-making in Western societies is confronted with struggles that stem
from the many institutions involved in decision-making processes. On top of that the handling of ecological
complexity and its interconnectedness with social complexity is an additional challenge. Effective links between
knowledge and decision-making are required but such processes easily suffer from, what could be called the
‘Environmental Knowledge Paradox’: an increased need for knowledge which does however not imply a
decrease of uncertainty and contestation. We can do better by changing three different aspects. Firstly, formal
and informal stakeholders need to be able to play the role of informing all the parties involved during all the
steps of the decision making processes. This will contribute to ‘divergence’ of ideas, options and solutions.
Secondly, more than one consultant needs to be involved in the exploratory phase of any initiative to
guarantee standardly a ‘second opinion’. One consultant needs to get the task to study the situation and its
future from a certain perspective e while the second needs to do the same but with different (model) tools
69
compared to the other. Thirdly, the use all available techniques (statistical models, numerical models,
analytical models, dynamic ecological simulations, static analyses of biological networks or food webs) needs
to be accepted while exploring any impact. We suggest this because we are aware of the fact that all
approaches have their advantages and restrictions. To make this all to a success it is also required to focus on
data collection via a wide compliance monitoring program. In suitable knowledge-practice interface
constructions these data can feed models, statistical tools and other mathematical approaches to make any
policy making trajectory to a widely supported and accepted process instead of the current ‘top-down’
approach.

Floods in estuaries can be driven by different forcing mechanisms from ocean and inland sources and are
often aggravated in urban areas by insufficient drainage conditions. Sea-level rise and extreme climate events
can exacerbate water levels inside the estuaries. Developments are being made to reduce the uncertainty of
forecast tools in order to provide reliable flood predictions that can support risk assessment and management
strategies. The integration of historical events data analysis in hazard forecasting can contribute to a better
knowledge of the dominant flood drivers and to improve the validation of the models. In the present work a
data base of historical flood events was constructed for the Tagus estuary (Portugal), which particular
geometry, hydrodynamic conditions and territory occupation promote natural and urban flooding. Historical
events were assessed through newspaper reports, technical and scientific publications, municipal and civil
protection records, online databases and hindcast simulations. Possible flood drivers (tide, storm surge, wind,
waves, precipitation and fresh-water discharges) were evaluated for the higher impact events including the
episode that resulted from Xynthia storm that reached the Portuguese coast on February 2010. The results
provided a good insight about the contribution of the different forcing mechanisms in Tagus flood events.

The exclusive economic zone of coastal countries are coming under increasing pressure from various
economic sectors such as fishing, aquaculture, shipping and energy production. In Europe there is pressure to
expand the maritime economic sector without damaging the environment by ensuring that these activities
comply with legally binding Directives such as the Marine Strategy Framework Directive (MSFD). However,
monitoring an extensive maritime area, particularly during periods of environmental change, is a logistical and
economic challenge. Remote sensing is considered one of the most cost effective methods for providing the
spatial and temporal, environmental data that will be necessary for the effective implementation of the MSFD.
However, there is always a concern about the uncertainties associated with remote sensing products. This
presentation will show how in situ data from the SW Iberian Peninsula has been used to validate the quality of
remote sensing products from the MEdium Resolution Imaging Spectrometer (MERIS) sensor of the European
Space Agency for ocean colour products such as water leaving reflectance and algal pigments.

Rapid changes to the estuarine landscape resulting from anthropogenic pressures necessitate new tools to
support informed management, applicable to the large scale impacts of climate change and urbanization.
70
However, ecological baselines to support such management are lacking for most tropical and subtropical
organisms. Citizen scientists provide a solution to this problem as they can rapidly collect data sets over large
scales. The present project investigated the potential of novel photo and video techniques for citizen science
based estuarine management using three fundamental ecosystem components. In particular, Crab Scan
samples intertidal crabs using photography, Mangrove Watch conducts shoreline assessments including
vegetation mapping and Fish ID identifies fishermen’s catch in a GPS referenced database. The use, limitation
and attraction of the different techniques for citizen science projects were assessed and a combined toolkit for
estuarine management developed. Additionally, an integrative framework was developed combining data from
the three different ecosystem components, vegetation, intertidal crabs and fish, as a basis for informed
management. The resulting framework provides a cheap, easy to use alternative to long term monitoring,
capable of rapid assessments as well as management planning without field data.

This work proposes a regionalization of marine waters south of the Iberian Peninsula based on empirical
orthogonal functions and GIS analysis. The regions identified are consistent and correspond to hydrological
mesoscale and macroscale structures well characterized from physical and biological viewpoints. Although it is
difficult to determine the boundaries of a fluid continuously moving, the procedure used recognizes the most
frequent patterns and can be used to reference geographically the most likely position of the limit among the
regions. Once the regions are established, the connectivity among them is addressed by means of geostrophic
currents derived from altimetry data. The main geostrophic circulation patterns depict an elevated connectivity
in the area that might facilitate the conservation and recovery of species, but also imply a higher vulnerability to
negative externalities and highlight the need for models, marine spatial planning, and coastal management
approaches that include the pelagic ecosystem and connectivity of the seas. Furthermore, the results confirm
that the cooperation between public authorities at different levels (local, regional, state) as well as among
riparian countries is essential for marine spatial planning and prevention of potential risk derived from
upcoming marine activities in the framework of the 2020 agenda and Blue Growth strategy.

Seamounts are considered hotspots of biodiversity and productivity yet the influence of Gettysburg (in Gorringe
Ridge), Ampere and Seine Seamounts on the productivity of the region is poorly understood. These
seamounts are located within the “Portuguese extended continental shelf” proposal submitted to the United
Nations. This work presents in situ and satellite data results aiming to 1) determine the effect of seamounts on
the abundance and composition of phytoplankton communities; 2) use satellite data as a tool to characterize
seamounts ecological features. Oceanographic cruises in May/June 2009 and December 2010 collected data
on HPLC photosynthetic pigments, cell abundances (by flow cytometer) and nutrients above the Gettysburg,
Ampere and Seine seamounts, and in nearby sites . Satellite data include ocean colour (from the ESA OCCCI project) and SST contemporaneous with in situ sampling as well as altimetry climatology. In situ results
show a more heterogeneous phytoplankton community above the seamounts in comparison to the surrounding
region. From the Altimetry climatology, it is clear that Ampere is influenced by the warmer water off Azores
current, whilst a cooler subtropical northern flux dominates the Gorringe. This work aims to contribute to a
future establishment of these seamounts as Marine Protected areas.

The south of Chile, and specially the inner sea of Chiloé hold an increasing number of marine and coastal
based economical activities. In the last twenty years, the aquaculture blooming with salmon aquaculture and
more recently mussel culture has been leading the exports of global markets, demanding a large amount of
space of the marine areas. Recently the new development plan with horizon in 2020 has agreed to impulse the
tourism of this area, especially in regard to eco-tourism (wildlife observation, sports and recreational tourism).
A zonation process has been switched from national and regional authorities, proposing three types of zones
according to strategic interests in which the proposing space of eco-tourism is integrated within the same area
as the aquaculture or conservation areas. In the present study, we identify spatially the exact actual and
potential occupation and demand of coastal and marine ecosystem and environmental services. Using
interviews and surveys to local stakeholders and experts, we assign weights of ecological, economical, equity
and cultural importance and human wellbeing delivery to the activities in operation. Then, using GIS and Invest
overlap tools, spatial models of the importance and impact were created in order to locate the areas where
micro-planning efforts are urgently required. Results show seven spatial overlapping hotspots between human
activities where micro-zonation is needed in order to manage the use of ecosystem services in space and time.
Ecosystem based tourism is called to be the next emerging economic engine in the future at local level but this
is only likely if proper spatial identification of ecosystem is done.

Transitional waters are characterized by important environmental gradients which make difficult to discern
among anthropogenic and natural stressors over the ecosystem. Here, we use Chromophoric Dissolved
Organic Matter (CDOM) as an indicator of the Environmental Quality of a Mediterranean protected coastal
lagoon (Messologhi, Greece). Four seasonal sampling campaigns were performed. Lagoon’s surface water
samples were collected covering its entire surface. Additionally, samples were collected from the adjacent
coastal ocean and the main freshwater tributaries to the lagoon. These included two freshwater pumping
stations draining an intensively farmed area west to the lagoon and the emissary of a Wastewater Treatment
Plant (WWTP) discharging to the lagoon. Relevant physical and chemical parameters including Excitation
Emission Matrix fluorescence of the CDOM were determined. Results characterized the pumping stations and
the WWTP as significant sources of nutrients and, potentially, other pollutants to the lagoon. Nevertheless, the
high degree of mixing and dilution of these sources within the lagoon made difficult to evaluate the area
affected by the discharges. PARAFAC analysis identified three labile and three humic-like components within
the CDOM. Principal Component Analysis of the CDOM characterized humic-like components as powerful
tracers of each end-member into the lagoon. Moreover, associated CDOM labile components offered valuable
information on the organic matter alteration during mixing and dispersion of these end-members into the
lagoon. CDOM showed to be a promising indicator for environmental quality evaluation purposes of transitional
waters.

Corresponding author: [email protected] (AV Mansur)
River Mouth Systems (RMS) are complex socio-ecological systems that are subjected to multiple pressures
from global change, including climate change and human activities. The combined effect of the resulting
pressures increases vulnerability and results in risks to the preservation of the environment, the functioning of
the ecosystem as well as to the social and economic development of RMS. The design of science-based
management strategies depends on understanding RMS and their multiple complexities. The use of indicators
to understand complex processes can make an important contribution to assess and manage RMS. Based on
72
that, this framework addressed the general pressures affecting the vulnerability of RMS and proposed
indicators for their vulnerability. The approach is multi-criterion, including natural hazards, hydrological,
morphological, ecological, ecosystem-services and social-economic indicators, thereby providing a holistic
view of the relation and interaction of multi-disciplinary issues affecting the vulnerability of RMS. The proposed
framework explains how the vulnerability due to multiple pressures from Human activities in combination with
environmental factors in RMS can be combined and assessed by local managers for site-specific monitoring.
Such assessment further contributes to the knowledge base required by the decision makers in order to
develop sustainable practices in RMS.

Estuaries are among the most productive ecosystems on Earth, providing very important services. A high
number of them are also under strong anthropogenic pressures, including contamination by hazardous
chemicals from both continental (e.g. industrial and urban discharges) and offshore sources (e.g. oil spills).
The environmental risk assessment (ERA) of these chemicals is crucial to support protective measures,
management and remediation actions. A fundamental step in the Problem Formulation of the ERA process is
an effective assessment of the contamination sources and system vulnerability. In the present study, a general
framework to assess the system vulnerability applying both inter- and intra-system analysis, based on the
multi-metric index approach was developed. This framework delivers information on the system’s vulnerability,
identifies especially vulnerable/affected zones of the system (spatial discretization) and the most critical
period(s) for contamination events (temporal discretization). This information is of great importance as it
provides orientation of “where” and “when” management measures should be implemented. The framework
was tested using the Minho River estuary as a case study, considering the best and worst case scenarios for
both continental and offshore (reaching the coast) contamination events, and evaluating the ecosystem
probable responses.

Systematic processes of land use/land cover change to identify relevant driving forces: implications
on water quality
Teixeira Z, Teixeira H, Marques JC
IMAR-CMA - Marine and Environmental Research Centre, Portugal
Corresponding author: [email protected] (Z Teixeira)
Human-induced driving forces are responsible for environmental pressures and their identification is essential
to evaluate the potential impacts of human activity on the status of surface water, as well as to design
interventions that enhance positive and minimize negative impacts. Land use and land cover changes (LULC)
are important drivers to water quality. However, measuring LULC through transitional matrices is insufficient to
detect the most relevant drivers, as they are not able to distinguish between random and systematic
transitions. The goal is to describe a method to characterize drivers from dominant LULC changes, recognizing
that the processes of transition to other uses are sources of stress with potential effects on water bodies. We
quantified driving forces from LULC change for nested regions within the Mondego river basin in 1990, 2000
and 2006. Then we discussed the implications for the environmental water body condition and management
policies. The fingerprint left on the landscape by some of the dominant changes found, such as urbanization, is
low due to their proportion in the geographic regions under study. Yet their consistency reveals strong signals
of change regarding the pressures acting in the system. Our work identifies systematic transitions relevant for
future water management purposes.

The FP7-funded LAGOONS project - Integrated water resources and coastal zone management in European
lagoons in the context of climate change - comprises four case study lagoons with a wide and balanced
geographical distribution and different characteristics (http://lagoons.web.ua.pt/). The selected lagoons are: Ria
de Aveiro Lagoon in Atlantic Ocean (Portugal); Mar Menor in the Mediterranean Sea (Spain); Vistula Lagoon in
the Baltic Sea (Poland/Russia); Tylygulskyi Lagoon in Black Sea (Ukraine). The oral presentation will discuss
the methodological concept and present some of the central results obtained so far in the LAGOONS project.
Lessons learnt so far highlight the importance of science-stakeholder and the policy-stakeholder interface in
the present-future management of these coastal zones. A central aspect is how to enhance connectivity
between research and policy-making, and how can such a bottom-up case study approach be useful and
transferable to lagoons management at a pan-European level.

A roadmap towards integrating benthic ecosystem functioning in marine decision processes

Current marine decision tools often include distribution maps of benthic communities, or rare species. While
this indeed helps protecting rare species or maintaining biodiversity levels, it does not cover the functioning of
the sediment. Sediments indeed important for the mineralisation of organic matter, providing nutrients to the
water column, a process intimately linked to the MSFD descriptor “Sea Floor Integrity”. However, benthic
mineralisation processes are difficult to measure in routine monitoring programmes. Therefore, we studied
sedimentary biogeochemical cycling (oxygen consumption, nitrification/denitrification) at 10 coastal stations in
the Southern North Sea on a monthly basis in 2011. We used linear regression with a generalised least-square
extension to model the relation between these processes and macrofaunal functional diversity, summarized as
the bioturbation potential index. We further identified the most important organisms contributing to this index.
We used non-linear quantile regression models to predict the abundance of these species at a large
geographical scale, and combined this with available biomass data to estimate a minimum bioturbation
potential. Finally, we will produce maps of ecosystem functioning intensity based on our model relating
bioturbation potential to mineralisation processes. This will allow decision makers to take into account seafloor
ecosystem functioning into relevant decision processes.

The present work developed an integrative methodology to evaluate the adverse effects of impacted estuarine
sediments to human and ecosystem health, taking the Sado Estuary (Portugal) as a case study. The best
professional judgment for a Weight of Evidence (WOE) approach was based on: i) human contamination
pathways; ii) human health effects; iii) human consumption of local farming produce; iv) contamination of wells
and soils; v) contamination of estuarine sediments; vi) effects on commercial benthic organisms, and vii)
genotoxic potential of sediments. Each of these WOE were ranked into levels of ecological or human health
risk, according to a tabular decision matrix. Fifteen experts scored two fishing areas of Sado estuary from a
scale of risk and respective management actions, assisted by the comparison to a reference scenario. Overall,
the estuary is moderately impacted by complex mixtures of toxicants, affecting the ecological status, as
74
assessed through multi-range endpoints in commercial species. Although no clear evidence of contaminantrelated adverse health effects in the local population was found, background pollution constitutes a risk factor
for the development of chronic-degenerative diseases that have a long latency period before being
symptomatic. The approach suggests that expert judgment and qualitative assessment are solid tools to assist
decision-making integrative management of high-complexity transitional ecosystems.

Coastal communities have been repeatedly threatened by the inherent ephemeral character of the coast.
Morphological changes related to climate events and sea level rise have displaced coastal communities over
the past. However, it has never prevented the occupation of this fragile source of wealth. Conversely, the
socio-economic impact of high energy events over the coast is dramatically increasing due to the growing
occupation of the coast and it is expected to aggravate in face of future sea level rise and shifts in storminess.
This situation raises the need for adopting alternative Disaster-Risk-Reduction measures, which should feed
from lessons learned and user knowledge and needs. Here, we illustrate the problem of living in the coast at
risk and explore the reasons behind this constant fight against nature. For that, we examine the socioeconomic and environmental frameworks of the Ria Formosa Natural Park and ran a set of interviews to
provide a frame for understanding the culture of risk in a system with multiple stakeholders. The results state
out ways of living and acceptance of risk. However, they also identify the absence of communication between
different actors as the constraint for effectiveness and acceptability of disaster risk reduction measures.

The Belgian coastline is a dynamic environment where currents, waves and wind interact with the natural
coastal defence system of beaches and dunes. In theory, the coastline should withstand a 1000 year storm
event, but at its weakest links only a 100 year protection level is currently reached. Pending the realization of
the ‘Master Plan for Coastal Safety’, the weakest beaches are annually maintained with beach nourishments.
In general, phased nourishment with natural sediment and beach slope during winter are recommended,
urging for an optimization of the technical nourishment aspects. When considering beach nourishment in the
neighbourhood of European protected sites, one must take into account the strict regulatory framework with
respect to Natura 2000, which is included in the Habitats Directive (Directive 92/43/EEC). The difficult and
sometimes very incoherent application of the rules of nature conservation on beach nourishment, illustrates the
need for a more coherent legal framework with an ecosystem based strategic approach, allowing for onsite
mitigation and or offsite compensation. To investigate whether intertidal beach nourishment has a significant
negative impact on the global conservation status of nearby Natura 2000 areas, a fourfold assessment
approach was created and followed in some Belgian case studies.

Societies are a major force in global change, simultaneously shaping the ecosystem dynamics and depending
on its functioning, meaning that humans and nature are strongly coupled, which reinforces the need to
integrate both biophysical and human dimensions in the ecosystem management. Following this line of
thinking, this presentation looks at the main drivers of change in Ria de Aveiro coastal lagoon and responses in
a holistic way. The methodological approach is based on the identification of pressures in ecosystems of Ria
de Aveiro (Portugal) coastal lagoon and how they are translated in terms of ecosystem services and benefits to
75
society; and the analysis of what are the actions that are being taken - at local and regional, governmental and
individual level – in order to cope or minimize these impacts. Finally, the trade-offs between environmental and
other social goals that may arise are analysed.

Species distribution models (SDMs) are currently gaining interest due to their ability to predict species’
potential distribution, by combining species occurrence with environmental estimates. Their use spans fields
such as ecology and environmental management. With SDMs informing conservation strategies, it is important
to know how trustworthy their predictions are. In order to relate the performance of such models with species’
ecological characteristics, distribution models for 21 fish species occurring in estuaries from the Portuguese
coast, were built at two different spatial scales. SDMs’ accuracy was assessed with sensitivity, specificity and
the area under the curve (AUC) of receiver operating characteristics plots. Relationships between measures of
accuracy and species ecological characteristics were then examined. Species final models presented
differences between the considered scales, and predictors as “estuary” and “sampling month” were often
selected at both scales. Measures of model accuracy presented differences between species and scales, but
generally higher accuracy was obtained at smallest spatial scales for the most abundant species. Among the
ecological traits tested, species ecological guild, migration patterns and spawn period were the most influential
on models’ accuracy. This analysis will help to distinguish between species whose occurrence is reliably or
less reliably predicted by distribution models.

Effective ecological predictions require large amounts of data for model parameterisation. Furthermore,
although uncertainty of predictions is reported more frequently now than historically, understanding of
uncertainty is not evident in many management or public engagement approaches. Bayesian belief networks
(with some limitations, addressed in this study) create an intuitive method to model changes in ecological
communities and present intuitive measures of certainty in their outputs. They are able to incorporate sparse or
uncertain data, or data from multiple sources. This study explores the modification and use of these networks
to predict changes in marine systems, it also explores how expert opinion can be combined with limited
ecological data to create effective predictions. Models are based on rocky shore communities; however, the
underlying concepts are applicable across a range of marine systems. Expert evaluation of interaction
strengths (from rocky shore ecologists from different areas of the world to the study conducted, with a
minimum of postgraduate expertise), combined with data collected from shores in the UK, created robust
models predicting major changes in community structure following disturbance, which were verified by
experimental manipulations. As such, the models provide a robust method to develop end-user friendly
predictive models with limited available data.

Due to their important role in the ecosystem and high economic value, there is a need to assess the effect of
anthropogenic impacts on marine fish assemblages. However, this can only be achieved if natural variability is
minimised through the establishment of assemblage types with a corresponding range of expected values for
community-based indicators under natural conditions. However, while most assessment tools rely on
ecosystem function, bottom-up habitat classification frameworks tend to use species composition. The present
study proposed an innovative framework to define fish assemblage types through metric pairwise constrained
76
k-means (MPCK-means) clustering of sites based on functional guild categories and univariate metrics, an
approach that takes into account within-site variability due to the sampling method and natural causes. This
was followed by a label-based ensemble clustering approach, which finds patterns that minimise information
loss when integrating clustering results from individual metrics. The method was applied using fish
assemblages from near-shore rocky reefs and to offshore soft substrate areas down to 200 m along the
Portuguese coast.

Tuning randomForest to overcome biased classification error and imbalance class distribution in
species distribution models

Corresponding author: [email protected] (P Martinez Arbizu)
Machine learning tools are used to predict the distribution of species in space and time, randomForest being
one of the methods of choice. This recursive partitioning approach is said to be robust against overfitting, but
adjusting model parameters greatly influences prediction accuracy for the different classes. However, review of
current literature shows that default values of model parameters are normally used, and steps for tuning the
model are rarely undertaken. For species distribution models the training dataset consists of a table of
presence-absence of species at given sites. The classification error in these tables is inherently biased,
because while 'present' is based on evidence (assignment of a specimen to a species) 'absent' is based on
lack of evidence (pseudoabsence). In addition, the class distribution in real world marine datasets is frequently
imbalance i.e. most species 'present' at few sites and 'absent' in most sites. These two peculiarities of
community tables (bias classification error and imbalance class distribution) makes randomForest to perform
badly using default parameters. We propose to balance the training errors rather than the training class
distribution as a conceptual way of tuning randomForest models. This results in robust models with superior
performance for the prediction of species presence.

In order to reproduce the water continuum from the atmospheric sources to its evacuation to the open ocean, a
system of integrated models using the Mohid model was designed to include the different spatial and temporal
scales. At the watershed level, the watershed model provided operationally water flow and properties, including
nutrients, for the main river catchments of Western Iberian with a 2 km horizontal resolution. Downstream,
several operational hydrodynamic and biological estuarine applications used the previous results as fresh
water input flows, filling the gaps in the observation network. From the estuarine models, the tidally modulated
water and properties fluxes to the coast were obtained. These fluxes were finally imposed in the Portuguese
Coast Operational Modelling System (PCOMS), a fully 3D baroclinic hydrodynamic and ecological regional
model that covers the Iberian Atlantic front. When combined, this set of models was able to fill gaps in
information and to improve modelling results when compared with the use of river climatologies. The described
methodology is generic and when applied to several estuaries in the Portuguese coast a more precise coastal
circulation was obtained. These results aided to understand the importance of precipitation variability in the
creation of thermal and haline fronts which are relevant to fisheries management.

In a context of global change, the international scientific community recommends an increase in the number of
MPAs for the preservation of biodiversity and the sustainable exploitation of resources. It is thus advisable to
estimate the real efficiency of MPAs and to follow their evolution in time. Within the framework of the French
77
project ANR AMPHORE, research operations were led in two West African reserves: Sine Saloum estuary in
Senegal and PNBA in Mauritania. Information on the fish assemblage inside and outside of the reserves was
collected as well as the fishing activities in the bordering zones of the MPAs. Besides, IBM and ecosystem
modelling were realized, allowing to better understand the real evolution of the fish populations and the
contribution of MPAs to the outside areas. The conjugation of methods used at different scales of observation
and processing, gave a clearer vision of the real efficiency of these reserves: effects are not immediate and
long-term measures need to be set up for ecosystems restoration, with possibly late returns on investment. It
clearly appeared that the systematic implementation of MPAs with severe limitations and bans on use could
lead to real difficulties of acceptability for the local populations.

Knowledge transfer, a fundamental requirement to bring together researchers and managers, implies the
decodification of scientific assumptions, results and uncertainty without compromising the quality of the
information. In coastal zone management delivering accurate nearshore wave data to managers is of
paramount importance. However, in most cases, this information is only accessible to the end-user as: (1)
deep-water wave data sets, requiring further processing to meet the demands of coastal problems; (2)
refraction diagrams picturing transformation of a limited number of previously selected wave conditions; (3)
extensive lists of numbers on wave attributes computed from increasingly complex numerical models. In all
these cases, the physical processes and uncertainty involved are hindered to the majority of managers. This
may lead to a decrease of confidence in scientific results, which can be triggered, for example, by cases where
forecasts depart from observations. Wave transformation matrices, a graphical solution for computing sitespecific nearshore wave characteristics, constitute a tool that bridges over the communication gaps described
above as they not only deliver the requested information but also allow the user to acknowledge the wave
transformation processes and inform on uncertainty. This approach should be explicitly assumed in research
efforts complementing development of state-of-the-art science.

Marine coastal habitats are suffering a rapid and severe degradation mostly due to anthropogenic impacts
such as urban development and poor land-use practices. Previous studies in the Mediterranean Sea have
shown that coastal development activities largely affect water quality and can potentially increase the local
turbidity. The aims of the present study were to assess the habitats vulnerability and potential effects of severe
water turbidity conditions driven by terrestrial runoff. As a case study, the Portofino Marine Protected Area and
the adjacent Gulf of Tigullio (Ligurian Sea, Italy) were chosen. This coastal area is characterized by sporadic
increases in water turbidity in response to high inputs from the surrounding watersheds, of which the main one
is that of the Entella River. CORINE land cover, universal soil loss equation, meteorological data and results
from a local marine circulation model were used to draw a number of different potential scenarios of turbidity in
the study area. Benthic vulnerability maps were obtained by combining benthic habitats distribution, their
sensitivities to turbidity variations, derived from literature, and turbidity scenarios. This study provides essential
information to develop a reliable and robust framework, able to assist decision makers to set appropriate
monitoring and effective management policies.

The shift from sea grass to macroalgae, particularly the “bloom and bust” cycle of the ephemeral Chlorophyta
in estuarine environments has occurred worldwide due to anthropogenic nutrient loading. Contrary to popular
perception, these algal blooms are not harmful to humans, although they are unsightly and negatively affect
aquatic leisure activities. Macroalgal blooms mostly occur in spring and summer when rainfall prior to and
during this time is low. The major macroalgal bloom of 2012 was monitored temporally and spatially using
digitised aerial photographs and cellular automata modelling. Water quality and sediment analysis were
undertaken and existing data from government authorities were also analysed. The results indicated that water
depth and availability of suitable substrate that is found at ICOLL edges, within fringing wetland vegetation, and
among submerged aquatic vegetation are important in determining the extent to which macroalgae can cover
the ICOLL. Nutrient levels in water column and sediment, rainfall, substrate conditions and temperature all
contribute to the extent of algal cover. The data collected are crucial for understanding the mechanisms of the
algal blooms and conditions under which these happen. This is discussed in the light of effective management
options of the intermittently closing and opening lagoons on the Central Coast of New South Wales, Australia.

Following the worldwide trend, the seagrass meadows in Ria de Aveiro lagoon (Portugal) are declining and
currently restricted to intertidal areas. Management actions are important to cease this trend and modelling
approaches arise as useful supportive tools. Thus, the aim of this work is to provide insights of intertidal
seagrass models, followed by the development and application of a model of intertidal Zostera noltii meadows
in Ria de Aveiro. For that, current state of the art of the Zosteraceae seagrass models is provided, identifying
their main limitations and the most relevant processes of intertidal meadows. Literature revision showed that
globally the models available simulate the seasonal dynamics of biomass and nutrient contents in seagrasses.
The main limitations were the absence of tidal cycle effects in intertidal zones and lack of multiple stressors
scenarios to evaluate these systems’ resilience to extreme events. To overcome these constraints and improve
the previous models, the intertidal seagrass model should integrate an add-on tidal-sensitive module, take into
account the relevant processes identified and consider quantitative scenarios in a global climate change
context. With this work, a foremost basis for future developments in intertidal seagrass modelling is provided,

The brown shrimp fishery is very important along the Belgian coast, but conflicts with other activities and
environmental policy impose a heavy burden. Shrimp fishery is faced with spatial restrictions in function of the
newly assigned N2000 area and the Belgian marine spatial management plan. Secondly, there is a conflict
with the potential re-allocation of a dredge disposal site into the shrimp fishing zone. The major obstacle to
adequately manage both cases was the lack of information on the spatial extent of the fishing grounds and
activities (VMS data protected by fishing industry and administration), the socio-economic importance for the
shrimp fishery (no direct link between logbook data and fishing location), and the impact of human activities
(dredge disposal and nature conservation) on the living marine resources. Both conflicts triggered Belgian
policy makers to imply scientific research. VMS and logbook data (also foreign vessels) were made available, a
BACI study was performed, and the effects of all activities were compared. The scientific studies delivered the
necessary information, which allows for a better negotiation for both policy makers and the shrimp fishery. This
governance process shows that transparency of all users on their activities can lead to an appropriate decision
management.

Due to the increasing demands and pressures on water resources, there is a growing need for efficient and
effective implementation of management policies. This study aims 1) to evaluate the awareness of individuals
through a contingent valuation (CV) study, estimating the benefits of water quality improvements in a
watershed (Mondego Basin, Portugal) and 2) to examine how this information may help the design of
management policies. Two CV surveys (one considering the entire Mondego Basin and another considering
just the estuary) were undertaken and respondents’ willingness to pay (WTP) regarding water quality
improvements and ecotourism facilities were evaluated. This valuation approach was tested along 4
geographical sampling levels, inferring the distance-decay effect on respondents. Estimates indicate a WTP
around 30€/year/household to achieve a very good status plus ecotourism facilities, with lower values to
achieve good (around 10€/year) or very good (circa 20€/year) water quality levels. Our findings identify that
both use and non-use values are reflected in respondents’ WTP, showing: 1) a strong relation between socioeconomic respondents’ profile (e.g. income or education) and WTP for environmental quality improvements; 2)
that the distance-decay effect and the usage of the system had a significant influence on respondents´ WTP;
3) a social awareness for environmental issues and economic values (marketable and non-marketable)
attached to ES of aquatic resources. From the results, a set of recommendations are made for decisionmakers towards system conservation and management, acting as an effective instrument to existing EU
policies, namely the WFD.

Most of the scientific literature related with MPA focus on ecological aspects or users conflicts between
conservation and livelihood needs that usually lead to policy and management issues, but few studies have
dealt with other uses such as beach tourism. This can be in part due to the large impacts that those activities
might represent in terms of the MPA conservation, but beach use and related activities can be very impressive
and both impacted if not well managed. Understanding these users’ needs, expectations and motivations could
be as important to MPA success like fisheries or any other subsistence, commercial or recreational activity
management. During the summer of 2013, a survey was conducted to 880 beach-users of Parque Marinho
Luis Saldanha (PMLS) an MPA situated 40 km South of Lisbon, Portugal in order to understand the primary
motivations and perceptions of these stakeholders that can reach over 15,000 daily users. Results, among
others, have shown that these beaches are mainly used by Lisbon surroundings residents and that users
expenditure is relevant in terms of local economy. Traffic jams, lack of parking places (the most negative
evaluated item) and PMLS communication strategy, if improved could contribute not only to a better user
experience but also to support the management of this MPA.

World aquaculture production continues to increase relative to fisheries production. Portugal has priorotised
offshore aquaculture as a strategic sector for expansion provided the activity complies with national and
European laws such as the Shellfish Directive and the Marine Strategy Framework Directive. This requires
routine monitoring of a range of variables to assess the environmental impact of aquaculture activities,
particularly, in areas of high ecological value. The Finisterra S.A. company has an offshore concession for
bivalve aquaculture at Sagres on the SW coast of Portugal within the Costa Vicentina National Park. This
80
company actively incorporates scientific information in its management procedures including an oceanographic
buoy that routinely measures in situ environmental data that is transmitted by WiFi to allow cost effective
monitoring from shore. This data can be directly incorporated into a hydrodynamic model (MOHID) and a
screening model (FARM) to provide ecological and economic optimisation of culture practices. This in situ data
is also being used by an EU project that is developing products from remote sensing data that will provide
relevant and timely information on optical water quality, temperature and ecological variables for the
aquaculture industry, including Finisterra. This presentation will report on the progress of these activities.

The marine and coastal ecosystems around the island of Ireland provide many valuable benefits to the Irish
economy and society. However, increase in population within the coastal zone and exploitation of these
ecosystems mean that many are under threat. This paper uses the TEEB ecosystem services framework to
class the different ecosystem services provided in the marine and coastal zones around Ireland. While some of
these ecosystem services are readily identifiable, such as fisheries, other ecosystem services, such as waste
treatment and carbon sequestration, past unnoticed. This papers uses GIS to spatially identify ecosystem
services provided by the marine and coastal ecosystems. A variety of economic methodologies, including
benefit transfer and travel cost modelling, are applied to estimate values for the ecosystem services. This
knowledge may be used by policy makers in any decision making process affecting marine and coastal
ecosystems. Decisions should not be made based solely on the value of the ecosystem services of an area but
these values may provide another dimension in policy formation within the marine and coastal zones.

The intensity of human pressure on marine systems has led to a push for measures to restrict and prevent
impacts on coastal and marine ecosystems. Integration of the biological, biophysical data and socio-economic
information in GIS assisted the identification of restricted use zones and to construct a strong baseline for
management decisions. Considering the interactions between uses, and the perspectives of stakeholders a
strategic and proactive planning process for regulating, managing and protecting the marine environment was
defined, through allocation of space to the multiple, cumulative and potentially conflicting uses of the sea.
Moreover, this can be envisaged as a dynamic tool as new information can be fed in the system and the
accuracy of the model improved, this represents a very useful feature as the rate of changes in coastal areas
demands a fast yet scientifically sound management answer. A marine spatial planning (MSP) proposal for one
marine protected area (MPA) of São Miguel Island, with delimitation of three levels of protection areas
including no-take areas was put forward. Determinations of high biological value areas and conflicting used
areas was crucial to the MSP proposal as a management tool, with potential to be extended to the other MPA
in the region or elsewhere.

Strategic Environmental Assessment (SEA) is a globally accepted tool for mainstreaming sustainability goals in
the decision-making process. SEA is context-specific and, in the case of small islands, due to the specific
characteristics of these territories (e.g. unique biodiversity and ecosystems, limited resources), existing
methodologies may hinder decision-making processes. An SEA approach that integrates ecosystem services
(the benefits that people obtain from ecosystems) in the process may help enhance SEA practice in these
territories. However, there is a lack of research on this subject focusing on small islands. Therefore, this paper
81
aims to explore how ecosystem services have been integrated into SEA in small islands. This analysis covered
the approaches used for assessing ecosystem services, the ecosystem services addressed and the relations
between ecosystem services and plan typology. This was achieved through a content analysis of a selected
set of SEA reports from the Azores (Portugal) and Orkney (Scotland) islands. Preliminary results showed that
this approach to SEA may enhance the effective integration of sustainability issues into decision-making
processes of small islands, reduce costs of planning and approval times.

Estuaries are complex systems, their morphologic evolution depending on hydrodynamic, geomorphologic,
sedimentologic, biologic and human-induced factors. This complexity makes the forecasting of morphological
responses to sea level rise a challenging task. The focus of this work was to develop a simple model
describing long-term estuarine morphological evolution in response to sea level rise. The model rests on the
assumption that sedimentation rates depend on the considered morphosedimentary units (channels, flats and
saltmarshes) and of immersion times. This model was applied to the Tagus estuary (Portugal) using
210
137
sedimentation rates deduced from isotopes ( Pb and Cs) determined in cored sediment and cartographic
comparison. These data supported the development of an analytical function relating sedimentation rate solely
with a characteristic depth. Preliminary results are in agreement with the general knowledge of estuarine
behaviour: for a sea level rise acceleration scenario, a pronounced reduction in the salt marsh and intertidal flat
areas is forecasted, followed by growth of subtidal flats and channels. This model represents a major advance
in the ability to forecast long-term estuarine morphologic changes coupled with sea level rise and proved to be
a simple but flexible method, with great potential to be used as a supporting tool in estuarine management.

Estuarine and coastal systems are subjected to multiple threats (human-induced or due to climate variability
and change) that may reduce their water quality and ecosystems health. Managing these water bodies
requires the linking of science and decision-making, based on the integration of our current knowledge of these
systems, our predictive capability to simulate various complex processes, and our ability to measure the
relevant physical, chemical and biological variables at appropriate temporal and spatial scales. Coastal margin
“observatories”, which integrate operational modeling systems and real-time monitoring networks, are
becoming vital tools to achieve this goal. High-resolution, process-oriented, numerical models combined with
data provide the basis to understand the systems natural variability and to predict their response to changes.
Implemented in real-time frameworks, these tools allow the continuous evaluation of the system behavior, the
anticipation of hazardous situations and the adjustment of existing monitoring strategies.
The effectiveness of these observatories is demonstrated in two Portuguese estuaries: Aveiro lagoon and
Tagus estuary. The relative role of climatic factors and anthropogenic interventions in the ecological dynamics
of the Aveiro lagoon is evaluated and a pilot surveillance system for early-warning of pollution events (fecal
contamination and eutrophication) under operation in the Tagus estuary is presented.

Maritime Public Domain plays a relevant role for the protection of sea and estuarine banks. In this paper the
results of a research work regarding the role of the Maritime Public Domain (MPD), as it is considered in the
Portuguese Law, is explored within estuarine contexts. The paper describes the main features and analysis the
implementation challenges of this legal instrument for the protection of associated water resources, as well as
close natural resources such as Natura 2000. The interaction between this instrument, the current land-use
and water resources planning systems as well as the permitting system of economic activities common in
estuarine areas allows a wider and critical perspective over the potential and limitations of this instrument. After
the general analysis the analysis is focused on an estuary case study area, the Ria de Aveiro, Portugal, where
its implementation, especially in salt pan areas has been pursued for many decades. The results of the paper
defy the contribution of MPD to the protection of estuarine water and to the biodiversity resources and suggest
new ways to improve its value.

Synopsis
The importance of marine biodiversity is widely recognised for the intrinsic value of habitats and species but
also for its functioning which produces ecosystem services from which we obtain societal benefits. In this
workshop we will provide a brief introduction to these topics and will illustrate the subject with two short
stimulus presentations which will provide examples of biodiversity in coastal wetlands and the wider sea, the
users and the pressures on those areas, the key stakeholders and the different management approaches
considered to balance any conflicts and ensure sustainability. The aim is for a discussion which will be of
interest to those familiar and those less-familiar with the topics: paradigms of the structure and functioning of
marine environments, vulnerable habitats and species, the socio-ecological system, the users, uses of the
system, and management approaches.

This talk will outline the development and application of a new prototype zoning scheme designed specifically
and tested for Scottish waters using a Geographical Information System. The primary aim was to devise a
large-scale, ecosystem-based zoning approach for managing activities within Scotland’s marine environment.
In this zoning scheme areas are designated within different zones according to a combination of both their
ecological features and existing management mechanisms for any activities taking place. For each of the
different zones a series of goals, objectives and strategies have been devised to represent the desired
outcomes for those areas. This prototype zoning scheme aims to facilitate the delivery of long-term protection
to the marine environment, treating areas as whole ecosystems while still enabling a diverse array of activities
to take place in a sustainable manner. The adoption of a zoning scheme such as the one developed here, that
incorporates both activities in the marine environment and important environmental considerations could
provide a new approach for regulating, managing and monitoring marine activities. Such an ecosystem-based
approach to marine management, which integrates existing marine protection and conservation designations
as part of future marine spatial planning initiatives, would provide a tool to manage any potentially conflicting
uses whilst still maintaining environmental integrity.
Historic water management and habitat connectivity in the Uists, Outer Hebrides, Scotland: how an
understanding of the past can inform modern biodiversity management
Angus S

The low-lying western coastlands of the Uists are exposed to the Atlantic and currently experience relative sea
level rise of 6mm/yr. The islands support the finest machair in the world, including species-rich rotational arable
machair and the most diverse saline lagoons in Scotland, as well as a suite of fresh water lochs and marshes.
Low water levels are artificially maintained by drains installed from the mid 18th century onwards, but their
efficiency is threatened by rising sea levels. The drains were preceded by a navigable loch and canal network;
though altered by the more recent drains, the remnant canal routes provide extensive surface and water table
connectivity throughout the lowlands. Water table salinity is at risk from marine flooding and saline intrusion via
saline lagoons. Detailed and repeated LiDAR data capture and monitoring of selected lagoons and water
tables are required to inform water and land management to safeguard biodiversity across a wide range of
linked habitats. Recent experience has demonstrated that an integrated approach to biodiversity management
involving human history and socio-economic factors can play a significant and positive role in local governance
and adaptation planning, with the possibility of applying this experience more widely in Scotland.

The environmental and socio-economic importance of the coastal areas is widely recognized, but today these
areas face severe weaknesses and high-risk situations. The increased demand and human occupation of the
coast has greatly contributed to increase such weaknesses. Today, throughout the world, in all countries with
coastlines, episodes of waves overtopping and coastal flooding are frequent. These episodes are usually
responsible for property losses and often put human lives at risk. The floods are caused by coastal storms due
to the action of very strong winds. The propagation of these storms towards the coast induces high water
levels. Consequently, carrying out series of storm scenarios and analyzing their impacts through numerical
modelling is of prime interest to the coastal decision-makers. A contribution to the preservation and
sustainability of the coastal zone constitutes the main aim of this work. Firstly, historical storm tracks and
intensities are characterized for the Portuguese coast, in terms of probability of occurrence. Secondly, several
storm events with high potential of occurrence are generated using the specific tool DelftDashboard. The
hydrodynamic model Delft3D is then used to simulate their effects on currents and on the coastal water levels.
Two spatial domains are considered: a large domain encompassing the Iberian coastal zone and a smaller
domain for the central region of the Portuguese coast (between cities of Aveiro and Figueira da Foz); this one
with a more refined grid. Based on statistical data and by numerical modelling, a review of the impact of
coastal storms to different locations within the study area is performed.

Coastal ecosystems are greatly affected by human activities of environmental concern and public interest. The
increasing anthropogenic load of trace elements in coastal ecosystems is one of the most important inputs of
allochthonous matter into the oceans throughout river discharge in the estuarine ocean-river mixing zone. As
consequence of these mixing processes, estuaries are often considered as filters of the river signal inputs into
the ocean. Several studies describe estuaries as efficient filters of suspended particulate matter (SPM) and
heavy metals, majorly through particle-solute interactions, flocculation processes and settle down of metalcharged particles. In the other hand there also inverse processes such as re-suspension of riverbed
sediments, desorption of metals from SPM and sediments and diffusion processes between sediment
porewater and the overlying layer. As consequence of such a complex network of mechanisms, heavy metals
tend to show what is called a conservative or non-conservative behaviour, depending on the factors (physical
or chemical) that affect their distribution. These heavy metal charged particles behave as Lagrangean particles
and thus are highly affected by hydrological features. In the present work the behaviour of metal contaminated
SPM during spring and neap high and low tides is investigated using a MOHID 2D model in order to forecast
their pathways and destination on the estuary and thus its implications for the adjacent ocean waters and its
water quality under the MSFD framework.

Geomorphic control of an eroding ebb-tidal delta over the decadal evolution of an updrift coast after
jetty construction

Corresponding author: [email protected] (E Garel)
The response of an ebb-tidal delta and (1600 m-long) updrift beach to jetty construction at the entrance of an
estuary (Guadiana, southern Portugal) is examined based on bathymetric maps and aerial photographs
spanning six decades. Jetty construction (in 1972-74) induced strong erosion of the western delta until 1986,
together with rapid growing and seaward migration of the newly developed ebb shoal proper. Large beach
accretion resulted from the attachment to the coast (in 1985) of a shoal produced by the old delta erosion. This
85
indicates that cross-shore transport contributed significantly to jetty sand impoundment. After this erosive
phase, the individualization of an updrift lateral bar migrating seaward was promoted by the reworking of
sediment from the old delta. From 1996 onwards, this bar was attached to the nearshore and increasingly
disconnected from the jetty, suggesting that it now constitutes the main pathway for sand to bypass the jetty.
Accordingly, this period corresponds to a stabilization of the updrift beach position. This study demonstrates
that the response of updrift coasts (and related sediment bypassing process) to jetty construction at tidal inlets
may be affected by the geomorphic response of the ebb delta over decades.

Combined tidal and wind driven flow with residual currents: comparisons with field measurements
Holmedal LE, Wang H

Corresponding author: [email protected] (LE Holmedal)
The gravity forces from the Moon and the Sun, in conjunction with the Earth's rotation, induce tidal boundary
layers, which are important for phenomena such as transport of pollutants and biological material (e.g. fish
larvae and plankton), sediment transport and vertical mixing. For intermediate and shallow water depths the
tidal boundary layer occupies a large part of the water column, and a turbulence closure is necessary to obtain
a good agreement with measurements. Our tidal model has been validated previously against field
measurements. In these measurements, where wind was blowing over the ocean surface, residual currents
were detected. These residual currents reveal the presence of a small tidal drift in the ocean. By accounting for
the residual current and the wind stress in the tidal model, a fair agreement between numerical simulations and
field measurements is obtained. It appears that there are two different mechanisms responsible for this tidal
drift: residual currents and the surface wind stress. A detailed investigation of the tidal drift observed in the field
measurements, using our tidal model, will be presented in this work.

Climate change effects in physical ocean conditions (e.g. temperature) consequently result in change in
patterns of marine species. Global studies on how temperature changes have been performed in several
articles. However, studies in smaller regions are still few. In addition, temperature varies naturally across a
range of geographic and temporal scales. In this study, we observed change of sea surface temperature (SST)
in three Large Marine Ecosystems (LMEs): Canary current, Iberian coastal and Celtic-Biscay Shelf. We then
explored the recent version AVHRR SST dataset (Pathfinder 5.2) from NOAA polar-orbiting satellite, at day
time and night time from 1982 - 2011. We introduced Geographic Information System as tool in observing SST
change by ecosystem and by latitude degree. The results present explicitly the magnitude and differences of
sea surface temperature changes among ecosystems and latitudes. The results also show the difference of
observation between day time and night time. We expect that this approach and results can bring a better
understanding of sea surface temperature change in the three ecosystems and furthermore contribute in the
comprehension of species distribution studies as well as management and conservation strategies.

It has been suggested that climate change may be behind the strengthening of the patterns that cause
upwelling. Although the core of the Chilean coastal upwelling comprises from 18-42° S, our study area (40-42°
S) presents zonal upwelling events and is poorly documented. Thus, it is crucial to investigate the role that
climate change may be playing in the changes of spatial patterns of coastal upwelling in the southern sector of
the marine ecosystem as it is an ecologically fragile border and subject to strong anthropogenic pressures.
Long historical data series are needed, and thus to estimate climate variables for the past 60 years (19502010) we use data from the NCEP/NCAR to derive the following variables: wind direction and wind speed (m/s)
86
with daily resolution, in addition to the synoptic pattern. Also, we used MODIS satellite images to study the sea
surface temperature and chlorophyll - a between 2002 and 2012, at 4 km of spatial resolution. Our goal is to
study the relationships between oceanic variables (sea temperature and chlorophyll - a) and climatic variables
(wind and synoptic situation) to determine possible effects that climate change is causing in coastal upwelling
of the marine ecosystem.

Light penetration in the water column is a key environmental variable which is used by photosynthetic
organisms (phytoplankton and microphytobenthos). It is controlled by the amount and type of dissolved and
suspended materials in the water. Over the time, changes in coastal systems geomorphology have been
attributed to Sea Level Rise (SLR) and to variations in the amount of dissolved and non-dissolved matter.
Changes in the amount of light in water column are also expected, influencing the functioning of healthy
ecosystems. In this work, the light extinction coefficient in Ria de Aveiro (Portugal) is analyzed and computed
through an equation that relates the water absorption of radiation with the cohesive sediment concentration.
This concentration is predicted by a high resolution circulation model, under both present mean sea level and a
future SLR scenario. The maximum values of light extinction coefficient are found at upstream areas during
ebb conditions, while minimum values are observed near the inlet under flood conditions, revealing the higher
light penetration in seawater when compared to fluvial waters. When considering a SLR, a decrease in the light
extinction coefficient is predicted for the overall study area, due to the higher intrusion of marine water scarce
of sediments.

Topographic surveys and hydrodynamic measurements were conducted in a macrotidal beach located on the
Amazon coast of Brazil. Equinoctial and non equinoctial conditions were studied during dry and rainy seasons
to determine changes in beach morphology. Princesa beach is a gently-sloping sandy beach (1-2º) formed by
an elongated sandy ridge 200-400 m wide (between low and high spring tide water levels). It is composed of
fine sand (2.75 to 2.81 F). The largest tidal ranges were recorded during the equinoctial spring tides (> 5.0 m),
whereas the lowest range was recorded in June (4.3 m). The highest current speeds were observed during
flood tides due to the tidal asymmetry with maximal speeds (up to 0.8 m/s) recorded in November (strong wind
and reduced fluvial discharge) and equinoctial periods. An opposite pattern was found in June, when the wind
blew with lower intensities. Maximum and minimal waves Hs were found in March (equinoctial period - rainy
season) ranging between 0.1 m (low tides) and 1.3 m (high tides). The obtained results showed how the tidal
elevation and subtidal sandbanks modulate the wave energy during low tides. Ultradissipative and non-barred
dissipative characteristic predominated during the studied period.

We investigate the effect of the future sea level rise (SLR) on the propagation of tides in the Patagonian Shelf.
We run a numerical model for potential future SLR scenarios of 1, 2 and 10 m. The effect of flooding of lowlying land areas is also studied. Due to the morphological features and the sense of propagation of tidal waves,
inundation does not significantly modify the solution in the Patagonian Shelf; nevertheless, in the Northern
87
Argentinean Shelf dissipation is increased and results change. M2 amplitude responds to SLR in a spatially
non uniform and non linear manner. Tidal dissipation by bottom friction increases by 16% for the more extreme
scenario due to the increment of tidal amplitudes and currents over the Patagonian Shelf. Results suggest that
changes in the extension and position of the tidal fronts will be significant, with a reduction/increase of the
mixed areas in Southern/Northern Patagonia. The physical mechanisms for the modifications are changes of
the tidal wave speed, the Rossby radius of deformation, the energy dissipation by bottom friction and the
resonant properties of the basin. Similarly to studies performed for other coastal areas of the world, results
indicate that important changes in the characteristics of the tides can occur if the SLR is large.

Recent improvements in satellite altimetry data correction terms are encouraging studies of the remote sensed
Sea Surface Height (SSH) progressively closer to the coast and over shallow continental shelves. In this paper
we describe and discuss the SSH trend and variability at seasonal and interannual time scales in the South
American continental shelf influenced by the Río de la Plata estuary and the Patos Lagoon fresh waters. The
spatio-temporal coverage of the gridded altimetry SSH data allows to identify several variability patterns in the
region and the associated physical processes. On seasonal time scales, the combination of the solar radiation
and wind forcing cycles accounts for up to 98% of the variability. Seasonal variability in winds is responsible for
a difference of up to 20 cm between the southern (Argentinean) Río de la Plata estuary coast and the
Uruguayan and southern Brazilian coasts. On interannual time scales, positive/negative SSH anomalies are
highly correlated with El Niño/La Niña events. Finally, a significant positive trend of up to 5 mm/yr is found in all
the study area except in the region around the Patos Lagoon (Brazil) and part of the Río de la Plata. Besides
the local relevance of the results, this study indicates that satellite altimetry data are accurate enough to unveil
SSH spatio-temporal patterns close to the coast and over continental shelves in the mentioned time scales.

Vila dos Pescadores is situated on a coastal island in the Amazon coast and is bordered by a series of natural
environments, including dune, estuary and mangrove forest. This beach is under coastal processes (currents
and waves) and riverine influence. To understand the influence of the local hydrodynamic pattern on beach
morphology in this Amazon coastal area, two field campaigns were conducted during spring tides: (i) solistitial
period (June 2012) and equinoctial period (September 2012). Vila dos Pescadores is located in a macrotidal
area with tide ranges between 4 and 6 m and exposed to waves with Hs above 0.5 m and Tp between 2 and
8s. Local current tidal speeds vary from 0.5 to 1 m/s. In addition, they are characterized by a low gradient
(around 1°), fine and very fine sand (2.65-3.04 F), and an intertidal width of up to 1200 m at spring tides. The
local waves are modulated over the sandbanks between high and low tides, resulting in a bimodal wave height
distribution. This means that this beach is partially sheltered during low tides receiving lower wave heights and
shorter wave period. The highest energy condition was recorded in September and tide-dominated forces have
been contributing to the tide-dominated tidal flat characteristic.

Oceanographic processes operating in Amazon coast are a result of the superposition of several dominant
forces (e.g., macrotides, moderate wave energy, strong currents, elevated fluvial discharge) that are
responsible for continuous changes in beach morphology. The aim of this study was to understand the
changes in beach morphology related to parameters such as tidal range, breaker height, wave period, and
88
sediment fall velocity. The study took place at Ajuruteua beach during dry and rainy seasons. This beach is
composed of fine sand (2.6-2.8 F). During low tide, the intertidal zone is wide (200-300 m) and flat (around 1º).
Local tides are semidiurnal and asymmetric, with a longer ebb tide (6.5 to 7.5 h) and spring tides normally
reaching heights between 4 and 6 m. Circulation patterns are dominated by tidal currents, with speeds of up to
0.7 m/s. Significant wave heights reach minimum values (around zero) during the low tide, but exceed 1.5 m
during the high tide. Thus, this beach is sheltered by sandbanks during part of the ebb/low tides. As a result,
tide dominated tidal flat condition occurs during the least energetic hydrodynamic pattern, whereas during
major hydrodynamic events it is dominated by ultra-dissipative characteristic.

Heavy metals were monitored in surface sediment from an estuary, the Golden Horn, Istanbul. This urban
estuary has 3 distinct water masses; a very thin freshwater mass, brackish Black Sea water and more saline
Mediterranean water. Rapid urban growth and uncontrolled industrial development (1950-1985), however, led
to tremendous pollution of its water and thick layers of anoxic sediments. Due to ecologically unlivable
conditions it became the main subject of many top priority larger and smaller projects. However, these changes
remained far from initiating a large-scale transformation in the area. At the end of 2012 the municipality started
to transport Black Sea’s clean but more saline (17 psu) water to the Golden Horn through a 14 km tunnel. This
makes surface water denser, easily carrying suspended particulates much farther from the tributaries. As
sedimentation is a continuous process, the sediment bed is probably the best medium to store records about
the pollution history. In order to assess the sediment quality and to highlight the anthropogenic contributions to
heavy metal distributions, selected heavy metals in surface sediments were studied in 2012 and 2013. Multiple
chemometric approaches indicated three different regions along the estuary and revealed natural and
anthropogenic sources with moderate levels of Cu, Zn, Pb and Cd. Mitigation measures conducted at the
estuary affect transport processes but not all over the estuary.

The Asian clam Corbicula fluminea is one of the most pervasive aquatic invasive species worldwide. C.
fluminea reach high densities and may change key ecosystem processes. We evaluated the effect of C.
fluminea on key N-biogeochemical pathways in an estuarine ecosystem. Thirty six microcosms were deployed
subtidally, in a combination of 3 C. fluminea densities (0, 1000 and 3000 ind.m-2) and 2 types of sediment
(gravel, mud). Four weeks after deployment, the microcosms were collected to determine the fluxes of
inorganic nutrients, nitrification and denitrification rates. High C. fluminea densities promote the release of

ammonia and nitrites to the water (1.8 ± 0.9 µmol NH4 m .h , 12.4 ± 0.8 µmol NO2 m .h ), and the uptake of

consequently higher magnitudes of denitrification and/or anammox. Thus, it is likely that C. fluminea alters the
sediment-water N fluxes in highly invaded estuaries, affecting both benthic and pelagic environments. Ongoing
research will unveil the microbial diversity associated with the processes studied in this work.

Mercury is one of the major contaminants due to its toxicity and easy bioaccumulates in aquatic systems. The
Tagus estuary has been contaminated by mercury from an inoperative industrial plant in Barreiro and an
operative chloralkali industry in Cala Norte. To better understand Hg distribution in intertidal sediments,
sampling campaigns were done covering these contaminated areas and two uncontaminated areas (Alcochete
and Vale Frades), during 2010/2011. HgT was analyzed in solid fraction. Pore-waters were separated from
sediment cores and analyzed for total and reactive mercury (HgT and HgR). The averaged [HgT] in sediments
-1
showed that Barreiro is the most contaminated site (24.2 ng g ), due to historical industrial activity. Sediments
-1
in Cala Norte presented higher average HgT values (7.2 ng g ) in the first 10-cm depth than in Barreiro (3.8 ng

g ), which may be related to the permanent operational chloroalkaly plant. The uncontaminated sites showed
-1
similar average [HgT] (0,50 ng g ) between them and 25 to 45 times lower than contaminated sites, as the
same trend was observed for HgT and HgR in the dissolved fraction. Results point to the existence of two Hg
hotspots, probably acting as the main Hg sources to the Tagus estuary.

Taperaçu is an Amazon estuary relatively shallow, has no direct fluvial discharge and is characterized by high
hydrodynamic energy. The present study examined spatial-temporal fluctuations in hydrodynamic and
hydrological variables in this estuary. Five campaigns were conducted during neap tides, between June/2012
and June/2013. Samples were collected at surface and bottom every three hours over a 25-hour period in
three stations located in the lower, middle, and upper sectors of the estuary. The temperature of the water
ranged from 24.4 to 32°C. Salinity was lower (minimal of 2.8) and turbidity was higher (maximal of 107.36
UNT) in the rainy season. The highest levels of dissolved oxygen were recorded in the lower sector (8.64 mg/l)
due to the highest hydrodynamic energy in this sector, increasing the exchange of oxygen in the water-air
interface. During the dry season, low turbidity (11.41 UNT) lead to high concentrations of chlorophyll-a (around
3
100 mg/m ), especially in the upper sector. High concentrations of dissolved nutrients (nitrite 0.14 µmol/l;
nitrate 14.09 µmol/l; silicate 106.31 µmol/l; phosphate 0.974 µmol/l) were recorded during the rainy season,
leading to phytoplankton blooms development. All variables were influenced by rainfall oscillations and by the
distance from the mouth of the estuary.

Metal pollution is typical within harbors and marinas, appearing in the form of antifouling paints, industrial
waste and other anthropogenic sources. The most modern marine antifouling paints contain a copper based
biocidal pigment and are applied to ship hulls and several other fixed structures (e.g. pilings, pontoons, buoys)
to stop the growth of fouling organisms. Although copper is the major constituent of these coatings, also other
heavy metals (e.g. Zn, Ni) appear in significant concentrations in anti-fouling paints. Recently become evident
that microplastics are also highly abundant in these sites, inherent to the human activities there developed.
Although typically characterized as different types of pollution agents, heavy metals and microplastics show
91
clear interactions with implications for the marine life of the surrounding environment. Anti-fouling paints are
known to release heavy metals to the water column by paint deterioration and consequent diffusion.
Microplastics are mostly composed by organic polymers being highly attractive molecules for heavy metal
binding. In the present work the release of heavy metals from different anti-fouling paints and consequent
binding to microplastic particles is discussed as another form of transport of heavy metals to the food chain.

Salt marshes are highly productive wetlands, which represent an interface between freshwater/terrestrial
ecosystems and marine systems. The availability of nutrients in a salt marsh is directly related to salt marsh
biological productivity. Although nitrogen has become a major concern for wetlands scientists dealing with
eutrophication problems, phosphorous also represents a key element to be evaluated as well as its
biogeochemical cycling. The microbial communities are a central component of trophic dynamics and
biogeochemical processes on coastal systems, since most of the processes in sediments are mediated by
microorganisms and carried out by enzymes. Salt marshes daily receive large inputs of allochthonous matter
during tidal flooding, depositing and interacting with its sediment. Sediment extracellular phosphatases are key
players in the decomposition process of this phosphorous-rich organic matter, being very active in all kind of
sediments due to its pH-isoforms. Although acid phosphatase is the most abundant enzymatic form, also
alkaline and neutral phosphatase can be found along a pH gradient in salt marsh sediments. If a deeper look to
the P-biogeochemistry is taken, evident changes in this element speciation can be observed and directly
connected to the activity of P-related extracellular enzymes. In the present work, this connectivity is
investigated in order to understand the role of microbes shaping phosphorus speciation and thus the
ecosystem P retention capacity as a valuable service provided.

Corresponding author: [email protected] (C Gonçalves)
Nitrous oxide (N2O), the third most important greenhouse gas, is of emerging environmental concern.
Estuaries are considerable contributors to tropospheric N2O but current emission estimates are uncertain due
to limited data available and variability of fluxes. To date, there are no known data on N2O levels in Minho and
Lima estuaries. In this work we analyse N2O variability and potential sources and estimate the respective
-1
fluxes in these estuaries. In Lima N2O attained concentrations up to 20.0 nmol.L at salinity zero and Lima
River was, apparently, the main N2O source for the estuary. In Minho N2O reached a maximum of 14.4 nmol.L
1
at salinity 2.3 and nitrification was likely to contribute for the enhancement of N2O in the estuary. In fact, the
+
relatively high concentrations of NH4 in Minho River and the correlations found between N2O and NO3 +NO2
(positive) and O2 (negative) can be interpreted as in situ N2O production through pelagic nitrification. Minho
and Lima surface waters were always N2O supersaturated (101-228%) indicating the estuaries constitute
-2 -1
potential sources of atmospheric N2O. Estimated mean N2O fluxes were 5.0 µmol.m .d (FC96) in Lima and
-2 -1
-1
4.1 µmol.m .d (FC96) in Minho estuary, corresponding to emissions (0.28-0.96 Mg N-N2O yr ) that represent
a reduced fraction (<0.01-0.02%) of global emission from European estuaries.

Spatial and temporal variations of the percentage saturation of dissolved oxygen (DO) were investigated from
1998 to 2008 along the salinity gradient of the estuary of Urdaibai (Bay of Biscay), to assess the effect of
hydro-climatic factors and chlorophyll a on DO. The longitudinal distribution of DO showed an inner to outer
92
estuary increase. Bottom waters had higher DO values than above, except in the outer estuary, where the
water column was well mixed and DO values did not vary significantly with depth. In the intermediate and inner
estuary, seasonal variations of DO were best explained by river discharge and related factors, such as rainfall
and salinity stratification, and to a lesser extent by factors such as chlorophyll a and temperature. At the outer
estuary seasonal variations of DO were small and DO dynamics were governed mainly by tidal exchange and
turbulence. At the inter-annual time scale, stratification index was negatively correlated with DO at the outer
two salinity zones, but at the intermediate and inner salinity zones, river discharge and chlorophyll a were the
factors that best explained variations. At this inter-annual time scale, unlike at the seasonal scale, temperature
did not show a significant relationship with DO.

points situated closest to the river outlets to the Baltic Sea, collected within surface water monitoring program

general trend was towards the improvement of water quality; this can be attributed to the changes in
agricultural policy and wastewater management, implemented over the study period in the drainage area of

The study was carried out in July 2013 in the Kongsfjorden and Hornsund fjord, at the western coast of the
Spitsbergen. The West Spitsbergen Current (WSC) has a strong Atlantic character and brings warm and
nutrient-rich water to the Kongsfjorden. However, the Hornsund fjord is under the strong influence of cold water
from the Barents Sea. The phycobilins (phycocyanin-PC and phycoerythrin-PE) are a family of hydrophilic

communities was assessed in three temperate salt marshes with different pollution loads. Denitrification
-1 -1
potential showed a strong temporal variation from 0.41 to 26 nmol N2.g wet sed .h , with higher rates in
summer and fall, indicating a possible temperature effect. Rates of N2O accumulation varied between 0.024
-1 -1
and 4.8 nmol N2.g wet sed .h with clearly lower rates in uncolonized sediments, compared with plants
colonized sediments, suggesting that plants promote higher N2O emissions. Potential denitrification rates and
N2O accumulation were also found to be correlated to the concentration of metals in sediments. DGGE profiles
of narG, nirK and nosZ differentiated denitrifier assemblages among the marshes. Quantitative qPCR data
clearly showed higher nirS copy numbers relatively to nirk, and that nirK copy numbers were positively
correlated to denitrification rates. Owing to the importance of salt marshes in biochemical processes, namely
on denitrification, the impact of metal contamination and the presence or absence of salt marsh plants on
shaping the denitrifier community in salt marshes should be considered during recovery and mitigation
strategies for those ecosystems.

Petroleum compounds represent a major environmental problem. However, the suggestion that these
contaminants can directly affect essential biogeochemical processes has rarely been considered. This study
examined the effect of petroleum in the two microbial mediated processes of nitrogen removal: anammox and
denitrification. Controlled laboratory experiments were performed using sediment slurries from an estuary in
the Northwest of Portugal. Rates were measured in treatments with and without crude oil amendments using

N-labeled NO3 and NH4 . The production of N2 and N2 was quantified by membrane inlet mass
spectrometry. Results revealed an antagonistic effect of petroleum in key microbial mediated nitrogen
processes. While denitrification was found to be stimulated under crude oil treatments, anammox activity was
clearly inhibited or completely disrupted by the addition of petroleum. These findings indicate that hydrocarbon
compounds may affect denitrification and anammox communities in very different ways due to the distinct
metabolisms of these two biological nitrogen removal processes. This study represents one of the first
contributions to the understanding of denitrification and anammox ecology in systems impacted with petroleum
compounds, with profound implications for the management of aquatic ecosystems regarding eutrophication

Biogeochemistry of methylmercury (MeHg) in sediments is not completely understood, regarding seasonal and
spatial variations within estuaries. Historical mercury (Hg) contamination in Tagus estuary is known but MeHg
variability is poorly documented. Here, seasonality of MeHg is assessed in pore waters for the first time and in
solid sediments from two highly contaminated sites (CN and BRR) and two with low to moderate Hg
contamination (ALC and VF), contextualized with other relevant environmental parameters. Seasonally
retrieved cores indicate that MeHg concentrations generally increase in pore waters with the exception of VF
site. Respectively, winter and summer periods account to a maximum amount MeHg/HgT of 20% and 43% in
CN, 15% and 86% in BRR, 18% and 95% in ALC and 60% to 25% in VF. On the other hand, few significant
correlations (p<0.05) were found for MeHg in the dissolved phase during summer contrarily to the winter
94
period. Despite MeHg/HgT being always less than 1% in solid fraction, more significant correlations (p<0.05)
were found suggesting a close relation with particulate organic carbon. Seasonality, spatial variability and Hg
partition associated with methylation in sediments pose different MeHg loadings in the different study sites,
potentially contributing with MeHg to the water column.

The multivariate statistical technique of Principal Component Analysis (PCA) was applied in this work to study
interrelationships of sediment parameters and metal speciation data (Hg and MeHg), as well as spatial
variations in different sites from Tagus estuary (CN, BRR, ALC and VF). Data pre-treatment and descriptive
statistics allowed the interpretation of factors accounting for different patterns of distribution. Screeplots and
cumulative percentage of variance as well as factor and score loadings are presented using different data pretreatment techniques. Analysis were carried out for solid fraction, pore-water and a combination of both. Based
on overall results, approximately 80% of data variance is explained in general by three factors in the Tagus
estuary. The prominent factor accounted in average for more than 45% of the total variation, generally
accompanied with other two factors. Methylmercury, both in dissolved and solid fractions, is one of the factors
accounting for data variance, particularly in CN case. Other factors may have effects in sediments from Tagus
estuary, one should comprise mineralogy and grain size, which were not taken into account. Although
seasonality, anthropogenic versus natural sources, salinity and climacteric conditions at sampling time may
contribute to mask results trends, this PCA allows to discriminate their impact on the system.

Tidal marshes are well recognized as potential sources of atmospheric hazardous substances, like CH3Br. A
sediment core from a salt marsh in northern Portugal (Caminha) has been used to reconstruct bromine inputs
and its behaviour (sink/source) over the last ca. 1700 years. The results suggest that this marsh has been a
net sink of Br during the Grand Solar Minima (Wolf, Spörer, Maunder and Dalton), a period of lower irradiance
and temperature, higher cloudiness and albedo. It is postulated that this climatic period likely weakened the
th
biologically driven emissions of Br, as CH3Br, from the marsh to the atmosphere. During the 20 century, the
Br content variability in sediments appears to also reflect anthropogenic sources. These are probably related
with the rise, massive consumption and prohibition of leaded gasoline (1920s-2000s) and the wide use of
organobromine compounds in agriculture and industry (1945 and afterwards). All these products are being
phased-out since the inception of the 1992 Montreal Protocol. Despite this, the Caminha tidal marsh sediments
only showed a decrease of Br concentrations after 2002. In the present scenario of climatic warming we
consider that it is meaningful to improve the understanding about the potential of Br as climatic change proxy.

Gorringe Bank, located ~270 km off Cape São Vincente (SW Portugal), as two shallow summits, Gettysburg
and Ormonde. This submarine mountain constitutes an excellent system to study local aspects of the northeast Atlantic carbonate system. For the surveys carried out in autumn 2011 and summer 2012, results show
that pH varied from 8.05 to 8.29, with the lowest values recorded for Ormonde peak in autumn. By contrast,
highest values of average Total Alkalinity (TA) (up to 2992 µmol/kg) were recorded at Ormonde, for both
seasons. Dissolved Inorganic Carbon follows TA trends. This spatial variability is eventually attributed to the
old alkaline lavas that occur on the top of Ormonde peak. Further, phytoplankton composition, in particular the
95
dominance of coccolithophores in Ormonde, may also have induced the TA increase. Gorringe Bank waters
were undersaturated of CO2 with respect to the atmosphere, except at Ormonde in autumn. Such seasonal
shifts are in part explained by processes of precipitation/dissolution of CaCO3 coupled to photosynthesis. Since
Gorringe Bank is on the way to becoming a new Marine Protected Area, following the nomination by the
Portuguese Government, this study aims to contribute for a scientific based management of the respective
bank in order to balance future exploitation and conservation.

The aim of this study was to understand the variation in hydrodynamic and hydrological variables within the
Amazon estuary (Taperaçu-PA). Field campaigns were performed bimonthly during neap tides at three stations
(lower, middle, and upper estuarine sectors) between October, 2010 and December, 2011. Tidal cycle was
asymmetric with longer ebb tides and shorter flood tides. Tidal currents reached a maximum speed of 1.2 m/s
(October 2011). Water temperature was high and stable (27.0 and 30.0 ºC). Salinity varied substantially during
the study period (2 in rainy season to 38 in dry season). Local waters are well oxygenated, turbid, and present
high chlorophyll a and nutrient concentrations. Low hydrological variation was recorded between superficial
and deep water samples. Ammonia was the nitrogenated fraction preferred by the phytoplankton, and an
increase in primary biomass was observed when ammonia concentrations increased. As the Taperaçu estuary
is located within a substantial area of mangrove forest, this forest would be indicated as the principal source of
dissolved nutrients to the local system. In addition, the high nutrient and chlorophyll a concentrations are also a
result of the re-suspension processes by the strong tidal currents, mainly in October 2011 (influence of
equinoctial event).

A sedimentary core taken from Lagoon Kucukcekmece on the northern shoreline of the Sea of Marmara was
analyzed to delineate the vertical variations of organochlorine pesticide (OCPs) residues using gas
chromatography (GC-ECD/MS) and radioisotopically dated using 210Pb. The .25OCPs concentrations ranged
from 0.5 to 535.6 ng/g-dw, with the median concentration of 61 ng/g-dw of the 25 OCPs, a-HCH, p,p’-DDT and
aldrin dominated the OCPs, with the maximum concentrations of 469.3 ng/g, 71.0 ng/g and 20.5 µg/g-dw
respectively, and accounted for 64, 10 and 12% of the .25OCPs concentrations. Dated concentration-depth
profiles suggest that highest inputs occurred in the first half of the last century and were followed by significant
decreases. The major sources of the HCHs were from the use of technical HCHs. Sources DDTs identified by
specific molecular ratios indicated that DDT residues in Kucukcekmece Lagoon were mainly originated from
technical DDTs from both historical usage and recent input. The organochlorine pesticide residues did
demonstrate markedly different distributions reflecting different agricultural and domestic usage in the region.
Therefore, this study on the residual levels of the OCPs, their temporal distributions and the source analysis
will not only contribute to understanding the environmental behavior but also provide the necessary theoretical
basis for persistent toxic pollution prevention and lake environmental management.

In shallow water ecosystems oxygen deficiency is less expected due to low depth and active hydrodynamics.
However, recent studies shows, that hypoxia can occur in the eutrophic or hypertrophic coastal lagoons during
96
the summer. Oxygen deficiency facilitates nitrogen and phosphorus accumulation in the bottom water layers.
It’s associated with change of redox conditions in sediments. These changes directly influence the bottom
macrofauna, and ratios between oxidized, reduced iron and manganese. In the presentation several
biogeochemical studies of different coastal lagoons Sacca di Goro (Italy) and the Curonian lagoon (Lithuania)
were considered. According to the existing studies, during summer (when riverine inflow is minimal) macro and
micro-algae can build a “self-sustaining system". It could be described as a sequence of processes: increased
accumulation (due to the algal bloom) of organic matter in sediments increase oxygen consumption. hypoxia in
sediments .increased phosphorus release in bottom water . intensified algal blooms. By creating this “vicious
cycle”, the algae will start to consume nutrients released from the sediment. The aim of this study is to quantify
phosphorus and metal (Fe, Mn) release at the sediment–water interface in hypoxic conditions in different
coastal lagoons.

Dissolved organic carbon distribution along Cananéia-Iguape Estuarine-lagoon Complex (Brazil)
considering the natural and anthropogenic sources
Berbel GBB, Braga ES, Bertini LM
Instituto Oceanográfico, Universidade de São Paulo, São Paulo, Brazil
The estuarine-lagoon complex of Cananéia-Iguape (Brazil) could be considered by two aspects: i) north region
is influenced by Ribeira de Iguape river which receives inputs from human activities and is connected to the
estuarine system by an artificial channel - “Valo Grande”; ii) the south region, which is unpolluted and
classified as Biosphere Reserve by UNESCO. This study evaluated the dissolved organic carbon (DOC) in two
sectors described, in winter (2012) and summer 2013). No significant differences between surface and bottom
-1
concentrations were found in both sectors. The DOC concentrations varied from 0.82 to 3.11 mg.L in winter
-1
and 0.94 to 4.09 mg.L in summer. In winter, the highest values of DOC were located in the north region,
influenced by the river. In summer, the highest concentrations were found from middle to southern areas.
Naturally, the different sources of organic carbon at the region play an important role in the distribution along
the salinity decreasing gradient reinforced by human interference. The natural and anthropogenic carbon are
present in the system, with evident seasonal behavior. (INCT-TMCOcean-CNPq 573.601/2008-9 and CNPq

The Cananéia-Iguape estuarine lagoon complex is considered a nursery for several species. In the north of the
system, an artificial channel was constructed to connect the river water (Ribeira de Iguape river) to estuarine
water. In function of it the salinity of the north region reached 0 and the south part of the system remained with
salty waters. Some difference in biodiversity occurred and the nutrient ranges show also how big is the
modification in this system. At this moment the south part is preserved and considered a part of the Biosphere
Reserve (UNESCO). What is expected at this region? In summer 2013, the hydrological parameters were
measured and the ranges of nutrients were 0.02-0.13; 10.50-11.45µM; 0.09-0.13µM; 2.52-4.02µM; 3.175.13µM; 177.68-211-16µM in north sector (Iguape), 22.68-28.60; 0.12-0.50µM; 0.10-0.21µM; 1.29-2.11µM;
0.50-0.88µM; 11.78-39.13µM in south area (Cananéia) for salinity, nitrate, nitrite, ammonium, phosphate and
silicate, respectively. The increase of freshwater input in the system provoked by the human interference is
the essential factor of the biogeochemical changes in this region, with sensitive effects on the biota and

Arthrocnemum indicum is a perennial halophytic such a C3 shrub, distributed on coasts from Mediterranean
region, to the Middle East and Asia, can endure water floods and salinity. A better understanding of chlorophyll
fluorescence and pigment contents participation in salt tolerance of the studied halophyte is required. These
approaches leading to the production of transgenic salt tolerant are possible and so far the results obtained
with many genes are promising. However, in order to have great success in this respect it is required that
identification of uncovered tolerance traits and stress inducible promoters must be further explored. Plant
morphology and growth, chlorophyll fluorescence and pigment contents were studied in this species cultured
under arsenic stress and/or combined with salt stress conditions. Regarding pigment content the data indicate
that there’s an increase in all pigment concentration within increasing of trace metallic elements concentration
as augmentation on carotenoid contents, total chlorophyll and chlorophyll a and b. Despite these variations,
there’s no difference on photosynthetic parameters: dissipated, absorbed and transported energy flux or
performance index. All of them had the same fluctuation in all trace elements contents. All these aspects
suggest that Arthrocnemum indicum have a greater survival potential in salty condition.

Sandy beaches are natural dynamic ecosystems, which are becoming worldwide increasingly disturbed by
intensive human direct use, coastal development and erosive evolution. In this study, we have examined
whether ten years of potential increased human pressures have resulted in significant changes in the
macrofaunal assemblages’ structure and composition of two mesotidal sandy beaches (Cabedelo – urban
beach, and Quiaios – rural beach) on the European Atlantic coas. Seasonal macrofauna collections were
performed at both beaches in two different periods, one in 1999-2000 and another in 2010-2011. The physical
variables did not change significantly in both beaches throughout the studied periods, however, the urban
beach was subject to an increase of human pressures (tourism and shoreline modifications) over the 10-years
interval considered when compared with the rural beach. The univariate community descriptors (total density,
species richness and diversity) did not differ significantly among periods for the rural beach. In contrast,
temporal differences were found at the most urbanised beach, principally regarding the abundances of the
amphipod Talitrus saltator and the isopod Tylos europaeus, two of the most abundant species at both
beaches. PERMANOVA tests enhanced these temporal variations and the SIMPER analysis attributed to
these species the main differences found between periods in this beach. Since the physical environment was
similar in both periods, the ecological changes were most likely attributed to the increased human pressures
observed at the urban beach. Nevertheless, this study highlights the need of further robust and effective impact
assessments.

The Firth of Lorn is at the mouth of one of Scotland’s largest fjordic sea lochs, Loch Linnhe. This sea loch,
which is fed by a number of other inner lochs, supplies a significant flow of freshwater, which generally causes
the stratification of the water column. An intensive field campaign was conducted in September 2012, when the
water column was mixed, except in the most inner stations. Water samples were collected for nutrients and
phytoplankton (pigments and microscopy). Chemotaxonomy was used to estimate the contribution of different
taxonomic groups to total chlorophyll a. Generally, nitrogen concentrations were found to be low (< 3.5 µM).
The highest nitrogen concentrations were found in the most inner station (relatively rich in NH4) and in the most
offshore stations (rich in NO3+NO2). Centric diatoms, mainly Chaetoceros sp. and Skeletonema costatum,
were found to be associated with NH4 concentrations, while pennate diatoms, mainly Cylindrotheca sp.,
Navicula sp. and Nitzchia sp., were found to be associated with NO3+NO2. The highest levels of chlorophyll
-3
(~2.6 mg.m ) were found in the vicinity of Oban Bay, where dinoflagellates, and other flagellates, thrived in the
slightly stratified water column. The most abundant dinoflagellates, which were present in most samples, were
Gymnodinium-like cells.

The main objective of this paper was to evaluate the impact of mercury on the zooplankton communities'
structure and functioning and their bioaccumulation patterns along a contamination gradient in a temperate
coastal lagoon. Our results demonstrated that total abundance was not negatively affected by Hg
contamination, since the most contaminated areas presented the highest values, being the copepod Acartia
tonsa the dominant species, which means that it is a very well adapted and tolerant species to mercury.
Nevertheless, negative effects were observed in terms of species diversity, since the most contaminated areas
presented the lowest values of species richness, evenness and heterogeneity. Moreover, the spatial mercury
gradient was reflected on the bioaccumulation patterns of the zooplankton communities. This reinforces the
idea that zooplankton can be considered as an important vehicle of mercury transfer through the food pelagic
web since it constitutes a primordial food resource for several commercial fish species.

Patterns of biodiversity (alpha and beta), abundance and community structure of macrobenthic assemblages,
along a gradient of metal contamination, were investigated in the Tagus estuary. Two contaminated and two
reference areas were selected and at least two stations have been assigned to each one of these areas (nine
stations in total). At each station, three replicates were collected with a Van Veen grab on September 2012,
February, May and October 2013. From each replicate, sub-samples were taken for particle grain-size analysis
and metal concentrations. The results confirmed the existence of significantly higher levels of metals (Hg, Cd,
Pb) in contaminated areas compared with reference areas. No consistent spatial and temporal patterns were
detected for alpha- and beta-diversity. Alpha-diversity values (number of taxa and Hurlbert’s expected number
of taxa) were generally higher in contaminated areas and peaked in summer; beta-diversity patterns were
more variable in space and time and were highly measure-dependent, supporting the need to include multiple
measures in data analysis. The present results also showed that higher alpha-diversity does not necessarily
mirror higher complementarity, highlighting the importance of combining both components of diversity to shed
light on the patterns of change in assemblages along disturbance gradients.

The Venice Lagoon is characterized by many different shallow-water habitats, where salt marshes represent
one of the most important for many fish species, both resident and marine migrant. On the other side, in the
many small lagoon islands, artificial creeks of different size and morphology are present, once used in
traditional fishery activities or built up as defence lines. Aims of this study is to determine the ecological value
of the smaller creeks, both natural and artificial, for fish populations. One year samplings in four sites (two
natural salt marshes and two artificial creeks) allowed to describe the fish community inhabiting these sites,
which comprises 20 species overall. Influence of water parameters and habitat structure were considered in
analyzing the community patterns observed. In particular, some of these habitats hosted high abundances of
resident fish species listed in the Annex II of the Habitat Directive. Furthermore, juveniles of eight species of
marine migrant fish were found, some of which of economic importance. Therefore, results of these studies
underlined the ecological importance of these marginal habitats for many fish species, of both conservation
and economic importance.

Phytoplankton communities’ dynamics were studied in Salgados coastal lagoon in order to evaluate the effects
of excessive organic loads and also physical stress caused by the irregular opening of the lagoon. Salgados is
a hypereutrophic semi-enclosed coastal lagoon, which received freshwater inputs from small rivers and from a
wastewater treatment plant. Cyanophyceae dominated the phytoplankton communities most of the time;
Bacillariophyceae became the main taxonomic group in winter when the lagoon was closed; Chlorophyceae
was the major class in early summer; pico-nano flagellate algae accounted a high percentage of total
phytoplankton during spring. Potentially harmful taxa were observed during most of the sampling periods,
forming blooms and accounting for a considerable percentage of total phytoplankton abundance. A strong
differentiation among dry and wet seasons could be noticed. The dry season was dominated by Microcystis
aeruginosa, Rhodomonas sp., pico-nano flagellate algae, Cyclotella spp. and Planktothrix sp., while the wet
season, although still with the presence of Microcystis aeruginosa, was dominated by Anabaena spiroides. The
best environmental variables explaining stations patterns and based on phytoplankton taxa were days of
isolation, pH, and salinity. Temperature, cumulative rain and total phosphorus were also related with species
and stations patterns.

Benthic macroinvertebrate communities and environmental conditions were studied in two choked coastal
lagoons from Algarve (Foz de Almargem and Salgados), with the purpose of evaluating the effects of organic
pollution from wastewater discharges and the physical stress caused by the irregular opening of the lagoons.
Most of the year, lagoons were isolated from the sea receiving the freshwater inputs from small rivers and in
Salgados, also the effluents of a wastewater plant. According to environmental and biotic conditions, Foz de
Almargem presented a greater marine influence and a lower trophic state (mesotrophic) than Salgados
(hypereutrophic). Benthic macroinvertebrate communities in the lagoons were distinct, just as their relations
with environmental parameters. Mollusca were the most abundant macroinvertebrates in Foz de Almargem,
while Insecta, Oligochaeta and Crustacea were more relevant in Salgados. Differences in taxa densities were
associated to some environmental parameters of the lagoons, such as temperature, total dissolved inorganic
nitrogen, total phosphorus, chlorophyll a concentration in water, chlorophyll a concentration in sediment and
clay content. Both lagoons were dominated by deposit feeders and taxa tolerant to environmental stress,
although in Salgados there was a greater occurrence of opportunistic taxa associated with pronounced
unbalanced situations due to excess organic matter enrichment.

The Portuguese monitoring program of toxic phytoplankton carried out between 9 - 20 July 2013, revealed the
presence of D. acuminata in unusually high abundances at different sites in Lisbon bay and also in a coastal
lagoon located 40 km south of Lisbon, west coast of Portugal. Twelve years of toxic algae monitoring in these
areas showed that at Lisbon bay, an abundance of D. acuminata of the same order of magnitude as that
observed in 2013, only occurred in 2005. By contrast there are no records of such dense populations of this
species in Albufeira lagoon during this period. In both situations, the high densities of D. acuminata were
related with the relaxation of the summer northerly winds on the west coast, concomitant with exceptionally
high coastal temperatures. These conditions result in a strong convergence of oceanic water to the coast. In
fact, sea surface temperature rise up to more than 20 °C, (2 °C above average) in Setúbal and Lisbon bays. In
2013 this atypical summer convergence, was associated with persistent winds from southwest which led to a
warm poleward coastal current. We suggest that these oceanographic conditions favored the entrance of D.
acuminata in the lagoon, where stratification conditions, combined with less horizontal dispersion in the
confined water body, favored the population maintenance.

Benthic meiofauna and macrofauna constitute fundamental components of heterotrophic aquatic assemblages
by influencing carbon transfer through the food web, and represent an important link between primary
producers and higher trophic levels. However, these compartments are poorly known in the upper parts of tidal
estuaries, where the freshwater masses are submitted to tides. In the present study, meio- and macrofauna
communities were investigated in the tidal freshwater sections of the Gironde Estuary, i.e. in the 40-km lower
parts of the Garonne and Dordogne Rivers. Both rivers are characterized by a strong seasonal variability of
environmental parameters and are also submitted to anthropogenic pressures, mainly from the city of
Bordeaux on the Garonne. In both branches of the fluvial estuary, macrofauna (>1 mm) was composed
exclusively of Oligochaeta in intertidal areas, whereas it was totally absent in subtidal areas. Meiofauna was
mainly composed of Nematoda, Foraminifera and Copepoda in both subtidal and intertidal domains. MDS
analyses showed that meiofaunal community structure was highly modified between May and October in both
estuarine rivers but then returned to its initial stage. Abundance and composition of both benthic communities
were not impacted by the Bordeaux water treatment plant.

Nutrient availability is a key factor regulating phytoplankton growth and species composition. A comprehensive
understanding of how nutrients affect phytoplankton dynamics is therefore essential for eutrophication
mitigation and management. The Ria Formosa coastal lagoon is one of the most important and vulnerable
ecosystems in Portugal and it is subjected to strong anthropogenic pressures and natural nutrient inputs
associated to coastal upwelling. The aim of this study was to determine the effects of nutrient enrichment on
phytoplankton growth and species composition in the Ria Formosa, during the productive period. N, P and Si
were added to natural microcosms collected at the landward and seaward boundaries, in summer 2012.
Treatments were incubated in situ under two different light intensities. Phytoplankton composition, abundance
and biomass, growth rates and nutrient consumption were evaluated. Potential nutrient limitation by nitrogen
was observed. Nitrogen addition led to a significant increase in N consumption, resulting in higher
phytoplankton growth in all N-enriched treatments, under both light intensities, at the landward station.
Consumption of silica and phosphorus in the amended treatments was also significantly higher in relation to
101
the controls, but it was not reflected on phytoplankton growth, probably due to luxury consumption. The
seaward station was primarily limited by light and not nutrients.

Spartina versicolor (Ait.) Muhl. (Poaceae) is a perennial rhizomatous grass that grows in a wide range of
coastal habitats being endemic from North America, where it has been identified as Spartina patens. There are
some doubts on how this species has entered in the Mediterranean space. It is probable that the plant was
introduced first to various ports around the Mediterranean, as it was used as packing material in ships boxes
and crates. Being a strong rhizomatous invasive species, the presence of S. patens in NW Iberian salt
marshes could represent a considerable impact on the native plant communities. Recent data, showed a large
expansion of this species coverage area along almost all estuarine ecosystems on the western coast of
Portugal, invading the habitats of more sensible autochthonous species, such as Spartina maritima. In the
present work a seasonal monitoring of both endemic and alien species rhizosediment microbial activities will
be presented in order to understand the impact of this species on the organic matter cycling along a seasonal
cycle. This will allow to understand the impact of this invasor on the sediment functions while ecosystem
service provider while cycling the incoming organic matter.

Genus Spartina (Poaceae) includes several species that play a central role in salt-marsh sedimentary
dynamics. In Portugal, we have recently noticed the expansion of a Spartina species in places that are usually
exclusively inhabited by the native Spartina maritima. Molecular analyses indicated that this taxon is an
introduced genotype of S. patens, a perennial grass that grows in a wide range of the North-East American
coastal habitats. It’s likely that it was introduced into various Mediterranean ports (where similar plants are
known as S. versicolor), used as packing material in ship boxes. Being a strong rhizomatous invasive species,
the presence of S. patens in NW Iberian saltmarshes could represent a considerable impact on the native plant
communities. It now invades the habitats of more sensible autochthonous species, such as Spartina maritima.
A seasonal monitoring of both species was performed to understand the species photobiology along a climate
annual variation. Crossing this information with the species stable isotope signatures provided important data
on the species carbon and nitrogen sink role. This will allow gaining insight into the ecophysiological
mechanisms underlying the success of S. patens in European marshes, the reason of its high productivity and
the implications on the marsh biodiversity.

In estuaries, primary productivity is mostly driven by the photosynthetic carbon fixation by phytoplankton and
microphytobenthos. The estimation of ecosystem-level productivity budgets has been hampered by the lack of
i) an integrated assessment of pelagic and benthic photosynthetic activity, ii) sampling frequency matching the
relevant time scales of variability and iii) upscaling of local measurements considering the spatio-temporal
variability of tidal exposure and water column height. In this study, the integrated pelagic-benthic productivity of
the Ria de Aveiro, Portugal, was assessed from high frequency measurements of in vivo chlorophyll
fluorescence indices, measured together with physical parameters (salinity, temperature), and microalgal
biomass (chlorophyll a concentration). Measurements were carried out in situ, on intertidal flats and overlying
102
water column in three sampling sites representative of dominant habitats in terms of hydrodynamics and
sediment granulometry. Measurements were taken hourly during 12 h-tidal cycles, on spring and neap tides,
during four periods distributed during one year. Hourly rates of carbon fixation were estimated from
measurements of absolute rates of electron transport rate, based on absorption cross section and quantum
yield of PSII. Local, hourly productivity rates were upscaled to annual, ecosystem-level budgets using a
circulation model developed and validated for the Ria de Aveiro.

Hard coral diseases and injuries are increasing worldwide as a response to natural and anthropogenic impacts,
which affect the biodiversity and ecosystem function and services. The distribution of coral diseases and
injuries was investigated by random transects in 10 sites and at 3 depths (i.e. reef flat, crest and slope) around
Bangka Island (North Sulawesi, Indonesia) and each symptom was recorded by pictures. Benthic
assemblages, substrate and coral rubble were also recorded. For each site, information on anthropogenic
disturbance sources and previous impacts (e.g. oyster farm, blast fish) were collected. The most common
lesions were coral bleaching, galls due to tube formers, growth anomalies and signs of fish predation. Very few
occurrences of white syndrome, ulcerative white spots, skeletal eroding bands, brown bands e black bands
were found. Despite differences among sites, the largest number of lesions, especially coral bleaching and
growth anomalies, were found on the reef flats. In spite of past human impacts, the fringing reefs of the island
still appear healthy at different sites. Unfortunately, today the proposed mining activities threaten these coral
reefs at the centre of the coral triangle.

Phytoplankton elemental composition constitutes a direct measurement of environmental changes, allowing
anticipating consequences of anthropogenic alterations to organisms, ecosystems and global marine
geochemical cycles. Traditional bulk size-fractionation techniques used to measure phytoplankton elemental
composition may present ambiguous results due to considerable detrital matter occurrence. Alternatively,
nuclear microprobe techniques are a powerful tool, allowing qualitative imaging of distribution, and quantitative
determination of intracellular concentrations. To our knowledge, this is the first study aimed at evaluating metal
content and compartmentalization changes in whole diatom (Coscinodiscus eccentricus) cells exposed to
different metal loads. Cells exposed to Ni, Cu and Zn, were analysed with particle induced X-ray emission
(PIXE), Rutherford backscattering spectrometry (RBS), and scanning transmission ion microscopy (STIM)
providing simultaneous assessment of cell morphology and elemental concentration distribution. Diatoms
clearly responded to environmental alterations, by changing cytoplasm morphology, concentrating added
metals, and altering Fe transport mechanisms. Different metal accumulation patterns indicated higher
susceptibility to Cu, retained in cytoplasm, than to Ni and Zn, mobilized to the vacuole. Metal mapping gave
clues about metal transport, toxicity, and fate in the ecosystem. These aspects highlight the value of diatoms
as biomonitors of environmental quality and allowed estimating consequences of metal pollution in marine
biogeochemical cycles.

Rangia cuneata was recorded in the Vistula Lagoon in September 2010. Clams were collected at a station
(54°40.19' N, 20°00.85' E) where Atlantic rangia were most abundant. From April 2011 to November 2012, four
replicate samples were taken monthly. Somatic production (Ps) was calculated according to Boysen-Jensen
method. Average assimilation efficiency was 0.7 for suspension-feeding bivalves. In 2011 and 2012, the Ps

values were on the same level (607 and 604 kJ.m .year ). In 2011 respiration (R) and consumption (C) were

lower by 2 times (5,709 and 9,023 kJ.m .year ) than in 2012 (11,711 and 17,593 kJ.m .year ). In 2011, P/B
ratio and net production efficiency (K2) were 1.76 and 0.096, and decreased to 0.91 and 0.049 in 2012. In
2011 and 2012, the annual primary production (Pp) were 19,000 and 24,400 kJ•m-2•year-1. Clams might to
consume 47% and 72% from Pp (C/Pp) in 2011 and 2012. Until 2010, zooplankton was main the consumer of

phytoplankton. Consumption of zooplankton averaged 970 kJ.m .year or 7% from Pp. Water clarity increased
with 0.59-0.74 m in 1995-2010 to 0.84 and 0.99 m in 2011 and 2012. Thus, clams become the important
component of the Vistula Lagoon ecosystem and play a significant role in water self-purification and
clarification.

Conservation science increasingly focuses on how ecosystem functioning is affected by anthropogenic
pressures, which implies an understanding about the structural and functional changes in biological
assemblages and requires indicators to timely detect such changes. A novel approach was used to model the
response of several fish-based metrics to gradients of trawling. The response of these metrics to increasing
intensity of fishing revealed a significant biomass loss with a corresponding increase of dominant species.
Additionally, in the most fished areas there were noteworthy changes in vulnerable features of fish
assemblages like biomass of chondricthyes as well as very low-resilient species and those more sedentary.
These patterns were attributed to direct and indirect fishing effects acting synergistically over specific features
of fish assemblages leading to its homogenization. Moreover, different critical thresholds were identified,
depending on the nature of metrics, suggesting that it is difficult to define a single global target for fishing
management as it ultimately will depend on management and conservation objectives. Overall, this study
suggests that fishing can affect the functioning of fish assemblages and could consequently change the
resilience of marine ecosystems, therefore, research that focus on the use of indicators as warning tools
deserves our better understanding.

“From an antagonistic to a synergistic predator prey perspective: Bifurcations in marine ecosystems" is the title
of a book that will be published by Elsevier in 2014. The book presents predator-prey synergism as a novel
perspective in ecology, defined as predator-prey relationships enhancing abundances of both predator and
prey. The idea emerged during analyses of near-century long time series of observations of marine coastal
ecosystems, but it is suggested that synergism may be important in some terrestrial systems too. Predatorprey synergism has wide-ranging implications for management of marine ecosystems and for theories in
ecology and evolution. Resilience in marine ecosystems may be explained mechanistically by synergism, as
may repeated incidents of bifurcations observed in the long time series. Bifurcations are sudden and persistent
regime shifts as a result of gradually changing environmental conditions. It is suggested that global warming
may induce bifurcations which in turn may result in recruitment failures in fishes and substantially reduced fish
abundances.

community with Mesopodopsis slabberi, Neomysis integer and Rhopalophthalmus tartessicus make up to over
80% of total macrofauna biomass in the estuary. Life history, population structure, secondary production,
trophic level and community spatio-temporal dynamic were unravelled combining analysis of long term 16y

trophic role in food web, a seasonal trend showing density peaks (23, 3 and 6 mg/m , respectively) in springsummer and winter marine coastward migration. Despite being euryhaline, the three species of showed

assemblage. Inter- and intra-specific euryhalinity differences both for prey and predators seem to determine
the entire spatial estuarine community distribution. High secondary production (P/B rates 38.2, 10.3 and 10.7)
and food web studies confirm key role of mysids transferring energy up to juveniles (fish and crustaceans)
arriving yearly in spring to their nursery area.

The Negro River Estuary is a micro to meso tidal influenced estuarine system in a semi arid region in North
Patagonia Argentina. The status of its quality waters has raised interest in the last years by increased uses,
urban, agriculture, fishing and nautical sports of international levels. Waters samples were taken from spring
2011 to autumn 2013 to determine microbiological transport among Guardia Mitre and Atlantic Ocean zone.
Total coliform, fecal and E. coli were examined by NMP per 100 ml in relation to environmental parameters and
point sources. The Pearson correlation was typically significant with temperature, and preliminaries results
revealed E. coli survived in winter months at low temperatures (maximum level of 93 NMP/100 ml) and had

Previous studies on feeding habits of European anchovy Engraulis encrasicolus, carried out in open sea,
described it as a strictly zooplanktivorous species, with copepods their main prey from larvae to adults.
Nevertheless the analysis of the stomach contents of a total of 1836 individuals (from 18 to 131 mm total
length) collected monthly (from February 1998 to January 1999) at the Guadalquivir estuary (SW Spain)
revealed that estuarine mysids play an important role in their diet. Inside the estuary, the smallest individuals
analysed (postlarvae) fed mainly on copepods, but as they grew into juveniles they shifted to mysisd. In fact,
estuarine mysids represented 76% of dietary composition, in terms of biomass, of juveniles (total length > 40
mm), being Mesopodopsis slabberi the main prey species (46%). During last 16 years, from June 1997 to date,
abundance of anchovy and mysids have been monitored by monthly sampling in the estuary. This time series
has pointed out the role of the estuary as an important nursery ground for anchovy. The seasonal coincidence
of maximal anchovy and mysid densities suggests that food availability may be a principal factor influencing
that nursery function.

Global climate change is affecting the dynamics of a wide variety of marine ecosystems. The increased
prevalence of invasive species is expected to have further deleterious effects on the biodiversity of native
ecosystems. This study reviews the causes of spreading of the widely distributed kelp Undaria pinnatifida and
predicts its global ranges for present and future times. This structuring species is native from the Western
Pacific and has recently expanded ranges to most temperate regions worldwide, mainly due to accidental
introductions by aquaculture and the ballast waters of cargo ships. Niche modelling was performed, relating
documented occurrences against environmental parameters (light, temperature and nutrients) to predict global
distribution under different proxies of climate. Results showed that this species’ ranges are mainly shaped by
temperature and that the global potential habitat for present-times is much greater than what is currently
realised. Dispersal mechanisms were inferred as the main limiting factor for the further spread of this kelp; the
consequences of future range dynamics of this kelp on local communities were also discussed. We
demonstrate the pressing need to assess the vectors for invasive spreading alongside with the potential impact
of new invasions resulting from shifts in climate niches.

Iberian Peninsula (IP) constitutes the northern sector of the Canary Current Upwelling System. This study
analyses the influence of upwelling on phytoplankton variability over a 15-year time series (1998-2012) off
southwestern IP. Three polygons were delimited within the study area: west (WC) and south (SC) coasts and
Cape São Vicente (CSV), the inflection point where coastline orientation changes. Phytoplankton descriptors
were chlorophyll-a concentration (Chl-a - SeaWiFS and MODIS) and primary production (PP - EppleyVertically Generalized Production Model) while two approaches, temperature and wind-based, were used to
infer upwelling patterns. Indices were derived from offshore-onshore difference of sea surface temperature
(UIT) and scatterometer-based Ekman transport (UIW). Most of the years, for both indices, a clear annual
cycle depicted summer as the most upwelling-favorable season. Conditions for upwelling were higher for WC
and CSV than SC. Chl-a monthly climatologies presented similar patterns for WC and CSV, with the lowest
values during winter and peaks in spring and summer. The highest Chl-a in SC was observed during early
spring. In respect to PP, all areas exhibited maximum values during summer and minimum in winter. Across
the time series, both Chl-a and PP were significantly correlated with both UI presenting seasonal-dependence
and area-specificity.

Human trampling originates a diffuse path network that is responsible for foredune habitat fragmentation. In
this study, the effects of patch area and isolation on the distribution patterns of foredune plant species and
communities were examined. The study was conducted in three foredune-sites at Vila Nova de Gaia (NorthWestern Atlantic coast of Portugal), with comparable total areas and similar proportion of vegetation cover, but
varying levels of fragmentation. Results suggest that patch area plays a fundamental role at the species level,
as it determines the occurrence of the majority of the studied species in a patch, whereas patch isolation
seems more important in explaining plant assemblage distribution patterns. Foredune plants have local, shortdistance dispersal (poor dispersal abilities), thus life form and dispersal type do not explain the clumpy
distribution of species at the landscape scale. These findings are consistent with the conclusion that species
extinction in a foredune habitat patch, due to its small size (area effects), is prevented by the proximity to other
patches of the same or similar habitat type, if a species is able to bridge the distance (path width), and
disperse successfully between patches of a certain neighbourhood or cluster (rescue-effect).

Leaves fallen from riparian zones and carried by the river (especially during floods) to the fluvial-estuarine
areas can represent an important source of nutrients to the aquatic food webs. However, little is known about
the dynamics of this leaf material at the end of the river continuum. Here we assessed the decomposition of
alder (Alnus glutinosa L.) and poplar (Populus nigra L.) in the fluvial-estuarine environment of the Mondego
river. Leaves were exposed in fine (0.5 mm; FM) and coarse (1 mm; CM) mesh bags at 3 experimental sites:
one located upstream (low salinity levels) and the other two located in the north and south arms of the estuary
(both polyhaline areas, but with distinct habitat structure). Leaf decomposition was faster with poplar than alder
leaves. Decomposition rates correlated with higher contents of phosphorus and lower phenolic contents found
on poplar. As no differences in decomposition rates were found between mesh bags, a dominant microbialmediated decomposition is suggested. However, the potential involvement of meiofauna in the decomposition
process cannot be ruled out, particularly at sites with a mud substratum. Salinity affected the decomposition of
both leaf species. The relative importance of leaves to the fluvial-estuarine energetic budget merits further
attention.

Microplastics (MP) which have been defined as plastic debris under 5 mm size are widespread and ubiquitous
contaminants in the marine environment. They can be up taken by marine organisms causing physical effects
which can lead to dead. They can also cause chemical toxicity induced by chemicals incorporated during their
manufacture and/or by environmental contaminants incorporated during their permanence into the
environment. A high concern exists regarding the entrance of these chemicals into food webs through MP
ingestion or absorption increasing the risks of exposure to top predators and humans. The presence of MP
may modify the biotransformation and toxicity of other environmental contaminants and more knowledge on
this topic is needed to improve marine risk assessments. Therefore, the objective of the present study was to
investigate the influence of MP on the acute toxicity of chromium, a common environmental contaminant in
estuaries, in early 0+ juveniles of the common goby (Pomatoschistus microps). Acute 96h bioassays, based on
mortality, predatory performance and several biomarkers were carried out with juveniles of the Minho and Lima
River estuaries (NW Iberian coast) using MP and chromium as test substances (alone and in mixture). The
results are discussed in relation to the influence of MP on the biotransformation and toxicity of chromium and
on the developmental exposure of fish to background environmental contamination in their original habitats.

involved in functions crucial for the survival and performance of the fish and indicative of exposure/effects of
environmental contaminants were determined. Simultaneously, sixteen abiotic parameters were
measured/determined in water and sediments. The results are discussed in relation to adverse effects caused

longicornis consists of twelve equations for twelve states of variables, six for the mass Wi and six for the

stages were grouped as follows: eggs – Egg, stages not taking food – NI-NII, subsequent nauplii stages – NIIINVI, two copepodid stages – CI-CIII and CIV-CV and adult organisms – CVI. Seasonal dynamics of T.
longicornis is described by average changes in the total biomass as a sum of biomass of the examined
ontogenesis stages, which are the sum of the products of the mass Wi and the abundance Zi of individual

was called 3D-CEMBS. The ocean model (POP, version 2.1) and the ice model (CICE, version 4.0) work in the
active mode, and they are imposed by atmospheric data model (datm7). 3D-CEMBS model is also equipped
with the ecosystem module. In addition, river inflow of freshwater and nutrient deposition is processed by land
model. The main task of the datm7 is to interpolate atmospheric data on model domain. External forces are
daily-averaged for the period of forty years, which come from ECMWF re-analysis (ERA-40). At present, in the
operational mode, 48-hour atmospheric forecasts are used, which are supplied by the UM model of the
Interdisciplinary Centre for Mathematical and Computational Modelling of the Warsaw University.

Major purpose of this study is to characterize population dynamics of three major Baltic calanoid copepod
species (Acartia spp., Temora longicornis and Pseudocalanus sp.) in the Gulf of Gdansk in years 2006 - 2007.
This paper focus mostly on biomass estimation, production and mortality rates. All three species had the
-3
highest observed biomass in summer 2007 and it was 12.62, 9.16 and 0.80 mg C m for Acartia spp., T.
longicornis and Pseudocalanus sp. respectively. While highest daily production rates for those species were
-2
28.22, 18.47, 1.34 mg C m , all recorded in summer 2007. Mortality rates were calculated for all copepodit
stages of selected species, and in most cases highest values were observed during summer seasons.

Blackfordia virginica is a cnidarian native to southeastern Europe or the Atlantic coast of North America. It was
introduced in two Portuguese estuaries, the Mira and the Guadiana estuaries. The spatial distribution of the
medusae population was determined in the Mira estuary, southwest of Portugal. Quarterly sampling surveys
conducted between September 2012 and June 2013 showed that the higher density of the medusa stage was
3
recorded during summer in the upstream area of the estuary (982 medusae/m ), associated with a higher
abundance of oyster shells and higher percentage of hard substrate. Smaller jellyfish were sampled in the
vicinity of these hard substrate locations, suggesting they are preferential habitats for polyp’s settlement.

Echinogammarus marinus (Leach, 1815) is a gammarid amphipod that occurs in high densities on hard
substrates, especially when associated with Fucus spp. (Marques and Nogueira, 1991). Intersexuality, a
condition where an individual possesses both male and female phenotypes, has been widely reported in
crustaceans and E. marinus is no exception (Ford et al, 2003). The causes for this abnormality are still
unknown but parasitism by microsporidia enhanced by pollution seems the most plausible (Ford et al, 2006).
Our goal was to evaluate the occurrence of intersex in E. marinus populations from three Portuguese estuaries
with different environmental pressures: Minho (low-impacted), Mondego (medium-impacted) and Ave (highlyimpacted). If no intersex was present we tried to determine if the individuals were infected by microsporidia
parasites. Our results showed an 8.3% infection in the Minho estuary, 2.7% in the Mondego estuary and 20%
in the Ave populations, all infected with the microsporidia genus Dictyocoela. The results from Ave suggest a
strong connection between environmental impacts and infection by microsporidia parasites, however the
percentage of infected individuals from Minho and Mondego estuaries demonstrate that either there is another
factor inducing parasitism or the Minho estuary might not be as low-impacted as we thought.

In nursery areas optimal habitat characteristics, such as high prey availability and low predation, promote
enhanced fish growth and condition. Small scale variability of environmental parameters throughout an
estuarine nursery may be responsible for differential spatial and temporal patterns in fish density and condition.
The northern coast of Portugal represents the southern distribution limit of the flounder Platichthys flesus.
Environmental changes may increase the vulnerability of juvenile flounder in this area, resulting in poorer
condition affecting fish recruitment. These aspects were investigated in the Lima estuary (northern Portugal)
using spatial and temporal patterns of YOY, flounder condition, and its relationship with habitat features.
Flounder juveniles and their main prey (macroinvertebrates) as well as environmental data were collected
monthly between May and October, in 2010 and 2013. Generalized linear models (GLM) relating flounder
condition (Fulton’s K) to habitat characteristics showed that sediment and water characteristics together with
prey availability shaped spatial patterns of YOY flounder condition, with potential effects on growth, survival
and recruitment to adult populations. The improved knowledge of habitat features promoting YOY flounder
condition in its distribution limit will help prioritize areas for conservation and efficient management.

We studied the influence of mysids species number on their feeding rates to test how the structure of mysids
assemblage may affect carbon fluxes in the Cananeia estuary. Three types of experiments were conducted to:
(i) evaluate mysids feeding rates and selectivity on the natural zooplankton assemblage; (ii) determinate their
functional responses to varying food density; and (iii) check inter- and intraspecific predation between mysids.
For the former two experiments, three mysids species were incubated isolated or combined (2 species:
Metamysidopsis elongata atlantica + Mysidopsis coelhoi; 3 species: M. e. atlantica + M. coelhoi +
Chlamydopleon dissimile), totalizing 5 treatments. The three mysid species had opportunistic feeding behavior
on the natural zooplankton assemblage, but there was evidence of avoidance of medium-size prey (300-400
µm) mostly comprised of Oithona spp., probably due to a combination of small size and prey swimming
patterns. Ingestion rates showed a non-linear increase with increasing food concentrations, suggesting a type
II functional response for all mysids species and combination of species. There were both positive
(complementarity effect) and negative effects of species combination on the investigated response. Negative
interactions were probably linked to intraguild predation, which resulted in a reduction of mysids predation over
the zooplankton.

Environmental cues are major factors regulating reproductive timing, especially in organisms with external
fertilization, and are crucial for the success, distribution and abundance of marine organisms. Furthermore,
they might explain the divergence of reproductive modes in sympatric closely related species. We studied
reproductive investment between populations from exposed rocky shore and neighbouring sheltered estuarine
habitats. As a model we used sister species that are sympatric through much of their respective ranges;
hermaphroditic Fucus guiryi and dioecious Fucus vesiculosus. Over two months, daily gamete release (and
relative synchrony) was recorded, together with recruitment and population structure. Our results show a clear
semilunar pattern of gamete release, coincident with neap tides in both species and habitats, but release
events in hermaphrodites occupied broader temporal windows (=reduced synchrony) in estuarine than opencoast habitats. Settlement and recruitment in both species were significantly lower in the estuary than on the
open-coast. However, the estuarine settlement to recruitment ratio (=recruitment success) was higher, as was
the density of mature individuals, and the number of receptacles. This work provides important insights into
reproductive investment in different habitats of two sympatric sister species.

Microplastics (MP) are widespread environmental contaminants in the marine environment with estuaries and
coastal areas of industrialized regions being considered hotspots. In the environment, MP are able to
incorporate other contaminants such as nickel which is commonly found in estuaries raising concern on the
potential toxicological interactions that may occur after uptake of MP by marine organisms. Thus, here, such
interactions were investigated in early juveniles of the common goby (Pomatoschistus microps) from two wild
populations of the NW Iberian coast exposed to different levels of background environmental contamination.
Juveniles were collected in the field and 96h laboratory bioassays based on mortality, predatory behaviour and
biomarkers were carried out in the presence and absence of MP. In the range of concentrations tested, nickel
alone induced mortality, adverse effects on the predatory behaviour and on several biomarkers. In the
presence of MP, several of these alterations were modified indicating toxicological interactions between MP
110
and nickel. Because P. microps is a crucial intermediate predator in several European ecosystems, the
findings of the present study raise concern on the potential increased risk to higher predators and highlight the
importance of further investigating MP and other environmental contaminants in marine organisms.

Cordylophora caspia is a Ponto-Caspian invasive colonial hydroid, spread around the world and causing
serious fouling problems. We studied the occurrence of this species in water bodies of the Polish costal area:
Szczecin and Vistula Lagoons, the Bay of Puck, and 13 costal lakes. Samples were taken in 2005-2010 form
the stalks of Phragmites australis Trin ex Steude. The highest densities of C. caspia were observed in the

western part of the study area, in the Szczecin Lagoon (average 5100 zooids m ) and Lake Resko

Przymorskie (average 4800 zooids m ), while the species was not observed in the reeds in the Vistula

Lagoon. In the whole area, water salinity ranged from 0.14 to 4.29 g.L ; the highest densities of C. caspia,

exceeding 4700 zooids m , were observed in salinities of 1.176 to 1.800 g.L . C. caspia increasingly colonizes
freshwater ecosystems, but in Poland its occurrence remains limited to the Baltic coastal zone. Our study
shows an initial stage of invasion which can be expected to proceed from the brackish waters of lagoons and
coastal lakes to inland freshwater ecosystems.

The frequency of extreme events has been increasing in several regions as consequence of global climate
changes, as well as pollution as result of human population increase. These pressures may have a deep
impact on the diversity and functioning of molluscs’ communities, often acting in benefice of bivalve invasive
species when in competition with native species, potentially reducing ecosystem services. Thus, here, the
health status of the Asian clam (Corbicula fluminea) populations inhabiting the tidal freshwater areas of Minho
and Lima Rivers estuaries was investigated seasonally for one year in relation to abiotic variation (e.g.
temperature, nutrients, etc) and environmental contamination. The multi-parameter approach used highlighted
important time and spatial variation patterns and identified environmental pressures significantly decreasing C.
fluminea health status. These findings increased the knowledge on the factors leading to massive mortality
events in bivalves, validated an important tool for long-term monitoring and environmental risk assessment of
climate changes, pollution, and invasive species in estuarine tidal freshwater areas.

Mercury is a common contaminant in estuaries. It may be accumulated by benthic species, especially bivalves,
thus increasing the risks of exposure and effects on their predators and human consumers. Corbicula fluminea
is an invasive species that has been causing severe ecological and economic impacts in several regions,
including Europe and North America. The aim of this study was to relate the early effects of mercury, through
the assessment of biomarkers (oxidative stress, biotransformation, neurotoxicity and energy production) with
the impact on oxygen consumption rate on Corbicula fluminea from populations of Minho and Lima estuaries.
111
Clams were individually exposed to different treatments aimed at to assess the effects of mercury and the
potential post-exposure recovery of organisms. Results show that mercury induced a reduction of oxygen
consumption rate and adverse effects on important physiological functions in organisms from both populations.
In certain endpoints, some degree of recovery was observed. This study highlights the importance of using a
multi-marker approach when assessing the effects of mercury. The implications for environmental
management and risk assessment are discussed.

Sediment metal speciation is known to be affected by a variety of factors, inherent to the elevational gradient
along the marsh and consequent differential inundation. This is one of the major factors influencing halophytic
species distribution due to their differential tolerance to salinity and submersion. It is also known that different
species have different influences on the sediment’s metal speciation, with consequent implications on their
metal accumulation abilities. It is known that Halimione portulacoides is a typical phytoremediator species,
extracting large amounts of heavy metals from its rhizosediments where they appear in rather available forms.
Spartina maritima, in turn, is the typical phytostabilizer species, changing the metal partition in the
rhizosediments into less available forms, thus with lower accumulation of these elements in its tissues. In the
present work the authors intend to evaluate how these differences in sediment metal speciation, inherent to the
physicochemical environment but also to a specific halophytic habitat, influence the metal uptake into the plant
cover, and more specifically how it will be allocated at the cellular level, considering the different tolerance and
avoiding strategies exhibited by three different halophyte plants species.

Mediterranean coastal dunes have been highly modified by human impacts, so understanding their
conservation status is crucial to preserve these extremely vulnerable habitats. The aims of this work were to
assess the conservation status of coastal dunes through the use of plant diversity indices and to analyze the
effects of human disturbance on these environments. The study was carried out on the well-preserved dune
system of Is Arenas (CW Sardinia), one of the widest and most important in the Mediterranean basin. In order
to analyze the full spectrum of plant-communities, six transects and 54 plots were sampled. The overall plant
diversity was measured with NHDune diversity index and the incidence of invasive species was calculated
using the naturalness index (N). Analysis of the overall dunes plant diversity confirmed the usefulness of the
NHDune to quantify species richness and the low usefulness of N to assess human impact, because N mainly
depends on the occurrence and abundance of alien species, which were quite low in our study area. Therefore
the NHDune represents a useful tool to assess the conservation status of a coastal dune systems in the
Mediterranean coasts and to guide the proposal and implementation of conservation measures.

Small-scale artisanal fisheries of clam species are an important economic activity in the Tagus estuary,
Portugal. The pullet carpet shell (Venerupis corrugata) the grooved carpet shell (Ruditapes decussatus) and
the common cockle (Cerastoderma spp.) were the most important clam fisheries in this estuary over the past
decades. Nevertheless, the standing stocks of those bivalves saw a sharp decline during the past 5 years,
coinciding with the recent introduction and rapid population growth of the Manila clam (Ruditapes
philippinarum). To evaluate the current status of the populations of V. corrugata and R. philippinarum the
112
spatial distribution and abundances of both species in the Tagus estuary were identified. Fishing communities’
responses to changes in the bivalves communities were also assessed via sociological surveys which
indicated that pullet carpet shell fisheries were suspended once they became economically unsustainable.
Most commercial fishermen relocated their fishing activities to catch the economically more lucrative Manila
clam. This species is also exploited by large numbers of illegal fishermen. Both recently observed shifts in
fishing practice imply an urgent need to revise the regulation associated with clam fisheries in the Tagus
estuary.

Estuaries are essential fish habitats, comprising several ecological functions and a high diversity in life-history
stages. Globally, estuarine fish assemblages have common features but these are more apparent in the adult
stages at a functional guild level rather than a taxonomic level. The paper considers this feature with the
ichthyoplankton across geographical and latitudinal regions by comparing northern temperate, southern
temperate and tropical estuaries. The Lima Estuary (Portugal) is small with a vertically stratified channel, the
Wilson Inlet (Western Australia) is a small, microtidal temporarily closed and occasionally hypersaline estuary,
the Swan Estuary is a larger, open Western Australian estuary, and the Macaé (Brazil) is a bar-built estuary,
with a narrow and shallow main channel. Spatial (estuarine gradient) and seasonal sampling showed that, as
expected given the different biogeographic realms, there were no species in common but there were
similarities according to the functional guilds represented by the ichthyoplankton despite the influence of
different hydromorphological conditions. The assemblages supported marine, estuarine, migratory and
freshwater elements. The present study reinforces the use of the functional approach to make valid
comparisons across geographically different assemblages; it highlights the worldwide applicability of ecological
guilds in fish ecology, even in early development stages.

Macrofauna, occupies a key position in the center of this trophic structure, feeding on primary food sources
and being the confluence between marine and terrestrial food webs, in which, birds and fish are their main top
predators. We investigate the trophic functioning in a pristine sandy beach, located inside a protected area

Marine ecosystems are complex adaptive systems (CAS) in which macroscopic dynamics emerge from
numerous nonlinear interactions over multiple spatial and temporal scales in a hierarchical structure. Capturing
the inherent complexity of marine systems remains a major challenge in ecosystem-based management plans.
Often, the observed state of these dynamic systems under pressure will initially show little obvious change until
a critical threshold is reached at which point a sudden shift to a contrasting dynamical regime takes place. One
possible way to represent coastal and marine (complex adaptive) systems in a complex theory framework is to
evaluate ecological resilience sensu Holling (1973), i.e. the magnitude of disturbance that can be tolerated
before a system moves into a different region of state space and a different set of controls (interactions,
feedbacks,..). Ecological resilience implies that ecological systems do not simply track environmental forcing
but are capable of self-organization.

Pertuis Charentais are located in the middle of the French Atlantic coast. This semi-sheltered 600 km² area is
bounded by two islands (Oléron and Ré) to the west, and harbours the main French oyster industry centre in
Marennes-Oléron Bay. As known elsewhere in Europe, the slipper limpet Crepidula fornicata (L.) has colonized
subtidal and low intertidal muddy grounds of Pertuis Charentais since the mid 1970’s. A review of available
information aims at describing changes in C. fornicata occurrence over the period 1974 to 2011, competition
with cultivated and/or exploited species, and effects on diversity on benthic macrofauna and marine habitats.
First occurrence of C. fornicata in Pertuis Charentais was dated May 1974. Since then, the latest 2011 stock
assessment performed with acoustic mapping, grab-samples and GIS tools reveals a 70000 ± 20000 tonnes
stock spread over 45 km². Co-occurrence of C. fornicata and cultivated oysters in close vicinity suggests
spatial competition and potential trophic competition. At low scale of diversity, C. fornicata may stimulate
benthic macrofauna, particularly epifauna such as Chlamys varia. However, spread of C. fornicata grounds
impacted sandy mud habitats colonised by Pecten maximus and may impact maerl beds, as recently
discovered in 2011 North to Ré Island.

Predicting future range dynamics under climate change: the case of a structuring coral in its global
range
Silva I, Boavida J, Assis J, Serrão EA
Understanding variations in distribution and persistence of species across global ranges over time remains a
critical research question in conservation ecology. We aim to identify the environmental variables shaping the
global distribution of the red gorgonian, Paramuricea clavata, and to predict its potential habitat in present and
future times, using niche modeling. This ecosystem engineer has a limited distribution in the Mediterranean
Sea and adjacent Atlantic Ocean and has been severely affected by mass mortality events during past periods
of increased seawater temperatures. The relatively poor knowledge on the ecology and distribution of this
structuring species represents a significant challenge for modeling and prediction of its fundamental niche. The
results showed that the distribution of the red gorgonian is shaped by the extreme temperatures during
reproductive periods and by the availability of inorganic nutrients when adults are non-reproductive. A broader
potential habitat than that of known occurrences was uncovered. Furthermore, future range shifts were
discussed using different proxies of climate change. This study contributes to a better understanding of spatial
and temporal variations in the populations of a key marine species, with implications for conservation
strategies.

Seagrass meadows carry out significant ecological processes through the promotion of biodiversity and
contributing to the maintenance of physical, chemical and biological conditions in the overall system. Even
though the important ecosystem services provided, seagrass meadows have been declining worldwide due to
many direct and indirect human-derived pressures. According to this global trend, seagrass meadows in Ria de
Aveiro (PT) coastal lagoon have been declining since the 1960’s, mainly due to harbour activities (e.g. fishing
and commercial), and its inherent pressures. Subtidal seagrasses have totally disappeared and the intertidal
meadows extension greatly decreased along Ria, consistent with the last records. This work evaluates the
spatial and temporal variation of Zostera noltii intertidal meadows at Mira channel (Ria de Aveiro), comparing
its extent at the beginning of the XXI century with its current distribution. Therefore, it is assessed if either the
meadows extent followed the declining trend or its degradation and decline slowed down.

Navakavu is a fishing community close to Fiji’s capital, Suva. A marine protected area was established in 2001
to manage their traditional fishing grounds. This study combines taxonomic and ecological expertise with
indigenous community knowledge as a basis for assessing biodiversity and ecosystem health to improve longterm management. Methodology consists of ethnobiological interviews; monitoring and field surveys; and
identification and documentation of specimens. Preliminary analyses indicate that a large number of taxa have
returned to the area for the first time after 20-40 years or are in higher numbers and larger age-classes than
before the establishment of protected area. It also shows that the fishery was degraded due to overfishing and
sedimentation resulting in reduced biodiversity. The survey has validated short-term conventional surveys
showing increasing abundance of finfish and invertebrates, as well as identifying other important taxa returning
after many years, many being seen for the first time ever by the older generation. Such in-depth retrospective
taxonomic studies can provide important ethnobiological data including species composition and abundance;
the state of the environment before degradation; the impact of degradation on taxa; and the return of species.
The survey has also recorded seriously threatened local taxonomic and ecological knowledge.

The Pacific oyster Crassostrea gigas was introduced in Europe in the early 1970s, for shellfish culture purpose.
It became progressively an invasive species all along the European Atlantic coasts up to Norway. Relatively
warm summers are supposed to be one of the major cause of this invasion. In such context, the aim of the
present study was to investigate the variability of the main life traits of C. gigas and especially its reproductive
dynamics in relation to environmental forcing variables. To this end, a bioenergetic growth model, based on the
dynamic energy budget (DEB) theory, was applied over a long period (1998 to 2013) in a mid-latitudinal point
in Europe: Bourgneuf Bay in France. Forcing variables were extracted from satellite measurements and from
coastal monitoring network. A validation step over the 16 years showed the fairly good agreement between
simulation and observation, proving the efficiency of the model for capturing life traits of C. gigas. Moreover,
the model application highlights the relation between environmental conditions in late spring and reproductive
traits. And finally, a historical retrospective exercise from 1960 to 2013 shows the potential effects of global
warming on spawning date and sustains the species propagation explanation.

Mesoscale variability of the microplankton (53-200 µm) and the mesoplankton (0.2-2 mm) in relation to
oceanographic factors and phytoplankton biomass were compared off the Catalan coast (NW Mediterranean)
during the summer stratification (June) and autumn mixing (November) periods in 2005. Plankton mesoscale
variability in relation to environmental variables showed higher complexity in June, where environmental
horizontal and vertical gradients were more marked than in November. The development of the subsurface
phytoplankton maxima, the influence of the Ebro plume and particular flow structures identified as an eddy in
the wide shelf zone to the north of the Ebro Delta governed the mesoscale spatial structure of plankton
communities in June, and the main modes of variability differed between the micropankton and the
mesoplankton. In November, however, micropankton and mesoplankton showed similar predominant patterns
of spatial variability, and illustrated the typical inshore-offshore gradient in zooplankton abundance and
biomass in the western Mediterranean, with coastal areas being significantly richer than oceanic areas, and
associated to compositional gradients related to differences in pelagic food web structure between mesotrophic
coastal waters and oligotrophic oceanic waters. These biological gradients were clearly shaped in our case by
the Catalan Current and by the intrusion of open sea waters across the shelf off the Ebro Delta.

In this work we analysed the changes in abundance and composition of two plankton fractions (micro- and
mesoplankton) off the Catalan coast (NW Mediterranean) from summer stratification conditions (June) to fall
mixing conditions (November) in 2005. No noticeable differences for the ratio of biomass between
microplankton and mesoplankton were obtained from June to November, denoting that the decrease of
biomass was of similar order of magnitude in both fractions. In contrast, the ratio of abundance increased
around fivefold in average from June to November as a result of the increase of microplankton abundance and
the decrease of mesoplankton abundance, evidencing that the contribution of small forms to the total number
was much higher in November. The microplankton abundance increased from June to November mainly due to
the increase of dinoflagellates, tintinnids and radiolarians, in such a way that copepods were replaced by those
groups in the dominance of the assemblage. Mesoplankton, however, decreased due mainly to the decrease
of large armoured dinoflagellates, cladocerans, doliolids and appendicularians, since copepod abundance and
contribution of larger species increased. These changes accounted for differences in the dominant trophic
pathways to fish larvae between periods.

In North Atlantic estuaries, the copepod community is in general dominated by Acartia species in a
considerable period of time. These organisms are crucial preys for several planktivorous fish that depend of
them for their development. The main purpose of this study was to estimate and compare the distribution,
116
production and production/biomass ratio values of Acartia clausi and Acartia tonsa, in the estuaries of Minho
and Lima Rivers (NW Iberian Peninsula), using image analysis techniques. These estuaries were selected
because they have different levels and types of predominant contaminants and have been increasingly
affected by anthropogenic pressures and alterations due to global climate changes. Sampling was carried out
from 2010 to 2011. Significant spatial and temporal differences were observed in both Acartia spp. distribution
and production/biomass ratio. Overall results indicated that both species play an important role in transferring
energy to higher trophic levels in both studied estuarine systems.

Biologic indicators have been used successfully to assess water quality worldwide, providing valuable
information for water resource management. Recent evidences have highlighted the potential of pelagic
zooplankton community composition and variation as bioindicator of water-masses influence and water quality.
In this study, zooplankton data from two European Atlantic coast estuaries (Minho and Lima Rivers estuaries,
Iberian Peninsula) were analyzed to study the influence of water quality and Atlantic water-masses on the
spatial and temporal variation of the zooplankton community. The study intends to take advantage of the
comparison of both Biotic Integrity and species diversity indexes, based on spatial and seasonal pelagic
zooplanktonic community structure, in relation to multi-stressor exposure. Overall results show that, at these
areas, zooplankton composition and seasonal dynamics are likely to be good indicators of water-mass
influence and changes. Additionally, obtained data suggest that micro and mesozooplanktonic organisms can
be considered bioindicators of water quality in several areas subjected to abiotic and anthropogenic
disturbance.

Invasive species can affect the function and structure of natural ecological communities, hence it is critical to
understand and predict their potential for spreading. The spread of invasive species is mainly controlled by
their way of dispersal and/or habitat availability. In this study we aimed to determine which of these factors
might be limiting the spread of Mytilus galloprovincialis along South African shores. This mussel species,
native to the Mediterranean, invaded South Africa in the late 1970’s. After its first detection, it expanded at very
fast rates and became the most successful marine invader in South Africa. However, in the last decade the
spread has ceased. Niche models were built using records from both the native and invaded ranges against
marine and terrestrial environmental variables associated to the different reproductive life stages of M.
galloprovincialis. Results showed that the distribution of this species is dictated by extremes in air and sea
surface temperature throughout both reproductive and non-reproductive stages. Distribution models in
comparison with field records gathered throughout the invasive range demonstrated that in the past four
decades this species has already occupied the entire available niche in South Africa and that its expansion is
currently limited by habitat availability. Future invasive range shifts were assessed and discussed by
transferring models to different proxies of climate change.

Few studies have focused on the effects of climatic changes on the estuaries of the Amazon coastal region.
The Caeté estuary is affected by untreated sewage discharged into the upper estuary, as well as by the
cyclical occurrence of anomalous rainfall patterns. In this context, the present study evaluated the short-term
fluctuations on the water quality of this estuary, during spring (March, 2012) and neap tides (April, 2012)
marked by an El Niño event. The data recorded during this period revealed relatively high concentrations of
nitrate (up to 8.0 µm) and phosphate (up to 0.9 µm), probably due to the abnormally low freshwater discharge
(related in turn to the reduced rainfall). During the spring tides, phosphate and nitrate levels were significantly
higher during the flood tide, whereas during the neap tides, only phosphate concentrations varied significantly,
but with higher values being recorded on the ebb tide. Fecal coliform values of 1100 MPN/100 ml were
recorded at all stations. Our results indicated that, during an El Niño event, the reduced freshwater discharge
can have caused a decrease in the dilution of the sewage released into the upper Caeté estuary, which
resulted in an increase in phosphate, nitrate, and fecal coliform concentrations.

The aim of this study is to characterize the influence of natural (mangrove area) vs anthropogenic (sewage
effluents) factors on the water quality of the Caeté estuary. Hydrodynamic, hydrological and microbiological
data were taken during one climatic year (09/2010-10/2011) at 8 stations along the estuary (from lower to
upper estuary). During the dry season, when the total rainfall was of 500 mm and riverine discharge smaller
3
than 1200 m .s., the estuarine water was more saline, alkaline and richer in nutrients (maximum of 1.1 µm
Phosphate-PO4, 31.5 µm Nitrate-NO2 and 6.9 µm Nitrite-NO3) and, frequently presented concentrations of
thermotolerant coliforms up to 1100 NMP/100ml. In the rainy season (2500 mm of rainfall and river flow up to
3 -1
1500 m .s ), salinity, pH, dissolved nutrients (max of 0.6 µm Phosphate-PO4, 12.0 µm Nitrate-NO2 and 3.0 µm
Nitrite-NO3) and thermotolerants coliforms (lower frequency of <1100 NMP/100ml) reached lower values. High
-3
chlorophyll-a concentration (max 45.2 mg.m ) occurred in both monitored seasons, indicating a high primary
productivity. Sewage effluents are responsible of the high levels of coliforms. Obtained results permit to assess
the role of rainfall pattern in controlling monthly oscillations in hydrological and microbiological variables and, to
identify the role of anthropogenic and natural forcings in such conditions.

Estuaries are highly productive and dynamic ecosystems, frequently subjected to considerable impacts derived
from human activities. Organic and inorganic chemical pollutants originating upstream are transported in the
freshwater and suspended sediment particles, adding up to the contaminant load derived of human activities in
the estuarine vicinity. Hence, estuaries play a major role in filtering the amount of contaminants that reach the
ocean, by accumulation in the sediments or in biota, or by transformation due to organisms’ metabolic
mechanisms. Yet, the fate, toxicity and bioavailability of chemical pollutants are highly dependent on various
physical, chemical and biological characteristics of these ecosystems. The general course of contaminants
throughout various estuarine components (e.g. sediments, habitat type, trophic structure, species richness)
was analyzed in order to develop a framework that enabled comparison between systems with different
degrees of complexity. Increased complexity was described as highest number of system components and
multiplicity of associations between them. Overall, in this first approach, more complex systems evidenced
higher purification or filtering ability if key components were present.

Although it is known that salt marsh plants can take up metals in a process known as phytoremediation, there
is a lack of information about metallic NPs interaction with these plants. On the other hand, microbial
communities display important roles in the salt marsh ecosystems, and plants can benefit from the microbial
activity during phytoremediation processes. Nevertheless, depending on its levels and forms, metals can be
toxic to microorganisms, fact that can eventually compromise their ecological functions. In this vein, the aim of
present study was to investigate, in the laboratory, the effect of Cu metallic NPs (as CuO) on the microbial
communities associated to the roots of a salt marsh plant (Halimione portulacoides), and its implications for
phytoremediation. Experiments were conducted with sediment elutriate, a simplified natural medium, being the
plant exposed for 1 week to medium contaminated either with CuO or with Cu (II). Microbial community was
characterised in terms of abundance (estimated by DAPI) and genetic structure (evaluated by ARISA), and
metal uptake was evaluated in plant tissues (by atomic absorption spectroscopy). Results revealed significant
(p<0.05) differences in terms of metal uptake between plants exposed to Cu in the two different forms. The
characterization of the microbial community will allow a deeper interpretation of these results.

Anthropogenic impact on estuarine ecosystems is affecting a number of critical benefits, compromising the
maintenance of ecosystem services. The purpose of this study is to provide an overview of the main
ecosystem services of Douro estuary (NW Portugal) by estimating the key economic values arising from the
services provided by this system. In addition, we discuss how the natural variability and anthropogenic
pressures affect the ecological functions and ecosystem services, influencing their economic value. This study
represents the first survey on ecosystem services for Douro estuary. The collected data will be interpreted in
the light of the existing information on natural and anthropogenic driven changes. The compilation of data,
including information from several years, on anthropogenic impacts includes not only the introduction of
pollutants (including nutrients load, PAHs, metals, PCBs, PBDEs, pharmaceuticals, endocrine disruptors) into
different ecosystem compartments (water, sediments, biota), but also the impact of habitat loss and change.
This study points to the importance of further multidisciplinary collaborative research, integrating ecological,
economic and social sciences, regarding future management and regulation of anthropogenic activities in
estuarine ecosystems.

The main ecological patterns and the understanding of the functioning of estuarine ecosystems are difficult to
evaluate due to natural and human induced complexity and variability. In this context, a holistic and broad
geographical approach appears particularly useful. This study analysed, at a worldwide scale, the main
patterns of fish diversity in estuaries, assessing the relationships between species richness and latitude,
continental shelf width, estuary area, estuary mouth width. Seventy one estuarine systems were considered
being data obtained from literature and geographical information system. Exploratory analyses, correlation
tests and generalized linear model (GLM) were performed to reveal major trends. GLM highlighted the
dominant effect of the estuary area followed by the latitude and the mouth width on fish species richness.
Species richness increased towards the equator, and it was positively correlated with estuary area and estuary
mouth width. Estuary area probably reflects a higher diversity of habitats and/or productivity, which are key
features of the estuarine ecosystem functioning. The mouth width effect is strongly related to the connectivity
ensured by marine and diadromous fish species. Finally, the latitudinal pattern in fish species richness
suggested an impact of climate and global hydrographic processes on fish communities in estuaries.

Ecosystems may transition from one stable state to another when perturbed. We found a considerable amount
of variation in the abundance and composition of the aquatic macroinvertebrate community and the trophic
niche of Palaemon varians in Veta La Palma wetland. This variation, consistent with the concept of alternative
stable state, was mainly determined by a different rate of water exchange with the estuarine waters. A
transitory state in these experimental ponds occurred when the flow regime between the adjacent Guadalquivir
and these experimental ponds exceeded a threshold. The low flow regime in ponds resulted in stable state
(Extensive ponds) meanwhile a higher flow of exchange water resulted in a transitory state (Mixed ponds)
between the wetland and the estuary. The transitory state of these mixed ponds had a higher abundance of
estuarine fauna such as mysids, an incursion of the exotic species Palaemon macrodactylus and a different
carbon isotopic signature in the aquatic community. This experimental study is a valuable tool for an integrated
management between river basin and wetlands because it allows quantifying the state shift by flow regime and
values the importance of estuarine marsh connexion.

Salt marshes are well-known sinks of carbon and nitrogen, incorporating them both into sediment and in the
halophyte biomass, being key players in the estuarine biogeochemical cycles. Due to aboveground
senescence there will inevitably occur losses of nutrient and metall rich detritus, becoming prone to the tidal
flooding and hydrodynamic regime. On the other hand, the ongoing climate change effects, such as Sea Level
Rise (SLR) are known to have influence in the estuarine circulation. The Tagus estuary is a mesotidal system
located in the western Portuguese coast, presenting an embayment geometry and characterized by large
areas of salt marshes and tidal flats distributed along its sides. Residual circulation, tidal asymmetry, tidal
dissipation and detritus Lagrangian tragectories were determined from numerical modelling results of the
MOHID 2D model that was applied to this coastal system, considering the actual sea level and a sea level rise
(SLR) scenario. This way, model results of Lagrangian particles indicate that the detrital particles are highly
dispersed, with large amounts approaching the outer area of the estuary a feature that is highly enhanced in
the SLR scenario. These features may have two major implications: 1) enhance the fuelling of secondary
production in the coastal shelf and 2) metal exports and possible contamination of the coastal area. These two
consequences (positive and negative) acquire even more importance if all the marsh extension along all the
estuary is considered along with its elevated amount of plant-generated detritus and the possible
consequences on the ocean water quality MSFD-sensu.

In southern European coastal waters brown macroalgae of the genus Cystoseira are important foundation
species that provide essential ecosystem services in the form of algal forests. Species of the genus are
disappearing at an alarming rate. Out of concern, six species are included in the Bern convention and the
genus in general is also used as a water quality indicator in the European Water Framework Directive. In order
to understand future trends in distribution and diversity of intertidal Cystoseira species in Portugal and the
genetic impacts of current events we performed temperature experiments with the four most important
Cystoseira species in Portugal, and monitored current seawater temperature in the intertidal pools they inhabit.
We also described the genetic diversity of one of these species along the Portuguese coast using
microsatellites. Experiments showed marked differences in temperature tolerance among Cystoseira species
and indicate that the maximum temperature currently encountered in the field in their habitats (32 ºC)
represents a threshold beyond which species are affected. This leads us to conclude that Cystoseira canopies
in the Portuguese intertidal are close to their temperature tolerance, and their distributions are likely to shift
northwards, potentially changing species and genetic diversity as ranges shift.

Climate-induced changes among decapods have played a significant role in the North Sea, resulting in a
propagation of the climatic signal through the food web. At the ecosystem level, this trophic amplification has
rapidly led the North Sea into a new dynamic regime. This ecosystem reorganization has extended beyond
marine realm and has influenced neighboring terrestrial systems through gulls. Sea temperature is one of the
fundamental abiotic factors affecting both the development and the survival of decapod larvae. Temperature
influences all physiological and ecological processes of aquatic invertebrates and their life stages. Increases in
temperature lead to reduce the duration in the development of organisms up to a certain optimum in a
nonlinear way. Because the duration of the larval period is known to influence both larval dispersal distance
and survival, we investigate here whether this biological mechanism could have a direct influence on the new
ecosystem dynamic regime that took place in the North Sea.

The effect of crude oil on the bivalve mollusks (mussel, Mytilus edulis, and northern horsemussel, Modiolus
modiolus) from the White Sea was studied. The parameters of detoxification capacity (GSH level, GST and
EROD activity) and protein quality control (intracellular protease activity in cytosol and lysosome fractions) as
well as lysosome membrane stability were measured in mussel organs such as mantle, hepatopancreas, and
gills. Oil spill was simulated through the adhesion of crude oil on shore gravel (concn. 1, 5, or 50 ml per 5 kg of
gravel) with subsequent dissolution of unbound oil fraction in 20L of sea water. After 10-days of laboratory preexposition subtidal mussels were exposed to different oil concentrations for 1 to 10 days. Besides the doseand time-responses the effect of desalination on oil toxicity to mollusks was examined. Field observations of oil
contamination effects were made on invertebrates sampled from the several coastal areas in the Kandalaksha
Gulf of the White Sea highly polluted by oil due to repeated oil spills (Belomorsk Neftebaza). Mollusk
biochemical and physiological responses to oil uptake and the dynamics in responses are discussed. The work

Marine organisms, especially intertidal ones, are affected by temperature and its rate of change in time and
space. Thermal stress affects the organisms' biochemistry and energy allocation, ultimately influencing the
community and ecosystem structures. Moreover, several studies have reported the vulnerability of intertidal
species to climate change and consequent distribution shifts (up to 50 km per decade) and abundance
changes. In this context, this study aimed to detect biochemical differences in field collected intertidal
gastropods when exposed to temperatures of 18-20ºC (April) and temperatures of 28-30ºC (June). Organisms
were collected in Cabo Raso during low tides occurring between 12:00 and 14:00h (hottest hours of the day).
Several thermal stress (Hsp70, ubiquitin) and oxidative stress biomarkers (glutathione-S-transferase,
superoxide dismutase, catalase, lipid peroxidation) were quantified in several species of gastropods. Results
showed that the species studied undergo biochemical changes when exposed to high temperatures in the field.
Hsp70 and ubiquitin are particularly responsive to thermal changes. Among oxidative stress biomarkers,
glutathione-S-transferase was particularly responsive to increasing temperatures. These results may be
indicative that the gastropods are currently under stress during summer heat waves.

Many marine organisms show a high phenotypic plasticity often related to environmental conditions, such as
wave exposure, substrate type and habitat. This high morphological variability can lead to species
122
misidentification with serious implications for monitoring activities and conservation policies, such as in the
MPAs. Molecular tools are right now useful to identify species but they are not always applicable for extensive
field sampling and monitoring living organisms, due to research time and costs. Some morphological traits
were used to distinguish two closely related species of limpets (Patella rustica and P. caerulea) in 8 sites
among 4 MPAs in the western Mediterranean (Portofino, Tavolara, Cabo de Palos and Port-Cros). Taxonomic
identifications were confirmed by the sequencing of the mitochondrial COI region that is a useful marker to
disentangle species. The two species significantly differed in their mean shell solidity, which is a measure of
how “ruffled” the borders are, in mean circularity and in the ratios height/longest diameter, height/area and
weight/longest diameter. Despite these differences appeared consistent, a large local morphological variability
was found. Morphometrics are a useful tool when species identification is challenging and to evaluate the
morphological adaptation in different environments.

In heterogeneous environments, individuals experience different combinations of physical and biological
pressures over small spatial scales. For many marine organisms with limited adult mobility, but planktonic
dispersal, localised adaptation may occur over an organism's life cycle through acclimation. Understanding the
plasticity of physiology through acclimation is vital in predicting species' vulnerability to climate change. In this
study we assessed local conditions on four sections (<500 m apart) of a tropical rocky shore to determine
whether differences in local conditions affect the physiology of the limpet, Cellana grata. Shore sections
differed in aspect, exposure and topography, and in biological characteristics such as levels of competition
(grazer density) and facilitation (barnacle cover). Using a bootstrapped principal component analysis, we
demonstrated that sections of shore differed significantly in terms of the relative contributions of the multiple
variables measured. As a measure of physiological acclimation, detachment temperatures of limpets from each
site were measured in the laboratory and higher detachment temperatures were found in limpets from shore
sections with greater physical stress and lower biological stress. These results demonstrate that physiological
limits can acclimate to local conditions over short temporal scales and uniform physiology should not be
assumed in species distribution or climate change models.

Connectivity between coastal and estuarine nurseries is a critical step in the life cycle of many fish species.
Larval immigration and retention, and their associated driving factors, will determine the success of nursery
recruitment. The recruitment of the common flounder Platichthys flesus to estuaries has been typically
addressed in many studies, but few have integrated the earlier planktonic life stages with the initial juvenile
stages. The present study investigated the interannual variability of flounder recruitment to the Lima estuary
(NW Portugal), including ichthyoplankton and recently settled fish data from several surveys conducted
between 2002 and 2013. This work has also identified the major environmental drivers in the recruitment of the
species to the estuary. Late-stage larvae arrived at the estuary between May and July. Recently settled
juveniles (<50 mm) were found restricted to the upper section of the estuary, showing a clear preference for
low salinity to freshwater habitat. Climate and hydrology were important regulators of the larvae immigration to
the estuary, where the settlement later occurred. Overall, this study has contributed to an improved
understanding of the recruitment mechanisms of the flounder, emphasizing the importance of considering both
planktonic and benthic ecology in fish population regulation and estuarine management.

Kelp species create complex habitats that provide essential resources, shelter and nursery grounds for many
marine organisms, mostly when present in dense stands (i.e., kelp forests). The importance of deep-water kelp
forests as source for recolonization of shallower areas after disturbance events has been stressed, however
the role and distribution of these unique deep habitats is still largely unknown. We aimed to infer the potential
distribution of deep kelp forests and to assess their degree of connectivity throughout the Western
Mediterranean and the adjacent Atlantic seamounts. Boosted regression trees (BRT) were used to address
which environmental variables (light, temperature, nutrients) shape the distribution of deep kelp and to predict
their potential habitat. The inferred distribution was validated with underwater video transects driven by a
remotely operated vehicle. The degree of connectivity between populations was inferred using Lagrangian
dispersal simulations based on a high-resolution ocean circulation model. Results showed that kelp ranges are
shaped by negative effects of extreme temperatures and positive effects of upwelling increasing nutrient
availability. Niche models predicted isolated favourable habitats throughout the study region, while the
simulations of dispersal estimated low connectivity among them. Furthermore, we reported the occurrence of
kelp species for regions that were to date not known to host them.

The study of larval connectivity allows for a better understanding of marine species dynamics, in particular in
coastal ecosystems as the Western Iberian Margin. Coastal ocean physical processes play a fundamental role
in the life cycle of numerous marine species. Hence, it is important to understand how their variability and/or
long-term changes affect(s) and/or bound(s) the development and survival of larvae. Numerical models of
124
ocean circulation can help to overcome the inherent difficulties of monitoring such complex dynamics, in
particular Lagrangian models coupled to regional ocean configurations. The period 2001-2011 is studied:
connectivity matrices are calculated and analyzed, in order to provide the spatial and temporal scales for the
supply, accumulation and connectivity of larvae, including and excluding diel vertical migrations, and relating its
patterns to wind forcing and the coastal circulation.

Mugil liza is distributed from Argentina to Venezuela and is considered an estuarine-dependent catadromous
species, with isochronal spawning. Reproductive migration from the estuary in south Brazil (32º S) towards the
sea occurs between May and June and the southern population spawns on offshore waters North of 29º S.
Eggs and larvae are neustonic and the transport and accumulation of the larvae toward the coast is a passive
process, determined by the circulation patterns of coastal currents. Juveniles (~20 to 30 mm TL) concentrate in
the surf zones in a pre-recruitment stage where they remain until they find the favorable conditions before
recruiting in Patos Lagoon Estuary - PLE (considered as the principal site of nursery for this species in the
Atlantic Coast). We analyzed the length-weight relationship of 420 individuals collected in the surf-zone and
the estuary. Daily otolith rings of 200 individuals also collected in the surf-zone and the estuary were analyzed.
Those individuals that remain in the surf-zone environment present a strong decrease in their growth rate until
they succeed to recruit into estuaries. This behavior seems to explain the constant recruitment of juveniles (20
to 30 mm TL) at PLE throughout the year.

This work compares the connectivity (estuary vs. surf-zone) and the latitudinal gradients in species diversity of
fish in three regions of Brazil (NE- 6ºS, SE- 23ºS and S- 32ºS). Between February-December/2011, monthly
collections were made using beach seines and environmental variables were registered. Fish were identified,
counted and multivariate analyzes (MDS-SIMPROF-SIMPER-CCA) were used to assess patterns in fish
assemblages. One hundred and forty one species were collected (belonging to 47 families). Similarity between
adjacent habitats is greater than between distant regions and samples could be grouped into three regions.
The NE was associated with higher temperatures/salinities, the SE with higher transparency and intermediates
temperatures/salinities, and the S with lower temperatures/salinities. Although the S region had low richness,
their ‘Average Taxonomic Distinctness’ was similar to the other two regions, with values near the mean (~ 92)
and inside the confidence interval. In SE and S regions, more fish were caught in the estuary than in the surfzone, whereas for NE the catches were higher in the surf zone than in the estuary. Estuaries showed the
highest richness in relation to surf-zone. Between regions, the similarity was lower for surf-zone and higher for
estuaries, with higher similarity between habitats inside the same region.

In higher latitudes of the northern hemisphere, anadromous fishes can act as biological vectors, moving
marine-derived nutrients into freshwater ecosystems during their reproductive migration. Much less information
is available on the potential role of marine and estuarine-related fishes as biological vectors in subtropical
latitudes. We investigated whether juvenile mullets (Mugil liza) might transport marine nutrients into the
125
freshwater food webs of coastal streams in southern Brazil (32°17' S and 52°15' W). To test this hypothesis,
we analyzed the stable isotope d13C and d15N in 10 basal production sources and 10 consumer species,
including juvenile mullets, at three sites (surf zone, lower stream reach, headwater reach) along a marinefreshwater gradient, Additionally, we analyzed the Sr:Ca ratios in otoliths of 14 juvenile mullets collected at the
surf zone and 12 collected inside the stream to describe patterns of habitat use. Overall, individuals caught at
surf-zone revealed no changes in their Sr:Ca profiles, but most individuals caught inside streams had a
decreasing trend in their Sr:Ca profiles suggesting they remained inside freshwater after colonization. We also
observed a significant decreasing trend in d15N and d13C values from the sea to the freshwater sites,
suggesting an importation and incorporation of marine-derived nutrients into the coastal stream.

The dusky grouper Epinephelus marginatus has a broad global distribution and is currently listed as an
endangered species at the IUCN Red List. This species has large commercial and ecological importance, but
only at the last decade were carried out the first studies about the bioecology of this species at its
southernmost limit of its distribution in the Southwestern Atlantic. Prior studies showed that immature
individuals (mean: 4 yrs) of dusky groupers inhabiting rocky jetties in the littoral region represents an important
incoming source for artisanal fishermen. In contrast, adults (mean: 8 years) are mostly found in offshore banks
15-25 m deep, which suggest that the littoral region is a growing area and the neritic is a reproductive site.
Other studies on its feeding ecology in this region (based on stomach content and stable isotopes) showed that
the species has an important role as top predators in these rocky habitats. However, future studies on the
residence time of immature individuals in the coastal area and connectivity between the littoral/neritic areas
using techniques as otolith chemistry and telemetry are fundamental to further understand the ecology of this
endangered species in the Southwestern Atlantic and help its fishing management and conservation.

Water is a main resource for environment, life and economic development. In Low valley Negro river,
productive development have benefited from irrigation systems with water harness from Negro river at the end
of estuary, on Guardia Mitre zone. This system supports the water needs for crops (horticultural items, dry
fruits and forage) and livestock (including sheep). At times water needs may not be supported by this system
and other sources like ground waters will be necessary. However producers do not know the physical,
chemical and microbiological quality of available groundwater and its aptitude for agricultural use. This work
aimed to research the groundwater quality and its connectivity with Negro river by classical analysis. Thirteen
sampling points were selected, in dry and irrigated areas. A multivariate analysis separated a group of
groundwaters with similar chemical parameters. It is necessary to extend groundwater research to characterize
zones according to their aptitude for agricultural use and management.

Understanding movements and habitat use patterns of different fish species within estuaries has major
implications for habitat conservation and management. Soft tissue stable isotopes (δ13C, δ15N) and otolith
elemental composition (Li:Ca, Mg:Ca, Mn:Ca, Cu:Ca, Sr:Ca, Ba:Ca and Pb:Ca) were used to evaluate
connectivity between two separate estuarine areas in summer and autumn for Pomatoschistus microps and
juvenile age-0 Dicentrarchus labrax. Distinct isotopic and otolith elemental signatures were found between the
two estuarine areas for P. microps and D. labrax, and in both sampling times. Differences in muscle stable
126
isotope signatures were a reflection of the isotopic composition of local food webs. High classification
accuracies to collection sites were achieved via otolith elemental signatures, and a combined analysis using
both muscle stable isotopes and otolith chemistry resulted in increased classification accuracies. Overall, low
site connectivity was found for both species within the same estuarine system. Ultimately, the use of two
distinct natural tags provided corroborative and complementary information on intra-estuarine connectivity and
habitat use at different temporal scales, whilst elucidating distinct ecological and environmental linkages.

Stable isotopes (d13C and d15N) were used to determine the different sources of organic matter supporting
fish species and fish connectivity in the Gironde estuary (France). Different producers, primary consumers and
nine fish species of three habitats in the downstream area of the estuary collected in July 2012 were examined.
All sources and invertebrates had significant (PERMANOVA) different isotopic signature between habitats.
Only sole S. solea presented distinct dual isotopic signatures among fish, indicating a higher fidelity to feeding
location for this species. Results indicated that fish had not been feeding exclusively in the habitat where they
were collected and high habitat connectivity for fish. As the base of the fish food web significantly differed
between habitats, the present study indicated the suitability of stable isotopes in tracing fish fidelity/connectivity
for opposite estuarine habitats distant from less than 10 kilometres. According to SIAR mixing model, organic
matter sources contribution were quite similar for each fish species, with a marine-derived POM dominance
(>75%); which has been related to the low intertidal surface. Only P. flesus and A. alosa utilised in greater
proportion freshwater POM. Present study provided a novel insight for future management of the Gironde in
the actual global change.

Baixo Vouga Lagunar has about 3000 hectares and is located in Aveiro district in the confluence of Vouga
River and Ria de Aveiro. Given its location it is constantly under the pressure of flooding and salt intrusion
which led it to be a case study of the scientific project ADAPTARia (PTDC/AAC-CLI/100953/2008). Baixo
Vouga Lagunar is known as a highly productive area for agriculture and is classified as a Nature 2000 network.
The agricultural plots are divided into bocage landscape and open fields. Beyond that it has a significantly reed
area which has been increasing in result of the salt intrusion destroying the soil structure. In the scope of this
project several proposals have been designed based in the international concept of Green Infrastructures
which resorts to nature in order to create ecologic, economic and social benefits, responding to the
environmental problems with an ecological and sustainable response. Facing climate change effects, the
strategies were divided into Adaptation and Control Measures, developed by a multidisciplinary team,
combining soft, mix and hard interventions. Through these proposals the recovery of former agriculture areas
is forecasted along with the increase of its biodiversity levels and the promotion of multiple uses within the
territory.

processes a numerical analysis was performed to the Portuguese Coast Operational Modelling System
(PCOMS) and several estuaries in the Portuguese coast. The PCOMS model is a fully 3D baroclinic
hydrodynamic and ecological regional model that covers the Iberian Atlantic front and that also provides
boundary conditions to estuarine applications. Both the estuarine and the PCOMS models are operated by the
Mohid Water model. The nutrient contributions were evaluated by calculating the fluxes from the estuaries to

nutrients were analysed by model results integration in boxes, residual circulation and their area of influence
was obtained by off-line lagrangian tracers simulations.

“ECORISK - Ecological risk assessment of oils and hazardous and noxious substances in the NW Portuguese
coast” is to carry out activities with children, and basic and secondary school students to increase their
knowledge and sensitivity regarding marine biodiversity, services provided by marine ecosystems, and the
need of protecting them against major treats such as pollution, climate changes and invasive species. Two of
the workshops organized so far were “Playing in the sea bottom” where children learned about marine
biodiversity and pollution through the creation of small sculptures representing sea species using debris
commonly found in the beaches, and an hands-on experiment entitled “Oil spill…and now?”, where the
children simulated an oil spill in bowls (using vegetable oil), its effects on birds and evaluated the effectiveness
of several clean-up measures. Several other activities have been carried out with a very positive feedback.

The Ria Formosa (South of Portugal) is a highly productive coastal lagoon, very important from both economic
and ecological viewpoints. It supports several economic activities that, simultaneously, depend on the health of
the ecosystem (e.g. tourism) and might be potential threats to its quality. Understanding the processes that
affect the productivity of this ecosystem is thus essential to support its sustainable management. The COALA
project aims to study the exchanges of nutrients, chlorophyll and particulate matter between the Ria Formosa
and the ocean and how this dynamics is influenced by the main forcings (e.g. tide), combining field surveys
and numerical modelling in a multidisciplinary approach. A duly validated hydrodynamic model, SELFE, and a
lagrangean model were used to study the influence of the environmental forcings on the dynamics of
exchanges lagoon – ocean. Several scenarios were simulated with different wind conditions, bathymetric
configurations and discharged flows from local wastewater treatment plants. Results suggest a considerable
influence of wind direction and bathymetry in the amount of particles exported out of the system at short time
scales. The analysis of transport patterns of potential pollutants (nutrients among others) discharged by the
wastewater treatment plants contributes to support the management of the Ria Formosa.

resources value are of recognized importance, as it may encourage local communities to become themselves
promoters of sustainability through the use and dissemination of good practices. To promote this, participatory

development of the eco-social dialog and the promotion of active participation of local communities, the

human and social dimension, contributing to conflict minimization and resolution. A Governance Model for
Marine Park Professor Luiz Saldanha (Arrábida), replicable and adaptable to other Marine Protected Areas
was collaboratively constructed with social and institutional actors. Following studies previously developed in
Australia and the United States (California), the project Value of Waves and Ocean Culture in Portugal added
to the economic component the environmental, social and cultural dimensions, and aimed towards the
development of a collaborative model of governance for management of natural and cultural resources. The
objective of this methodology is to sustain and strengthen decisions related to the development and
conservation of coastal areas to be replicable in similar areas.

Fifteen intertidal macroalgae of the Tagus estuary were characterized by laser induced fluorescence (LIF).
Based on their LIF emission spectra, it was possible to divide them into two groups: red and green/brown
algae. The LIF emission spectra of red macroalgae were characterized by three bands with emission maxima
between 577-583 nm, 621-642 nm and 705-731 nm, while green and brown algae showed one emission
maxima in the red region (687-690 nm) and/or one in the far-red region (726-732 nm). Differences in
photosynthetic mechanisms, especially in light harvesting pigment assemblages and chloroplast structure are
the main reasons for the variance between the LIF spectra of the three groups of macroalgae. Furthermore,
increased water loss during low tide exposure of intertidal green macroalgae affected the measured LIF
spectra, leading to a decrease in the red/far red chlorophyll fluorescence ratio (F685/F735), ultimately causing
a shift in the fluorescence peak maxima to 732 nm under extreme desiccation. This study shows that LIF is a
valuable tool for the spatial analysis and resource management of estuarine intertidal areas colonized by
macroalgae.

The growth of the Marine Renewable Energy (MRE) industry requires the development of offshore large-scale
projects, possibly combining various devices (e.g. wind turbines and wave converters) or activities. The
development of these large-scale projects, and their addition to other anthropogenic activities o.shore, is
accompanied by environmental concerns. These concerns are reported based on a classification scheme
identifying stressors, receptors, effects and impacts. Although the potential environmental effects are identifed,
there are large knowledge gaps regarding the corresponding (positive and negative) impacts. In that context,
the development of ofshore MRE requires the implementation of fit-for-purpose monitoring activities aimed at
environmental protection and knowledge development. It is suggested to adopt standardized monitoring
protocols for the enhanced usage and utility of Environmental State Indicators (ESI). Towards this objective,
the use of the “Frame of Reference” (FoR) approach is advocated since it provides guidance for the definition
and use of coherent set of ESI. Examples of application of the FoR are provided considering a virtual MRE
project. It is found that although some efforts are required for its implementation, the FoR can improve the
management of specific environmental issues and should be tested against real cases.

Scientific data collection: a tool towards water quality assessment in Portuguese estuaries with
potential for aquaculture

Portuguese Water Quality Policy, outlined by Water Framework Directive, requires the classification of water
bodies for aquaculture usage by establishing water maximum recommended values (MRV) and maximum
130
admissible values (MAV) for several parameters described in Decree-Law no.236/98 for estuarine brackish
and salt waters. In this study, eight Portuguese estuaries (Minho, Vouga, Mondego, Tagus, Sado, Mira,
Guadiana and Ria Formosa), identified as having potential for aquaculture activities, generated about €57
million in 2013, corresponding to a production of 8,000 metric tons. However, this activity involves some
environmental concerns regarding fish farm discharges and consequently the need of water quality
environmental standards. For the initial water quality assessment physical-chemical data, collected from
several research programs, was compiled from the last two decades for the referred estuaries. The analysis of
data revealed Tagus, Sado and Vouga to be the most studied systems, accounting for 60% of global data
(N=24,882), while Mira and Ria Formosa were the less studied. Sampling surveys were mainly undertaken in
spring and autumn, with temperature, pH, ammoniacal nitrogen, nitrate and total suspended matter
representing 51% of the most sampled parameters. This approach allowed us to identify existing gaps in the
spatial patterns and temporal trends of the data, enabling a better planning of future monitoring and research
activities.

The Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD) are key
legislative actions developed by the European Union in order to protect the aquatic ecosystems. One of the
concerning pollutants in these directives is tributyltin (TBT), a biocide present in aquatic antifouling paints and
considered the causative agent of imposex in gastropods. In order to integrate TBT pollution assessment in
these legislative frameworks, two estuarine areas were used as cases studies: the estuaries of Minho and
Lima (NW Portugal). The levels of imposex were surveyed in two gastropod species (Nucella lapillus /
Nassarius reticulatus) and a 28-day bioassay was performed, exposing the netted whelk to sediment collected
from sites around both estuarine areas. Imposex levels evidenced different scenarios for each estuary. While
in Minho the index that measures the imposex severity (VDSI) ranged from 0. 55 to 1.63, in Lima varied
between 1.28 and 3.38. The sediment bioassay confirmed the same pattern of contamination, as TBT
androgenic activity was significantly detected only in the vicinity of Lima harbour area. The development of
ecological quality ratios (EQR), as demanded by WFD, are here discussed in order to apply this biomarker tool
to the definition of ecological status.

coastal global change. The vulnerability of RMS results from a combination of their natural complexity as well
as the wide range of human activities in these systems. The assessment of RMS vulnerability can be
evaluated through appropriate indicators. In this work, the general pressures affecting the vulnerability of RMS
are addressed and indicators for their vulnerability are proposed, based in a multi-criterion approach, including
natural hazards, hydrological, morphological, ecological, ecosystem-services and socio-economic indicators,
thereby integrating social, environmental and economic components into a coherent framework. The use of
indicators to understand complex processes in RMS can make an important contribution for the design of
science-based management strategies. Identification and monitoring of the locally appropriate key indicators is
relevant for assessing the state of the RMS and implementing management plans to improve resilience,
sustainable development and Human welfare.

Overview of scientific publications on water quality for Portuguese estuaries – a decision support on
water policy topics
Oliveira AP, Gonçalves C, Nogueira M
Corresponding author: [email protected] (AP Oliveira)
Economic indicators reveal Portuguese aquaculture activity with a prospective growth, being estimated a
double production by 2015. With such development, a range of potentially controversial issues are emerging,
131
which could significantly impact the future success of the activity. Hence, scientific publications addressing
aquaculture topics are imperative, which will facilitate policy decisions. Therefore, a review of literature on the
water quality, focused on physical-chemical parameters, was made for eight Portuguese estuaries with
potential for aquaculture on their catchments. From the revised literature between 1995 and 2013 (N=139),
70% was published in indexed journals, mainly in Estuarine, Coastal and Shelf Science and Hydrobiologia.
The remaining 30% falls into grey literature, which is partitioned between Technical Reports (20%), Thesis
(4%), Scientific Seminaries (3%) and Not Indexed Journals (2%). Chapters in books was the least used source
for the dissemination of scientific data. There was an upward trend in publication outputs, more noticeable from
2003, being the year 2007 the most productive. Guadiana, Tagus and Vouga estuaries were the most reported
in the literature, with an overall of 78 publications. Concerning Minho, Sado and Mira, publications were scarce
(N=23), mostly belonging to grey literature. This compilation points to the need for more scientific publications
on Portuguese estuaries, which will improve management practices and effectiveness of environmental
policies.

Corresponding author: [email protected] (RMCP Pessoa)
The recreational carrying capacity (RCC) of Ajuruteua beach was analyzed in 2012 during July (summer
vacation) and the Easter (rainy season) and Brazilian Independence long bank holidays (dry season), during
four-day samples (Friday-Monday). The number of people was counted between 08:00 h and 18:00 h along of
three zones: (1) bars and restaurants, (2) intertidal zone, and (3) surf zone. At Easter, the most popular days
were Friday and Saturday and RCC values of 7.07-72.17 m² per person in zone 1, 53.91-436.67 m² in zone 2,
and 9.76-400 m² in zone 3. In July, Saturday and Sunday were the most popular days and RCC values of 2.13168.39 m² per person in zone 1, 16.84-190.48 m² in zone 2, and 1.26-200 m² in zone 3. In September,
Saturday and Sunday were the most popular days and RCC values of 8.15-336.78 m² per person in zone 1,
5.31-888 m² in zone 2, and 3.6-400 m² in zone 3. Significant differences were found between July and the
rainy and dry season holidays and during the most visited days. There is a clear need for the implementation of
adequate coastal management strategies in order to improve the quality of local tourism activities.

The coastal ecosystems of the Northwestern Iberian Peninsula constitute a very productive system, sustaining
important fishing and aquaculture resources. This is mainly a consequence of the subsurface nutrient input
from the spring-summer coastal upwelling. On the other hand, the coastal ecosystem receives nutrient inputs
from the continent and the atmosphere, which are thought to have an influence on the productivity and organic
matter cycling. These inputs are expected to increase over the next decades, in parallel to changes in physical
forcing related to the intensity of the upwelling system. In this respect, a multidisciplinary observational and
modelling approach presents interesting potentialities to understand the current cycling of elements in the
coastal ecosystem, and sets the basis to predict changes in the future. In this work, we present the
implementation of a high resolution coupled physical-biogeochemical ocean model to the coastal ecosystem of
the Northwestern ecosystem of the Iberian Peninsula. We used ROMS (Regional Ocean Modeling System)
hydrodynamics coupled to PISCES (Pelagic Interaction Scheme for Carbon and Ecological Studies)
biogeochemistry (which includes several nutrients and two phytoplankton functional groups) to run a realistic
simulation for one year. Model results were compared to observations for this period in order to evaluate model
performance.

The present work considers the role and relevance of the practice of collective learning processes and public
participation, as tools for decision making in environmental management. Coastal environments management
involves the economical use of ecological systems in diverse ways without ensuring the commitment of users,
and often, affecting negatively the environmental quality. The coastal areas are losing their natural
characteristics as demand grows for new spaces to increase production, for urban areas spread to
accommodate population growth and as urbanization processes are intensified. This happens without
involvement of the responsible and receptor agents in the decision making processes underlying these
changes. Inspiring experiences of participatory methodologies practices in building up collective knowledge are
presented, aiming to articulate scientific and local knowledge, relevant for the decision making processes in
coastal protected areas and areas of tourism expansion in Brazil and Portugal. Successes and lessons learned
from these experiences are central in this reflection. It is debated further how these methodologies can be
more thoroughly applied, avoiding drawbacks while potentiating the frequently forgotten human resources of
these areas.

An overview of existing European approaches for beach management
Semeoshenkova VS, Newton A
University of Bologna, Ravenna Campus, Italy
Corresponding author: [email protected] (VS Semeoshenkova)
Beaches are under significant pressures, both natural and anthropogenic, exacerbated by climate change and
intensive coastal development. Coastal erosion, deformation of coastal dunes, overcrowding, excessive litter,
reduced water quality, and negative effects on biota are among the most common problems of the modern
European coastline. The societal response to these problems results in different approaches of beach
management in Southern Europe. These include coastal protection, to combat coastal erosion, as well as
beach awards and quality systems aimed to support the recreational value of beaches. Analyses of existing
beach management approaches in Spain, Italy and Portugal reveal that poorly planned management solutions
lead to the intensification of the problems. Such management actions are often an emergency response to
problems, and not supported by the adequate knowledge of marine process, coastal vulnerability and
environmental consequences. In contrast, successful experiences in beach nourishment and quality awards
have enhanced the attractiveness of beaches for the tourism and leisure sectors. Knowledge of the available
options and examples of best and poor practices contributes to proper onsite management, and thereby
sustainable development of coastal areas.

MARLISCO–Marine Litter in Europe Seas: Social Awareness and CO-Responsibility is a FP7 project
developed in four European Regional Seas, by a consortium of institutions from 15 countries including
Portugal. Its main goal is to raise public awareness, facilitate dialogue and promote co-responsibility among
the different actors, in order to inspire changes in the attitudes and behavior in society and share a vision for
the sustainable management of marine litter. Departing from an extensive collection of information about
marine debris (distribution, impacts, legislation, and best practices) and a survey on the stakeholders'
perceptions on marine litter, the project involves all sectors related directly or indirectly to marine litter. Marlisco
is supported by a core of initiatives, namely National Forums, a European Video contest for youngsters, an
Exhibition and other educational activities to raise awareness among the wider public. So far, more than 6000
people were involved in Marlisco activities and more than 600 students participated in the Video Contest.
Changes in the perception on Marine litter are to be evaluated to assess the level of success in the changing of
attitudes and behaviors of the ones involved.

One of the main problems in Amazon beaches is the lack of public sanitation, which results in bathing waters
contamination by bacteria, such as coliforms, and unpleasant sights and odors. This study analyzes water
quality in 3 estuarine beaches (Colares, Marudá and Murubira) in the Amazon region for bathing conditions. All
beaches present numerous outlets of sewage and it is expected that, in spite of the high dynamics of the area,
they can have a significant impact on water quality. The experimental study was done during high-use periods
(July 2012 and 2013). The highest level of bacteriological contamination was recorded in 2012, when rainfall
level was highest. Obtained results showed that a large number of water samples (between 40-60 %)
exceeded the concentration threshold for not-recommendable for bathing. In some cases, these values were
registered in zones with the highest concentration of beachside facilities and number of beachgoers. Peaks of
contamination were recorded during high tides and the beginning of the ebb tides, when the tides reach the
level of the outlets of sewage in the intertidal zone. According to obtained results, a differentiated strategy for
water monitoring and bath management has been designed to improve users’ safety.

Coastal ecosystems are subjected to a wide range of anthropogenic pressures, including variations to global
changes, environmental contamination, among others. Several of them cause changes in water parameters
and decrease its quality. In the present study, a monitoring programme including 15 water parameters was
carried out for one year (monthly sampling) in the estuary of Minho River (NW Iberian Peninsula), which is one
of the three Portuguese estuaries included in the programmes LTER - Portugal and LTER - Europe. The
results were analyzed and compared with data obtained previously and available in the literature, contributing
to increase the knowledge on long-term variation of the system and its responsiveness in relation to climate
variation and other pressures.

Halophytes are vegetal species with morphological and physiological adaptations, which grow in alkaline or
saline soils. In these unfavorable conditions, tolerant plants often develop a powerful antioxidant system which
involves several components [1]. Investigation of these understudied species may have economic implications
in the field of biotechnology applied to health, agricultural, pharmaceutical and cosmeceutical areas. Twelve
halophyte species were collected from the Portuguese coast. Successively they were dried and then extracted
with different solvents. The ethyl acetate fractions obtained from methanolic extracts were the most active and
the total phenols content, radical-scavenging activity, reducing power and lipid peroxidation inhibition [2] were
evaluated. Results showed the highest content of polyphenols in Limonium ovalifolium, Limoniastrum
ferulaceum, Aster tripolium and Salsola soda extracts, while Halimione portulacoides showed the lowest. L.
ovalifolium and L. ferulaceum, belonging to same family, had the highest radical-scavenging activity and
reducing power, while almost all analyzed species showed lipid peroxidation inhibition higher than 50%.
Results indicated that halophytes can be considered an important source of natural antioxidants.

The Portuguese National Integrated Coastal Zone Management Strategy - ENGIZC(D.R.2009) criticized as a
«document with low practical implementation; similar to previous ones published since 1998, plenty of ‘good
intentions’ meanwhile bad practices and errors are portrayed»(Quercus, 2009) at territorial level, and with a
134
total absence of accountability within the Portuguese territorial planning system as assuming a reactive and
passive role (Veludo, 2005). The increasing complexity of territorial issues (sea level rising) and a growing
claim for space is to be analyzed within the actual state-of-the-art of the national institutional decision-making
framework, taking in account two important contributes: (1) SIA- the call for an Integrated coastal zone
management (ICZM) that connects with social impact assessment (Vanclay, 2012); (2) from NUDGE to
BUDGE- the positive contribute of behavioural economics to inform policy. Its use has recently been captured
by those who advocate nudge interventions, which are essentially «anti-regulation (…). Thus, it is proposed
that a new approach be developed – budge – or in longhand, behavioural economic-informed regulation
designed to budge the private sector away from socially harmful acts.» (Oliver, 2013). Finally, a debate will be
held on the potential to innovate our ENGIZC considering these contributes.
