A
s Minister of the Environment, it is
a great pleasure for me to welcome
participants to the 30th Congress of the
International Association of Theoretical
and Applied Limnology 2007. We are
proud to be part of this conference. This
event provides an excellent forum for all of
us to share our knowledge and expertise.
Water is a natural resource that
is of prime importance to the health of
Canadians and our economy. More than
ever, we make it a priority to conserve our
freshwater, and to work with other governments
within and outside Canada to achieve this goal.
In recent months, Canada has committed to do its part
to preserve and protect our rivers, lakes and oceans for future
generations through a National Water Strategy. This strategy
also includes commitments to better manage our wastewater
treatment systems.
Water is a shared resource that must be managed
responsibly worldwide. With 61 countries represented at this
conference, we have an excellent opportunity to work together to
address issues and propose solutions for clean, safe and healthy
water. Sustainable development is at the heart of our concerns
to ensure sound use of freshwater for the benefit of all citizens
around the globe.
I wish you all an excellent conference.

À
titre de ministre de l’Environnement, j’ai le grand plaisir de
souhaiter la bienvenue aux participants au 30e congrès de
l’International Association of Theoretical and Applied Limnology
de 2007. Nous sommes particulièrement fiers d’être ici, puisque
cet événement nous offre à tous l’occasion de partager nos
connaissances et expériences, et d’échanger.
L’eau demeure une ressource naturelle d’une importance
primordiale, tant pour la santé des Canadiennes et des Canadiens
que pour notre économie. Plus que jamais, nous faisons de la
conservation de l’eau douce une priorité, et c’est de concert
avec les autres gouvernements, tout aussi bien à l’intérieur qu’à
l’extérieur du Canada, que nous travaillons à la réalisation de cet
objectif.
Au cours des derniers mois, le Canada s’est engagé, dans
le cadre de sa Stratégie nationale sur l’eau, à faire sa part pour
conserver et protéger nos lacs, rivières et océans pour le bénéfice
des générations futures. Qui plus est, cette stratégie comporte
des engagements en vue d’assurer une gestion plus efficace des
systèmes de traitement des eaux usées.
L’eau est une ressource partagée, que le monde entier se
doit gérer de façon responsable. Aussi, puisque près de 61 pays
participent au présent congrès, nous avons là une merveilleuse
occasion de nous pencher sur cette préoccupation et de proposer
des solutions qui nous permettront de garder notre eau propre,
salubre et saine. Le développement durable figure au cœur même
de notre préoccupation d’assurer une saine utilisation de l’eau, et
de veiller aussi d’autant à ce que tous les habitants de la planète
puissent bénéficier de cette ressource.
Je vous souhaite un excellent congrès.
L’honorable John Baird
Ministre de l’Environnement

WELCOME LETTERS
Dear Friends,
For many of you, coming to the
Montreal Congress is part of the
ritual of being a SIL member,
a
triennial
pilgrimage
to
the frontiers of international
limnology. Since it has not been
in North America in nearly 35
years, it is likely that many of
you will experience here their
first SIL meeting. Either way,
the Organizing Committee of
the 30th Congress has made
sure to maintain the great
traditions of SIL while innovating
on several fronts. Here is a synopsis of the coming week.
Over the next few days, nearly 1150 presentations will be
given by scientists coming from over 60 countries from
all five continents. This rather jam-packed programme is
organized into 75 different sessions covering the
entire spectrum of limnology, from microbial ecology to
limnological remote-sensing from space. As an inherently
multidisciplinary field, the scientific programme includes
sessions exploring the many bridges between biological,
chemical and physical limnology. We have developed a
new activity for SIL, called the WaterWorks Forum, where,
each day at lunch time, panels of international experts will
discuss the challenges of integrating limnological
knowledge in a more general societal context, with
governments, industries (forestry, mining, and hydroelectric), environmental consultants and the many users
of lake resources.
For the first time in SIL’s history, the Montreal Congress
will be a green congress. This may seem just a fashionable
thing to do but we have worked very hard to remain true
to our words. By adopting a nearly complete paper-free
approach early in the organization of the Congress, we
generated enough savings to purchase and oversee the
planting of more than 7000 trees necessary to compensate
for the nearly 2000 tonnes of CO2 equivalents. These trees
will be planted within the watershed of a lake known to
experience cyanobacterial blooms with the purpose of
reducing its external phosphorus loading. We have
provided each of you with reusable water bottles in a
delegate bag made out of recycled banners from the city
of Montreal. Come and visit the booth in the exhibit hall to
find out the many other actions we have taken to reduce
the congress’s footprint on the environment.
2
Lastly, we have created several activities directed at the
new generation of limnologists. Every night, at the cœur
des sciences de l’UQÀM, students will be able to gather, in
a casual setting, in a series of forums to discuss the many
issues students have to face when beginning a career in
science and limnology in particular.
Above all, as I indicated in the last SIL circular, a good
congress is a congress one leaves with a sense of having
learned something new, of being closer to the scholar we
wish to be. I sincerely hope that our efforts in organizing
this meeting will facilitate the level of scientific exchange
that is necessary for the progress of our discipline.
Bon congrès !
Yves Prairie
Chair, Organizing Committee
Welcome to the 30th Congress
of SIL – the International
Association of Theoretical and
Applied Limnology. We expect a
very large number of limnologists
to attend this important and
exciting meeting in Montreal.
The meeting is important, not
only for the exchange of scientific information about inland
waters internationally, but also
because we will be charting SIL’s
activities and programs into the
future.
I look forward to a scientifically-productive meeting, to renewing friendships and to greeting you during the week in
Montreal.

FUTURE PERSPECTIVES FOR LIMNOLOGY IN
THE CONTEXT OF THE LAKE BIWA STORY
13:00 – 15:30
Public Lecture
“Mieux connaître nos lacs
et cours d’eau”
Lake Biwa is the largest lake in Japan, and it is
considered one of the most preciouslakes in the
world because it provides life-sustaining water
to almost 14 million people. This lake is also
well known for the long-term and/or intensive
research activities focused on it by numerous
researchers during the last 60 years. Since the
major international joint project, BITEX (Biwako
Transport Experiment),” in 1993, we have
devoted ourselves to developing new high
technology-based instrumental tools such as
the AUV (Autonomous Underwater Vehicle),
and have been able to report on a number of
previously unknown phenomena occurring in
Lake Biwa. Here we present the Lake Biwa story
based on the analysis of long-term data
accumulated over 60 years and the recent
changes due to global warming. Our
perspectives on the future direction of
limnology in Asian countries are also given.

LIMNOLOGY AND THE POST-NORMAL
IMPERATIVE: AN AFRICAN PERSPECTIVE
Dr. Kevin Rogers, Centre for Water in the
Environment, University of the Witwatersrand,
South Africa
Redefining limnology requires that we look to
our roots, examine our present and innovatively
look forward to an exciting future. South Africa
is one country that has given limnologists such
an opportunity. Our experiences may serve SIL
well. The Society’s roots are clearly “Theoretical
and Applied Limnology” but the Verhandlungen
show we are presently dominated by empirical
science with very little innovative exploration
of theoretical concepts, or of the imperatives
and practices of application. There is increased
multi-disciplinarity but research remains
dominated by “normal” science that avoids type
1 errors, assumes linear cause and effect and
is focussed on “wet” geographic regions. Given
that globally the condition of aquatic systems
continues to decline, we can hardly claim
success in the bigger scheme of things. More
limnologists need to add more, and more
appropriate, strings to their bow; theoretical,
research, knowledge interfacing, and
decision-making “strings”. Redefining limnology
will also find much support in paradigms of
“post normal enquiry”, “complex adaptive and
social-ecological systems”, “adaptive inference”,
and “action research”. In South Africa we have
found the paradigms useful but not sufficient,
unless embraced through the cultural ethic of
“Ubuntu” (Nguni) which has good analogies in
“Ba”(Japanese) and Cynefin (Welsh).

GLOBAL LIMNOLOGY: UP-SCALING
AQUATIC SERVICES AND PROCESSES
TO THE PLANET EARTH
By Dr. John Downing, EEOB, Iowa State
University, USA
Lakes, ponds, rivers, streams, and wetlands are
important drivers of Earth’s environment and
economy but their global role has been ignored.
Historically, limnologists studied aquatic
ecosystems as discrete entities embedded
within local environments and as biogeochemical
subordinates of watersheds. Comparative
limnology now exploits discrete qualities of
waters to create predictive relationships that are
amongst the world’s most successful ecological
theories. Predictive limnology serves both
science and society by deducing the behavior of
individual systems from general patterns.
Despite these strengths and the importance
of limnological resources, the global role of
limnology is neglected both by limnologists and
by analysts of the global environment. This is
due to limnology’s lack of global focus, the
assumption that the relatively small area of
continents covered by water means small
importance, and the paucity of appropriate
scaling rules and approaches for limnological
ecosystems. To encourage Earth’s limnologists
to take their rightful place in the global arena,
I survey the process of global science, outline
requisite scaling rules and needs, summarize
procedures for making global estimates, list the
most urgent variables in need of up-scaling, and
show that the intensity of limnological services
and processes makes them disproportionately
important at the global scale.

BIODIVERSITY CONSERVATION IN
AFRICAN WATERS: LESSONS OF THE LAKE
VICTORIA BASIN
By Dr. Lauren Chapman, Department of Biology,
McGill University, Canada
Freshwater systems have suffered some of
the most intense human impacts over the past
century. The result has been a massive reshaping of fish communities, with the pace of change
quickening in the tropics. In Africa, fish catches
have declined drastically; forests, crucial
regulators of surface water hydrology, are being
rapidly cleared; and pollution of surface and
ground water has become a serious threat. In
addition, introductions of exotic species have
lead to unprecedented changes in freshwater
communities, the most notable example being
Lake
Victoria, the largest tropical lake and Africa’s
most important source of inland fisheries
production. After it was fished down in the first
half of the 20th Century, Lake Victoria (and
other lakes in the basin) became home to a
series of introduced food fishes, including the
predatory Nile perch, Lates niloticus. A dramatic
increase in Nile perch in the 1980s coincided
with the disappearance of many species including ~40% of the estimated 500+ species of
endemic haplochromine cichlids. Other fishes
persisted with Nile perch at much reduced
numbers, some of which have resurged over
the past decade in response to intensive
fishing of Nile perch. And, a few species have
actually flourished with the invader including the
introduced Nile tilapia, a species that now forms
a critical component of the fishery. Understanding mechanisms of persistence, resurgence, and
prosperity of some species in response to
the Nile perch invasion is critical to both the
conservation of the remnant faunas and
sustainability of the fishery.
In this lecture, I review key lessons learned
from the Lake Victoria region that highlight
both the vulnerability and lability of native and
introduced species in the face of environmental
change. First, I discuss mechanisms that have
fostered persistence of native species, in
particular the use of structural and physiological
refugia in modulating invader impacts. Second,
I explore cascading effects of Nile perch on the
trophic structure of invaded systems. Third, I
consider the consequences of faunal collapse
and recovery on resurging species highlighting
evidence of phenotypic change in response to
both Nile perch predation and refugial selection
pressures. I end with the most poignant
lesson of Lake Victoria; the close link between
biodiversity conservation and the maintenance
of a sustainable fishery.

THE INTERFACE BETWEEN EVOLUTION AND
ECOLOGY: GENETIC DIVERSITY MATTERS
By Dr. Luc DeMeester, Laboratory of Aquatic
Ecology, University of Leuven, Belgium
Evolutionary biology and ecology have largely
developed as separate disciplines, each with
their own methods and approaches. This
27
Thursday, August 16 | 30th Congress of the International Association of Theoretical and Applied Limnology
development was largely inspired by the
prevailing view that evolutionary processes
operate at a different temporal scale than many
ecological processes. There is, however, rapidly
growing evidence for rapid evolutionary
responses, and this may have a strong impact
on our view on the dynamics of ecological
interactions. Considering evolutionary responses
may be very important when dealing with the
major environmental challenges met by the
biota in our increasingly human-dominated
world. Anthropogenic stress caused by
pollutants, climate change, the spread of exotic
species, etc. indeed impose very strong selection pressures on natural populations, and it is
thus likely that the ecological response to these
stressors will be strongly influenced by
concomitant evolutionary responses. In this
lecture, I first want to substantiate the above
reasoning with evidence of rapid micro-evolutionary changes using studies on freshwater
organisms as an example. I will then present
evidence accrued so far demonstrating a
feedback of micro-evolutionary responses on
the ecology of populations and on community
assembly. I will discuss the need for further
understanding the impact of evolutionary
responses to environmental change on
the distribution patterns of organisms,
biotic interactions, community ecology and
ecosystem functioning. I will then introduce the
emerging field of evolution in metacommunities
as a framework in which ecology and evolution
can be integrated in an encompassing way,
likely to yield new views on how organisms
respond to environmental change. Finally, I
will consider different promising approaches
to studying the impact of micro-evolution and
genetic diversity on ecology. Amongst others,
I will point to the need of carrying out
experiments quantifying the impact of
evolutionary responses on ecological
interactions.
I will discuss the limits of classical population
genetic studies, the importance and limits of
quantitative genetic studies, and the promises
of ecological genomics to potentially circumvent
those limitations in assessing the impact of
genetics on the dynamics and structure of
natural populations. Although the theme
addressed is general, the examples and
studies that I will use will be drawn from
studies on freshwater systems. As a matter
of fact, freshwater systems and model
organisms have features that make them
particularly good candidates to push this
important field of research forward.

THE IMPORTANCE OF SCALE, CONNECTIVITY, AND INCENTIVES IN CONSERVATION
PROGRAMS: THE CASE OF EXOTIC SALMONIDS OF PATAGONIA
By Dr. Miguel Pascual, Centro Nacional
Patagónico (CONICET), Chubut, Argentina
The list of “most wanted” aquatic alien species is
dominated by accidentally introduced organisms
that have already taken over large areas of the
world, producing millions of dollars in damages.
Naturally, the introduction of such pest species
is condemned without a trial, and science and
management efforts are geared towards elimination, containment, and prevention of future
infestations. Meanwhile, an alternative list of
aquatic organisms is actively traded around
the World, for food, fun, or aesthetic reasons.
The introduction of such commercial species
divides the waters, providing textbook examples
of the conflicts between human development
and nature conservation, and straining the
limits of sustainable development. Questions
arise: Are there win-win situations to be found
between production and the integrity of nature?
How can science and management promote
such win-win situations?
In this conference I attempt to provide some
answers to those questions by analyzing three
case studies of exotic Salmonids in Patagonia:
trout aquaculture in shallow fishless lakes,
trout recreational fisheries in lakes and rivers,
and marine net pen salmon aquaculture. For
each case study, I will review our current state
36
of knowledge, identifying major uncertainties.
I will also analyze the positive and negative
impacts brought about by exotic Salmonids,
discussing the prospects for finding win-win
situations. In the end, I will propose that three
interrelated properties of these case studies,
scale, connectivity, and incentives for
conservation, determine our ability to identify
and promote such win-win situations. I will
present my views on how science and
management can help to promote such
situations.

TAKING THE BIOGEOCHEMICAL PULSE OF
THE RIVER CONTINUUM
By Dr. Diane McKnight, University of
Colorado, USA
Approaching questions of aquatic biogeochemistry from the perspective of “hotspots” and/or
“hot moments” allows for integration of these
results within the broad concepts of aquatic
ecosystem function. This approach also allows
for making connections to the dynamic
chemistry of the diverse reactive constituents
of interest to limnologists. One example is the
role of sunlight in determining the structure
of stream ecosystems, not only by controlling
photosynthesis, a theme of the River Continuum
Concept (RCC), but also by driving photochemical processes. These photochemical processes
can transform nutrients, dissolved organic
material and many trace constituents. Studies
have shown that direct photochemical
processes influence the chemistry of the DOM
pool, changing its bioavailability and its
reactivity with trace metal and organic
contaminants. From a biogeochemical
perspective, the noonday sun irradiating a
stream or river reach represents a “hot
moment” that can have a sustained ecological
effect through the rest of the diel cycle. The
hydrologic transport of these reactive photochemical constituents to downstream reaches
and to adjacent reducing environments, such as
hyporheic zones, may influence ecosystem
function. Thus, the chemical diversity and
biogeochemical reactivity of many important
chemical species in stream ecosystems are
dynamic. The changes occurring over a
day-night cycle are superimposed upon
seasonal changes in light regime and in
hydrologic regime. Incorporating these dynamic
processes into the broad scale of the RCC and
into monitoring approaches may be useful in
understanding the current effects of the
substantial changes in water quality, land use
and hydrologic regime.

WaterWorks Forum
The WaterWorks Forum: Bringing the
Actors Together
Water is the source of all life on Earth. Our
usage of water, however, greatly transcends that
of our biological needs and is a critical resource
in many aspects of our economy and society.
For the first time in SIL congresses, we present
a series of four lunch-time panel discussions to
integrate, in a more direct format, the services
that limnological knowledge and expertise can
offer to our economy and to society in general.
The following four themes have been selected:
Monday, August 13
13:30 - 14:15, Room 519A
AGRICULTURE, LAND USE AND
WATERSHED MANAGEMENT
With the increase in population density, in
agricultural production, and of different land
usetypes, the use of water resources are constantly intensifying. The purpose of this WaterWorks Forum is to explore ways to integrate the
socio-economic development and the integrated
management of water, territory and other related resources.
◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦
Tuesday, August 14
13:30 - 14:15, Room 519A
KNOWLEDGE AND TECHNOLOGY
TRANSFER: THE ROLE OF ENVIRONMENTAL
CONSULTANTS
Environmental consultants play a major role in
transferring fundamental limnological knowledge
into the context of economic development. Furthermore, consultants contribute their expertise
to the development of technologies and “handson” methods that protect the environment.
This forum aims at exploring better ways that
state-of-the-art science can be efficiently
transferred to consultants and to the end users.
◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦◦
Thursday, August 16
13:30 - 14:15, Room 519A
ENERGY AND HYDROELECTRICITY:
PRODUCING ENERGY WHILE MAINTAINING
ENVIRONMENTAL FLOWS
The installation of dams to control flow or
generate hydroelectricity induces, to varying degrees, physical changes to waterways, which in
turn can cause impacts on aquatic ecosystems.
This Forum is aimed at debating the emergence

NATURAL RESOURCES (MINES, FORESTRY)
AND THEIR LIMNOLOGICAL INTERFACE
Freshwater is widely used in industrial activities,
including those involved in the exploitation and
development of other natural resources sharing
the same landscape. In many landscapes of the
world, water bodies intersects with both mineral
and forest resources. Panelists in this Forum will
discuss which exploitation practices can better
maintain or protect the ecological integrity of
lakes and rivers.

claim Lake Memphremagog contains a
reptile-like monster named Memphre
(or Memphré), which has received
sightings since the 18th century and
continues on in the folklore of the
area in a similar vein as the Loch Ness
Monster. It is claimed that Memphre
has been spotted as recently as 2000.

Retrace the steps of the first explorers
of Quebec’s territories on this epic trip
on the Saint-Maurice river, one of the
largest tributaries of the Saint-Lawrence River. Aboard unique Rabaska
canoes, you will enjoy the striking
wildlife and landscape of this region.
The Saint-Maurice River is a river in
central Quebec which flows south 523
km from the northern Gouin Reservoir
to empty into the Saint Lawrence River
at Trois-Rivières, Quebec. During the
18th century, early fur traders travelled the river. During the second half
of the 19th century, logging became
an important industry in the surrounding Mauricie region. For much of
the 20th century, the river was used
to transport logs to mills downstream
as well as serving as a major source
of hydroelectric power. Today, no
longer serving for log transportation,
the river is travelled mainly by
pleasure boaters wanting to taste the
wild nature of this majestic river.
The Rabaska, named in honour of the
Northern-Western Canadian Artabaska
river and lake system, is a large
canoe for ten paddlers plus a guide. It
was used mainly for the transport and
trading of fur by early settlers with
the First Nations who lived along the
river. Aboard this northern canoe, you
will experience the feeling of the first
explorers discovering the new country, the amazing landscape and the
wildlife that the river has to offer and
a lunch on the river’s sandy shore.

Pointe-du-Buisson was appreciated as
an ideal fishing spot.
For 5 000 years, groups of people
made portages and set up camps at
Pointe-du-Buisson, leaving all sorts

Seaway led to its closing in 1970.
The port of entry for the canal
network linking the Atlantic Ocean to
the heart of the continent, the Lachine
Canal was the forerunner of the transportation revolution in Canada in the
early 19th century. It also played a
decisive role in the industrial development of Montréal, notably as a supplier
of hydraulic power. Finally, this corridor
became one of the main manufacturing production centres in Canada,
from the beginning of industrialization
in the middle of the 19th century until
the Second World War.

Running along the west bank of the
Richelieu River, the Chambly Canal is
nearly 20 km long and links Chambly
with Saint-Jean-sur-Richelieu. Nine
locks allow boats to bypass the
many rapids and negotiate a change
in height of nearly 24 m between
the Chambly basin and the Upper
Richelieu. Opened in 1843, this
canal soon became a powerful
driving force for the economy, allowing
uninterrupted navigation between
Lake Champlain and the Chambly
basin. It was also part of the huge
network of waterways in eastern
Canada and the eastern United States.
All along the route, which is dotted
with many of the original lockmasters’

GREEN CONGRESS
SIL 2007, as an environmentally responsible organization, is striving
to minimize its environmental footprint in the course of organizing this
event, as we are aware that any such gathering has huge environmental
implications. As such, we are undertaking numerous actions to reduce our
usage of resources and maximizing our sustainable actions.
SIL 2007’s policy in regards to having an “Environmentally responsible
Congress” (e.g. zero net carbon emission, zero waste):
“We will address environmental considerations at various stages of our
event planning. We will commit to concrete solutions to reducing the
meeting’s impact on resource consumption and air emissions and we will
make every effort to reach sustainable and responsible decisions when
purchasing services or products for this event.”
The following actions aiming to save energy and money, reduce waste and
protect the environment and human health are being undertaken:
Waste / resource energy reduction and recycling:
• We have selected a congress facility that boasts a BOMA “Go Green”
certification (Le Palais des congrès de Montréal), which rewards good
environmental practices in building management
• We have opted for a “paper free” approach as much as possible for
its communications before the congress – communications between
organizers, participants and committees have been almost entirely
web-based
• Registration and paper submission as well as confirmations were all
done online
bon-positive” and invest the funds received for a further research project
in reducing/sequestering carbon.
Environmental and social responsibility:
• We have enlisted corporate and governmental partners to help finance
and coordinate the carbon offsetting project . See our sponsors below.
• We are actively encouraging congress participants to reduce their own
resource usage during the event through: turning taps off, not printing anything unnecessary, utilizing a reusable mug, walking or using the
public transportation system, recycling their containers and papers, reuse
their towels at hotel, etc.
• Our delegate bags made of recycled material are made locally in a workreinsertion facility, therefore not using low-wage workers and not generating overseas transportation
• Foods used in congress menus will be requested to be locally-sourced as
much as possible and coffee / chocolate to be fair trade.
• Left-over foods will be donated to a local community organization- La
Tablée des chefs
• SIL 2007 is one of the pilot-projects for a standardization initiative
in Quebec to establish a certification for “Management of environmentally-responsible projects”, and its Project Manager sits on the advisory
committee for this initiative. Through this, we have access to a variety of
tools, information on environmental responsibility in congress management, and training.
• We have provided delegate bags that are reusable and made of recycled material
• SIL 2007 has offered a free booth in our exhibition to be shared by local
environmental community organizations that wish to promote their activities
• We have selected hotels for participants that are all walking-distance
from the main congress facility
Communication and education:
• We have been documenting all actions taken in this project
• We have encouraged hotels used for the conference to advertise their
environmental policy
• We have requested that suppliers involved also document their own
initiatives
• We are promoting the use of public transportation in Montreal to
delegates
• We have been promoting our environmentally-responsible initiatives on
the congress website and through various media
• Whenever printing was necessary, we have printed on both sides of
paper or reused single-sided for internal documents
• We will be integrating our initiative in the signage plan onsite
• We have chosen post-consumption paper, double-sided printing and
vegetable-based inks for official congress documents
• We are offering onsite recycling and onsite composting
• We will be advertising the various actions throughout the congress
• We will be assigning volunteers to help support participants in their
waste reduction actions and man a booth promoting the initiative onsite in
the SIL 2007 exhibition
• We will be recycling badges
• A Press Release on SIL 2007 being an environmentally-responsible
congress has been issued a few days before the event and we have integrated our actions in various press communications
• We will be using recyclable containers in all box lunches ordered for
the mid-congress excursions
• We will be working with our congress site to measure the impacts of
“greening” the SIL 2007 congress and will be advertising the results
• We will be using dishes and cutlery that are reusable, avoiding disposable items as much as is possible
Come and visit us at our booth in the exhibition!
• We are offering onsite waste reduction and sorting
• We are distributing to all participants a Nalgene-type bottle in delegate bags
• We will be encouraging participants to use their own reusable bottle
and will not be providing bottled water
• We have been requesting from sponsors and exhibitors that they limit
the distribution of printed literature onsite and encouraged them to use
other means of communication as much as possible
Offsetting carbon emissions:
• We have worked with an environmental consultant in order to evaluate
the global gas emissions generated by the congress
• We have taken action to neutralize the emissions of greenhouse gas by
establishing tree plantations in collaboration with a watershed management organization in rural Quebec. We will be planting over 7500 trees!
• We have registered the SIL 2007 in the UNEP programme Plant for the
Planet: Billion Tree Campaign as well as CSA GHG Registry
• Through our registration process, we have provided opportunities for
delegates to donate a small amount towards making the congress “car-

30th Congress of the International Association of Theoretical and Applied Limnology
SS29: Major Concepts in Physical Limnology
for Biologists and Chemists
Monday, August 13, 12:00 – 18:00
Room 520BE
Tutorials in Physical Limnology
New understandings of lake hydrodynamics have been made possible
by the use of dimensionless indices that predict the nature of mixing
processes in lakes, by laboratory experiments and modeling, by long term
observations, and by the advent of new instrumentation. This session proposes to provide insight into fundamentals, new paradigms, and current
approaches used in physical limnology.
Do lakes mix by wind or convection? What are the implications for
metabolic studies? (Tentative)
Sally MacIntyre and Carolyn Oldham
A general paradigm in limnology is that wind causes mixing in lakes.
However, some lakes are small, some are sheltered, and in some irradiance is rapidly attenuated. In such cases, mixing may be induced by heat
loss rather than wind mixing. This talk will cover the use of dimensionless
indices such as the Wedderburn number for predicting the role of wind in
mixing lakes, will illustrate how surface energy budgets vary over diurnal
time scales in tropical, temperate and arctic lakes and the implications
for mixing dynamics, and will summarize fundamentals in description of
turbulence in lakes.
Dimensionless indices: What is the role of internal wave dynamics
in biogeochemical fluxes?
Sally MacIntyre
Time series of Lake and Wedderburn numbers indicate the likelihood
of formation of internal waves in the thermocline and hypolimnion and
the probability that these will break and induce fluxes of biogenically
important solutes and particles. This talk will cover the interpretation of
these indices based on recent laboratory experiments, modeling and field
observations, and provide a scheme to relate these indices to ecosystem
function.
64
Hotspots of hydrodynamic activity: Implications for fluxes of
nutrients and contaminants (Tentative)
Carolyn Oldham
Near shore regions, the atmosphere, the sediment-water interface, and
river inflows can be major sources of solutes in lakes. Different processes
regulate fluxes at these interfaces and exchange dynamics between
inshore and offshore waters. Methods to quantify fluxes from these processes will be discussed.
Flow in wetlands and macrophyte beds
Andrew Folkard
Vegetation and hydrodynamics have significant effects on each other in a
wide range of different aquatic settings. Vegetation creates flow resistance, attenuates waves and mixing, can shade the water and induce
convective circulation, and reduces the vertical dimension of turbulent
eddies. Vegetation affects the functioning of aquatic ecosystem by trapping particulates, modifying benthic-pelagic coupling, and creating slow
flow zones where rates of biogeochemical cycling differ from non-vegetated sites and depend upon time scales of flushing. This talk will discuss
relevant hydrodynamics as well as techniques for identifying how different
species of macrophytes modify flow.
Acoustic remote sensing of currents, turbulence, particles, and
zooplankton in aquatic environments
Andreas Lorke
The advent of new instrumentation in limnology has opened new doors for
exploration. The use of acoustic Doppler current profilers (ADCPs) allows
measurement of flow speeds including the sub-centimeter per second
flows found associated with internal waves in the hypolimnion of lakes and
time series estimates of turbulence as needed for estimates biogeochemically important fluxes. The backscatter signal from ADCP’s can be used to
determine when and where sediment resuspension has occurred and to
track incoming river water and the patchiness of zooplankton. This talk
will cover fundamentals of the instrument and case studies illustrating the
types of measurements possible.
