Phylogeography
History, conceptual background and purview of
phylogeography
• 
The term phylogeography was introduced by Avise and co-workers in 1987
• 
Phylogeography is a field of study concerned with the principles and processes governing
the geographic distribution of genealogical lineages, especially those within and among
closely related species
• 
Phylogeography deals with the historical phylogenetic component of the spatial
distribution of lineages
• 
It is an integrative approach that combines diverse micro- and macro-evolutionary
disciplines

Comparative phylogeography of Galapagos fauna
• 
• 
• 
• 
• 
The Galapagos Archipelago occupies a unique position in the history of evolutionary studies.
Oceanic islands are biologically simpler than continental regions.
The time of their geological formation is known.
Each island of the archipelago can be seen as a replicate natural experiment.
Relative limited number of lineages.
Geographical setting and geological history of the
archipelago
13 major islands; 6 smaller islands; 40 islets with official
names and many smaller unnamed islets ~ 1000 km from
Ecuador
• Islands are formed as the Nazca plate moves over an
hot spot (or mantle plume)
• Oldest islands located the southeast of the Archipelago
• Oldest emerged island 3-4 Ma old
• Sunken islands 14 Ma old
• Hot spot 80-90 Ma old
Ecology
• 
Dry climate with marked seasonality.
• 
A warm season (January to May) influenced by warm ocean currents (southward).
• 
A cool season (June to December) influenced by the Humboldt current (from the south to the
west).
• 
Higher islands have higher precipitation.
• 
Every 3-6 years changes in the direction of oceanic currents (El Nino) increase the amount of
rainfall dramatically.
• 
Vegetation on islands can be separated in six altitudinal zones, where plant composition is a
reflection of the humidity level.
Biogeography
• 
Three major track patterns connect the Galapagos with continental areas.

Study cases:
Land snails (genus Bulimulus)
• 
• 
About 80 among species and subspecies have been described for the Archipelago.
Molecular study based on two genes (COI and ITS1) to infer the spatial and temporal
patterns of speciation.
• Progression rule supported
• Sequence of species formation
approximates the pattern of
formation of the islands
• Older islands with monophyletic
and/or less diverse lineages
Parent & Crespi, Evolution 2006, 60: 2311-2328
Study cases:
Lava lizards (genus Microlophus)
• 
• 
At least 17 named and unnamed lineages recognized for the Archipelago.
Multiple mitochondrial genes sequenced (ND1, ND2, COI, tRNAs)

Kizirian et al., Mol. Phylog. Evol. 2004, 32: 761-769.
Study cases:
land and marine iguanas (genera Conolophus and Amblyrhynchus)
• 
• 
• 
Different ecology.
Are these two lineages each other’s closest relatives or not?
12s and 16s genes sequenced; all extant Iguanidae included in the study.
Rassmann, Mol. Phylog. Evol. 1997, 7: 158-172.
Study cases:
Darwin’s finches
• 
• 
• 
• 
• 
Darwin’s finches are one of a few classical examples of adaptive radiations.
Species show adaptive variation in beak size and shape and body size.
Variation at these traits is more typical of differences among families of bird.
Yet the radiation is believed to have occurred in less than three million years.
Three groups based on morphology and behavior: ground-finches (Geospiza); tree-finches
(Cactospiza, Camarhynchus, Platyspiza) and Warbler-finches (Certhidea, Pinaroloxias).
Open questions:
• Are Galapagos finches monophyletic?
• Is the Cocos finch directly related to the Galapagos finches?
• Did Warbler-finch descend from the same ancestor as the rest of
the group?
• Is the vegetarian finch really a member of the tree finch group?
• Is the distinction between ground and tree finches valid?
• MtDNA and microsatellite markers

MtDNA
• Darwin’s finches constitute a monophyletic assemblage.
• Cocos finch are within Darwin’s finch assemblage.
• Warbler-finches are basal in the group’s phylogeny.
• The vegetarian finch is not a member of the tree finch group.
• Ground-finches are clearly a monophyletic group.

Study cases:
Giant Galapagos tortoises
• 
• 
The only extant giant tortoises along with those from Seychelles (but only a single population left).
15 described taxa, of which 11 extant in various stages of imperilment.
Questions:
• Are Galapagos tortoises a monophyletic lineage and where did they come from?
• Patterns and levels of diversification among as well as within islands. Systematics of the group.

Some of the haplotypes found at PBL, PBR, VD and RU differ
from haplotypes from the same location by 27-70 substitutions
while they differ by a few substitutions from haplotypes found in
geographically distant populations (PBL vs. VA/VD/SCR; PBR
vs. ESP; CPA vs PBL). Human induced translocations?

the extant population size) screened at 12
microsatellite loci
• Their genetic profiles compared to the available
database of all extinct and extant Galapogos
tortoise species
•  The genotypes of 84 individuals from V.Wolf result
from hybridization events with a pure
C.elephantopus as one the parents
•  30 of these 84 individuals are less than 15 years
old
•  26 had a C.elephantopus mtDNA
•  There is a good chance that some of these
purebred C.elephantopus are still alive

Outline
•  Introduction to the model organisms (Cyprinids)
•  Current views and hypotheses on the diversification of
cyprinids in Southern Europe
•  Selected study cases: Scardinius (Rudds), Telestes
(Minnows), Rutilus (Roaches), and Alburnus (Bleaks)
•  Evolutionary and biogeographic inferences based on
molecular data
•  Effects of human interferences
Division of freshwater fishes according to
salinity tolerance
•  Primary: taxa that originated and spread in freshwaters strictly intolerant of salt water (Dipnoi, Polypteridae,
Cyprinidae etc.)
•  Primary-like: strictly freshwater species of ancient marine
origins (Gobiidae)
•  Secondary: mostly confined to freshwaters but relatively
salt-tolerant (Cichlidae, Cyprinodontidae, Poeciliidae etc.)
•  Peripheral: recent marine derivates and diadromous taxa
(Lota, Anguilla, Alosa, Salmo etc.)
Cyprinids
• 
The family belongs to the order Cypriniformes
• 
It’s the largest family of primary freshwater fish, with
about 220 genera and more than 2400 species
• 
Despite the diversity of the group little is known about
their relationships

• Diversification of leuciscine lineages has been
determined by intense vicariant events
• Vicariance was largely promoted by the paleoevolution of the Mediterranean region
• B anarescu and Bianco hypotheses are not
mutually exclusive
Take home message:
Banarescu hypothesis (BA) works at the amonggenera level
Bianco hypothesis (BI) targets divergence at the
within-genera level

Padano-Venetian district north of the
Apennines. Four cyprinids and two
cobitids endemics.
Tuscano-Latium district: Central Italy
West of the Apennines. Two cyprinids
and one goby endemics.
Southern Italy district: south of Rivers
Vomano and Tiber. Two cyprinids and
one cobitid endemics.
Arrows indicate the directions of the
freshwater fish transfers.
•  The number of introduced species of European (in grey) and extra
European (in white) origin has been increasing steadily in the last five
centuries
•  All localities host species translocated from Northern Italy (in grey)
•  Eight localities (out of twelve) host species introduced from outside Italy (in black)

Table 2. Illustrative examples of the interactions between non-native, translocated-native (*) and native freshwater fish species in Italy. Origin of native
species: D (Danubian), PV (Padano-Venetian), TL (Tuscano-Latium), AC (Apulo-Campania), ME (Mediterranean), IB (Iberian Peninsula).
Geographical areas are the same as in Fig. 1. Updated IUCN category (Bianco et al. 2013): CR (critically endangered), VU (vulnerable), EN
(endangered), NT (nearly threatened), LC (low concern). It is worth noting that P. genei and R. rubilio are threatened in their native ranges but pest
wherever they have been introduced.

different layers of complexity
•  History of Southern European lineages has been of
preservation rather than dramatic extinction/recolonization events
