Population history and phylogeographic structuring
in different latitudes of Northeast Atlantic Estuarine Fishes
With the prospect of global warming, it is predicted that
boreal and artic marine and estuarine species will suffer
an increasing shift of their southern distribution to the
north, while the populations of termophilic species are expected
to move northward. This project aims to clarify the phylogeographic
structure of several estuarine fishes, especially in the northern
and southern limits of their distribution. For this, standard
phylogeographic and historical demographic tools, like haplotype
networks, estimates of population parameters through the coalescent
approach and analysis of molecular variance will be applied
to sets of mitochondrial and nuclear markers in samples collected
in the south (Portugal), middle (Netherlands) and North (Norway)
of the studied species distribution. These include the European
Flounder, Platichthys flesus (Linnaeus, 1758), the plaice,
Pleuronectes platessa Linnaeaus,1758 , sea and river lampreys
Petromyzon marinus Linnaeus, 1758 Lampetra spp. Bonnaterre,
1788, sand goby, Pomatochistus minutus (Pallas, 1770) and
trout Salmo trutta Linnaeus, 1758.
