List of congeneric species of Nothotenids collected in the Falkalnd Islands fo genetic divergence analyses

The dataset contains the locations of congeneric species of Nothotenids collected in the Falkland islands as a part of a project looking at the determination of the levels of genetic divergence among these species from different provinces in the Southern Ocean.

Lineage The individuals collected in the Falklands will be analysed in the lab in Chile. The information contained in their DNA sequences will permit to estimate rhythms and trends in the diversification of genetic lineages of a marine benthic near-shore organism. At the same time, phylogeographic approaches in different species will be used to evaluate the impact of the Quaternary glacial cycles in each of the analyzed SO provinces. Levels of genetic diversity will be conrasted to determine the patterns of genetic structure among these Provinces. It will be possible to determine the effects of the Quaternary glacial cycles over the distribution of genetic lineages in these species and it will be possible to estimate whether the Antarctic species remained in refugia along the Antarctic Peninsula during the last glacial event or re-colonized this area after the LGM from northern Antarctic Islands in the Scotia Arc. Demographic inference analyses will be performed in the analyzed species to determine times and modes of population expansion. Finally, using microsatellites markers, the scale of genetic connectivity in Harpagifer will be evaluated, among populations within species, as a proxy factor of the diversification of the genus along the sub-Antarctic realm.
