Fish tissue samples for use in phylogenetic and phylogeographic studies of notothenioid fish

In that time, the notothenioid fish have become the dominant group of fish with about 100 new species appearing in the comparative absence of other competing fish. A wide range of lifestyle, size and unusual physiological adaptations are found in this group.

We investigated the mechanisms and patterns by which all of these notothenioid fish developed, in particular, how significant climate changes are reflected in the pattern of speciation. Individual fish of species common to a number of sites around Antarctica were sampled to look at variation within and between sites and populations (inter and intraspecific variation). Each species caught was identified and photographed (for ID purposes).
