Peter J. Unmack

This web page presents the results of my Master's thesis, the Biogeography of Australian Freshwater Fishes undertaken at Arizona State University as well as ongoing research into the biogeographic patterns of aquatic organisms in Australia and other information pertaining to Australian freshwater fishes.

There are two parts to these pages, some general bits and pieces and the thesis itself.
