I am trying to find information of how fish populations changed in the central USA/Great Lakes region in the last 100,000 years or so and am drawing blanks
When did walleye/ Sander vitreus appear and where did it come from?. The same goes for brook trout/ Salvelinus fontinalis. Are there any good collections of fossils through the various periods of glaciation?
Are there any regions where these neogene/quatrenary fish fossils are being uncovered?
Where is there a literature on the subject?
