Problems in Zoogeography of the Lake Trout, Salvelinus namaycush
Disagreement exists in the literature as to whether lake trout survived Wisconsin glaciation north or south of the ice sheet. Other freshwater fishes whose range in North America equals or exceeds that of lake trout all survived in both northern and southern refugia. Arguments in favour of a souther...
