Historical summer distribution of the endangered North Atlantic right whale (Eubalaena glacialis): A hypothesis based on environmental preferences of a congeneric species
Aim: To obtain a plausible hypothesis for the historical distribution of North Atlantic right whales (NARWs) (Eubalaena glacialis) in their summer feeding grounds. Previously widespread in the North Atlantic, after centuries of hunting, these whales survive as a small population off eastern North Am...
