Population structure of long‐finned pilot whales in the North Atlantic: a correlation with sea surface temperature?
Abstract The long‐finned pilot whale, Globicephala melas , is a social, pelagic odontocete distributed widely in the cold temperate waters of the North Atlantic. Despite genetic, morphometric, physiological and observational studies, it remains unclear whether any population substructure exists. We...
