Population identity of North Atlantic humpback whales:An ocean-wide analysis of genetic population structure
North Atlantic (NA) humpback whales (Megaptera novaeangliae) undertake seasonal migrations between high latitude feeding areas (ranging from the US coast to the Barents Sea) and low latitude winter breeding grounds in the Caribbean and the eastern NA (e.g., the Cabo Verde Archipelago). We assessed t...
