Genetic diversity and population structure among northern bottlenose whales, Hyperoodon ampullatus , in the western North Atlantic Ocean.
To assess population structure and genetic diversity among northern bottlenose whales (Hyperoodon ampullatus), we compared mitochondrial DNA control region sequences from three populations in the western North Atlantic Ocean. Skin-biopsy samples were collected from animals in the Gully off Nova Scot...
