An overview of genetic relationships of Canadian and adjacent populations of belugas ( Delphinapterus leucas ) with emphasis on Baffin Bay and Canadian eastern Arctic populations
Our current knowledge of the molecular genetics of High Arctic beluga (Delphinapterus leucas) populations (West Greenland, Lancaster Sound/Barrow Strait, Grise Fiord) and populations that are related (southeast Baffin, Beaufort Sea), is presented. In general, genetic analyses confirm the designation...
