Genetic population structure of minke whales Balaenoptera acutorostrata from Greenland, the North East Atlantic and the North Sea probably reflects different ecological regions
A genetic study to determine the population structure of minke whales Balaenoptera acutorostrata in Greenland, the Central and NE Atlantic and the North Sea was carried out on a sample of 306 individuals. Samples were analysed by sequencing the D-loop in mtDNA and using 16 polymorphic nuclear micros...
