North Atlantic minke whale ( Balaenoptera acutorostrata) feeding habits and migrations evaluated by stable isotope analysis of baleen
Abstract Isotopic analyses of the incrementally growing baleen in Mysticeti have been used to learn about their feeding and movement patterns. Using methods previously applied to Pacific minke whales, stable δ 15 N and δ 13 C isotope values were measured along the baleen plates of male and female mi...
