Individual and population dietary specialization decline in fin whales during a period of ecosystem shift
This study sought to estimate the effect of an anthropogenic and climate-driven change in prey availability on the degree of individual and population specialization of a large marine predator, the fin whale (Balaenoptera physalus) in the estuary and the gulf of St. Lawrence (eastern Canada).
