Environmental Influences on Diel Calling Behavior in Baleen Whales
Our objective is to investigate the relationship between prey behavior and baleen whale calling behavior in a poorly studied environment: the central Gulf of Maine during late fall and early winter. We hypothesize that diel calling patterns are established, in part, by the diel availability of prey:...
