Ecological contexts of diving behavior in Hawaiian false killer whales Movement Ecology

Predator movements vary across different ecological contexts, offering valuable insights into their foraging strategies. However, studying these contexts in marine predators is challenging due to the difficulty of observing them and their prey over sufficient spatiotemporal scales. Using bio-loggers and detailed life history information, we investigated abiotic and biotic factors shaping the diving behavior of a highly social apex predator—the false killer whale (Pseudorca crassidens)—around the Hawaiian Archipelago where three partially sympatric, genetically differentiated populations coexist.
