Divergent foraging strategies between populations of sympatric matrilineal killer whales ...
In gregarious species, collective behavior maximizes individual fitness benefits while minimizing costs. Despite the relevance of behavior to conservation, the link between the robustness of behavioral patterns across populations and population health is poorly understood. We studied the collective...
