Evaluating gain functions in foraging bouts using vertical excursions in northern elephant seals
The marginal value theorem models patch departure decisions for foraging animals when resources are unevenly distributed. A key component of these models is the decelerating energy...
Searching for prey in a three-dimensional environment: hierarchical movements enhance foraging success in northern elephant seals
1. Foraging theory predicts that predators adjust their movements according to the spatial distribution of prey. Since prey is often patchily distributed, area-restricted search (ARS) behaviour,...
Constrained by consistency? Repeatability of foraging behavior at multiple timescales for a generalist marine predator
Marine predators frequently exhibit consistency in foraging behaviors despite the dynamic nature of marine ecosystems, which has the potential for ecological and evolutionary implications depending on...
Measurements of foraging success in a highly pelagic marine predator, the northern elephant seal
Journal of Animal Ecology
1. Identification of foraging behaviour and the ability to assess foraging success is critical to understanding individual and between-species variation in habitat use and foraging ecology....
