The cost of foraging by a marine predator, the Weddell seal Leptonychotes weddellii: pricing by the stroke
Foraging by mammals is a complex suite of behaviors that can entail high energetic costs
associated with supporting basal metabolism, locomotion and the digestion of prey. To …

Linking movement, diving, and habitat to foraging success in a large marine predator
D Austin, WD Bowen, JI McMillan, SJ Iverson - Ecology, 2006 - Wiley Online Library
Establishing where and when predators forage is essential to understanding trophic
interactions, yet foraging behavior remains poorly understood in large marine carnivores …

A phylogenetic analysis of the allometry of diving
LG Halsey, PJ Butler… - The American …, 2006 - journals.uchicago.edu
The oxygen store/usage hypothesis suggests that larger animals are able to dive for longer
and hence deeper because oxygen storage scales isometrically with body mass, whereas …

When does physiology limit the foraging behaviour of freely diving mammals?
Diving animals offer a unique opportunity to study the importance of physiological constraint
and the limitation it can impose on animal's behaviour in nature. This paper examines the …

Individual dietary specialization and dive behaviour in the California sea otter: Using archival time–depth data to detect alternative foraging strategies
The existence of individual prey specializations has been reported for an ever-growing
number of taxa, and has important ramifications for our understanding of predator–prey …
