Abstract Knowledge of when animals feed and the energetic costs of foraging is key to
understanding their foraging ecology and energetic trade-offs. Despite this importance, our …

Detecting when and where animals feed is key to understanding their ecophysiology, but
our ability to collect these data in marine mammals remains limited. Here, we test a tag …

The costs associated with diving are a central component of a sea lion's energy budget.
Accurate estimates of diving costs are needed to assess energetic and physiological …

Three Steller sea lions Eumetopias jubatus were trained to participate in free-swimming,
open-ocean experiments designed to determine if activity can be used to estimate the …

Diving is central to the foraging strategies of many marine mammals and seabirds. Still, the
effect of dive depth on foraging cost remains elusive because energy expenditure is difficult …

Quantification of costs associated with foraging contributes to understanding the energetic
impact that changes in prey availability have on the energy balance of an animal and the …

Foraging behavior is a key ecological factor that has wide-ranging implications for individual
fitness, and population and ecosystem dynamics. There are multiple hierarchical levels at …

Air-breathing divers, such as marine mammals, should adjust their diving behaviours in
relation to the depth and density of their prey to minimize the energetic costs and maximize …

Knowing the quantity of prey that sea lions consume is a prerequisite for assessing the role
of sea lions in aquatic ecosystems and the potential for competition to occur with fisheries …

I investigated diving behavior, movement, and spatially explicit foraging behavior of the
sexually dimorphic male California sea lion and evaluated the extent to which blood and …
