The abundance and availability of food are critical determininants of reproductive success
and population dynamics of marine top predators. However, recent work has indicated that …

Understanding the mechanisms that drive prey selection is a major challenge in foraging
ecology. Most studies of foraging strategies have focused on behavioural costs, and have …

Declines of Steller sea lion (Eumetopias jubatus) populations in the Aleutian Islands and
Gulf of Alaska could be a consequence of physical oceanographic changes associated with …

An aspect of life history that has seen increasing attention in recent years is that of strategies
for financing the costs of offspring production. These strategies are often described by a …

Numbers of Steller sea lions Eumetopias jubatus in the North Pacific have declined.
According to the nutritional stress hypothesis, this decline is due to reduced food availability …

Bioenergetics is the study of how animals achieve energetic balance. Energetic balance
results from the energetic expenditure of an individual and the energy they extract from their …

We introduce a modification of the discounted utility model that accounts for both satiation
and habit formation in intertemporal choice. Preferences depend on the satiation level and …

We hypothesized that:(1) Steller sea lion Eumetopias jubatus diet choice is a function of prey
availability,(2) sea lions move to take advantage of times and locations of seasonal prey …

While foraging models of terrestrial mammals are concerned primarily with optimizing
time/energy budgets, models of foraging behaviour in marine mammals have been primarily …

We studied feeding frequency in free-ranging grey seals using stomach temperature
telemetry to test if previously reported sex differences in the diving, movement and diet were …
