The diverse diet of southern Alaska resident killer whales shifts across spatiotemporally distinct foraging hotspots

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Top predators influence ecological communities in part through the prey they consume. Prey preferences often shift throughout the year, reflecting both seasonal and geographic patterns of habitat use and the relative abundance of preferred prey species.

Intraguild predation in sympatric seals and the effect on a declining population

Journal of Animal Ecology, Volume 94, Issue 12, Page 2572-2583, December 2025.
This study examined the prevalence, spatial extent, and temporal trends of grey seal intraguild predation (IGP). We demonstrated the utility of integrating disparate datasets to address conservation challenges and highlighted how IGP, while seemingly rare, can hold sympatric species in a predator‐pit and in small populations may contribute to declines.

The social behavior of an emerging breeding population of Eumetopias jubatus on the coast of Humboldt County

, 1986
A population of Eumetopias jubatus and Zalophus californianus was studied during the summers of 1983 and 1984 on the coast of Humboldt County. The population of E. jubatus and Z. californianus peaked during June and August. Z.

Wanted dead or alive: characterizing likelihood of juvenile Steller sea lion predation from diving and space use patterns

Endangered Species Research, 2019
Understanding linkages between behaviors and mortality risk is critical for managing populations. Juveniles constitute a particularly vulnerable life stage, with growing evidence that within stages, individual strategies may be associated with greater ...

An Integrative Method for Characterizing Marine Habitat Features Associated With Predation: A Case Study on Juvenile Steller Sea Lions (Eumetopias jubatus)

Frontiers in Marine Science, 2020
Characterizing the habitat associated with predation events can inform on predator-prey dynamics. Despite being evaluated extensively in terrestrial systems, quantifying and characterizing the role predation plays in upper trophic marine ecosystems is ...

A Case Study of Spontaneous Category Formation and Behavioral Expression in a Language-Trained Steller Sea Lion Eumetopias jubatus

International Journal of Comparative Psychology
The purpose of this study was to examine the responses of a Steller sea lion to two consecutive commands. We conducted this study on one same subject, Hama, as a continuation of Sasaki et al.

Winter movements and long-term dispersal of Steller sea lions in the Glacier Bay region of Southeast Alaska

Endangered Species Research, 2018
Steller sea lions Eumetopias jubatus in the Glacier Bay region of northern Southeast Alaska experience greater survival and more rapid population growth than sea lions elsewhere in this region. To better understand demographics of sea lions in the region,
