Changes in the overwintering diet of Steller sea lions (Eumetopias jubatus) in relation to the 2014 – 2016 northeast Pacific marine heatwave

open access: yesGlobal Ecology and Conservation, 2023
Understanding variation in the diets of endangered species during critical time periods in their annual cycle is of utmost importance because of the effects that diet can have on vital rates and population trends.

No evidence of metabolic depression in Western Alaskan juvenile Steller sea lions (Eumetopias jubatus). [PDF]

open access: yesPLoS ONE, 2014
Steller sea lion (Eumetopias jubatus) populations have undergone precipitous declines through their western Alaskan range over the last four decades with the leading hypothesis to explain this decline centering around changing prey quality, quantity, or ...

Assessment of Competition between Fisheries and Steller Sea Lions in Alaska Based on Estimated Prey Biomass, Fisheries Removals and Predator Foraging Behaviour. [PDF]

open access: yesPLoS ONE, 2015
A leading hypothesis to explain the dramatic decline of Steller sea lions (Eumetopias jubatus) in western Alaska during the latter part of the 20th century is a change in prey availability due to commercial fisheries.

Intraguild predation in sympatric seals and the effect on a declining population. [PDF]

open access: yesJ Anim Ecol
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.

Reduced survival of Steller sea lions in the Gulf of Alaska following marine heatwave

open access: yesFrontiers in Marine Science, 2023
The North Pacific marine heatwave of 2014–2016 (PMH), one of the most geographically-extensive and severe marine heatwaves on record, resulted in widespread and persistent perturbation of the Gulf of Alaska and California Current ecosystems.

Potential Tool Use by Wolves (<i>Canis lupus</i>): Crab Trap Pulling in Haíɫzaqv Nation Territory. [PDF]

open access: yesEcol Evol
Recently, recurring damage to crab traps used by Haíɫzaqv Nation Guardians to control a European Green Crab invasion was investigated with remote cameras. A wolf was recorded emerging from the water carrying a crab trap buoy, then sequentially pulling the attached line up the beach until the initially submerged trap emerged from the water, with the ...

Entanglement of Steller Sea Lions in Marine Debris and Fishing Gear on the Central Oregon Coast from 2005–2009

open access: yesOceans, 2022
Entanglement in marine debris and fishing gear is an increasing problem for the world’s pinnipeds and a contributing factor in Steller sea lion (Eumetopias jubatus) injury and mortality.
