Environmental heterogeneity plays a bigger role than diet quality in driving divergent California sea lion population trends. [PDF]
PLoS ONEWhile the global population of California sea lions (Zalophus californianus) is increasing, regional trends show a decline in the Gulf of California (GoC, Mexico) and an increase in the Channel Islands (CI, U.S.) over the last 40 years.

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

Dokdo sea lion Zalophus japonicus genome reveals its evolutionary trajectory before extinction [PDF]
BMC BiologyBackground The Dokdo sea lion (Zalophus japonicus), commonly referred to as Gangchi in Korea and the Japanese sea lion internationally, was endemic to the Northwest Pacific before its extinction in the 1950s. However, its origins, speciation, and genetic

Population Structure and Genetic Diversity Analyses Reveal Isolation That May Imperil the Northernmost Colony of the Endangered Australian Sea Lion [PDF]
Ecology and EvolutionMarine environments are experiencing rapid warming, substantially altering ecosystems. Populations at the edge of a species' range are more vulnerable to environmental change as they are first affected and may have limited dispersal opportunities.
