Juvenile Steller sea lion (Eumetopias jubatus) utilization distributions in the Gulf of Alaska [PDF]

Movement Ecology, 2018
Background A utilization distribution quantifies the temporal and spatial probability of space use for individuals or populations. These patterns in movement arise from individuals’ internal state and from their response to the external environment, and ...

Do as I do imitation in a steller sea lion Eumetopias jubatus [PDF]

Animal Cognition
The present study explored whether a well-socialized Steller sea lion named Hama could reproduce similar actions with human demonstrations using the “Do as I do” (DAID) paradigm. Hama had learned 50 types of behaviors, but her social learning ability was

The Genome of the Steller Sea Lion (Eumetopias jubatus). [PDF]

Genes (Basel), 2019
The Steller sea lion is the largest member of the Otariidae family and is found in the coastal waters of the northern Pacific Rim. Here, we present the Steller sea lion genome, determined through DNA sequencing approaches that utilized microfluidic partitioning library construction, as well as nanopore technologies.

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

PLoS 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 ...

Estimating dispersal rates of Steller sea lion (Eumetopias jubatus) mother-pup pairs from a natal rookery using mark-resight data. [PDF]

PLoS ONE, 2017
To monitor population trends of Steller sea lions (Eumetopias jubatus) in Alaska, newborn pups are counted during aerial surveys. These surveys are scheduled to occur after the majority of pups are born, but before pups begin to spend significant time in
