Age‐specific reproduction in female Steller sea lions in Southeast Alaska [PDF]

Ecology and Evolution, 2023
Age‐, region‐, and year‐specific estimates of reproduction are needed for monitoring wildlife populations during periods of ecosystem change. Population dynamics of Steller sea lions (Eumetopias jubatus) in Southeast Alaska varied regionally (with high ...

Anatomical features of ossa cordis in the Steller sea lion. [PDF]

J Vet Med Sci, 2022
Irregular triangular cartilage or bone fragments are sometimes found in the fibrous triangle of the heart. Ossa cordis and/or cartilago cordis has been demonstrated in various terrestrial animal species. Regarding marine mammals, sperm whales lack heart bones, and there have been no studies on bones or cartilage in pinniped hearts.

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.

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
