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

Lions & sea lions & bears, oh my: utilizing museum specimens to study the ossification sequence of carnivoran taxa [PDF]
Background Mammalian skeletons are largely formed before birth. Heterochronic changes in skeletal formation can be investigated by comparing the order of ossification for different elements of the skeleton.

Pathobiology of Highly Pathogenic Avian Influenza A (H5N1 Clade 2.3.4.4b) Virus from Pinnipeds on Tyuleniy Island in the Sea of Okhotsk, Russia [PDF]
Highly pathogenic avian influenza (HPAI) A(H5N1) clade 2.3.4.4b has recently emerged as a major threat to wildlife, agriculture, and public health due to its expanding host range and the increasing frequency of spillover into mammals. In July–August 2023,

Diving behavior of immature Steller sea lions (Eumetopias jubatus) [PDF]
Understanding the ontogenetic relationship between juvenile Steller sea lions (Eumetopias jubatus) and their foraging habitat is key to understanding their relationship to available prey and ultimately their survival. We summarize dive and movement data from 13 young-of-the-year (YOY) and 12 yearling Steller sea lions equipped with satellite dive ...

Stranding trends of Steller sea lions Eumetopias jubatus 1990-2015
Distinct population segments of Steller sea lion (SSL) Eumetopias jubatus have experienced different population trends over the last 5 decades, rendering the need for retrospective study. By identifying long-term stranding trends of SSLs we can develop a

Rare Record of Albinism in a New Zealand Fur Seal (<i>Arctocephalus forsteri</i>) Pup With Observations Through the Weaning Period. [PDF]
This article provides the first known scientific record of albinism in a New Zealand fur seal pup. We describe the individual with a particular focus on its sensory abilities. This individual's birth at a central mainland colony may permit continued study throughout his life, unlike many records of similar conditions in other species.

Steller Sea Lion (Eumetopias jubatus) Response to Non-lethal Hazing at Bonneville Dam
Protected Steller sea lions (Eumetopias jubatus) aggregate at Bonneville Dam on the Columbia River and prey upon multiple species of endangered salmon ascending the river. Hazing is a non-lethal activity designed to repel sea lions that includes aversive
