GROWTH IN BODY SIZE OF THE STELLER SEA LION (EUMETOPIAS JUBATUS) [PDF]

Journal of Mammalogy, 2001
Growth models (mass and length) were constructed for male ($1 year old), female ($1 year old), and pregnant female Steller sea lions (Eumetopias jubatus) shot on rookeries or haulouts, or in coastal waters of southeastern Alaska, the Gulf of Alaska, or the Bering Sea ice edge between 1976 and 1989.

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

Global 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.

Adnocarcinoma of the Lung in a Steller Sea Lion (Eumetopiae jubatus).

Journal of Veterinary Medical Science, 1998
The histological and ultrastructural characteristics of an adenocarcinoma of the lung are described in an about 16-year-old female Steller sea lion with a 1.5 month history of cough and anorexia. The animal had multiple neoplastic nodules in the lungs and diaphragmatic pleura. The bronchial and mediastinal lymph nodes were replaced by neoplastic tissue,

Aging steller sea lions by growth layer groups in teeth

Wildlife Society Bulletin, 2019
Accurate age determination of individuals is crucial in estimating age structure in populations as well as age‐specific rates of reproduction and survival. We examined growth layer groups (GLGs) in the canine, incisor, and postcanine teeth of Steller sea

Capelin Size, Condition, and Abundance Through Multiple Heatwaves in Alaska

Fisheries Oceanography, Volume 35, Issue 3, Page 413-429, May 2026.
ABSTRACT Capelin (Mallotus spp.) are pelagic forage fishes that can be especially abundant in sub‐arctic marine ecosystems and are important prey for upper trophic‐level consumers. Abundance and distribution of capelin have been linked to ocean temperature, but the magnitude and directionality of thermal sensitivity can vary regionally.

Annotation and comparative analysis of T cell receptor germline genes reveal lineage-specific patterns in pinnipeds

Frontiers in Immunology
Adaptive immunity in jawed vertebrates relies on V(D)J recombination, yet the expansion–contraction dynamics of germline genes remain underexplored, especially in secondary aquatic mammals.

Activity as a proxy to estimate metabolic rate and to partition the metabolic cost of diving vs. breathing in pre- and post-fasted Steller sea lions

Aquatic Biology, 2013
Three Steller sea lions Eumetopias jubatus, trained to dive voluntarily to depths ranging from 10 to 50 m, were used to determine whether the relationship between activity and metabolic rate during a diving interval (MRDI, dive + surface interval) was ...
