Abundance and Distribution of the Steller Sea Lion
Journal of Mammalogy, 1961Observations of the Steller sea lion, Eumetopias jubata , including hauling-out habits, seasonal movements, and aerial surveys in eastern Bering Sea from Bering Strait to and including the Aleutian Islands, are presented. Sea lions haul out during winter and spring, prior to the breeding season, in greater numbers in afternoon hours than in morning ...

Economic benefit of the protection program for the Steller sea lion
Marine Policy, 2002Abstract This paper examines willingness to pay (WTP) for an endangered species across geographically nested samples using the Contingent Valuation Method (CVM). The three samples range from (1) the boroughs that contain critical habitat for the Steller sea lion to (2) the state that contains these boroughs to and (3) the entire United States ...

Diet of Pacific sleeper shark, a potential Steller sea lion predator, in the north-east Pacific Ocean [PDF]
Journal of Fish Biology, 2006 Pacific sleeper sharks Somniosus pacificus were captured near Steller sea lion Eumetopias jubatus rookeries during the period when Steller sea lion pups are most vulnerable to Pacific sleeper shark predation (first water entrance and weaning).

STELLER SEA LION BODY CONDITION INDICES
Marine Mammal Science, 2000AbstractWe evaluated various measurements of mass, morphology, and blubber thickness as indices of fatness for Steller sea lions by correlation with the percentage of total body mass comprised by the sculp (%SCULP). We concluded LMD‐index was the best index evaluated because it had a relatively high r2 (0.58), had a linear relationship with %SCULP, and

Growth in the Steller Sea Lion
Journal of Mammalogy, 1961A discontinuity (growth line) is formed annually in dentin and cementum of the teeth of Eumetopias jubata . In a sample of 59 individuals, the oldest male showed 19 growth lines, the oldest female 22. Maximum body length and girth were, for males, 325 and 229 cm, for females, 269 and 168 cm.

Acoustic identification of female Steller sea lions
The Journal of the Acoustical Society of America, 2000Steller sea lions (Eumetopias jubatus) breed and rear their young in coastal rookeries dispersed along the northern tier of the North Pacific. Population densities are high and no allomaternal behavior occurs, providing strong selection pressure for mother–pup recognition processes.

Steller watch - time-lapse photography system for remote steller sea lion sites
IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004The ultimate goal of the Steller Watch system is a tool that would provide comprehensive imagery data from remote locations for analyzing Steller Sea Lion behavior and a rich data set for scientific analyses. This project directly addresses three of the thirteen funding priorities for Steller Sea Lions: (1) predation by other mammals; (2) juvenile and ...

Heat increment of feeding in Steller sea lions, Eumetopias jubatus
Comparative Biochemistry and Physiology Part A: Physiology, 1997The heat increment of feeding (HIF) was measured in six captive, juvenile Steller sea lions (Eumetopias jubatus), fed meals of either 2 or 4 kg of herring. HIF was calculated as the post-prandial increase in metabolism above baseline levels, and was measured using open-circuit (gas) respirometry. It averaged 12.4 +/- 0.9% (SE) of ingested energy intake

Hydrodynamic Drag In Steller Sea Lions (Eumetopias Jubatus)
Journal of Experimental Biology, 2000ABSTRACT Drag forces acting on Steller sea lions (Eumetopias jubatus) were investigated from ‘deceleration during glide’ measurements. A total of 66 glides from six juvenile sea lions yielded a mean drag coefficient (referenced to total wetted surface area) of 0.0056 at a mean Reynolds number of 5.5×106. The drag values indicate that the

Food and Feeding Behavior of Steller and California Sea Lions
Journal of Mammalogy, 1966Sea lions taken on land usually have empty stomachs. To obtain sea lions with food in their stomachs, 34 Steiler sea lions and 7 California sea lions were taken at sea. Stomachs of California sea lions contained squids, hake and anchovies. Stomachs of Steiler sea lions taken off California and Oregon contained flatfishes and rockfishes; those taken in ...
