Metal tissue levels in Steller sea lion (Eumetopias jubatus) pups

Marine Pollution Bulletin, 2008
The endangered Western population of the Steller sea lion declined for three decades for uncertain reasons. We present baseline data of metal concentrations in pups as a first step towards investigating the potential threat of developmental exposures to contaminants.

Associations Between The Alaska Steller Sea Lion Decline And Commercial Fisheries

Ecological Applications, 2006
The Steller sea lion (SSL) population in Alaska was listed as threatened under the Endangered Species Act in 1990. At that time, several procedural restrictions were placed on the commercial fisheries of the region in an effort to reduce the potential for human-induced mortality on sea lions. Several years have elapsed since these restrictions were put

STELLER SEA LION BODY CONDITION INDICES

Marine Mammal Science, 2000
AbstractWe 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

Acoustic identification of female Steller sea lions

The Journal of the Acoustical Society of America, 2000
Steller 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.

Hydrodynamic Drag In Steller Sea Lions (Eumetopias Jubatus)

Journal of Experimental Biology, 2000
ABSTRACT 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

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, 2004
The 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 ...

Growth in the Steller Sea Lion

Journal of Mammalogy, 1961
A 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.

Heat increment of feeding in Steller sea lions, Eumetopias jubatus

Comparative Biochemistry and Physiology Part A: Physiology, 1997
The 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
