Foraging behavior of adult female and young-of-the-year Steller sea lions in Alaskan waters
It is concluded that adult female sea lions can exploit prey throughout the Gulf of Alaska and Bering Sea, and are constrained only by the availability of preferred prey. Expand
Relationship between Fish Size and Otolith Length for 63 Species of Fishes from the Eastern North Pacific Ocean
The relationship between fish length and fish weight, and between otolith length andFish length was linear, and most of the variability was explained by a simple least-squares regression. Expand
High Variability for Control-Region Sequences in a Marine Mammal: Implications for Conservation and Biogeography of Steller Sea Lions (Eumetopias jubatus)
Patterns of macrogeographic variation indicate the presence of two genetically differentiated populations of Steiler sea lions, which likely diverged as a result of separation in different glacial refugia and are paraphyletic with respect to mtDNA. Expand
Separation of foraging habitat among breeding sites of a colonial marine predator, the northern fur seal (Callorhinus ursinus)
It is document that lactating fur seals from the same site share a common foraging area and that females from different breeding sites tend to forage in separate areas and hydrographic domains. Expand
Diving behavior of immature Steller sea lions (Eumetopias jubatus)
Yearling sea lion movement and dive characteristics suggest that immature Steller sea lions are as capable of making the same types of movements as adults as adults. Expand
Oceanographic features related to northern fur seal migratory movements
Northern fur seals breeding on the Pribilof Islands are characterized by pelagic migrations that begin each fall and last approximately eight months. Previous studies have examined the early phasesExpand
Vanadium Accumulation in Pinnipeds
Hepatic vanadium concentrations in liver were significantly correlated with mercury, silver, and selenium concentrations in northern fur seals, Steller sea lions, and harbor seals, although the levels varied with species. Expand
Northern sea lion distribution and abundance: 1956-80
The present distribution and abundance of the northern sea lion (Eumetopias jubatus) was determined from surveys made between 1975 and 1980 and compared to estimates made approximately 20 yearsExpand
