Foraging behavior of adult female and young-of-the-year Steller sea lions in Alaskan waters
- R. Merrick, T. Loughlin
- Environmental Science
- 1 May 1997
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.

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.
High Variability for Control-Region Sequences in a Marine Mammal: Implications for Conservation and Biogeography of Steller Sea Lions (Eumetopias jubatus)
- J. Bickham, J. Patton, T. Loughlin
- Biology, Environmental Science
- 16 February 1996
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.
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.
Diving behavior of immature Steller sea lions (Eumetopias jubatus)
- T. Loughlin, J. Sterling, R. Merrick, J. Sease, A. York
- Environmental Science

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.
Northern sea lion distribution and abundance: 1956-80
- T. Loughlin, D. Rugh, C. Fiscus
- Environmental Science
- 1 July 1984
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 years…
