Evolution of population structure in a highly social top predator, the killer whale.
Intraspecific resource partitioning and social affiliations both have the potential to structure populations, though it is rarely possible to directly assess the impact of these mechanisms on geneticExpand

Sperm whale population structure in the eastern and central North Pacific inferred by the use of single‐nucleotide polymorphisms, microsatellites and mitochondrial DNA
We use mitochondrial DNA (mtDNA) (400 bp), six microsatellites and 36 single‐nucleotide polymorphisms (SNPs), 20 of which were linked, to investigate population structure of sperm whales (PhyseterExpand

VARIATION OF MITOCHONDRIAL CONTROL REGION SEQUENCES OF STELLER SEA LIONS: THE THREE-STOCK HYPOTHESIS
Abstract Sequence variation in the mitochondrial DNA (mtDNA) control region was analyzed from 1,568 individuals representing nearly every rookery (n = 50) at which Steller sea lions (EumetopiasExpand

Age-specific vibrissae growth rates: A tool for determining the timing of ecologically important events in Steller sea lions
Steller sea lions (SSL; Eumetopias jubatus) grow their vibrissae continually, providing a multiyear record suitable for ecological and physiological studies based on stable isotopes. An accurateExpand

Habitat use and habitat selection by spotted seals (Phoca largha) in the Bering Sea
Twelve spotted seals (Phoca largha) equipped with satellite-linked tags were tracked in the Bering Sea for 46-272 days during August-June 1991-1994. Alaskan seals were mostly near shore duringExpand

Steller sea lion feeding habits in the Russian Far East, 2000-2003
During the breeding seasons of 2000-2003 we collected 1,724 scats from seven rookeries and eighteen haul-outs on the Kamchatka Peninsula and in the Kuril Islands, Okhotsk Sea, and Commander IslandsExpand

Impact of changing diet regimes on Steller sea lion body condition
A leading theory for the cause of the decline of Steller sea lions is nutritional stress, which led to chronic high juvenile mortality and possibly episodic adult mortality. Nutritional stress mayExpand

Age Specific Survival Rates of Steller Sea Lions at Rookeries with Divergent Population Trends in the Russian Far East
After a dramatic population decline, Steller sea lions have begun to recover throughout most of their range. However, Steller sea lions in the Western Aleutians and Commander Islands are continuingExpand
