Article
Lactating Steller sea lions (SSL; Eumetopias jubatus) are income breeders, which balance the energetic cost of provisioning a pup with alternating periods of foraging at sea and nursing onshore during a 12–36 month dependency period. Foraging dives may be benthic or epipelagic, and the diverse diet varies seasonally and geographically. The objectiv...
Article
Cetacean species are highly mobile, most of them regularly travelling over long distances, thereby presenting complex obstacles to their conservation. Identification of their critical habitats, specifically those parts of a cetacean’s range that are essential for day‐to‐day survival and for maintaining a healthy population growth rate, is necessary...
Article
Recent findings that some gray whales that feed off Sakhalin Island (SI), Russia, in the western North Pacific (WNP) overwinter in the eastern North Pacific (ENP) indicate that population structure in this species is more complex than originally thought. We generated mitochondrial DNA (mtDNA) control region sequences and microsatellite genotypes (n...

Mercury (Hg) can be neurotoxic to mammals and impact reproduction, whereas selenium (Se) is an important antioxidant known to ameliorate some adverse effects of Hg. Total Hg concentrations ([THg]) were measured in lanugo (pelage grown in utero) of 812 Steller sea lion (Eumetopias jubatus) pups across Alaska and Russia to assess fetal exposure durin...
Article
Organochlorine (OC) profiles have been used as chemical “fingerprints” to infer an animal's foraging area. North Pacific killer whale (Orcinus orca) populations are exposed to different levels and patterns of OCs based on their prey, distribution, and amount of time spent in a particular area. To characterize concentrations and profiles of OCs foun...

The northern elephant seal does not inhabit the waters of Russia. Encounters with this animal are rare and in most cases occur at rookeries of eared seals. The records of elephant seals from Russian waters in recent decades may be evidence of an increase in their population and expansion of the species range. This report provides summarized data on...
Article
Accurate age determination of individuals is crucial in estimating age structure in populations as well as age‐specific rates of reproduction and survival. We examined growth layer groups (GLGs) in the canine, incisor, and postcanine teeth of Steller sea lions (Eumetopias jubatus) to find the optimal method to determine their age using 18 known‐age...
