The first range-wide survey of Steller (northern) sea lions (Eumetopias jubatus) was completed in 1989 with a total of 68,094 adult and juvenile (nonpup) Steller sea lions counted. Independent juveniles usually avoid rookeries (Gentry 1970, Sandegren 1970, Calkins and Pitcher 1983, Hoover 1988). The Steller sea lion, Eumetopias jubatus, is the largest otariid pinniped and one of the more aesthetically appealing sea lions.

Steller (or northern) sea lions range along the North Pacific from California to Russia and Japan (Loughlin et al. The two stocks of Steller sea lions (Eumetopias jubatus) in Alaska include an endangered western stock, recently recovering in parts of its range following decades of decline, and an eastern stock which was removed from the U.S. Steller sea lions tend to live in the coastal waters of the subarctic because of the cooler temperate climate of the area. Pups range from 16 to 22.5 kilograms (35 to 50 pounds). Univ. Forage near shore and over the continental shelf (Reeves et al. Its preferred pupping areas include rocky shores and gravel beaches. The Steller sea lion (Eumetopias jubatus) is the largest otariid pinniped species in the world (Loughlin et al. “We want to understand how significant contaminants are in driving changes in Steller Sea lion populations,” said Fadely, a coauthor on the project. Haulout locations include exposed rocks, reefs, beaches, jetties, breakwaters, navigational aids, floating docks, and sea ice. Habitually hauls out on sea ice (Rice 1998). STELLER SEA LION (Eumetopias jubatus): Eastern U.S. Stock STOCK DEFINITION AND GEOGRAPHIC RANGE Steller sea lions range along the North Pacific Rim from northern Japan to California (Loughlin et al. Marks are seen and documented in a variety of ways; remote cameras, dedicated vessel- and land-based surveys, recaptures of Steller sea lions, aerial survey photographs, strandings, and opportunistic sightings sent in from the public. Female sea lions tend to select locations for pupping that are gently sloping and protected from waves (Sandegren 1970). Distribution and Numbers Steller sea lions, also known as Northern sea lions, are the largest of the Otariidae (eared seals) and are distributed around the rim of the North Pacific Ocean from California to northern Japan. 1. Along the eastern and northern Pacific coasts, its breeding range extends from central California, north through British Columbia, Canada, Pp.445-546.

From 1998 to 2011, Steller sea lion pups (<2 months old) were captured by hand or with a hoop net at rookeries (i.e., sites where pups are born, mating occurs, and adult males defend territories) across their Alaskan range during peak pupping season (mid-June to early July; Pitcher et al. Final reports of principal investigators. The Steller sea lion has attracted considerable attention in recent decades, owing to significant and largely unexplained declines in their numbers over an extensive portion of their northern range in Alaska. 1983) but may range out to several hundred kilometers offshore.

Large numbers of individuals disperse widely outside of the breeding season (late May to July), probably to Calkins, D.G. In the 1960s, there were between 250,000 and 300,000 Steller sea lions worldwide. Range and Habitat. Steller sea lion counts in the Gulf of Alaska and the Bering Sea/ Aleutians decreased from the late 1970’s until 2000, then began to increase gradually (Table 1; Allen, 2011). The Steller sea lions’ range overlaps with the California sea lion (Zalophus californianus), but these two species are easily distinguished; the latter is darker and smaller.Definitive distinction from other pinnipeds can be made based on a conspicuous diastema … Range Steller sea lions congregate on rocks in the Gulf Islands of British Columbia, Canada.

Later studies of mitochondrial DNA from Steller sea lions suggest that there are at least two stocks, an eastern stock (California through Southeast Alaska) and a western stock (Prince William Sound and areas west). This dataset contains information regarding the sighting and capture of Steller sea lions marked in Alaska from 1987 to 2014. In 2000, Steller sea lions was estimated to have a global population of about 85,000: a decline of more than 50% since 1960 when an estimated 240–300,000 Steller sea lions lived worldwide.

Temporal and spatial evaluation of the population data show that the 5-year period of rapid decline (1985-1989) was a range-wide phenomenon and hence was most likely caused by an ecosystem-wide change in the Steller sea lion’s environment. In fact, steller sea lions have a fairly small range, especially for a migratory animal.Steller sea lions make their home, both summer and winter, in the waters of northern China to northern California, and go no further north than the article circle.

Bonnell, M.L., M.O. In 1977, this area contained 74 percent of the global population, but by 1989 it dropped to 56 percent. Both subspecies are opportunistic and skilled hunters. Selection of both rookery and haulout sites appears to depend on a number of factors including substrate type, degree of exposure to wind and waves, proximity to food resources, tradition of use, season, and the degree of human disturbance (Gentry 1970, Sandegren 1970, Calkins and Pitcher 1983, Hoover 1988). 1983) but may range out to several hundred kilometers offshore. 1983.

Between the late 1950s and 1970s, overall abundance of Steller Sea Lions in the North Pacific (range-wide: Japan to California) was believed to have been stable at about 250,000-300,000 individuals (Kenyon and Rice 1961; Loughlin et al. and D.W. Rice. Select from premium Steller Sea Lion of the highest quality. Food and feeding behavior of Steller and California sea lions.

In 1990, the Steller sea lion was listed as threatened throughout its range. It was estimated in 2000 that the total range-wide number of Steller sea lions was roughly about 85,000, down from an estimated 240-300,000 in 1960. The beaches can be sand, gravel, cobble, boulder, or bedrock. 1984), with centers of abundance and distribution in the Gulf of Alaska and Aleutian Islands, respectively. 1983). Appearance. The triangles show rookery and haul-out sites (NOAA n.d.). Abundance subsequently declined to about 116,000 by 1989, 97,500 by 1994-95, and 95,000 by 1999-2002. STOCK DEFINITION AND GEOGRAPHIC RANGE Steller sea lions range along the North Pacific Rim from northern Japan to California (Loughlin et al. 1984), with centers of abundance and distribution in the Gulf of Alaska and Aleutian Islands, respectively. For Steller sea lions (Eumetopias jubatus), some hematology and serum chemistry values have been published for wild and rehabilitated pups12 as well as for young, free-ranging Steller sea lions.5,20,24 However, whether these values reflect a normal range is unclear, because the health status of these young wild individuals was un-known. range of flexible input categories that allow students to develop their own experimental questions about Steller sea lion behavior, and to explore a range of parameters, including various specific behaviors, the sex of the animals, and various sampling intervals such as hourly, daily, seasonally, or even annually. While they are most typically found in coastal waters on the continental shelf, they also occur and sometime forage in much deeper continental slope and pelagic waters, especially in the non-breeding season. Sites used during the breeding season (May-August) where pupping occurs are rookeries; haulouts are sites used outside of the breeding season, and by primarily non-breeding adults and other ages throughout the year. The Steller Sea Lion mainly lives in the coastal waters of the North Pacific. Abstract: The first range‐wide survey of Steller (northern) sea lions (Eumetopias jubatus) was completed in 1989 with a total of 68,094 adult and juvenile (nonpup) Steller sea lions counted.This total count includes 10,000 in Russia (15% of the range‐wide count), 47,960 in Alaska (70%), 6,109 in British Columbia (9%), 2,261 in Oregon (3%), and 1,764 in California (3%). The distance sea lions move offshore varies seasonally, with fewer animals being sighted at sea during the summer (Fiscus et al. Even though the range of the sea lion species extends from the cold subarctic to the warm tropical waters of the world’s oceans, there is one ocean where you won’t find any of them. Steller sea lions are distributed throughout most of the North Pacific from the coast of California to eastern Russia and northern Japan.
