Breeding. © 2021 SeaWorld Parks & Entertainment, Inc. All Rights Reserved. Common Name: Pacific Walrus Scientific Name: Odobenus rosmarus divergens. Like the polar bear, the Pacific walrus depends on sea ice for it’s survival. Such aggregations may be dangerous for calves and juveniles if disturbance by humans or other factors cause adults to stampede. In 2015 a reduced availability of walruses to subsistence hunters led to a food security crisis in the Bering Strait region of Alaska. swimming with its head out of the water. The Atlantic walrus (O.r. RELATED ISSUES Oil and Gas Oceans Climate Law Institute Global Warming and Endangered Species Initiative The Endangered Species Act. If harmful algal blooms increase in frequency and intensity, they could become a major concern not just for walruses but also for the Alaska Natives who depend on them for subsistence. Walruses are adapted to a habitat of sea ice and prefer snow-covered moving pack ice or ice floes to land.

Pacific walrus population size has varied substantially in the last 150 years, it increased between 1960 and 1980 and may have reached the carrying capacity of the marine environment. Yet the body of the walrus is designed to allow them to thrive with these harsh conditions. The 2006 survey did not cover the entire walrus range and therefore is likely to be an underestimate of the total population size. Black dots indicate male walrus summer haulout sites; open circles indicate hunting and monitoring villages. Adverse weather conditions in this region further hinder survey efforts.

The distribution, physical development, pelage, dentition, feeding behavior, reproduction, causes of mortality, and population structure of the Pacific walrus (Odobenus rosmarus divergens) were studied intermittently from 1952 to 1979. Marine traffic and noise associated with seismic surveys could interfere with the walrus migration or cause changes in behavior in the foraging grounds. Some researchers have suggested that the hormones that control sperm development may also inhibit migration in adult males. Some walruses migrate more than 3,000 km (1,863 miles) each year. The Pacific walrus population has been hunted to depletion and allowed to recover several times. The Pacific walrus (Odobenus rosmarus divergens) is one of the main predators feeding on bivalves in Arctic waters. Pacific walrus spend all or the majority of their time in water, and thus are specially adapted to this way of life. Engagement with the region’s Indigenous Peoples will lead to formalized stewardship plans for key wildlife species such as the Pacific walrus and iconic wolverine. The Laptev Sea population was once considered a separate subspecies but recent studies support its recognition as the westernmost population of Pacific walruses.

Identified as a candidate for listing under the Endangered Species Act, but U.S. Environmental conditions in the Chukchi Sea are changing rapidly and may alter the abundance and distribution of marine species and their benthic prey. ... the shift to state-mandated annual hunting targets and plans for catch distribution was not an unbearable intrusion into community life. The reliance of walruses on sea ice for resting during the summer foraging period makes them vulnerable to changes in climate and the associated loss of sea ice. The Pacific walrus population has persisted through past climate change events however, the ability of the Pacific walrus population to adapt to or cope with increasing stress in the future is uncertain. Fish and Wildlife Service (FWS), estimated the walrus population to be about 129,000 but with a large confidence interval of 55,000-550,000 animals. By the early 1980s, walruses appeared leaner.

Their only natural predators include polar bears, killer whales, and humans. Walruses have a disjointed circumpolar distribution. Pacific walrus spend all or the majority of their time in water, and thus are specially adapted to this way of life. Although hunting of walruses for subsistence use could be considered a threat to the walrus population, current harvest levels are thought to be sustainable. Walruses currently are afforded protection in the United States (with the exception of subsistence harvest by Alaska Natives) under the MMPA and they are listed in Appendix III of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Through the winter they generally congregate in three areas, immediately southwest of St. Lawrence Island, south of Nunivak Island, and in the Gulf of Anadyr in Russia. By the 1990s, the population was believed to be stable or in decline, and the current trend is unknown. The Center for Biological Diversity subsequently sued FWS in 2018 for not listing the walrus under the ESA, and the case is still pending. U.S. Walruses are very social animals and congregate in large numbers. In 2008, FWS was petitioned to list the walrus as threatened or endangered under the Endangered Species Act (ESA) and to designate critical habitat for the species. Pacific walrus is summarized, including distribution and migrations by month, general morphology and growth, skin and hair, dentition, food and feeding behavior, reproduction, morbidity and mortality, and … We used a metabarcoding approach to identify potentially important prey taxa from Pacific walrus (Odobenus rosmarus divergens) fecal samples (n = 87). The reliance of walruses on sea ice for resting during the summer foraging period makes them vulnerable to changes in climate and the associated loss of sea ice. Almost the entire population occupies the pack ice in the Bering Sea in the winter months. As the pack ice that they rely on during the summer foraging season in the Chukchi Sea diminishes, walruses are increasingly forced to seek refuge at land-based haul out sites. ... Togiak Refuge has an ongoing marine mammal monitoring program to document their distribution. Male Pacific walrus are slightly larger, with longer tusks. The walrus is the only living species in the family Odobenidae and genus Odobenus. Pacific walruses winter in the central and south Bering Sea and summer in the Chukchi Sea. Elephant Seals, Walruses lying on the beach, California Coastal trail. They also use satellite telemetry to estimate the percentage of the population visible during counts. Consequently, the high spatiotemporal variation in the distribution of resources in the sub-Arctic and Arctic environments likely has favored a gregarious social system in Pacific walrus with high levels of fission–fusion dynamics (Aureli et al. We deployed tags on walruses at locations in the eastern and northern Bering Sea, the eastern Chukchi Sea, and southern coast of the western Chukchi Sea.

Consequently, an alternative approach is necessary to obtain more precise estimates of Pacific walrus abundance and new information on population demographics. This size of congregation, and indeed the Alaskan haul out, is all the more astonishing when you consider the best population estimate for the Pacific walrus subspecies is around 150,000. Pacific walrus distribution varies seasonally and is limited by water depth and ice conditions. Walruses migrate primarily by swimming, but they may also ride ice floes. Walruses live throughout the Pacific and northern Atlantic Oceans on rocky coastlines and ice floes. The walrus in the Svalbard-Franz Josef Land area today belong to a recovering population. Disturbance from a variety of human activities in the Arctic, such as shipping and oil and gas development, can also have negative impacts on walruses. They spend a lot of time in the freezing water. This data release includes two summary geospatial rasters in GeoTIFF format indicating the seasonal Pacific walrus distribution apparent from from ARGOS location tracking obtained from the temporary attachment of ARGOS transmitter tags to Pacific walruses between 1987 and 2015.
