[173] In 2010, the Ministry of Natural Resources and Environment published a strategy for polar bear conservation in Russia. These alternatives may reduce the rate of weight loss of bears when on land. Member countries agreed to place restrictions on recreational and commercial hunting, ban hunting from aircraft and icebreakers, and conduct further research.

Pets were as important to the Norse of the Viking Age (c. 790-1100 CE) as they were to any other culture, past or present. Etterspørselen etter kunnskap om isbjørn er stor, og det har lenge vært intens forsknings- og overvåkingsaktivitet blant verdens isbjørnnasjoner. [2][37][38], There are 19 generally recognized, discrete subpopulations, though polar bears are thought to exist only in low densities in the area of the Arctic Basin. [73], Researchers tracked 52 sows in the southern Beaufort Sea off Alaska with GPS system collars; no boars were involved in the study due to males' necks being too thick for the GPS-equipped collars. Biologist Ian Stirling commented, "For many years, the conservation of polar bears was the only subject in the entire Arctic that nations from both sides of the Iron Curtain could agree upon sufficiently to sign an agreement. This kind of social interaction is uncommon; it is far more typical for polar bears to behave aggressively towards dogs. Nevertheless, polar bears are listed as "Vulnerable" under criterion A3c, which indicates an expected population decrease of ≥30% over the next three generations (~34.5 years) due to "decline in area of occupancy, extent of occurrence and/or quality of habitat". [223], This article is about the animal. (Myths and Symbols, 57). Coca-Cola has used images of the polar bear in its advertising,[217] and Polar Beverages, Nelvana, Bundaberg Rum, Klondike bars, and Fox's Glacier Mints all feature polar bears in their logos. Submitted by Joshua J. The population has recovered significantly in recent decades. [5][6] A boar (adult male) weighs around 350–700 kg (770–1,540 lb),[7] while a sow (adult female) is about half that size. The Western Hudson Bay subpopulation is unusual in that its female polar bears sometimes wean their cubs at only one and a half years. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. These features have been selected for in polar bears as a consequence of their almost purely carnivorous way of life. Despite the number of encounters between bears and man likely have increased in recent years concomitant with increased human traffic within the archipelago, the number of bears killed have dropped in recent years. In time, these bears became more of a nuisance than anything else and importing them to Iceland was forbidden by law. [170] Other provisions included year-round protection of cubs and mothers, restrictions on weapons used and various administrative requirements to catalogue kills. [2], According to the World Wildlife Fund, the polar bear is important as an indicator of Arctic ecosystem health. [116], When the ice floes are at their minimum in the fall, ending the possibility of hunting, each pregnant female digs a maternity den consisting of a narrow entrance tunnel leading to one to three chambers. Some regulations of hunting did exist. This license lets others remix, tweak, and build upon this content non-commercially, as long as they credit the author and license their new creations under the identical terms. Sea ice habitat has decreased in periods of the year from 1978 to recent, and in particular, this has affected the number of pregnant females that have been able to reach Hopen and Kongsøya in autumn. The most important denning areas for polar bears in Svalbard are located on Kongsøya, Svenskøya, Edgeøya, Nordaustlandet and Hopen. In Nunavut, some Inuit have reported increases in bear sightings around human settlements in recent years, leading to a belief that populations are increasing. [39] In recent years, polar bears have approached coastal villages in Chukotka more frequently due to the shrinking of the sea ice, endangering humans and raising concerns that illegal hunting would become even more prevalent. Ursus maritimus (Latin). Fra disse tas det prøver for ulike analyser, og flere merkes med satellittsendere som forteller hvordan de vandrer gjennom året. [31] However, the feet are very large to distribute load when walking on snow or thin ice and to provide propulsion when swimming; they may measure 30 cm (12 in) across in an adult. They are markedly sexually dimorphic, with males being larger than females. [115], Courtship and mating take place on the sea ice in April and May, when polar bears congregate in the best seal hunting areas.

Attached to her belt was a large skin purse where she kept the charms she needed for her craft. A large male can mate with several females within the same season, attending each for some days or weeks. Compared to the Antarctic, where there is no major surface predator, Arctic seals use more breathing holes per individual, appear more restless when hauled out on the ice, and rarely defecate on the ice. On her feet she wore calfskin shoes with the hair still on them. Kolenosky G. B. The Egyptians had a strict policy regarding the sale and transport of cats from their country: it was prohibited. The mitochondrial DNA (mtDNA) of the polar bear diverged from the brown bear, Ursus arctos, roughly 150,000 years ago. ", "Determinants of Home Range Size for Polar Bears (, "Polar Bear Ursus maritimus – APPEARANCE/ MORPHOLOGY: TAIL", "Fractures of the radius and ulna secondary to possible vitamin 'D' deficiency in captive polar bears (, "Population genomics reveal recent speciation and rapid evolutionary adaptation in polar bears", 10.1644/1545-1542(2005)86[895:SDOPB]2.0.CO;2. This report may well be dubious, however.
