This hibernation-like state does not consist of continuous sleeping; however, the bear's heart rate slows from 46 to 27 beats per minute. The decline of summer sea ice has dramatically changed the face of global commerce and trade in the Arctic and the increase in industrialization and shipping traffic has the potential to significantly impact the Bering Strait and its inhabitants. This also helps them to survive during periods when food is scarce. The polar bears will harass the whales until they tire. They can occasionally drift widely with the sea ice, and there have been anecdotal sightings as far south as Berlevg on the Norwegian mainland and the Kuril Islands in the Sea of Okhotsk. Polar bears are studied to gain understanding of what is happening throughout the Arctic, because at-risk polar bears are often a sign of something wrong with the Arctic marine ecosystem. Polar bears depend on sea ice for their existence and are directly impacted by climate changeserving as an important indicator species. [153], In Russia, polar bear furs were already being commercially traded in the 14th century, though it was of low value compared to Arctic fox or even reindeer fur. Polar bear skin is black and the fur is actually clear, lacking in pigment.

The most accurate counts require flying a helicopter in the Arctic climate to find polar bears, shooting a tranquilizer dart at the bear to sedate it, and then tagging the bear. [48] As the climate change melts sea ice, the U.S. Geological Survey projects that two-thirds of polar bears will disappear by 2050. Ferguson, S. H., Higdon, J. W., & Westdal, K. H. (2012). The Inuit refer to the animal as nanook (transliterated as nanuq in the Inupiat language).

[96][97] They also in places prey heavily upon the harp seal (Pagophilus groenlandicus), the harbour seal (Phoca vitulina), or the hooded seal (Cystophora cristata). Global polar bear numbers are projected to decline by 30% by 2050. [151], Their distinctive appearance and their association with the Arctic have made polar bears popular icons, especially in those areas where they are native. the state that some animals enter during winter in which normal physiological processes are significantly reduced, thus lowering the animal's energy requirements. [183] As of 2015, the International Union for Conservation of Nature (IUCN) reports that the global population of polar bears is 22,000 to 31,000, and the current population trend is unknown. Polar bears are popular in fiction, particularly in books for children or teenagers. [133] Bacterial leptospirosis and Morbillivirus have been recorded. Importing products made from polar bears had been prohibited from 1972 to 1994 under the Marine Mammal Protection Act, and restricted between 1994 and 2008. We support the identification and protection of important polar bear habitat (denning areas and movement corridors, seasonal feeding areas/times, and key resting areas during the ice free period). ", Supplementary material for Ursus maritimus Red List assessment, "Killing polar bears in Iceland "only logical thing to do", "The war over the polar bear: Who's telling the truth about the fate of a Canadian icon? During summer bears may remain on islands or coastlines with landfast ice, drift on ice flows, or get stranded on land where they are forced to endure warm weather.

Adult polar bears can measure over 2.5m long and weigh around 680kg.Their huge size and weight make them the largest living carnivores (meat eaters) on Earth! I enjoy reading and researching new topics. Male polar bears may prey on cubs if they come into contact. Polar bears are the largest of bear species, although brown bears will rival their size in certain regions. [182], Polar bear population sizes and trends are difficult to estimate accurately because they occupy remote home ranges and exist at low population densities. The Canadian two-dollar coin carries an image of a lone polar bear on its reverse side, while a special millennium edition featured three. Although all polar bears have white fur, they vary in color due to varying melanin concentrations in their fur. Male polar bears weigh an average of 770 to 1,500 pounds. 5.
