Polar bear news, and video clips from BBC programmes past and present. In Hudson Bay, James Bay, and some other areas, the ice melts completely each summer (an event often referred to as "ice-floe breakup"), forcing polar bears to go onto land and wait through the months until the next freeze-up. pp. Spring Hill School is a K-12 public school district located in southwest Arkansas. This subpopulation feeds heavily on ringed seals in late spring, when newly weaned and easily hunted seal pups are abundant. [89], With the exception of pregnant females, polar bears are active year-round, although they have a vestigial hibernation induction trigger in their blood. Their scientific name means "maritime bear" and derives from this fact. Government of Nunavut officials announced that the polar bear quota for the Baffin Bay region would be gradually reduced from 105 per year to 65 by the year 2013. [144], The polar bear may swim underwater for up to three minutes to approach seals on shore or on ice floes. After killing the animal, its head and skin were removed and cleaned and brought into the home, and a feast was held in the hunting camp in its honor.

[9] Although most polar bears are born on land, they spend most of their time on the sea ice. Here's what we discovered—and what's next. [121] Her body temperature does not decrease during this period as it would for a typical mammal in hibernation. [161] This decision was approved of by members of the IUCN and TRAFFIC, who determined that such an uplisting was unlikely to confer a conservation benefit. The dental formula is The male's ornamental foreleg hair is thought to attract females, serving a similar function to the lion's mane. [106][107], Although seal predation is the primary and an indispensable way of life for most polar bears, when alternatives are present they are quite flexible.

[36][183][184][185][186][187], The key danger posed by climate change is malnutrition or starvation due to habitat loss. [64] Polar bears gradually moult from May to August,[65] but, unlike other Arctic mammals, they do not shed their coat for a darker shade to provide camouflage in summer conditions. Many features and functions will not be available right now. Polar bears consume a wide variety of other wild foods, including muskox (Ovibos moschatus), reindeer (Rangifer tarandus), birds, eggs, rodents, crabs, other crustaceans, fish[108] and other polar bears. Polar bears can swim 10 km/h (6 mph). ಬದುಕುವ ಹಿಮಕರಡಿಗಳೇ ಮುಂತಾದವುಗಳು ಸಹ ಅಪಾಯದಲ್ಲಿವೆ. [62][152] However, since polar bear fur has always played a marginal commercial role, data on the historical harvest is fragmentary. Their concentrations in polar bear tissues continued to rise for decades after being banned, as these chemicals spread through the food chain. Under those restrictions, permits from the United States Fish and Wildlife Service were required to import sport-hunted polar bear trophies taken in hunting expeditions in Canada. Public Interest Disclosure. [45] As the climate change melts sea ice, the U.S. Geological Survey projects that two-thirds of polar bears will disappear by 2050. [154] The numbers taken grew rapidly in the 1960s, peaking around 1968 with a global total of 1,250 bears that year. [62] Polar bear fur consists of a layer of dense underfur and an outer layer of guard hairs, which appear white to tan but are actually transparent. [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. Polar bears appear to be less affected by infectious diseases and parasites than most terrestrial mammals. This hibernation-like state does not consist of continuous sleeping; however, the bear's heart rate slows from 46 to 27 beats per minute. [36] Disease-causing bacteria and parasites would flourish more readily in a warmer climate. ‎Polar Bear: Snow Run is now on Store. [80], In general, adult polar bears live solitary lives. [84], In 1992, a photographer near Churchill took a now widely circulated set of photographs of a polar bear playing with a Canadian Eskimo Dog (Canis lupus familiaris) a tenth of its size. This report may well be dubious, however. Compared with its closest relative, the brown bear, the polar bear has a more elongated body build and a longer skull and nose. [163], More than 600 bears are killed per year by humans across Canada,[45] a rate calculated by scientists to be unsustainable for some areas, notably Baffin Bay. In their southern range, especially near Hudson Bay and James Bay, Canadian polar bears endure all summer without sea ice to hunt from. [90], The polar bear's most common hunting method is called still-hunting:[91] the bear uses its excellent sense of smell to locate a seal breathing hole, and crouches nearby in silence for a seal to appear. Enjoy the warm fluffy feel of alpaca in this lovable toy. Multiple cases of adoption of wild cubs have been confirmed by genetic testing. [117], Courtship and mating take place on the sea ice in April and May, when polar bears congregate in the best seal hunting areas. [148][149] Polar bear remains have been found at hunting sites dating to 2,500 to 3,000 years ago[151] and 1,500-year-old cave paintings of polar bears have been found in the Chukchi Peninsula. [215][216][217] The Eisbären Berlin hockey team uses a roaring polar bear as their logo, and the Charlotte, North Carolina hockey team the Charlotte Checkers uses a polar bear named Chubby Checker as their mascot.[218].

[23] Polar bears are thought to have diverged from a population of brown bears that became isolated during a period of glaciation in the Pleistocene[4] from the eastern part of Siberia (from Kamchatka and the Kolym Peninsula). These were traded in the villages of the lower Yenisei and Khatanga rivers to the forest-dwelling peoples further south, who would sew them into their hats as protection against brown bears. Research of injury patterns in polar bear forelimbs found injuries to the right forelimb to be more frequent than those to the left, suggesting, perhaps, right-handedness. These areas, known as the "Arctic ring of life", have high biological productivity in comparison to the deep waters of the high Arctic. Chicago (6-7) sacked Watson seven times, including a safety by Khalil Mack, to tie a career high for the Texans quarterback. Bipolar disorder, previously known as manic depression, is a mental disorder characterized by periods of depression and periods of abnormally elevated mood that last from days to weeks each. Thalarctos maritimus, The polar bear (Ursus maritimus) is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. Elsewhere, a slightly larger estimated average weight of 260 kg (570 lb) was claimed for adult females. 475–485 in Wild furbearer management and conservation in North America (M. Novak, J. When kept in captivity in warm, humid conditions, the fur may turn a pale shade of green due to algae growing inside the guard hairs. [100][105] The dump in Churchill, Manitoba was closed in 2006 to protect bears, and waste is now recycled or transported to Thompson, Manitoba. Polar bears are stealth hunters, and the victim is often unaware of the bear's presence until the attack is underway. When walking, the polar bear tends to have a lumbering gait and maintains an average speed of around 5.6 km/h (3.5 mph). Norway passed a series of increasingly strict regulations from 1965 to 1973, and has completely banned hunting since then. The state extends for about 420 miles from north to south and for about 300 miles from east to west. Polar bears rarely live beyond 25 years. At up to 2,000 kg (4,400 lb) and a typical adult mass range of 600 to 1,500 kg (1,300 to 3,300 lb), a walrus can be more than twice the bear's weight,[100] has extremely thick skin and has up to 1-metre (3 ft)-long ivory tusks that can be used as formidable weapons. "[157], Agreements have been made between countries to co-manage their shared polar bear subpopulations. Polar bear. [29] Polar bears can breed with brown bears to produce fertile grizzly–polar bear hybrids;[4][30] rather than indicating that they have only recently diverged, the new evidence suggests more frequent mating has continued over a longer period of time, and thus the two bears remain genetically similar. [103] Maternity dens, used by pregnant females and by females with infants, can also be disturbed by nearby oil exploration and development. The lily is a genus of flowering plant.There are many species of lilies, like trumpet lilies and tiger lilies.
