Why do polar bears have white fur? And nine other polar bear facts Because of ongoing and potential loss of their sea ice habitat resulting from climate change, polar bears were listed as a threatened species in the US under the Endangered Species Act in May 2008. The survival and the protection of the polar bear habitat are urgent issues for WWF.

- Polar bears are in danger of extinction in the future if globalwarming continues, as their habitat, Arctic sea ice, is shrinkingevery year, making it difficult for bears to have enough food tolast through the lengthening summers.With a population of nearly 25,000, the polar bear is not in dangerof extinction now.

- The only predator for the Polar bear is Man (not shown on this ecosystem chart). Polar bears eat the Arctic seal and the Atlantic salmon and has no predator thus for making it the top of its food web. Below is a list of who eats who:

Polar Bears polar bears are considered to be marine mammals. 1  A polar bear's front paws propel them through the water dog-paddle style. The hind feet and legs are held flat and are used as rudders. 2  A thick layer of fat, up to 11 cm (4.3 in.) thick, keeps the polar bear warm while swimming in cold water. Polar bears can obtain a swimming speed of 10 kph (6.2 mph). A polar bear's nostrils close when under water. Diving. Polar bears make shallow dives when stalking prey, navigating ice floes, or searching for kelp.

WWFAbout Us How to HelpSearchSearch wDonate AdoptOur Work Species Places Climate change is altering habitats quickly, forcing animals into increasing conflict with people in the Arctic. In Russia, WWF helped form patrols to monitor and help protect polar bears and walruses. WWF also tracks polar bears by satellite to determine how far and where they travel and how this might be changing.

KidZone Animal Facts The Polar Bear The polar bear or the sea/ice bear are the world's largest land predators. They can be found in the Artic, the U.S. (Alaska), Canada, Russia, Denmark (Greenland), and Norway. Each of these countries either banned hunting or established rules for how many polar bears could be hunted within its own boundaries. These rules help keep polar bear populations stable. Today, 25,000 to 40,000 polar bears roam the Arctic.

Polar bear status, distribution & population A projection of sea ice in the archipelago, supported by WWF, shows that much of the region is facing significant ice loss in the coming decades - with potentially serious consequences for polar bears. Global polar bear numbers are projected to decline by 30% by 2050.

Grizzly bear The grizzly bear is listed as threatened in the contiguous United States and endangered in parts of Canada. In May 2002, the Canadian Species at Risk Act listed the Prairie population (Alberta, Saskatchewan and Manitoba range) of grizzly bears as extirpated in Canada.cientists do not use the name grizzly bear but call it the North American brown bear See brown bear for a discussion of brown bears outside of North America (in Asia, Africa, and Europe).

Study: Polar Bear Populations Have Plummeted 40 Percent in Alaska and Canada Previous studies linked declines in summer sea ice due to warming temperatures to “reduced physical condition, growth, and survival of polar bears,” the report said. Polar bears depend on sea ice to let them travel across the frozen water to hunt for seals—their preferred diet—that emerge through cracks in the ice to breathe. The study found that low survival rates from 2004 through 2006 led to a 25 to 50 percent decline in the number of bears in the region.

- The polar bear is classified as a vulnerable species, with eight of the nineteen polar bear subpopulations in decline. For decades, large scale hunting raised international concern for the future of the species but populations rebounded after controls and quotas began to take effect.or thousands of years, the polar bear has been a key figure in the material, spiritual, and cultural life of Arctic indigenous peoples, and polar bears remain important in their cultures.

Endangered Species Methuselah's Beard lichen is a species living in the boreal forest in Banff National Park. It is endangered because of deforestation and pollution. Lichen is an organism that is made of fungus and usually hangs on the branches of trees. If a tree is cut down, the Methuselah's Beard is no longer able to sustain itself, and dies. Since 400,000 hectares are being cleared in the boreal forest each year, the lichen isn’t growing and spreading as quickly.

Polar Bears In fact baby polar bears can become stranded when blocks drift far apart since cubs cannot swim long distances. Climate information facts indicate global warming is responsible for altering polar bear habitat, the animals they eat, their behavior, life cycle, and life span.

Polar Bear What’s happening now: Although polar bears received Endangered Species Act protection in 2008, the federal government is still failing to stop oil and gas activities in two of the Arctic’s most important polar bear habitats – the Beaufort and Chukchi Seas.

- Effects of Climate Change. Polar bears depend on sea ice as a platform from which to hunt seals, rest and breed. For more than 20 years the summer sea ice has been decreasing in size and melting for longer periods of time.

Global warming may have led to the death of this polar bear, researcher says National Geographic photographer Paul Nicklen captured a photo of an emaciated, deceased polar bear last summer while traveling around Svalbard, Norway, which he posted in recent days. This photograph, along with another photo of an exceptionally skinny polar bear that went viral in late August, would seem to speak to the dangers that global warming poses to the iconic species. Rapid sea ice loss is depriving polar bears of their habitat, since they depend on the ice to hunt prey.

Polar Bear Population Sen. Ted Stevens of Alaska, in objecting to the listing of polar bears as a threatened species under the U.S. Endangered Species Act, is reported to have said: Scientists have observed that there are now three times as many polar bears in the Arctic than there were in the 1970s. What is the basis of this claim? FULL ANSWER

- Polar bears rely heavily on Arctic sea ice, which is rapidly disappearing due to global warming. In Hudson Bay, polar bears are starving during the long summer months as the ice they rely on to hunt for food melts earlier each spring and later in the fall.

- Species: maritimus. General Description: Polar bears are large bears. They have strong legs with large, flattened feet with some webbing between their toes that help with walking on ice and swimming. The wide paws prevent sea ice from breaking by distributing weight while walking.any of the polar bear's physical adaptations help maintain body heat and deal with their icy habitat: 1  The outer layer of fur is hollow and reflects light giving the fur a white color. 2  The white fur helps the bear remain camouflaged in icy and snowy habitat.

Marine Mammal Viewing A powerful and patient predator on land, sea, and ice, the polar bear is the world’s largest carnivore and a unique symbol of the Arctic. Hundreds of thousands of years ago, Ursus maritimus, or the sea bear, evolved from its brown bear (Ursus arctos) ancestors to occupy an ecological niche in the frozen far north.

- Answer: The preferred prey for polar bears are seals-the species they prey upon most often are ringed seals and bearded seals, two species that are members of the group of seals known as ice seals, because of their need for ice for giving birth, nursing, resting and finding prey.olar bears are one of the largest bear species (many sources say they are the largest). They can grow to 8-11 feet in height and about 8 feet in length. Polar bears weigh about 500-1,700 pounds, and they live the cold Arctic-in parts of Alaska, Canada, Denmark/Greenland, Norway and Russia.

Endangered Species The grizzly bear is one of the main endangered species in the boreal forest in Banff National Park. In 2010, the grizzly bear population in Alberta, Canada is estimated to be around 691. This endangerment is primarily because of human hunting. These bears are hunted for their meat and fur.

National Geographic Documentary HD Polar bears and struggle to survive The mitochondrial DNA (mtDNA) of the polar bear diverged from the brown bear, Ursus arctos, roughly 150,000 years ago.[17] Further, some clades of brown bear, as assessed by their mtDNA, are more closely related to polar bears than to other brown bears,[20] meaning that the polar bear is not a biological species.[21] The mtDNA of extinct Irish brown bears is particularly close to polar bears.[22]
