The key danger for polar bears posed by the effects of climate change is malnutrition or starvation due to habitat loss.Polar bears hunt seals from a platform of sea ice. Rising temperatures cause the sea ice to melt earlier in the year, driving the bears to shore before they have built sufficient fat reserves to survive the period of scarce food in the late summer and early fall.
Polar bear. The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed. The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb). The species is sexually dimorphic, as ...
The ringed seal species is the smallest true seal, and gets its name from a distinctive patterning of light spots on dark grey colored fur. The ringed seal is commonly preyed upon by Polar bears, Arctic foxes, and Killer whales. Population estimates and survival rates are unknown, but average life expectancy is 15-28 years.
An isolated group of polar bears living in southeast Greenland has surprised scientists with its ability to survive in a habitat with relatively little sea ice. Polar bears face existential threat ...
Churchill, Manitoba, is known throughout the world as the place where hundreds of polar bears gather each fall to wait for the sea ice to return to Hudson Bay.The town is also a hub for Polar Bears International and several of PBI's programs including Tundra Connections webcasts [6] – free, live webcasts provided by polar bear and climate scientists and geared towards students, families and ...
But the lack of consistent estimates of population trends and survival rates for some polar bear subpopulations, which are distributed over a very large geographic area with differences in sea ice ...
Arctic National NWR. The Arctic National Wildlife Refuge (ANWR, pronounced as “ ANN-warr ”) or Arctic Refuge is a national wildlife refuge in northeastern Alaska, United States, on traditional Iñupiaq and Gwich'in lands. The refuge is 19,286,722 acres (78,050.59 km 2) of the Alaska North Slope region, with a northern coastline and vast ...
