Habitation of the Polar Bears and their Survival and Reproduction Polar Bears, (Ursus maritimus), an ice-dependant species is known to habitat in sea ice to hunt and feed on seal, to find mates and breed in the ice, for maternity denning and to have access to terrestrial maternity denning areas (Stirling & Derocher, 241). The polar bears use the different parts of the Arctic to survive, breed and habitat. Human impact significantly has a direct and indirect effect on the ecosystem of polar bears. This essay will discuss the habitation of the polar bears, the significance of the Arctic climate to the polar bears and the effect of human activities on their habitation and on their survival and reproduction. Sea ice is critical to the...The end:
