Polar bear

Relying on fossil records scientists have found evolutionary path of Polar Bears which is over millennia and shows they are a subspecies of brown bear. About 200,0000 years ago when arctic ocean was completely frozen and covered with glaciers a population of brown bears was wandering in search of food. A part of that population is likely to split off and got isolated because of massive glaciers, most were died because…

caribou, foxes, wolves, lemmings and raptors. Some of the animals, such as the caribou, depend on tundra vegetation to survive the year. Foxes are dependent on the polar bear for the majority of its meals. For example, as soon as a polar bear is done consuming a seal, the arctic fox will devour the remainders left of the seal, since a polar bear is unable to consume an entire seal. Migratory species, such as falcons, also use this habitat. Raptors eat lemmings, voles and hares. Some birds that…

The polar bear is part of the Ursidae family and it’s scientific name is, Ursus Maritimus. It’s physical characteristics are that it is white, six to nine feet and 800 to 1,300 pounds. It feeds upon seals and fish for nutrients. The polar bear population is decreasing drastically because of global warming and is at an all time low of about 22,000. Even though they live most of their lives in the water, their home is on the ice nursing and taking care of their cubs. They were marked as threatened…

true for polar bear populations in the Arctic, as the presence of sea ice is imperative to their survival. Increased alterations in seasonal sea ice retreat and return influence movement patterns, predation, and mating (Derocher & Sahanatien, 2012). Earlier sea ice melt means polar bears must retreat…

The biome that I picked was the Arctic Tundra. The animal from Arctic Tundra I picked is the polar bear. Female polar bears would rather build their den in old snow,( like from a few years ago.) The polar bear is found in Canada , the U.S (Alaska), Greenland, Russia Norway (the Svalbard archipelago), and Arctic Tundra. The Arctic Tundra climate/weather averages to -30°F. In January it is the coldest weather in Arctic Tundra. It’s about -40°F, in January it has reached -93°F before. Most of the…

“Poach the Poachers” Did you know that since 1960, the black rhino population has decreased by 97.6% due to poaching. This is according to the African Wildlife Foundation who is trying to raise efforts to bring attention to the serious danger some animals are in, and the culprit for these animals nearing extinction is in fact humans. For many years the human species has been killing off animals for sometimes no other reason than the thrill they feel when they are hunting down one of these…

stability as humans. The bear perform key roles in its habitat (1) helps in the regulation and control of other species populations. Sickness and mass die offs are consistent with overpopulation. [9] A huge population of Artic seal would have a direct effect on the fishing industry, the result of which will affect how much fish you will consume and the price of that goods. [10] (2) A removal of the polar bear could mean the collapse of other species which depend on the kill of bears for their…

Ever since I was four years old, I have read books watched movies, and have heard out the breathtaking experiences in Alaska. Though I haven't been there, I know everything there is to know about this astonishing state. Polar bears and penguins, are some of the many animals I would dies to study and see up close. Their behavior and adaptations are unlike anything ever seen in this common state we know as home. The climate is like no other, except maybe Antarctica, the snow and ice surrounding…

"Arctic National Wildlife Refuge: A Refuge For America?." Insights To A Changing World Journal 1 (2012): 38-51.Academic Search Complete. Web. 7 Oct. 2015. There are many wildlife species in the arctic regions ranging from, birds, caribou herds, polar bears, and more. The porcupine caribou herds are the main food source for the villages that live the subsistence lifestyle in the Arctic region.The expectations of drilling regarding to wildlife are concerning when it comes to some of the species…
