Research Paper On Polar Bears

and Canada offer, black bears can live in both coniferous and deciduous forests, as well as the open alpine habitats. Basically anywhere near a river or some water source, has plenty of trees, and are able to find food. Black bears usually forage alone, even as young cubs. They will stick together with their mother if there is an abundance of food in one are.

The male American black bear is about 130-550 pounds and the female American black bear is around 90-370 pounds. Black bears are omnivores which means that they eat vegetables and meat. Although black bears are omnivores, they primarily eat vegetation and usually only eat meat after hibernation in the winter. These bears are native to North America and need plenty of land to live and hunt on. Their habitat is usually a large wooded

White bears require a variety of physical characteristics to survive in the harsh environment of the Arctic. Large, wide paws with bumps allow them to distribute weight and grip more efficiently. Water resistant fur with a luminescent quality keep the bear warm and dry. Additionally, Sharp and powerful teeth have the ability to penetrate hard flesh. These special features allow not only the ability to thrive in a difficult environment, but also are important for communicating with other species and another bear.

Their feet are made for the ice and snow; they have rough leather pads so they don’t slip on ice, fur between toes and sharp claws as a weapon. They are plantigrade and left handed. Their toes are webbed so they can swim in water. Their fur is a yellowish white; the top lay is long and hollow to absorb heat and can float in the water. The undercoat covers their black skin that has four inches of blubber, which is an extra layer of warmth. This kind of coat makes it uncomfortable for polar bears to be in the heat. A polar bears sense of smell is the best sense they have, they mostly rely on it. It can smell a dead whale 15 miles away, can smell where a seal is hiding in six inches of ice, and can smell a human before they could even see them. Their eyes are small to block out the sun reflecting off the snow and their ears are small, close to their heads to keep warm.

Polar Bears have dens that tend to be 40 degrees warmer than outside. They has very thick blubber

Wild bears are grand images of nature. Bears live in and utilize an assortment of territory sorts, assuming vital parts in every one. This makes them an "umbrella species," implying that when we secure them and their environment we likewise ensure numerous species. Wild bears can likewise help biological systems by dispersing seeds and supplements through their scat, and every so often controlling ungulate populaces.

The polar bear lives up in the Arctic region where global warming and climate change are melting the ice caps that the bears thrive on. They use the ice as a platform from hunting and rest. The random pocket holes in the ice, where the seals pop up at, is where the polar bear catches its prey. With this reduction of ice, “the abundance of seals, and increases the amount of energy and time needed for hunting, leaving less energy for reproduction” (Endangered Species and Habitats).

The Sun bear is the smallest bear in the bear family. They`re also known as the Malaysian sun bear the honey bear and the dog bear. The sun bear has a unique golden u shape in the middle of its chest. That’s how the sun bear gets its unique name. Male Sun bears can weigh up to 150 pounds and be 5 feet tall.

Polar bears are one of the most endangered species in the IUCN states this is due to Global warming which most of us are still ignorant about, It has a climatic impact on the Arctic by the rising temperature which results in melting the ice glacier and these glaciers are the homes of polar bears that have been disappearing and shrinking making it

 The polar bear has to be able to stay warm in the harsh winter cold. In fact sometimes because they have such thick fur they have to lay down on the snow to cool off so the harsh cold isnt even enough to keep them up to tempreture.

As polar bears inhabit the Arctic regions of five separate nations, it is important to examine the different nation specific management plans in place for conservation of the species. By examining the various management plans in place, a comprehensive look into polar bear management of the species on a global level may be achieved. Of the five nations with polar bear populations, the three largest have some form of a national management plan in place. However, in all five nations, all have specific polar bear hunting regulations and restrictions that also assist in polar bear preservation.

A polar bear is one the most well adapted animals to its environment. They are very advance at hunting for prey like seals. Polar bears have white fur that can be used to be camoflauged when hunting for food, for its children and itself. Polar bears rarely ever seen when ever they are hunting for prey. Although polar bears need to eat a lot of food per day to be able to survive properly. The white fur can also be used to hide from predators. Polar bears could easily avoid predators with their fur and if they're seen they could also flee. Polar bears run can pretty fast on land but if they we're in the water they're a bot slow. Polar bears are great swimmers, it's just that they don't swim very fast. All polar bears need is a male and a female

Polar bears are a unique animal all their own. Male polar bears have a versatile diet and foraging strategy compared to female polar bears, which is proving helpful with recent climate changes. Throughout this paper, the foraging techniques of male and female polar bears will be discussed along with increasing climate temperatures and how it is affecting polar bears.

emigration) in order to adapt to the changing climate. As observed specifically in the Alaskan Beaufort Sea region, there is an increase in polar bears sighted on land, namely in the coast and open water area. Since the polar bears need to be on ice to feed, of which much is thin and lost, the polar bear population has essentially been forced to emigrate to land in order to survive (Kovacs, 2010). Although these polar bears have been able to adapt to the changing climate with changes in their migration, the changes can result in damage. Polar bears are not always able to adapt to their land setting, and need to receive adequate nutrition, which is lacking on land due to the inabilities of acquiring marine mammals, their traditional diet. Along with likely drops of populace, many scientists estimate that polar bears will be forced to make, “long migrations from traditional winter ranges to remnant high- latitude summer sea ice… may ultimately preclude bears from seasonally returning to their traditional ranges (Kovacs, 2010).” There is a chance for polar bears to need to be adaptive to the point of changing their region of migration radically. For polar bears to tread to such locations, there is a chance that there will be a drastic change in an extreme specie and geographical way; both the geographical makeup of the polar bears’ habitat can change along with the specie itself (i.e. survival of the fittest and further adaptations in the possible scope of diet

Polars bears are top predators in the Arctic and are therefore exposed to high levels of pollutants through their food. The popular belief that polar bears live in a pure frozen wilderness is a fantasy.
