Research Paper On Polar Bears

The melting sea ice is also affecting the polar bear's main prey, seals, forcing the bears to turn to alternate, less nutritious food sources. Once sea ice forms in the winter, seals use the ice to create dens to give birth to their pups. In these months, polar bears use sea ice as their hunting grounds to find seal dens. Now that Seasonal Ice is forming later and melting earlier (IPCC, 2013), seals have less time to build dens and give birth. Consequently, polar bears have less time to hunt their preferred prey of seal pups. They must spend more time on land hunting other animals of less nutritional value. Organizations like Sea World Parks have reported male polar bears occasionally eating newly-born polar bear cubs because they cannot find other food to eat. Lack of nutritional food leads to a reduced body size. Polar bears are becoming thinner and weaker from not eating enough (Rode, Amstrup, & Regehr 2010). They have to swim longer distances to find ice to hunt upon, causing many cubs to die because they are not yet strong enough. In the Hudson Bay, the average polar bear weight has decreased by 15% and the population has decreased by 20% (National Wildlife Federation). In the summer when there is no ice, polar bears in the Hudson Bay go onto land to fast until the ice reforms. Now that ice is

Spirit bears people call them spirit bears although there real name is Kermode bear the Kermode bears lives Outside of Columbia only however one in a million black bears is white the rest are black only maybe 100 exist spirit bears are really interesting . Only about 20 percent of the bears on Orr and Princess islands are white the rest are black they have white creamy fur with brown eyes dark nose pads and nearly white claws .

Black bears are the smallest North American bears however; they are the largest land mammal in New Jersey. Black bears evolved in thick forest and live in mixed hardwood forests, dense swamps and forested wetlands. They naturally like to eat fresh leaves, berries, fruits, nuts, roots, insects, bird eggs and small mammals. Black bears are generally solitary animals, with the exception of a sow and her cubs. They tend to be crepuscular, meaning they are most active shortly before sunrise and again after sunset. Black bears are typically not aggressive and tend to be wary of humans.

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 black bear is one of the most common bears in the U.S.A. Even though the black bear is one of the three smallest bears, it has great claws and amazing climbing ability. Experts estimate that about 80,000 black bears die each year in the U.S.A. This animal, the black bear, is threatened and should be saved.

As a result, humans are slowly destroying the bear's ability to reproduce, and function in a normal way. By removing chemicals such as mercury, DDT, PCBs and lindane to name a few from our waste it is possible that the world may be able to retain our population of arctic polar bears, and preserve the beautiful creature for generations to come. Alternatively, people should use this as a warning of things to come if they continue to be so irresponsible about their waste. The implications to other ecosystems could be sufficiently more devastating than what is being witnessed in the arctic, and it is humanity's responsibility to take action now before it is too

With the ever rising global temperatures, melting ice caps, and constant warnings about global warming, it is no wonder that the animals inhabiting the artic regions around the world are now suffering a decline in their habitat as well as their livelihood. Such is the case with the Polar Bears who may soon be gone in a scant few years.

Polar bears diets mainly rely on seals so the current changes in ice will affect the life cycle of the seals as well as it will play a big role in the life cycle of an adult polar bear. A large decrease in adult polar bears has been noticed and is believed to have been noticed and is believed to have been caused by the ice changes over the last few years as the decline in the seal population results in the polar bears being hungry during the winter which means they are not storing enough fat to produce energy to keep them alive all winter resulting in the polar bears unable to survive the cold winter months without their natural food source (Prowse et al,

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.

The polar bear, the largest land carnivore in North America, one of the largest animals in the world and a favorite at zoos worldwide, has, over the years, adapted to its harsh Arctic environment. The appropriately named ‘ursus maritimum’ or sea bear usually lives between 15 and 18 years in the wild and spends most of its life on ice. It is the most recent of the eight bear species. The first polar bear was a brown bear subspecies, with brown bear dimensions and brown bear teeth. The polar bear evolution was rapid due to the small population and extreme pressure to survive. Even today, the polar bear continues to evolve to better adapt to the harsh realities of Arctic life.

Scientists say that the melting of Arctic ice and ice caps are harmful to essential life of arctic animals like polar bears because they live on Arctic ice and ice caps (Rinkesh). Research has proven both of these theories wrong. The Arctic ice and ice caps have increased and are still increasing. Since 2012, the Arctic ice and ice caps have increased in volume by fifty percent (Foley). There are over twenty thousand polar bears in the world and over sixty percent of these polar bears live in Canada (Matishov). The population of polar bears is increasing and staying at a stable rate, depending on their location (Global Warming and Polar Bears). Since, both of these theories have been proven wrong, we do not believe that “global warming” is affecting the Arctic ice or Arctic

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).

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

Polar Bears have become one of the most well-known and protected species over the course of the last ten years, but still so few people understand how amazing these creatures truly are. The scientific name for the polar bear is Ursus Martimus. Though Polar Bears are part of the bear family they do have some differences. Polar bears can only be found in the Artic, the northernmost part of the Earth.

Another risk factor is climate change, changing temperatures and changing their habitat, polar bears are being forced on to landmasses and entering into communities to obtain food for their survival. The polar bears are being seen more prominently in communities usually trying to find food, because of the drastic changes in their habitat.
