Grolar Bear Research Paper

This is because the females do not have enough food. If they do not have the right amount of protein and energy, they really cannot reproduce. Also, the bear cubs cannot survive in a warmer climate. Their small bodies are not able to handle the warmth when they should be living in the cold. There is not enough breeding going on to keep this species safe and not endangered. The ideal living to keep them reproducing is cold climate, enough food, and endless amounts of ice. Right now, polar bears are losing everything that they need to

It is believed the Polar bears that walk the earth today, had descended from brown bears. This occurred through geographical isolation due to glacial drift in an area close to Siberia. They had undergone a rapid evolution, with changes that enabled them to adapt and survive in an Arctic habitat.

The Polar Bear are found on the icy coasts that surrounds the North Poles and as far south as Hudson Bay. Around 60%of Polar Bears can be found in Canada with the remainings throughout Greenland, Alaska, Svalbard, and Russia where tend to be close to the ocean across the icy fields. The habitats are affected by human encroachment by hunting , and releasing chemical pollutants into the water.The Polar Bear eats Seals, Walrus, and Seabirds. Polar Bears can live up to 20-30 year. Polar Bears have a lot of fur and their fur is clear, white, or yellow. The Polar Bear is 6.5 ft-8.3ft. they can weigh up to 330lbs -1,322lbs and they can swim up to 25mph.

According to Polar Bears International, currently the polar bear population varies from 20 to 25 thousand of individuals.

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.

This week, a viral picture of a sickly polar bear is causing debate all over the world about climate change. Although the issue is not strongly affecting humans just yet, it is influencing wildlife all over the globe. Polar bears, in particular, have been the focus of concern for various organizations that are making it their mission to protect the endangered species. Now more than ever, it seems the polar bear really needs humans to reconsider the choices being made about the environment.

The polar bear is a burly white bear that lives in the lands surrounding the north pole. The polar bears is threatened species because their population is decreasing due to sea ice melting

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).

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.

The average temperature of a polar bear is 37°C, they are able to maintain this temperature by the thick  layer of fur they have, they also have a tough hide and a insulating fat layer. This insulation is able to keep the polar bear warm in temperatures that drop to -37°C. However as polar bears have a very thick layer of fat they can overheat and can die because of this, so the way they are able to keep cool is they do not travel for too long at a slow pace. Doing this stops the polar bear from overheating. If there is excess heat it will be released through the nose, ears, muzzle, footpads, thighs and shoulders as these areas do not have any fur covering it and these areas they have blood vessels which are located close to the skin. Another thing they can do to cool down

The polar bear (Ursus maritimus) is the biggest terrestrial mammal in the Arctic. He is also considered as an animal with a circumpolar or broad distribution in polar regions. The conservation status of bear remains problematic, according to the global warming that is happening now. If further managements are not implanted, polar bear population`s will disappear in the future. The polar bears live in the Arctic, an ocean surrounded by land. The Arctic has a very low species diversity and polar bears the first animal into the food chain. Also, the Arctic has cold winters which are not suitable for some aquatic species. With global warming and interglacial period, the ice and snow began to recede about 20.000 years ago. The rate of ice loss has

Biology Assessment – Evolution of polar bears from brown bears Evolution is defined as a gradual change to the same species overtime to benefit their survival in certain environmental conditions. Jean-Baptise Lamarck and Charles Darwin both had theories regarding evolution and how life on Earth got to be the way it is. Lamarck’s theory of acquired characteristics means he believed that the traits that altered over an individual’s lifetime could be transferred to its offspring. His theory is, that features can be strengthened or rid of completely through use or disuse over generations. For example, if an organism extensively used a certain body part, it would become larger and stronger to adapt to that environment.

Polar bears are one of so many animals that are going extinct . The polar bear is a bear who is a carnivorous whose native range lives in the Arctic Circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. The polar bear is going extinct for many reasons but the main reasons is that there is ongoing and potential loss of their sea ice habitat because of climate change.According to WWF “Polar bears were listed as a threatened species in the US under the Endangered Species act in May 2008. The survival and the protection of the polar bear habitat are urgent issues.”

(2013) found that polar bears have been documented chasing and preying on wild geese, also on eggs of goose, other mammals, and even berries all of these in land. Animals have to adapt to the environment change, polar bears have found a way to find food, but the big questions is, is it enough for polar bears to eat terrestrial food? Polar bears feed on ringed seals because they provide the necessary fat and nutrients that the polar bear needs in other to live. As described by Rode et al. (2015), the consumption of terrestrial food by polar bears has not been sufficient to replace their usual diet. This situation can have a big impact on polar bears, and other species in the environment. Polar bears need ringed seals to survive, but without the seals they have to look for other types of animals. Sritling and Derocher (2012) stated that because of this phenomenon the body mass of polar bears have had a decrease, and also a bigger mortality in polar bears. These can have serious effects on this species because there can be a point in time where polar bears would become extinct. Also encounters of humans with polar bears have become more common because of the necessity of these animals to look for

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.
