Survival of the fittest serves to be true in all walks of society. When drawing attention to the animals on top of the food chain, it’s important to analyze what sets them apart from the rest. What is the edge they have on the competitors? What are their weaknesses? The animals that occupy the artic regions have learned to survive the furry of Mother Nature, but still must compete for survival with the top predator of the artic, the polar bear.
Polar bears inhabit the circumpolar arctic regions. They live near their primary food source in the ice packs of the artic. The bears inhabit the circumpolar North, which would consist of Canada, Alaska, Greenland, and other regions in the artic. The temperatures range between -40°F to -50°F in the winters and summer temperatures stay around -29°F. When summer reaches the artic the polar bears are forced to travel to the remaining ice. They have adapted to survive in their unforgiving climate, the weather and starvation being their only competitors. They have developed extraordinary capabilities for hunting.
In order to hunt in the artic regions, polar bears have succeeded in adapting to their location. They have developed a large olfactory bulb (Region of the brain that senses smell), which allows them to smell seals almost a kilometer away and a meter under compressed snow. Polar bears weigh 544kg, and could kill almost any animal with a swipe of a paw. Their paws measure up to 31 centimeters across and are purposed to help distribute weight while walking on the ice. Their paws help them maintain stealthy attacks on marine animals, and conquer the obstacle of thin ice. Polar bears are also known as the “Sea Bear”, due to their tremendous swimming abilities. While in the water the...

...ive in the hunt for prey. The artic serves as one of the most extreme climates on Earth. Polar bears have created at series of adaptations such as their coats, paws, and feeding patterns to help combat the subzero temperatures. Reproducing is necessary for a species to survive. Polar bears have learned the most efficient method for raising their young in the artic environment. They serve as the main predator for many of the artic animals, but their only predators carry a different caliber. Global warming and starvation are the only competitors for polar bears in the arctic. Mother nature is an impossible competitor to defeat, but one you must work and adapt to. Polar bears are begging the battle to adapt with mother nature, but will they be able to survive the fight is the question.

Black bears in Alaska range from sea level to the wooded forest. Where they live depends on what time of the year it is. Most black bears are not found on islands in the Gulf of Alaska, but some are found in the southeast near those islands except for Admiralty, Baranof, Chichagof, and Kruzof. They are not on these islands because most are inhabited by brown bears and most bears like to keep to themselves. You hear more about bears that live in the forest then the ones that live by the sea. The habitat of a black bear that lives in the forest is normally wooded areas that has thick vegetation.
Bears can live anywhere but Grizzly bears live in subalpine meadows and dense forests. When grizzly bears hibernate they usually live in caves. A sloth of bears is usually a mom and the cubs. The mom bear is called a sow, the dad bear doesn't have a name because they are never with the family and the babies are called cubs. There is usually a dearth amount of cubs in a family. The families are always together and not with a different family. All bear look different but I'm not talking about the other bears I am talking about grizzly bears. Grizzly bears are usually just the color brown and not really anything different. Grizzlys need big paws to get around and travel. Bears have small black eyes. Their eyes are small because they don't need very good eyesight because they have such good sniffers. Usually the weight of a cub is about 4- 10 pounds when they are born but when they are adults they weigh 175- 500 pounds.
The Arctic region is home to a variety of valuable animals and plants, including polar bear, seal, and so on. The ecosystem of the Arctic region is fragile because these animals are evolved to live in extreme conditions. With the climate change, many animals are endangered. Ice is the habitat of polar animals because they have to rely on sea ices for resting, food, and reproduction. With the climate change and the decrease of sea ice, the number of polar animals is decreasing and their health is threatened. For example, the average weight of female polar bears in 1980 was about 650 pounds, but the number reduced to about 500 pounds in 2004 (Djoghlaf 15). The earlier breakup and later condensation of sea ice shortens the hunting season of polar bears. Polar bears mainly feed on seals that indwell icy land. The melting ice reduces the number of seals and food intake of polar bears. In addition, polar bears are used to living in ice caves. The rising temperature causes the collapse of ice caves, which can kill baby bears. The climate change is negatively affecting the biodiversity in the region and will definitely harm the ecosystem
The characteristics of the grizzly bear as a top predator also make it highly vulnerable to threats. Although it is an omnivore, because it relies heavily on salmon to make it through the winter, it is vulnerable to anything that impacts on salmon runs. It needs wide-ranging habitat and is slow to reproduce. As such, grizzly bears are considered not just a key species but also an ‘umbrella species’ because the protection of their habitats will result in an ‘umbrella of protection’ for a wide range of other species. The protected areas that have been set aside in the Great Bear Rainforest are not enough to sustain healthy populations of grizzly bear so it requires additional habitat set aside from logging. Trophy hunting of grizzly bears also continues to place their population at
The Arctic Tundra is the biome where the Polar bear, Ursus maritimus, or the sea bear live. The climate over there is in the Arctic and is Earth's coldest, where it is treeless and covered with piles of snow and ice for the whole year until summer when it brings wildflowers. On the top of the mountain it is colder, windy, and rainfall is scant.
"The Bull Moose" is a poem by one of the great Canadian poets, Alden Nowlan. It is a finely crafted poem by a very talented poet. It reminds us how far away from Nature the lives of ordinary men and women have strayed. This is something common to all of us who live so much our lives in buildings and who so rarely experience Nature in its raw form. Nowlan creates powerful layers of images, and contrasts them in a way to make us feel just how damaging to our minds and souls this separation from Nature has been. His poem is Romantic in the way it tries to remind us of how far we have fallen and how hollow our idea of progress is. Indeed, Nowlan suggests that we may be more of a beast than the moose.
The habitat of the Arctic wolf is a very harsh place. The temperature must be below zero degrees. There are tundra, rolling hills, glacier valleys, ice fields, shallow lakes, and green flatlands (Arctic/Antarctic: The Arctic Wolf). These snowy white creators don’t have that many places to live. Arctic wolves used to be everywhere in North America, but sadly now they are reduced to Canada, Alaska, Idaho, Michigan, Minnesota, Montana, Wisconsin, and Wyoming (Arctic/Antarctic: The Arctic Wolf). Arctic wolves are one of the most dangerous types of wolves; people need to find a way to save them and their habitat before they disappear forever.
Out of an Ice Age emerged one of our most majestic creatures in the world the polar bear. From its brown bear ancestry, the predator evolved to be a master of a harsh and unwelcoming ice kingdom. Intelligent, adaptable and fierce, the polar bear learned how to survive in a place that offers few comforts to any creature. But now that very environment is in flux. And so is the polar bear’s fate (Nature). Polar Bears are very different from other bears. Polar bears are very large bears compared to Black bears. Polar bears weigh anywhere between 330-1700lbs and Black bears weigh anywhere between 150-600lbs. They have strong legs with large, flattened feet with some webbing between their toes that help with walking on ice and swimming. The wide paws prevent sea ice from breaking by distributing weight while walking. Their paws allow them to pull a 600 pound seal out of its breathing hole (Rosing, 20). The webbed feet results in making polar bears, unlike other bear species to be considered as marine mammals along with seals, sea lions, walruses, whales and dolphins (Polar Bear). According to Rosing Polar bears are excellent swimmers and have been known to swim up to six miles an hour and as far as 60 miles at a stretch. The bears paddle with their front feet and steer with their back feet. They often overheat. Sometimes they venture into the waters just to cool off. When a bear climbs on an ice floe, it shakes itself off because it is trying to prevent ice from forming on its fur (22-23). Because of climate change and hunting of polar bears are now becoming an endangered species which is affecting the food chain. We can fix this by going green, banning polar bear hunting and keep creating these new hybrid bears that are mixed with griz...
In “The Bear” by William Faulkner, there are several different personalities and attitudes that come into play at various times in the story. The story is told from the perspective of Isaac McCaslin, the boy of the story and one of the main characters as well, and many critics feel that this was “probably a projection of Faulkner’s own youthful self”(Monarch Notes 5). Isaac was of the aristocratic class of people who were a part of the South, and who also played a significant part of the stories that Faulkner wrote. Another class of people that were a consistent part of Faulkner’s short stories were the poor-whites such as the Snopes family in “Barn Burning.” Abner Snopes is a man who seems to blame everyone but himself for his problems. Being a Civil War veteren from the Confederate point of view, he was bitter about the War and the way that the Southerners were treated, though it appears that he brought his particular condition upon himself. During the War, the only loyalty was to himself and he remained that way Another class of people that are a significant part of Faulkner short stories are the non-whites which include the Negro, the Indian, and any mixture of the different races found in the South. Abner Snopes gave no regard or respect to the “nigger”(155), who was the de Spain servant and door man, when the Snopeses came to announce their arrival for the sharecropper job, but muttered “get out of my way, nigger.” Sam Waters gained more kindness and respect than that, though he was still a mixed blood in a wealthy, white world. He was

According to the Alaska Department of Fish and Game, the brown bear is located all throughout Alaska, mostly in areas that allow them to seasonally hunt salmon (Alaska Fish & Game, 2010). This allows them to become larger and live in higher concentrations than the grizzly bear. The traditional brown bear and the grizzly bear are actually both classified as brown bears, despite having several differences in appearance. Brown bears are one of the most fascinating and powerful species in the Alaskan wilderness. Cubs are usually born during January or February, usually in groups of one to four (Alaska Fish & Game). A fully grown, male brown bear can weigh up for 1,500 pounds and be over 10 feet in stature (Alaska Fish & Game, 2010). Brown bears also have the ability to run at speeds up to 40 mph for short bursts of time (Alaska Fish & Game). All of these unique characteristics make many people upset that it is legal to hunt them. There are several groups that are working to conserve the brown bear population, particularly in Alaska, such as The Northern Forum’s Brown Bear Working Group (Fish & Wildlife Journal, 2010). The bear population in Alaska is thriving and is classified as a status of least concern, by the IUCN Red List (IUCN, 2010). Overall, the brown bear population faces no danger whatsoever.
To begin with, the melting of polar ice caps has caused polar bears to swim long distances. According to Bryan Walsh of TIME Magazine the melting of the ice caps have caused polar bears especially the young cubs to swim longer distances which has caused a “ forty-five percent mortality rate” (Walsh). In the article Walsh, writes about a study that showed that younger cubs because of low fat and strength were more likely to die due to the long di...
Did you know that animals and plants are dieing from living and even non living things. So predator - prey relationships have a big deal of the population on plants and animals because the predator will eat them. But with the predator - prey relationships they all have a connection together. The one that controls how the population of all the things is the keystone species because they keep everything in check just like a printable in school. But what happens if the keystone species die and can it affect the ecosystem strongly? So living and Nonliving factors have a big affect on the population of the and and the animals.
The polar bear has a long, narrower head and nose, and small ears. The polar bear has coat that appears white but, each individual hair is actually a clear and hollow. This helps the polar bear keep warm. The polar bear's coat helps it blend in with its snowy surroundings, this adaptation helps the Polar Bear hide while hunting. The polar bear's front legs are slightly pigeon-toed, and fur covers the bottoms of its paws. These adaptations help the polar bear keep them from slipping on ice.
