In the Arctic Ice Sheets polar bear roams the wilderness. There may be other bears in the arctic, but the polar bear is the largest land carnivore in the wilderness. The polar bear may look like any other bear, but they are different. Now since the ice caps are melting the polar bear are in great threat of going extinct. The taxonomic group that the polar bear falls under is the Ursidae Group( Tanya Dewey and Phil Myers). Bears inhabit the world all except Australia and Antarctica. Although, they are all in the same group they have different characteristics and different habitats. The Ursidae Group can affect their habitats in good ways and bad ways. The polar bear can hinder the population of breeding seals and elk which is a bad thing, but the brown bear can spread seeds around in their feces(Tanya Dewey and Phil Myers). But, without them other species would overpopulate the world. Each bear in the Ursidae Group is unique, but they all share a lot in common. Bears are strong animals that vary in sizes, but they all have the same strength. They can range from twenty-five to sixty-five kilograms or up to eight hundred kilograms(Tanya Dewey and Phil Myers). In the wild it is most common for the males to be larger than their female counterparts, sometimes you could run across a male that is twice the size of the female. When looking at each bear some characteristics show on each one. Some include small, rounded ears, small eyes, and short tails (Tanya Dewey and
Polar bears are just one kind of animal you can find on the tundra did you know the tundra is the coldest biome of them all? The climate, producers, and consumers, are all parts that make up the tundra.
Polar bears are one of the countless species who are endangered. They were one of the first animals affected by global warming and their population is heavily decreasing. Around 1980, the Arctic was as large as 8 million square kilometres. In 2011, studies show that the Arctic has reduced its size to 4.5 million square kilometers. In the future, will there be anything such as the Arctic? Scientist predict by 2040, only a fringe of ice will remain in Northeast Canada and Northern Greenland. This is known as the Last Ice Area. This matter is mostly taking part in Canada, since; Canada holds more than half the world’s polar bear population. Other affected countries include the U.S. (Alaska), Greenland,
The only predator that a polar bear has is man, before guns polar bears didn’t fear people. In the 1970s polar bears became endangered a law was put up to protect them. To protect them Russia, Canada, Denmark, and Norway are working on ways to stop hunters and to come up with ways to slow down global warming since the glaciers are melting at a rapid pace. Researchers believe there are about 25,000 to 30,000 left in the wild.
The truth is that polar bears are recorded as jeopardized and considered by numerous to be undermined. Explorers can keep away from the governmental issues of Alaska and see these superb animals on a Canadian polar bear visit before they vanish. (Gary 1993, p 117)
There are five major biomes: deserts, grasslands, forests, aquatic, and tundra. The arctic tundra is one which has a frigid climate, whereas a desert is known to be extremely hot most of the year (UCMP. 2016). This is where opportunities are abound for biologists as one who does not appreciate the extreme heat, or has water phobias can study a grassland tundra. What is remarkable is the common species some may have that adapted to the biome. In fact, there are polar bears that live in the tundra and black bears that live in the in the forests. They are both bears; however, a polar bear has adapted to the extreme cold with very thick fur and is white to blend in with the snow. A black bear would not thrive in the arctic tundra as it has adapted to surviving in a forest setting with more moderate
Polar bears live in the Arctic near large portions of ice found in the Arctic Ocean. Due to global warming, these species are forced to remain on coastlines or get stranded on small pieces of
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).
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
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.
Bears are on the top of the food web in the Arctic they are the Tertiary consumers. Polar bears are ferocious
Polar bears are extravagant animals and extremely large. The polar bears native range is within the Arctic Circle surrounding the Arctic Ocean. Since these animals spend most of their life on the sea ice they depend on it, and therefore are classified as marine mammals. Polar bears have many body characteristics adapted for the extremely cold climate they live in and have evolved to full-fill their role in the ecosystem, their main diet is seal and they catch them by standing on the edge of the sea ice.
Polar bears live in the circumpolar north in areas where they can hunt their primary prey ice seals. They are found in Canada (home to roughly 60% of the world's polar bears the U.S. Alaska Greenland Russia and Norway the Svalbard archipelago.
Some polar bears live in different areas but all polar be live in countries that ring the arctic circle and some of the environments that the polar bear can live in include Canada, Russia, The United States, Greenland and Norway. The reason polar bears live in these environments is because all of these environments are cold, snowy and icy. A polar bear has a blubber which keeps the polar bear warm in the cold weather
There may be other bears in the arctic, but the polar bear is the largest land carnivore in the Arctic wilderness. The polar bear may look like any other bear, but they are unique in their own way, such as their characteristics and behavior . The polar bear, has unique characteristics that make it stand out the most compared to the other bears in its taxonomic group.
What will be the fate of the polar bear? The polar bear is an important keystone predator in the Arctic and as such, their presence is crucial for controlling seal populations as well as offering a food source for other animals, like foxes.(Gunderson, 2009) This paper was done to offer some insight on the more current research done regarding the status and biology of polar bears as well as some basic information about them.
