Another vertebrate that lives in the tundra is the polar bear. Polar bears can be found in northern areas of Canada, Alaska, Russia, and Norway. They are also located in various parts of Greenland. Polar bears are among the largest land mammals on earth. Males can weigh between 700-1400 pounds and stand between 8-10 feet tall. Females only weigh about 350-700 pounds. Polar bears appear to have a white coat, however, their hairs are really translucent and clear. The skin of the polar bear is…

for his chance to catch a walrus or any other food they can find. He tries to jump out of the way of the newly found hole in the ice, but slips. He swerves with all his might to get out of the way of the hole, and barely made it. Now, the ice in the Arctic is melting very fast, due to all the pollution we are causing, and the Inuit are living there, and have to watch as their home begins to melt. In other places, the Iroquois and the Sioux also have to watch the major changes that are being made…

They have white-yellow fur that help them camouflage into the snow and ice in order to help them catch their prey. Polar bears live in the Arctic region. They live on the ice, the coast and islands of the Arctic region. I think climate change and overhunting are most likely to influence the future of the polar bears. I believe climate change is a factor because it causes the loss of ice habitat for the polar bears. This is…

that without the warming of the climate, otherwise would not have become available to mining companies. Since the amount of ice in the Arctic has been decreasing annually, new shipping routes have been accessible, and this helps the shipping industry cut costs. Finally, Inuit communities in the North have been benefiting from the increase in development in the Arctic, as well the cost of food will be decreasing due to the new shipping routes…

Common and Scientific Name Polar bears are commonly known as polar bears here in English but in French they are known as Ours blanc or Ours polaire and in Spanish polar bears are known as Oso polar. Polar bears can also be called sea bear, ice bear or even white bear. Habitat Description and Niche Characteristics Diet: Polar bears are carnivores and their primary prey are seals.

plenty of challenges that put their lives at risk everyday. Furthermore, they took a canoe in the middle of the ocean to catch whales. They also hunted walrus,seals etc… The risk was that the whale could overturn the canoe; not to mention, that in the Arctic, when the tide goes out they create caverns. Which then opens up there is a seafood “buffet” Some seafood that they caught in the caverns was…

Appearance, diet, habitat, natural (or introduced) predators, and reproductive habits Polar Bears live in an arctic marine ecosystem, and its native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. Polar bears have a distinctive white appearance. Their necks are much longer and their head is narrower compared to other species of bears. The front paws are large and used like paddles for swimming. Paws are heavily furred…

Arctic Foxes, also known as Alopex Lagopus, are one of the toughest animals in the world (Alaska Department of Fish and Wildlife). They demonstrate their strength by enduring the Arctic weather, surviving in alpine tundras, on ice floes, and in coastal-style areas (Natural Habitat WWF). The Arctic Fox is recognizable by its long bushy tail, compact body, and varying fur colors from dark gray to white, which change depending on the season. The Pacific Ocean Aquarium. The Arctic Fox is critically…

slowly, but they do this to keep a stable body temperature. Polar bears release extra body heat through their muzzle, ears, and footpads. These adaptations are examples of homeostasis. The only place in the world that Polar bears live is in the Arctic. Their habitats are divided into 19 subpopulations. Polar bears live along the edges of pack ice because water currents and wind work together…

Introduction The arctic environment is being altered by climate change at an alarming rate. Increased worldwide temperatures have caused melting sea ice, which will soon lead to the Arctic being free of ice during the summer months . Greater accessibility of resources like gas and oil, as well as strategic maritime transport advantages, will occur due to this change. The newfound availability of these resources could create competition, which has the potential to lead to conflict amongst the…
