Arctic Wolf

• Polar bears and brown bears can produce a hybrid offspring • Polar bears evolved from brown bears • The timing of when polar bears first appeared is vital because it determines when they have experienced warm periods with little sea ice historically • Mitochondrial DNA (mtDNA) – relationships based on differences in a group of genes • The polar bear genome discovered alterations in genes related to the development of the heart, cardiovascular function and lipid metabolism – this is why…

The Polar Regions are too cold to support a variety of life. However, scientists have discovered life forms that thrive in this cold environment, and they term the polar oceans as important in maintaining a balance on earth. The amount of water frozen in these regions can be destructive if melted nod released to the warm waters. The McMurdo station is a destination for many scientists to conduct their studies on the waters and the life forms that survive in the cold environment (Nold, 2002).…

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.

Whoever said diamonds were a girl’s best friend never owned a dog! The Siberian Husky is an extraordinary dog breed. In order for this breed of dog to exist there must have been reproduction among other animals to create this breed. The Siberian Husky is said to have been originated from Chukchi, which is a tribe of Siberian nomads (Siberian Husky, 2013). The Chukchi tribe created huskies for their own existence. Chukchi lived in hostile climates in the word were temperatures reached as low as…

Cross breeding plays an important part in the future of endangered animals. In the case of polar bears it may lead more quickly to the extinction of them. Within the past 10 years scientist have found several bears sharing DNA, in this case the two bears sharing the DNA are the polar bears and the grizzly bear. The earth has been heating up which means that the polar bears are getting pushed out of there land space, and are even starting to die off. The polar bears have to expand into the…

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…

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…

Exceptional monitoring efforts have established a shift from Arctic to Subarctic climate regime within the last decade (Grebmeier et al. 2006). Building on the existing 30-year record of direct observations on the water column and benthic macrofauna, I will extend this record back to the last glacial maximum using…

Ender’s Game has several gripping characters that largely contribute to the story. The three Wiggin siblings are like the three bears from Goldilocks and The Three Bears. Peter is like the father bear; his personality is too hard, just like the father bear’s bed. Valentine is like the mother bear; her personality is too soft, just like the mother bear’s bed. Then there was Ender. He is like the baby bear; having everything be just right. However, you couldn’t have a respectable story without any…

creates undersea artic greenhouses” by Thomas Sumner, there is information yet to be discovered before knowing if enough nutrients such as nitrogen and iron are creating these blooms. If more blooms are appearing in the Arctic Ocean, they may already be dramatically reshaping the Arctic ecosystem. With a combination of research and results, both articles demonstrate a shocking summary of how fast our planet has been warming up. For popular articles, journalists or professional authors write for…
