...SPECIES- Ursus Maritimus, Polar Bear, lord of the Arctic. Lives in an area of five million square miles of snow and ice. From Siberia to Alaska and across Canada, Greenland and the Islands north of Norway, he is the master of all living things except man. It lives in the brutal cold, ice, and snow. The temperature can plunge down frequently to -40 degrees and sometimes even lower but that does not bother the polar bear because of its color-less skin and layer of insulation fat. Its range extending around the northern polar region. Necessities of Life-The polar bear eats mostly seals which he has to hunt. His trick is to wait by a breathing in the ice and when a seal comes up by that breathing hole, he grabs it so fast it knocks it unconscious and then he eats it. Other pray is a walrus calf or a musk ox stuck in snow, birds, eggs, fish, and dead whales. And sometimes in the summer it eats berries and grass. The polar bear has no water to drink so it only eats the skin and blubber, avoiding the meat. So by eating the blubber and leaving the meat the male bear is helping keep his body in balance with the surrounding environment. The bear would usually stay in a den or bury it self in the snow to avoid the suns ultra violent rays. Usually the pregnant female polar bear stays in the den.Food Chain-The polar bear finds its way on the top of its food chain. No predator on earth approaches the bear in size. The polar bear towers over everything else in his food chain. The...

... - Also helps to keep bear from slipping on the slippery ice - Hair usually shakes free any water or ice formed after swimming 2. Hollow fur - Traps air inside, thus making the bear buoyant in water - The layer of air provides insulation between their warm bodies and the cold Arctic air and water - Insulation provided is lost when fur is covered with oil 3. Small and rounded ears - Prevents water from entering the bear's ears and freezing their eardrums, u see, big ears, more water! - Helps conserve body warmth in sub-zero temperatures 4. Digging of dens several metres deep - Shelter from winds that sweep over the ice in strong gusts, unbroken by trees or vegetation 5. Light colour of bear's fur provides camouflage against the ice - When hunting, bear covers black nose with its paws to hide it 6. Strong swimmers - Polar bears can travel up to a speed of 10 kph - Have been known to swim continuously for 100 km - Enables them to catch prey 7. Thick layer of fat (blubber) under skin - Up to 11 cm thick - Insulates bear from arctic cold - Overheating might occur - To prevent overheating, the bear moves slowly, resting often - Excess heat is released from the body through areas where fur is absent or where blood vessels are close to the skin (eg. muzzle,...

...It is well known that the Arctic and Antarctic regions have harsh, cold winds, low temperatures and heavy snow fall, however, these environments are home to many species of birds and mammals which successfully survive and reproduce in spite of these extreme, seemingly uninhabitable conditions. They need special adaptations to help them survive and have many difficult obstacles to overcome including regulating and maintaining body temperature, coping with predation and with scarcity in food. The arctic fox (Vulpes lagopus) is native to the Arctic regions of the Northern Hemisphere and inhabits the arctic tundra environments of Eurasia, North America and the alpine tundra of Fennoscandia. Within the worldwide population there are several hundred thousand individuals (The IUCN Red List of Threatened Species, 2013). Populations vary in response to numbers in small mammals. They hunt lemmings, which are their main prey (Strand et. al., 1997), small birds and their eggs and also scavenge carcases in times where food is scarce (Hiruki and Stirling, 1989). Arctic foxes are relatively small mammals at around 3-8 kg. They have small ears, short noses, fur covering the pads on its feet. Its brush like tail aids in keeping its balance but is mostly used for insulation. During the winter arctic foxes have a thick white fur which provides camouflage against the white snowy expanse of the tundra and protection against the harsh environments, in the summer its coat becomes thinner and changes...

...How does the writer show the conflict in her thoughts and feeling about hunting? The writer uses her personal experience to describe the feeling and thoughts in a harsh environment vividly. In the third paragraph, the writer writes a few sentences to show that ‘an essential contributor to the survival of the hunters in High Arctic’. It can be obviously seen that catching the narwhals to eat is necessary, as the people need to survive on them. The author uses some technical language such as ‘vitaminC’ and ‘scurvy’ to implie that this is the only source of food, energy, tools and money in the High Arctic, which shows her sympathy to the hunters as hunting for Narwale is the only job they can do. The area in the High Arctic is not suitable for growing other vegetables. Narwhals has a rich source of useful nutrition, so Inuit people catch the narwhal as a main source of food. Also, the Narwhal’s ivory can be used for many things such as ‘harpoon tips’, ‘hunting implements’ and ‘central beam for their small ancient dwellings’. These fully describe that Inuit people can’t live without the Narwale, as it can help the Inuit people to survive. The writer’ feelings are explicit in the sixth paragraph, the hyperbole, such as ‘my heart leapt’ is used when the hunter was about to harpoon the narwhal. It shows how narwhal’s intriguing action is. The hunter has much courage to catpure the Narwale, which it is not a easy job at all and should...

...Coke’s Polar Bears Coca Cola’s polar bear has been around for quite a long time, being introduced in a paper ad in France, 1922. The polar bear is a well-known symbol for Coke even though they portray the animal much different than it lives in the wild. It’s a symbol because an animated polar bear wouldn’t mean much to someone outside of our culture, but Coke has ingrained in our culture that it aligns with them. We created our infographic to display the benefits that both Coca Cola and the polar bears receive. Coke has done some great things for the polar bears but much more can be done. The polar bears have receive almost $2 million in support from the World Wildlife Fund (WWF). There has been a substantial reduction in deaths of polar bears from trying to uphold a section in the high Artic that the ice will last the longest. Certain surrounding tribes have also slowed down or even completely stopped killing polar bears. Coke has also alerted the public and since they are becoming aware they want to help. I added the picture of the three cubs laying on top of their mother to allude that the polar bears are happy and in stable conditions. Coke has garnered much public appeal since starting the campaign. They teamed up with WWF in 2011 and since then they have accomplished in reducing carbon emissions by 8.5%. The benefits they receive are substantial. The more people they bring onto the product, in turn their profits will increase profoundly. Even though coke has provided...

...Scientists have studied the feeding habits of the extinct Cave Bear. Based on the isotope composition in the collagen of the bears' bones, they were able to show that the large mammals subsisted on a purely vegan diet. The team proposes that it was this inflexible diet that led to the Cave Bear's extinction approximately 25,000 years ago. In the study, recently published in the scientific publication Journal of Quaternary Science, the international team proposes that it was this inflexible diet that led to the Cave Bear's extinction approximately 25,000 years ago. So the cave bears went on a inflexible diet... Cave bears mostly lived in Europe during the most recent glacial period, approximately 400,000 years ago, until they became extinct...

...majestic animals, but their survival is being threatened due to climate change. Their habitat is diminishing. Polar bears need ice to move around so they can easily find food to sustain life. Some areas of the Arctic provide sea ice year-round and in other areas it melts off every year. Governments and scientists have designated 19 populations of polar bears based in four different sea ice regions in the North Circumpolar Region known as the Arctic. These four regions vary greatly when it comes to sea ice, geography and climate change (Polar Bears International, September 2017). The first area is known as seasonal ice. This is the southern...

...Polar bears are known for their vibrant white coat of fur. They have adapted this beneficial trait to help them survive and it provides the polar bear with fitness in its environments.this trait makes the polar bear white and makes them blend in with those icy surroundings. The hairs on a polar bear aren't actually white but appear white and thats what helps them blend in here's how the fur looks white,the polar bears long outer hairs that protect their undercoat are transparent and the thinner hairs are colorless as well. This makes it appear white because of the air spaces.when it reflects the colors and the light it appears white on the polar bear. The trait helps the polar bear stay safe from predators, and makes it so they can sneak up...

The reason why is that you peskey humans are using up all of my water! If I don't have any water, that means that there is no water to freese into the ice that makes up my home. If I do not have room to live, that deffinitely means I don't have any room to hunt. If I do not have any place that I can hunt from, I can not get any food for my self, And do not forget, I allso have my cubs to feed as well. If my cubs do not get fed, they will most likley die. If my cubs die its only logical to belive that other cubs would die also.If all the cubs die, then my entire species would die as well. You do not...

...surface of the water to get seals that have gotten away, and swim up to 50 miles in search of new land to start a family. These bears habitat are very special. It is because not many other bears could survive the temperatures that the Polar Bear endures. They live on the Northern Hemisphere ice caps.They are also thriving in The Hudson Bay and Greenland. Their population is increasing at a steady rate. This is an great sign for the generations to come. As you can see, Polar Bears are the coolest animals to ever walk the planet. They have come up with some very fascinating adaptations. This species deserves to be the point of many acts of preservations. Polar Bears are beautiful animals.

...Almost parallel to situation of the polar bears, the emperor penguin is also at risk of extinction. The penguin, similar to the polar bear is also a top predator in the arctic food chain that is being greatly impacted by the loss of sea ice. Just as the polar bear is starving as a result of other species dying off, the emperor penguin has also been experiencing the loss of krill. Krill, a small crustacean, akin to a shrimp, is the main food source of the emperor penguin. When the ice melts, the penguins are unable to track down krill, because the krill are unable to find a steady source of algae. This further support the notion that when one food source goes so does the one before it. An article from the Guardian expresses that “by 2100, all...

...Arctic Tribal Music “For family, for survival” "What is music?" he asked in his curious reed-like voice. "If you ask the wrong questions, you get the wrong answers”. “But I want the right questions”…. Active listening can help determine the usual characteristics of music i.e. forms, elements, and roots. But how do you know what your ears hear is music. And would you know to define it? One person’s homophonic passage is another’s minimalist rhythm. Yet one aspect is universal; it’s the fact that music plays a vital role in society. Throughout the world music is everywhere, from street corners to concert halls. It’s entertaining, stimulating, and demands an emotional response. But music can be turned off, or can it? For this group of people it can’t. As fundamental as breathing is to the human body, music is to the Native American Indian. Every facet of their existence is tied to song. And this is emphatically inherent in the Arctic Region’s Native American attitude towards song (Henceforth song is synonymous with music). As such they developed a musical identity in reference to their experiences real and perceived. The arctic region certainly one of the harshest on the planet; can sustain life albeit a difficult one. Long cold (at times totally dark) winters, and short summers (couple of months a year) meant the inhabitants had to be very flexible in lifestyle. Lite portable building materials (Tupik’s) or quick setup housing techniques (Igloo’s) were developed by the...

...Due to new scientific evidence the world could face an economic disaster, we call it Global cooling. For many decades we have come to the conclusion of the more pollution, the more the world’s temperature increases but this is all about to change. Global cooling is caused by Global Warming heating up the world and melting the ice caps. The ice caps then release fresh water, which now dilutes into the Arctic waters making it less salty. This means the Gulf Stream will no longer sink to the ocean floor and will not make its return journey to the Gulf of Mexico. As soon as the Gulf Stream switches off there is no warm air reaching the Artic. In result the temperature drops so that ice ends up covering large parts of Europe and North America. Global cooling also increases the rainfall in places like Russia. In Russia the three great rivers now empty huge amounts of freshwater into the ocean due to the unexpected heavier rainfall. Global cooling will have an immense effect on living and non-living organisms all because of the pollution exposed into the earth’s atmosphere. Yet, many people argue that global warming and global cooling is a natural issue that has nothing to do with human activity despite all of the scientific evidence to prove so. Other people believe global cooling is happening and at a very fast rate and humans are going to have to adapt to these Artic like conditions. It is very likely global cooling will take action is the world doesn’t change its ways and...

...What do migration, hibernation and stocking up all have in common? They are all techniques animals use to survive the freezing temperatures of winter. Freezing presents a serious threat to many animal species. However, what do animals do when they can’t out smart the cold? For the case of the wood frog, they simply embrace it and bring a whole new meaning to being frozen solid. Lithobates sylvaticus, or the wood frog, are found inhabiting forests stretching from the Appalachians to the Arctic Circle (Miami, n.d.). They are one of the only species capable of freezing their bodies solid to survive sub zero temperatures. This incredible adaption allows wood frogs, such as the one shown in Figure 1, to thaw and emerge unharmed after the freezing temperatures have passed. Freeze tolerance refers to an animal’s ability to survive the freezing of bodily fluids (Costanzo, Lee, Lortz, 1993). For the terrestrial hibernating wood frog, the ability to freeze completely without cell damage, is a crucial...
