The Arctic fox has multiple adaptations to help it survive the same. Compared to other fox species, the Arctic fox has relatively shorter necks, legs and ears(structural adaptation). With a smaller surface area exposed, less heat is lost when compared to the more lanky Southern Foxes. The southern foxes are 25% larger that their Arctic counterparts, and thus unable to survive the harsh Arctic weather. Additionally, the Arctic fox also has a thick and insulating coat, including on the tail.
One of the most well-known vulnerable bear species is the polar bear, these bears are found exclusively in the arctic across Alaska, Norway, Canada, Greenland and Russia. Polar bears are seen along the coasts and on islands, they are very often found out on the ice across the sea. These bears feed mostly on seals and so the ice is of huge importance out at sea, polar bears travel across this ice while looking for seals between the gaps and spaces. Polar bears are extremely strong swimmers and can travel kilometres in distance searching for suitable spots to try and feed, although they are strong swimmers they are not fast enough to keep up with seals
The Arctic Moss grows in harsh conditions. The average winters are -25 celsius and in summers, it is about 10 celsius. The Arctic Moss is nearly 70% covered in permafrost. The frozen soil prevents water from sinking into the ground. This causes the ground to form small pools of water during the summer.
Despite being one of the coldest, most inhospitable places on Earth, Antarctica hosts a wealth of biodiversity. A variety of species use the extreme climate and remoteness of the continent and its surrounding waters as a sanctuary and protection from predators. The Antarctic has not been immune to human influences and climate change, however, and its flora and fauna is suffering from a range of negative effects triggered by climate change. The polar regions are experiencing more dramatic changes than anywhere else on the planet in consequence of climate change and global warming. In Antarctica, climate change is having a range of impacts.
Most of the time plants or organisms within the snowpack also influence on the colour of the snow. For example, Watermelon snow look as if its colour is either red or pink. This colour is due to a form of cryophilic which is a cold loving and fresh water algae that has red pigment in it thus appears red. It is usually found in high alpine areas or along the coastline of polar areas. Snow is a great insulator.
As the world we live in today continues to warm up, the problems surrounding the survival of the world’s beloved polar bear continues to grow. Over the past twenty years, we’ve seen a change in the number of polar bears in the Arctic and have witnessed a decrease of the amount of Arctic ice in the sea. Many scientist have come up with ideas to tackle the problem, but there hasn’t been a solution that has greatly influenced the predicament at hand. Ultimately, when discussing what to do about the endangered animals, it is valuable to consider what the species needs in order to remain; a healthy population and genetic diversity. Andrew Derocher, biologist at the University of Alberta, and the rest of his team have come up with a few ways to combat these needs.
Mr. Tompkins claims that things like growth rate of calves, social structure and social status among others would be difficult to learn in the wild. While it may be difficult it is not impossible, studies such as these have been done. A dorsal fin is a unique structure to each whale, much like a fingerprint, a scientist who has followed a pod can tell the different orcas apart easily. Observing orcas in their natural settings, taking picture of their dorsals are all ways to document growth and social structure. A professional in the field can look at a photograph or animal in the distance and be able to know the approximate size of the animal.
One of these mechanisms is a train. These fast moving machines help humans travel through rural and secluded areas faster, but kill many animals that enter its path and emit harmful smokes and smells. “...-while leading the pursuit of the fugitives, had been run down on the iron road by a train” (Adams pg 308) Granting all this, Adams still shows that sometimes humans try to help animals. One example is when a rabbit named Woundwort had just lost his mother and was alone in the woods. A man walking by had noticed him and instead of killing it upon sight, took him home, nursed him back to health, and let Woundwort live with him.
Perhaps Natural Selection will result in a small number of chosen species, but it affects every existing animal in order to allow it to reproduce in future years. An interesting animal to analyze would be the elephant, what could make better fit from others if they all look the same? These mammals are indeed affected by the mechanism, because they must have physical adaptations that allow them to inhabit warm places like Africa and Asia. Elephants must have strong tusks, as Dr. Joyce Poole ( 2016) states that “ their tusks are important for obtaining food and water, and essential to male elephants for competing for mates, so there is strong natural selection for having tusks.” Rarely, 2-6% of female elephants are likely to never grow them, which makes that small number have a disadvantage in order to allow nature to pass on their traits to future generations (Op. Cit.).
There are a lot of amazing animals live in Arctic, like the Arctic wolf, orca, snowy owl, polar bear..etc. But, because of the global warming problem and climate change, Arctic got damaged. The location of Arctic makes the global warming impact super effective on
