Adaptation of Arctic Fish Essay

commonly known as the Arctic Wobbegong, just like every other reproducing organism on this planet, goes through a process called natural selection. One adaptation of this particular organism is the ability to camouflage to the sand of the Arctic Ocean with lighter colored flesh [in comparison to its nimble yet sluggish cousin the Japanese Wobbegong]. The genetic variations of this adaptation are flesh tones that are the same color of, lighter or darker than the sand of the Arctic Ocean; which is uniquely

spectrum of beings from all the six kingdoms of all living things (Plantae, Animalia, Fungi, Protista, Eubacteria, Archaebacteria) that are the product of millions of years of evolution – “the greatest show on earth” (David Attenborough). The icon of the Arctic, the polar bear is a tribute to the theories of evolution by natural selection that have been created by many scientists, specifically; Charles Darwin, Jean-Baptiste Lamarck, Alfred Russel Wallace, Ernst Haekel and Theodosius Dobzhansky.

near the Arctic within the Northern Hemisphere, the soil may be frozen all year up to a few feet, which allows no tree growth. However, a few animals have adapted to these conditions. These animals include lemmings, hares, oxen, foxes, wolves, and more. Within the tundra biome there are two different types of tundra biomes, arctic tundra and alpine tundra. Arctic tundra can be found circling the North Pole and reaching far enough south to reach the coniferous forests of the taiga. The arctic tundra

Arctic fox Facts Arctic fox is the smallest member of canine family. There are 5 subspecies of arctic fox that inhabit tundra throughout the Arctic Circle. Arctic fox can be found in Iceland, Greenland, Northern Europe, Russia, Canada and Alaska. These animals are numerous everywhere, except in Scandinavia. They were overhunted in the past because of their beautiful pelt. Even though arctic foxes are protected by law today, their number still drops due to climate changes and because of the expansion

This article talks about how the Arctic Ocean is being affected by climate change. Because of greenhouse gas emissions, the PH of the water is lowering, its glaciers are melting which is causing a rise sea levels, and many species are becoming vulnerable. A mineral called aragonite, which is a form of calcium carbonate, is found in the water and helps organisms build their exoskeletons. As the Arctic’s water becomes more acidic, it loses more and more of this mineral, which threatens the lives of

climate change on Arctic ecosystems. Markedly, the major concern of the study is the expectation that the Arctic region will face adverse effects of global warming than other biomes because the Arctic is more susceptible to these impacts of climate change. This explains the phenomenon of the vulnerability of the arctic zones to the climatic changes observed today. The effects of climatic changes have impacted on the arctic vegetation, arctic animal life, and life in the arctic seas. According to

aquatic life. For instance, fish normally thrive and reproduce in cool waters. Global warming results in a very high rise in temperatures; however, the effect is not normally felt since water covers more than two-thirds of the earth’s surface and therefore absorbs much of the rise in temperature. The Ocean temperatures have therefore risen to very high levels that are not conducive for reproduction of fish; this has resulted in a significant reduction in the population of fish species with others becoming

the environment and decrease the population, eventually causing extinction. In some cases, species have found a way to adapt to the environment through genetic changes caused be evolution. The mechanisms of phenotypic resilience and evolutionary adaptation allows species to obtain the potential to adapt to warmer environments. Phenotypic resilience is where the species possess the ability to portray different phenotypes in a changing environment. In animals, the traits that respond to selection are

Paper Assignment Subject Point of Significance Arctic National Wildlife Refuge Should be protected from oil drilling Dear President Barack Obama: As you may be aware, some of your Congressmen are wanting to drill for oil at the Arctic National Wildlife Refuge (ANWR). The main "Arctic National Wildlife Refuge Drilling" article on Opposing Viewpoints Online Collection, said that US House of Representative passed yet another bill to drill oil in the Arctic National Wildlife Refuge in February of 2012

When I visited the center on friday, I visited the whole center, with the exception of the new exhibit called the Body World: Pulse. During my visited I learned the difference between the Arctic and Antarctica and how both are typically confused because they are both cold, windy and dry. However, the Arctic is ocean surrounded by land and Antarctic is land surrounded by ocean. Besides, geographical differences, population is
