Research Paper On Tundra

The tundra is by far the coldest type of biome, as it is known for its low temperatures, little precipitation, poor nutrients, and short growing seasons. Occurring primarily 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.

In which mosses, lichens, and other shrubs thrive on hills and valleys in the tundra (National Geographic). Permafrost, which acts a layer of snow on the land, remains frozen year round, with the exception of summer, when the top layers thaw, while the bottom layers remain frozen (National Geographic). These soil conditions greatly hinder soil development. Despite the short growing season, plants in the tundra have learned to adapt through various ways such as, a) grouping together to resist the strong winds of the tundra, b) learning to photosynthesize in low temperatures and light intensities, while using the minimum amounts of energy and c) reproducing by less energy dependent ways (Kids Do Ecology). Like plants, animals who call the tundra home, such as caribou, arctic hares, squirrels, wolves, and polar bears, ravens etc. have also learned to adapt to life in the tundra. They have developed the ability to breed and raise their young during the summer, accumulate fat that serves as insulation, hibernate when food sources are limited, and/or migrate to other areas during the winter months (University of California Museum of Paleontology). In spite of the tundra’s frigid climate, the frozen desert still manages to have a thriving food chain from beginning to end, with producers, herbivores, omnivores and

I chose the song Tundra by Ola GJeilo because of its unique sound. The song sounds like no other song, and it is very original in my perspective. The song is performed beautifully by this choir, and it has a lot of potential. This song is a short, yet sweet piece that shows the beauty of Norway. This song exemplifies how poetry can be turned into music.

The tundra is one of the cooldest land biomes on the planet. Due to the high winds and the permafrost there are no trees becuase it dosent allow the growth of deep roots. All the producers and othe need to get adapted to the cold temperatures, little sun and short growing season to stay alive. The tundra is considered a poor enviroment thats low in resources. The dead minerals get recycled by othe decomposers like the slime molds, fungi, and bacteria. Rain increases photosynthesis and decomposition. Air pollution kills lichen in the cold tundra. The warmer climates allow trees to invade the shade out the small tundra plants. And warmer temperatures can increase decompositon, while releasing more CO2 into the air causing mor global

The Earth's rise in temperature is melting ice in its colder regions. Many animals who live in the Arctic Circle, the lands surrounding

The muskox can survive in the tundra due to its large coat of rough hair on its body. It lives in the tundra to find what it needs to stay sustained such as roots, mosses and lichens.Next the Arctic Hare survives in the tundra because it has shortened ears and limbs, a wad small nose, fat that makes up 20% of its body, and a thick coat of fur. It live in the Tundra because that is its place of origin.Third the Polar Bear survives in the tundra because it has a big fur coat over a thick warm coat of fat. It stays in the arctic or tundra due to those locations have the food source they need to survive.Fourth the Arctic fox survives in the Tundra because the furry soles, short ears and short muzzle which are good for chilly climates. They stay

The biggest threat to the tundra is from oil and gas development that results in global warming. As the planet warms the permafrost melts and tundra ecosystems will collapse. Another, threat comes from airborne pollutants, which have brought measurable levels of pollutants such as DDT and PCB's to even remote areas because it is a great technical challenge to effect efficient sewage treatment in a cold environment. Lastly, the overpopulation of Canadian geese pose a threat to the tundra because the balance of the biome will be offset.

Permafrost is very vulnerable to changes in air temperature and different snow coverages making it extremely sensitive to climate change. As the permafrost is melting, it continues to amplify the already rapidly increasing rate of global warming because it is releasing heat-trapping elements that are stored in the soil and the ice into the atmosphere. In the Beringia Upland Tundra, average temperatures in the year 2050 are expected to be 3.5-7 degrees fahrenheit higher than what current temperatures are at now. With this happening, the permafrost will continue to melt unless humans reduce the amount of heat-trapping emissions being let into the atmosphere (Hagenstein). Through warmer climate is increased evaporation, lakes are getting severly smaller and permafrost is thinning. As the climate warms, shrubs are entering into the tundra. In some circumstances and places, shrubs are taking place of other tundra vegetation such as lichen. Caribou depend on lichens for food in the winter since the tundra does not produce much food in the winter. A decline of lichen can cause a negative slope of growth and and numbers of these animals, and can possibly lead to extinction in this region. If caribou don't survive, then other animal species in this region will not be able to evolve and thrive since caribou are a solid food source for them

Polar bears are just one kind of animal you can find on the tundra did you know the tundra is the coldest biome of them all? The climate, producers, and consumers, are all parts that make up the tundra.

The arctic Tundra is normally around 10 to 29 degrees fahrenheit. Rainfall may vary in different regions of the arctic. Yearly precipitation, including melting snow, is 6 to 10 inches. Soil is formed slowly. The biggest threat to the Tundra is global warming. Many scientists believe global warming caused by greenhouse gases may eliminate Arctic regions, including the tundras there, forever. Another concern is that about one third of the worlds soil-bound carbon is in the tundra permafrost. Cutting greenhouse gas emissions by switching to alternative energy uses is key to protecting Earth's tundra habitats. The Tundra is located at the top of the earth by the North Pole. Switch to alternative energy

This tundra region spans an area of 26 million hectares. Around 24.2% of the land is covered by slow-growing forest. The remaining area is dominated by bogs, fens, and thousands of small lakes and ponds. Two-thirds of the area in this region is covered by muskeg, a type of acidic soil.

Environmental changes due to our climate warming is causing terrible effects on the Marten population in the northern reaches of Wisconsin. What climate change is doing to the habit in which the Marten is living in is changing the amount of snowfall the regions in which the Martens are living in are acquiring. Looking at figure 3 you can see that the total snowfall in the two regions where Martens were reintroduced showed significantly less snowfall accumulation in present day compared to the 1980’s. This is extremely important to note because this change in snowfall can deteriorate the critical zone called the subnivium. The subnivium is the seasonal microenvironment underneath the snow (Pauli et al., 2013). This is a small zone where plants and small mammals thrive during the winter. It should be stated that the subnivium insulates the ground creating a pocket of warmth that allows these organisms to survive the harsh Wisconsin winters. The way a subnivium is formed is based on snow duration, density and depth (Pauli et al., 2013). But this is where climate change comes into play. It is causing snowfall to decrease, the time snow is present is decreased and the density of the snow is lower (Pauli et al., 2013). Having these three factor decline is getting rid of the refuge of the subnivium and killing organisms that thrive there. One such organism is the American Marten. These mammals are small enough to crawl down tree trunks where the snow is melted to gain access to the subnivium. This is where the Marten hunts mice and other small mammals to its heart's content. But with the loss of the subnivium Martens can’t hunt in their little paradise. They will have to find other places to hunt and find prey to satisfy their caloric needs. This is where the Fisher has the advantage, since they are too large to access the subnivium. The Fisher

In the northern part of the earth and the upper slopes of all mountains all over the world, a unique biome called tundra exists. Tundra is one of the coldest and harshest biomes of the world. The winters are long and cold, and the summers are short and cool. Tundra is far from the equator; therefore, Tundra soil is generally poor in nutrients. Since the biome is covered in snow throughout the year, the arctic tundra doesn’t seem like a place where plants and animals can survive. Yet, plants and animals are able to survive, thanks to their special adaptations. In fact, it isn’t the freezing temperature that they fear; it is us, human. Today, tundra faces lots of threats and problems because of human. One of the major problem is Global

It contains an expanse of tundra with many marshes and lagoons with rivers situated between foothills of the Brooks Range and the wide, icy waters of the Beaufort Sea. Environmentalists said that this area “is the most biologically productive part of the Arctic Refuge for wildlife and is the center if wildlife activity.” The importance of these resources is not measurable. The Arctic is home to such animals as caribou, polar bears, grizzly bears, musk oxen, whales, wolves and snow geese. This area is full of wildflowers and contains water of excellent, unpolluted quality and quantity. The Arctic Ocean costal plain is an area critical to the survival of many birds and mammals (‘Alaska Wild’).

Animals of the tundra have had to adapt to the long cold winters and to having to raise their young quickly in the summer. Some other adaptations of animals include thick insulating cover of feathers or fur; large, compact bodies; pelage and plumage that turns white in the winter and brown in the summer; the ability to accumulate thick deposits of fat during the short growing season; hibernation; and migration. Some of the animals that are found living in the tundra are lemmings, voles, caribou, artic hares, squirrels, artic foxes, wolves, polar bear, ravens, snow buntings, falcons, loons, ravens, sandpipers, terns, snow birds, mosquitoes, flies, moths, grasshoppers, black flies, artic bumble bees, cod, flatfish, salmon, and trout. Some of these animals are shared with other neighboring biomes but some are only home to the tundra. The tundra is the simplest biome in terms of species composition and food chain. The neighboring biome of the tundra is the boreal forest (taiga).
