Dear Coach Williams, I am visiting Yukon, Canada. The longitude and latitude for this destination is 64.2823° N & 135.0000° W. Yukon is classified as a tundra biome. The word tundra comes from the Finnish word “tunturia” which means treeless plain. The tundra biome is commonly known for its frost capped landscapes, incredibly low temperatures, and little to no precipitation. Another thing the tundra is known for is its permanent layer of permafrost, which is a subsoil and partially decayed organic matter. The arctic tundra is located in the northern hemisphere, where it is known to house the coldest places. The average temperature is 10 to 20 degrees F. The lowest temperature the tundra can reach is 60 degrees below F. It has very short growing seasons. The summer season is only a short 50 to 60 days. In the middle of summer, the sun can stay out in sight for at least 24 hours. During the summer, the temperature can reach up to 50 degrees F, as a …show more content…
There is more animal activity in the summer than there is in the winter. A large proportion of animals will hibernate in the winter, some birds will migrate South for the summer and even insects will lay eggs timed to hatch in the summer. This biome also includes a mixture of plants. Some of these plants are arctic moss, arctic willows, bearberries, diamond-leaf willows, pasque flowers and caribou moss. Dead organic material acts as nutrients for the plants to live off of. The two most important nutrients are nitrogen and phosphorus. The nitrogen nutrient is generated by biological fixation, which is the process when nitrogen gas from the atmosphere is absorbed into the tissue of specific plants. Phosphorus is generated by precipitation. Even though the soil is low in nutrients and the plants only get 6 to 10 inches of rain a year, this biome can still support is native
Blacksad: Vol 2 Arctic Nation is written by spanish author Juan Díaz Canales and drawn by spanish artist Juanjo Guarnido. The story and setting is film noir style, in late 1950s Americana with all anthropomorphic characters. The story begins when private investigator Blacksad sees a lynching of a black vulture, where he meets a reporter named Weekly (weasel), his future sidekick. It is revealed that Blacksad is working for Elementary school teacher Miss Grey, who asks to look for a missing girl named Kaylie, and tells him her suspicions that the girl was kidnapped by white supremacist group Arctic Nation. After befriending Weekly, they go to local dinner joint, where they are harassed by members of Arctic Nation. After this encounter, they are at the police station, where it is revealed that the leader of Arctic Nation
The Taiga Biome is a large, naturally occurring community of flora and fauna occupying a major part of both Siberia and North America. It is usually found at high elevations at more temperate latitudes in the Northern Hemisphere. It is the largest terrestrial biome on earth, covering around 50 million acres of land (NP, UC Santa Barbara). It is known for its subarctic climate that ranges between -51 to -1 °C in the winter and -21 to 7 °C in the summer. The two main season found in the taiga are summer and winter as autumn and spring are usually very short and barely noticeable. Winter makes up around six months of the year, with only around 50-100 frost-free days during the summer. Summer is also the season during which the taiga receives the most precipitation in form of rain. The remainder is made up of snow and dew, which adds up to around 30-85cm of precipitation yearly (NP, S.L. Woodward).
Various glaciers in Alaska and other parts of the United States have shrunk dramatically. If temperatures continue to rise, the ice will continue to melt, and some glaciers could disappear completely, which causes sea levels to rise. There are many animals, birds, and seafood that depend solely on glaciers for survival. With an increase in sea water temperature, and increasing sea levels, sea-plants that these fish thrive on will be lost, lowering the number of seafood, which in-turn will make survival of many species difficult. The arctic is source region for cold ocean currents and with no ice it will have no density and temperature distinctions, which pushes the ocean currents. If the ocean current heat transfer mechanism powers down,
The Teton Wilderness borders the south end of Yellowstone, the western side of Washakie Wilderness, the eastern side of Grand Teton National Park, and the northern region of the Mt Leidy Highlands. This wilderness area spans for 584,708 acres and is located in the state of Wyoming. The Continental Divide runs straight through Teton Wilderness which constructs one of the most interesting hydrological features across the country. This feature is called Two Oceans Pass. The reason why this place is so amazing is because there is a place where water is actually covering the Continental Divide which allows fish to swim from the Pacific Ocean to the Atlantic Ocean drainages. This wilderness area is managed by the Forest Service, and it was declared a wilderness area by Congress in 1964.
Some of these landforms include the following: hummocks, or knolls, frost boils, and earth stripes. Another common area to the alpine tundra is a “bare rock covered ground” also known as fell fields, in which not only support but helps the growth of lichens. The many “microhabitats” given by these landforms provide a variety to the tundra’s landscape. As you already know, the amount of different plant species in the tundra is very small. Also, their growth level is low, “with most of the biomass concentrated in the roots”.
Livestock in this region include cattle, pigs, poultry, etc. There are also vegetables such as wheat, barley, oats, flax, canola, mustard, potatoes, corn, and sugar beets. In the Interior Plains, during winter it is cold and lasts long. In summer, it is hot and lasts short. Winters in the Interior Plains can go as cold as -30°C and summers can be as hot as 30°C. The reason why it can get very cold in winters is that this region is near a cold ocean current. Interior Plains get the least precipitation in comparison to the other regions of Canada. This is because the westerly winds travel in the direction of west to east and the majority of the Interior Plains region is on the leeward side of the mountain. When moist air is forced to rise, it causes precipitation on the windward side. However, after the precipitation on the windward side occurs, there is only a little moisture in the air on the leeward side. This causes low precipitation on the leeward side of a mountain, where most of the Interior Plains are, especially south-western areas. Approximately, the amount of precipitation in this region is between 300mm and 500mm. South-west Interior Plains is the driest area of the region. On average, there

Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturia, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. Tundra is separated into two types: arctic tundra and alpine tundra.
Canada’s arctic has evidently suffered from substantial climate change, resulting in devastating impacts on all systems in the north. Many climate models indicate that these significant changes will only progress in the future. The monitoring of temperatures in the Arctic have demonstrated that, over roughly the past 50 years, there has been a warming of about 2 to 3°C as of 2009. The average temperature in the arctic has increased almost twice as fast than the rest of the world. In 2020, the projected increase is up to 4°C as well as 8°C by 2050. A numbers of studies have shown that, based on previous climate records, there has been issues of rising sea levels, alterations in sea-ice dynamics, and permafrost degradation. Though there have been multiple strategies posed and adopted, the government of Canada needs to develop an arctic strategy that is more proactive and systemic than previous actions. This strategy needs to be global in its goals for mitigation while still monitoring social, cultural, and economic aspects
The tundra is known for its’ cold temperatures, but also its’ limited plant species. The growth of the vegetation is primarily low to the ground and the biomass of plants is concentrated in the roots. Here the plants reproduce more likely by division and building than by flower pollination. Some of that growthforms that you will find in the tundra include tussock, mats or cushion plants, rosettes, and dwarf shru...
It is an unquestioned fact that the climate is changing. There is abundant evidence that the world is becoming warmer and warmer. The temperature of the global land average temperature has increased by about 8.5 degrees centigrade from 1880 to 2012 (Karr, et al 406). The one or two degrees increase in temperature can cause dramatic and serious consequences to the earth as well as humans. More extreme weather occurs, such as heat waves and droughts. The Arctic Region is especially sensitive to global climate change. According to the data in recent decades, the temperature in the Arctic has increased by more than 2 degrees centigrade in the recent half century (Przybylak 316). Climate change has led to a series of environmental and ecological negative
