With less than 10 inches of rain in a year, it is also the driest. Teaching about biomes (including the tundra) can meet a wide variety of fundamental concepts and principles, including: K-4 Life Science. Although in some parts of this region, willows do grow, they can grow only up to about 8 cm, or 3 inches high. A University of Michigan study of the North American Great Lakes recommended blue-joint grass, wire-grass, purple loosestrife and wild rice as among the indicator plants used as lake-level indicator species. Animal muy característico de la tundra alpina, donde viven bien adaptadas a las bajas temperaturas gracias a su pelaje, gran cola y orejas de tamaño reducido. The jackrabbit and the california lilac are two examples. The most commonly found fish are the trout, salmon, flatfish, and cod. The tundra is characterized by very low temperatures, very little precipitation (rain or snow), a short growing season, few nutrients, and low biological diversity. Sea birds and sea mammals, such as penguins and seals, however, do occur in areas close to the shore, while small mammals, like cats and rabbits have been introduced by humans on some of the sub-Antarctic islands. Marmots are large squirrels that are found in the alpine tundra zones of mountain ranges in Europe, Asia, and North America. This phenomenon is caused when the sun does not disappear entirely below the horizon point. The midnight sun can be seen in the summer season in the Arctic region. Tundra is one of the important ecosystems found on the planet. The tundra, like other biomes on Earth, contains a distinct set of resources. This is the primary reason to explain why trees cannot survive in the tundra region. The flowering plants remain short, grass and moss and lichens survive better near the ground. Some of the smaller mammals are lemmings and snowshoe rabbits. Some of the commonly seen plants of the tundra ecosystem include lichen, sedges, shrubs, moss, liverworts, grass, various flowers, etc. Out of these cookies, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website.

During summer, mosquitoes are quite common to see in wetland areas of the tundra region. The midnight sun is a phenomenon commonly seen in the Arctic Tundra ecosystem. Therefore, small shrubs are visible in the Alpine tundra region. Different species of animals become more active in summer, especially that comes from hibernation and migration from the south. The animals of the Arctic tundra ecosystem include a snowy owl, reindeer, polar bear, lemmings, wolverines, black flies, white foxes, etc. It is categorized in this group since the mean temperature never goes beyond 10 °C (50 °F). Here, migratory marine and land animals sustain the local populations. Required fields are marked *, Before going into characteristics of tundra ecosystem, we will go through two types of tundra regions found on Earth – Arctic Tundra region and Alpine tundra region –. The harsh climate of the tundra imposes such formidable conditions on life that only the hardiest plants and animals can survive in this environment. The countries that witness the phenomenon of midnight sun include Finland, Greenland, Sweden, Canada, Norway, Iceland, Denmark, Russia, etc. Alpine tundra region can be found in high mountain tops above tree line anywhere across the globe. Tundra - Tundra - Biological productivity: An important measure of natural ecosystems is the biological production of its plants and animals—that is, the total amount of biomass produced by living organisms within a given area in a specific period of time. Alpine tundra animals There have been a total of 48 different species of animals living in the tundra biome. Tundras are places of extreme cold temperatures that are located on the far northern edges of Asia, Europe, and North America, high mountains of the middle latitudes, and the far southern regions of Oceania and South America. Animals of all sizes have adapted to harsh weather conditions and long winters of the tundra. The mosquitoes that occur prevent themselves from freezing by substituting the water in their bodies with glycerol, which acts like an anti-freeze. Locals hunt many species, … Animals of the Tundra Animals of the tundra, like this caribou, are well adapted to the cold and dry weather. The tundra is one of the harshest biomes and it is definitely the coldest! The tundra region is the coldest biome existing on Earth. Various characteristics of tundra ecosystem is given below in points –. However, alpine and arctic tundras do have some things in common like the animals and tundra plants which are able to survive there. The plants growing in the alpine climate and at a higher elevation (above the tree line) are called alpine plants. Tundra is a vast, treeless landscape that covers almost 20 percent of Earth’s surface. Tundra - Tundra - Animal life: Organisms of the northern alpine tundra probably evolved before those of the Arctic tundra, appearing first in the Mongolo-Tibetan Plateau. Organisms have basic needs. The limit for arboreal vegetation, the trees are bare on the side that the wind blows. The Arctic tundra region is found between the North Pole and the taiga region (also known as coniferous forests). They play a vital ecological role, especially in the Arctic food chain. On the other hand, the Alpine tundra region is a bit warmer as compared to the Arctic tundra region. Unlike Arctic tundra, Alpine tundra is covered with snow for most of the year rather than frozen year-round. It occupies the Sweden, Russia, Norway, and Finland regions of Europe. Animals in the tundra must be adapted to cold and dry conditions. Of all the biomes in the world, this region is considered to be the coldest. Many animals have shorter legs and ears to minimize exposing their skin to the cold. This is the landscape of the Arctic zone in America, in Europe and Asia, where the climate is dry and cold. Lemmings are a small, short-tailed, thickset rodents, found in the Arctic tundra. Read on to understand the biome of these forests…. The world’s major habitats characterized by the dominant forms of plant and animal life along with the climatic and geographical conditions are known as biomes. Antarctic Tundra It occurs on various Antarctic as well as sub-Antarctic islands, which include the Kerguelen Islands, the South Sandwich Islands, and South Georgia. Smaller musk-oxen herds also roam about the frozen regions. Kilimanjaro), and in Asia, it occurs in the Himalayan Mountain Ranges — which are located in Southern Asia, and in Mt. During the summer season, the permafrost partially melts, creating small ponds on the topmost layer of permafrost. 6789 Quail Hill Pkwy, Suite 211 Irvine CA 92603. In the western and northern parts of the Antarctic Peninsula, flowering species of plants known as the Antarctic pearlwort and Antarctic hair grass can be found. The Alpine tundra ecosystem is commonly experienced in these regions – North America (Alaska, Canada, USA, Mexico), Northern Europe (Finland, Norway, Russia, Sweden), Asia (Southern Asia (Himalayan Mountain), Japan (Mountain Fuji), Africa (Mountain Kilimanjaro), South America (Andes Mountains), etc. Copyright © Science Struck & Buzzle.com, Inc.
