Characteristics of the Arctic Tundra Arctic tundra is found in the northern hemisphere, it encircles the North Pole and branches South the the taiga coniferous forests. Moisture affects thermal characteristics and oxygenation of soils, which in turn affects decomposition rates and the availability of mineral nutrients. Characteristics of the Tundra Biome. Wet tundra is characterized by permafrost below the surface, few if any trees, and a variety of lichens, mosses, heath plants, and an assortment of wildflowers growing on dry tussocks. Words or phrases that summarize certain aspects of the data. The vegetation of many alpine tundras and over most of the Arctic tundra tends to be greenish brown in colour. Tundra Plants Rising to the challenge of harsh environments and conditions. The habitat has a long and brutal winter and the barren landscape provides many challenges. Thus, based on variations in the general characteristics of vegetations in the arctic tundra (tun­dra biome is divided in two sub-divisions e.g., arctic tundra biome and alpine tundra biome where the latter is found over high mountains of tropical to temperate areas). Tundra plants need to grow fast during the limited am… Tundra Ecosystem Characteristics. Mosses, lichens, and low-growing woody and herbaceous perennials characterize Arctic vegetation. There are two types of tundra, the arctic and the alpine tundra. Arctic plants are also adapted to their biotic environment. This weird tundra plant loves bogs, wetlands, and very moist landscapes. Arctic flora and fauna: status and conservation. Trees are very scarce. Pielou EC. Permafrost is a permanently frozen sublayer of soil. There are only two native vascular plants in Antarctica: Antarctic hair grass and Antarctic pearlwort. Usable soil is limited by permafrost, and low temperatures retard soil genesis, microbial activity, and uptake by roots. A layer of permanently frozen subsoil called permafrost exists, consisting mostly of gravel and finer material. The tundra is located in the Arctic Circle and Antarctica, especially in the Northern Hemisphere. Typical tundra plants include lichen, moss, sedges, grass and shrubs. Contact information for the individual or organization distributing the data. The Arctic poppy is a plant known for its delicate flowers and heliotrophic nature. Arctic ecosystem, US/IBP synthesis series, vol. Physiological plant ecology (39th symposium of British Ecological Society). In: Scholes JD, Barker MG, editors. Stroudsburg: Dowden, Hutchinson and Ross; 1980. There are relatively few species of organisms that can survive in an environment like the tundra. The maximum height, which can be attained by the Arctic poppy is around 25 cm. Nuttall M. Encyclopedia of the Arctic. This is a preview of subscription content. These conditions make the Arctic tundra a desert-like climate ( see climograph ). Bliss LC. Tundra ecosystem experiences extreme cold almost throughout the year. Bladderworts. Adaptations of Arctic plants to cold and short growing seasons as well as other aspects of their physical environment are evident in their morphologies, physiologies, and life histories. the abiotic conditions), most shrubs do not grow more than a few feet tall and are not significant in size. The state of and maintenance information for the data. The southern boundary of the Arctic tundra follows the northern edge of the coniferous forest belt. Arctic plants exist along a global continuum of decreasing floristic diversity with increasing latitude. A tundra is a biome characterized by cold weather and low growing plants and shrubs. it can... Lichens. Three zones are recognized from south to north viz. and the short growing season, there are approximately 1,700 kinds of plants that live in the Arctic tundra. From a biological perspective, there is no universally accepted definition of the Arctic, but Arctic plants are generally considered to be those living in tundra and polar deserts beyond the northern climatic limits of forests, i.e., generally north of the boreal zone. The Arctic tundra’s locations are at the far Northern Hemisphere, north of the taiga belt. Not logged in Once used by the Inuit as a candle wick, the cotton grass was collected, dried, … Cambridge: Cambridge University Press; 2008. The fauna in the arctic is also diverse: It can grow up to 15 centimeters high and is rigid with... Purple Saxifrage: Like the Tufted Saxifrage, the purple grows in low, tight clumps. The tundra contains mostly frozen landscape and the soil is frozen from 25-90 cm down. Helsinki: Edita; 2001. p. 272. The arctic tundra is the land around the North Pole. Other examples of plant-life found in the hot and dry desert include prickly pears, yuccas, and agaves. The arctic is known for its cold, desert-like conditions. The Antarctic tundra, a variation of the Arctic tundra, features similar abiotic factors as the Arctic tundra yet supports far fewer biotic factors. Information about events, parameters, tolerances and techniques applied to construct or derive the data. Oxford: Oxford at the Clarendon Press; 1959. This poor precipitation makes short growing seasons for the plants. In the arctic tundra there is very low precipitation only about 15 to 25 cm annually.This includes rain and ice/snow. Part of Springer Nature. A biome is made up of many ecosystems. These keywords were added by machine and not by the authors. Cite as. Arctic ecosystems of North America. Trees, succulents, ferns, and annual plants are rare or absent from most Arctic plant communities. © Springer Science+Business Media New York 2014, http://www.caff.is/publications/view_document/167-arctic-flora-and-fauna-status-and-conservation, https://doi.org/10.1007/978-1-4614-7501-9_13, Reference Module Biomedical and Life Sciences. Because of the climate, permafrost and short summers, tree species such as birch and willow are ground cover—they grow horizontally, not upwards, in this biome. Stanford: Stanford University Press; 1968. Hulten E. Flora of Alaska and neighboring territories: a manual of the vascular plants. Crawford RMM. Wet tundra is mostly found in areas of arctic tundra throughout the sub-Arctic. Although the Arctic is climatologically a desert, few Arctic plants experience water stress. Location: The arctic tundra can be found in the northern parts of North America, Europe, and Asia. This service is more advanced with JavaScript available, Ecology and the Environment Even they grow in water. Plants at the margin: ecological limits and climate change. This gradient starts well outside of the Arctic and continues within the Arctic to the northernmost reaches of land. There is very little rain or snow in the tundra, usually less than 15 inches a year. Combinations of mosses, lichens, sedges, grasses, and dwarf woody shrubs dominate most Arctic tundra, and miniature flowering plants dominate the polar deserts. As Antarctica’s only region without permanent ice cover, the Antarctic peninsula reveals an arid, rocky landscape in its short summer that is capable of nurturing only two species of flowering plants: Antarctic hair grass and Antarctic pearlwort. Birds and mammals play a key role in nutrient redistribution and the creation of local sites with high fertility. It is very difficult, if not impossible, to anticipate the effects of a changing climate on the Arctic due to the diversity of plants and habitats and due to nonlinear interactions between environmental factors within Arctic ecosystems.
