Its habitat, known as tundra, is cold all year round. Even in the summer, when it’s warm in other places, the tundra has a temperature that’s maximally 45°F ( 7.2°C).
The adversity of soil and climatic conditions proves to low production levels, as well as little biomass accumulation due to slow rates of nutrient release in cold and wet soils, specifically as a result of limited nitrogen and phosphorus (Nadelhoffer et al. 1996) Additionally, there are low temperatures and strong winds in the tundra causing most vegetation to be dominated by woody plants ...

In physical geography, tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic tundra, [2] alpine tundra, [2] and Antarctic tundra. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses ...
Rising temperatures also lead to increased precipitation in the Arctic, which can be a big problem for the tundra because it can cause layers of hard ice to form and cover the ground. This layer ...
Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2]
Alpine tundra occurs at high enough altitude at any latitude.Portions of montane grasslands and shrublands ecoregions worldwide include alpine tundra. Large regions of alpine tundra occur in the North American Cordillera and parts of the northern Appalachian Mountains in North America, the Alps and Pyrenees of Europe, the Himalaya and Karakoram of Asia, the Andes of South America, the Eastern ...
The tundra has become a source of emissions, rather than a carbon sink, the authors said. The Arctic is heating up far faster than places at lower altitudes as melting ice reflects less radiation ...
