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, [2] Alpine, [2] and Antarctic. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens ...
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 ...
The Arctic foothills tundra is an ecoregion of the far north of North America, lying inland from the north coast of Alaska.

[1]Russia's undiscovered petroleum is estimated between 67 billion tons of oil equivalent (BTOE) according to the United States Geological Survey and 142 BTOE according to the Russian Academy of Sciences (in 2011, the world consumed 13 BTOE of energy, 31% from ...
The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn.. Wildfires and permafrost thaw are making the tundra emit more carbon than it absorbs. From beaver ...
This coast has an arctic climate warm enough to allow plant growth in late-June, July and August only, and even then frosts may occur. On the whole this is a damper, wetter area than the Low Arctic tundra ecoregion that continues along the coast west of here to Quebec. [2]
A focus of the latest Arctic evaluation was the effects of warmer weather and wildfires on the tundra, a far-northern biome that's typically known for extreme cold, little precipitation and a ...
