Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra .
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.
The tundra region is found in high latitudes, primarily in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, as well as the Antarctic Islands. Consisting of the arctic, alpine, and Antarctic regions, and stemming from the Samer language, tundra literally means a "high and dry place".
The Interior Yukon-Alaska alpine tundra ecoregion (WWF ID: NA1111) covers alpine, sub-alpine, and boreal forest areas along the cordillera (chain of mountain ranges) of Interior Alaska and south-central Yukon Territory. Geologically, they are the disjunct uplands of the Yukon-Tanana Terrane plus a southern extension of the Brooks Range. The ...
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 ...
Páramo in Colombia. Páramo (Spanish pronunciation:) may refer to a variety of alpine tundra ecosystems located in the Andes Mountain Range, South America. Some ecologists describe the páramo broadly as "all high, tropical, montane vegetation above the continuous timberline". [1]
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 ...
