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 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 ...
Alpine grasslands are common enough around the world to be categorized as a biome by the World Wildlife Fund. The biome, called " Montane grasslands and shrublands ", often evolved as virtual islands, separated from other montane regions by warmer, lower elevation regions, and are frequently home to many distinctive and endemic plants which ...
Consisting of the arctic, alpine, and Antarctic regions, and stemming from the Samer language, tundra literally means a "high and dry place". The arctic tundra has an exceptionally short growing period, minimal sunlight, and limited resources, creating a brutal environment for plants and animals.
Mount Elbert rises through multiple biotic zones, with alpine tundra at its peak.. The Rocky Mountains range in latitude between the Liard River in British Columbia (at 59° N) and the Rio Grande in New Mexico (at 35° N), and in height up to the highest peak, Mount Elbert at 14,440 feet (4,400 m), taking in great valleys such as the Rocky Mountain Trench and San Luis Valley.
Because the Gulf Stream has a moderating effect, portions of Iceland have an Oceanic climate (subpolar variety) (Köppen climate classification: Cfc).But most of the ecoregion is Tundra climate (Köppen climate classification: ET), a local climate in which at least one month has an average temperature high enough to melt snow (0 °C (32 °F)), but no month with an average temperature in excess ...
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]
