These complex interactions between plants, animals and abiotic factors in the tundra are held together by the permafrost layer, located 450 metres (1,480 ft) under the soil. [3] However climate change is causing this crucial layer of frozen soil to melt. As a result, tundra communities are becoming unstable and basic processes are breaking down.
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.
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 maximum elevation is 1,633 metres (5,358 ft). The ecoregion to the north on Baffin Island is the Davis Highlands tundra, which receives more than twice as much precipitation (400-600 mm/year). [6] The terrain varies across the ecoregion. The north and west is mountainous and heavily covered in ice.
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 ...
This species nests in June–July on coastal areas in the tundra, choosing locations with grass close to freshwater pools. [6] Spoon-billed sandpipers feed on the moss in tundras, as well as smaller animal species like mosquitoes, flies, beetles, and spiders. At certain points in time, they also feed on marine invertebrates such as shrimp and ...

The region is strongly influenced by the large mountain ranges stretching throughout most of the coast. Changes in elevation cause changes in plant/animal diversity, this can be exemplified through observing the alpine tundra's vegetation which consists of shrubs, herbs, mosses, and lichens; while lower elevations, the temperate coastal forest hold magnificently large trees such as western ...
