This effect predicts that zonation of rain forests on lower mountains may mirror the zonation expected on high mountains, but the belts occur at lower elevations. [3] A similar effect is exhibited in the Santa Catalina Mountains of Arizona, where the basal elevation and the total elevation influence the elevation of vertical zones of vegetation ...
The general effect of elevation depends on atmospheric physics. However, the specific climate and ecology of any particular location depends on specific features of that location. This article provides a list of life zones by region, in order to illustrate the features of life zones for regions around the globe.
[1] [4] [5] Scientists at the High Altitude Pathology Institute in Bolivia dispute the existence of a death zone, based on observation of extreme tolerance to hypoxia in patients with chronic mountain sickness and normal fetuses in-utero, both of which present pO 2 levels similar to those at the summit of Mount Everest.

The eight-thousanders are the world's deadliest mountains. The extreme altitude and the fact that the summits of all eight-thousanders lie in the Death Zone mean that climber mortality (or death rate) is high. [31] Two metrics are quoted to establish a death rate (i.e. broad and narrow) that are used to rank the eight-thousanders in order of ...
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 Sierra Nevada subalpine zone occurs between 2,450–3,660 metres (8,000–12,000 ft), and is characterized by an open woodland of several conifer species, including whitebark pine, lodgepole pine, western white pine, mountain hemlock, and Sierra juniper. The vegetation and ecology is determined by the harsh climate, with extensive snow and ...
White Mountain, an alpine environment at 4,300 metres (14,000 ft) above sea level in California. Alpine climate is the typical climate for elevations above the tree line, where trees fail to grow due to cold. This climate is also referred to as a mountain climate or highland climate.
The Rocky Mountains subalpine zone is the biotic zone immediately below tree line in the Rocky Mountains of North America. In northern New Mexico, the subalpine zone occupies elevations approximately from 9,000 to 12,000 feet (2,700 to 3,700 m); [1] while in northern Alberta, the subalpine zone extends from 1,350 to 2,300 metres (4,400 to 7,500 ...
