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 ...
[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 climate and ecology of different locations on the globe naturally separate into life zones, depending on elevation, location, and latitude.The generally strong dependency on elevation is known as altitudinal zonation: the average temperature of a location decreases as the elevation increases.
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 ...
The summit of K2, the second highest mountain on Earth, is in the death zone. At an altitude of 19,000 m (63,000 ft), the atmospheric pressure is sufficiently low that water boils at the normal temperature of the human body. This altitude is known as the Armstrong limit.
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 lowest-elevation biotic zone in the Sierra Nevada is found along the boundary with the Central Valley. [5] This zone, stretching in elevation from 500 to 3,500 feet (150 to 1,070 m), is the foothill woodland zone, an area that is hot and dry in the summer with very little or no snow in the winter. [5]
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.
