In Ethiopia the gelada (genus Theropithecus) is found living at elevations up to 5,000 metres (16,000 feet).
They studied 43 species living at elevations from 1,300 to 14,000 feet in the Peruvian Andes, videotaping specimens as they hovered and as they lifted small weights.
The thin mountain air can cause a slew of health problems, even for people who have lived at elevation for centuries.
Boreal toads are found at elevations of between 7380 and and the Columbia spotted frog can live at elevations as high as 9480 feet in the Greater Yellowstone Ecosystem.
It is perfectly obvious, of course, that the basic cause of this has been the rise in living standards the widespread elevation of the scale of creature comforts that prove satisfying to the average man.
At the same time, adaptive genetic differences are present in these same traits: human populations from areas with more sun exposure have genetically darker skin (Jablonski 2004) and human populations living at high elevation have evolved several mechanisms to increase oxygen uptake and transport (Beall 2006).
In addition, studies in other low-income, developing contexts with inadequate sanitation have shown that living at low elevation is often associated with low SES, as a consequence of the flooding and disease risk these areas are often subject to (Baker et al., 2011).
The study area for the RESPIRE project comprised 23 rural villages spread over an area of about 94 km in the towns of San Lorenzo and Comitancillo, San Marcos, in the western highland region of Guatemala, home to a primarily agricultural indigenous population living at an elevation of 2,200 3,000 m above sea level.
All the well-known high-altitude "experts," he noted, with some bitterness, live at elevations below four thousand metres.
They live at elevations of 3,000 to 6,000 feet (900 to 1,800 m) in houses built on pilings.
