Altitudinal zones of Andes Mountains and corresponding communities of agriculture and livestock raised. Human populations have developed agricultural production strategies to exploit varying characteristics of altitudinal zones. Elevation, climate, and soil fertility set upper limits on types of crops that can reside in each zone.
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 life zone concept was developed by C. Hart Merriam in 1889 as a means of describing areas with similar plant and animal communities. Merriam observed that the changes in these communities with an increase in latitude at a constant elevation are similar to the changes seen with an increase in elevation at a constant latitude.

Jewish Americans and Israeli Americans experience "serious discrimination" when applying for jobs, a shocking study released by the Anti-Defamation League Wednesday claims.
As stated in the UNESCO description of the site, "the region represents the most complete sequence of altitudinal vegetation zones in central Siberia, from steppe, forest-steppe, mixed forest, subalpine vegetation to alpine vegetation". [1]
Jackson's "Jam," the lead track on "Dangerous," sounded a lot like Sonic 3's "Carnival Night Zone," Mallinson -- aka "Ben2k9" -- argued. The teenager's post would captivate the Blue subculture for decades. But the Blues' obsessiveness may have harmed their cause.
