The Andes Mountains, ... The climate is known to change drastically in rather short distances. ... For example, the main crossover of the Andes between Argentina and ...
The flora of páramos is adapted to specific conditions and is thus vulnerable to even small climate changes. Climate change in the Andes is causing glaciers in the páramo to disappear and a drop in rainfall, virtually drying up páramo and in turn, drying up the water supply for cities such as Quito, Ecuador and Bogotá, Colombia.
The Andean and Fuegan mountains intercept moisture-laden westerly winds, creating temperate rain forest conditions, while the cold oceanic Humboldt Current, which runs up the west coast of South America, and the cold Antarctic Circumpolar Current, which runs from west to east through the Southern Ocean, keep the Magellanic ecoregion cool and wet, and the strong oceanic influence moderates ...
The chain of mountains called the Andes, comprising 28 percent of the national territory, runs the length of Peru, a narrow 80 km (50 miles) wide at the Ecuadorian border in the north and 350 km (220 miles) wide in the south along the border with Bolivia. The Andes, with elevations almost entirely above 2,000 m (6,600 ft) and mostly above 3,000 ...
The Northwestern Andean montane forests (NT0145) is an ecoregion on the Andes mountains in the west of Colombia and Ecuador. Both flora and fauna are highly diverse due to effect of ice ages when the warmer climate zones were separated and the cooler ones combined, and interglacial periods when the reverse occurred.
In the past, when the climate was cooler, the treeline and the páramo units were lower and the units were connected. During the present warmer Holocene epoch the páramos have migrated uphill, shrinking and becoming isolated. They contain many rare or endangered species, some of them restricted to a narrow area of one mountain or mountain range.
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.
That the large land area shows the Tropical Andes can provide biodiversity with a diverse landscape. Many endemic plant and animal species are currently threatened in the Tropical Andes. An example of a threatened plant species is the Andean bromelilad, an endemic plant that takes up to 100 years to mature and a common diet for species that ...
