Alpine tundra in the Venezuelan Andes. Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges ...
Páramo in Colombia. Páramo (Spanish pronunciation:) may refer to a variety of alpine tundra ecosystems located in the Andes Mountain Range, South America. Some ecologists describe the páramo broadly as "all high, tropical, montane vegetation above the continuous timberline". [1]
Alpine plants are plants that grow in an alpine climate, which occurs at high elevation and above the tree line. There are many different plant species and taxa that grow as a plant community in these alpine tundra. [1] These include perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. [2]
Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by plants that grow close to the ground, including perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. [28] The flora is adapted to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet ...
The Köppen climate classification is "ETH": Alpine tundra, with no month with an average temperature in excess of 10 °C (50 °F). [4] [5] Where the Northern Andean páramo is generally humid throughout the year with moisture delivered in the form of rain, clouds and fog as air masses are lifted up over the mountains, the Cordillera de Merida páramo is similar to the Costa Rican páramo and ...
Alpine level: [7] [20] The zone that stretches between the tree line and snowline. This zone is further broken down into Sub-Nival and Treeless Alpine (in the tropics-Tierra fria; low-alpine) Sub-nival: [20] The highest zone that vegetation typically exists. This area is shaped by the frequent frosts that restrict extensive plant colonization.
Alpine flora near Cascade Pass. Alpine grasslands and tundra lie above the tree line, in a world of intense radiation, wind, cold, snow, and ice. As a consequence, alpine vegetation is close to the ground and consists mainly of perennial grasses, sedges, and forbs. Annual plants are rare in this ecosystem and usually are only a few inches tall ...
Alpine Tibet hosts a limited diversity of animal species, among which snakes are common. There are only two endemic reptiles and ten endemic amphibians in the Tibetan highlands. [ 74 ] Gloydius himalayanus is perhaps the geographically highest living snake in the world, living at as high as 4,900 m (16,100 ft) in the Himalayas. [ 80 ]
