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]
Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline.
Consisting of the arctic, alpine, and Antarctic regions, and stemming from the Samer language, tundra literally means a "high and dry place". The arctic tundra has an exceptionally short growing period, minimal sunlight, and limited resources, creating a brutal environment for plants and animals.
Documented Nahuatl words in the Spanish language (mostly as spoken in Mexico and Mesoamerica), also called Nahuatlismos include an extensive list of words that represent (i) animals, (ii) plants, fruit and vegetables, (iii) foods and beverages, and (iv) domestic appliances. Many of these words end with the absolutive suffix "-tl" in Nahuatl.
The term tundra comes through Russian тундра from the Kildin Sami word tūndâr "uplands," "treeless mountain tract." [15] There are three types of tundra: Arctic tundra, [16] alpine tundra, [16] and Antarctic tundra [17] In tundra, the vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow ...
Temperature, humidity, soil composition, and solar radiation are important factors in determining altitudinal zones, which consequently support different vegetation and animal species. [ 2 ] [ 3 ] Altitudinal zonation was first hypothesized by geographer Alexander von Humboldt who noticed that temperature drops with increasing elevation. [ 4 ]
The coastal regions, up to an altitude of about 50 m, are generally covered with low herbaceous vegetation, and are classified as tundra. Higher up, rocky ground dominates and the vegetation is rarer, limited to scattered tufts and mosses and lichens. There are no trees or shrubs on the islands. This was not always the case, however.
The Canadian Arctic tundra is a biogeographic designation for Northern Canada's terrain generally lying north of the tree line or boreal forest, [2] [3] [4] that corresponds with the Scandinavian Alpine tundra to the east and the Siberian Arctic tundra to the west inside the circumpolar tundra belt of the Northern Hemisphere.
