Highly fertile soil means richer plant and animal life. Altitudinal zonation in mountainous regions describes the natural layering of ecosystems that occurs at distinct altitudes due to varying environmental conditions.Temperature, humidity, soil composition, and solar radiation are important factors in determining altitudinal zones, which consequently support different vegetation and animal species. - Pertaining to the vertical elevation of an object above a given level. Repräsentationen HTML RDF/XML RDF/Turtle RDF/NTriples. Ha permanent sle plots are discussed. The general pattern of altitudinal zonation shows an increase in spe­ cies richness from the headwaters (< 2000 m : 58 spp.) First, altitudinal zonation occurs in hilly regions. The natural layering of ecosystems along altitude in mountain regions is well known (e.g. This study examined arthropod community patterns over an altitudinal ecoregional zonation that extended through three ecoregions (Yungas, Monte de Sierras y Bolsones, and Puna) and two ecotones (Yungas-Monte and Prepuna) of Northwestern Argentina (altitudinal range of 2,500 m), and evaluated the abiotic and biotic factors and the geographical distance that could influence them. toward the middle reaches (1000-1600 m : 121 spp. from them to the dry ones. 1991). Abi-Saleh Bernadette. Altitudinal zonation Altitudinal zonation in mountainous regions describes the natural layering of ecosystems that occurs at distinct altitudes due to varying environmental conditions. With increased altitude conditions usually become cooler and damper, so that the vegetation of mountains of considerable elevation shows a corresponding zonation. Most of the huge coniferous and deciduous trees grow there. Within the tundra biome a latitudinal zonation of communities is realized: High Arctic Tundra: essentially confined to the islands of the Arctic Ocean and … ). Zonation was first defined as a fundamental law of differentiation of major natural complexes by … The general effect of elevation depends on atmospheric physics. Tibetan rangelands. Fauna is similarly distributed, with distinct altitudinal zonation present. Altitudinal zonation definitions. altitudinal. Altitudinal zonation (or elevational zonation [1]) in mountainous regions describes the natural layering of ecosystems that occurs at distinct elevations due to varying environmental conditions. Most vegetation relies on high temperature to thrive. As such, precipitation is most important in determining zonation. By using our services, you agree to our use of cookies. Science and technology Altitudinal zonation Altitudinal zonation in mountainous regions describes the natural layering of ecosystems that occurs at distinct altitudes due to varying environmental conditions. Forests, grasslands, cropland and thereby helped. ; Fauna is similarly distributed, with distinct altitudinal zonation present. As such, most flora and fauna is located there as opposed to other regions. Start studying Altitudinal Zonation - Chapter 13. ; The generally strong dependency on elevation is known as altitudinal zonation: the average temperature of a location decreases as the elevation increases. "' Temperatures that are too high or two low support very few species of plants. Altitudinal zonation. Altitudinal zonation (or elevational zonation) in mountainous regions describes the natural layering of ecosystems that occurs at distinct elevations due to varying environmental conditions. Higher regions of the mountain experience very low temperatures. Zonation of thermal conditions was recognized as early as classical times. Daubenmire, 1943 , Hagvar, 2005 , Hemp, 2006 ) but zonation also occurs in freshwater (e.g. Altitudinal zonation refers to the distinct changes in ecosystems due to changes in altitude or elevation. Altitudinal Zonation Applied primarily in Latin America, this term refers to the differentiation of distinct environmental regions characterized by specialized agricultural production, based on elevation.

Start studying Geography Altitudinal Zonation. The weaker ones can either adapt or migrate. The type of soil in a zone will obviously affect the type and size of vegetation living there. The altitudinal zonation of tropical rain forests has been the subject of numerous studies and many classifications, with varying terminologies, have been proposed. Zonation occurs in the ocean zone called the intertidal. Altitudinal Zonation Applied primarily in Latin America, this term refers to the differentiation of distinct environmental regions characterized by specialized agricultural production, based on elevation. zones. Nutrients come from minerals in rocks and decaying vegetation or animals. Today, altitudinal zonation represents a core concept in mountain research. What are the levels of a mountain? Learn vocabulary, terms, and more with flashcards, games, and other study tools. This means that the physical location of the mountain should be taken into account while attempting to determine zonation.
