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. Temperature , humidity , soil composition, and solar radiation are important factors in determining altitudinal zones, which consequently support ...
Altitudinal migration is a short-distance animal migration from lower altitudes to higher altitudes and back. [1] [2] Altitudinal migrants change their elevation with the seasons making this form of animal migration seasonal. [3] [4] Altitudinal migration can be most commonly observed in species inhabiting temperate or tropical ecosystems. [3]
Altitudinal variation in the Andes. Sea level Estimated 22 - 24°C (75°F), but the cold Humboldt Current generates fog on the coast side; Tierra caliente (Hot land, tropical) up to 2,500 ft (about 750 m - 1,000 m). Crops: Cacao, Banana, Sugarcane, Manioc, Sweet Potatoes, Yams.
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
The first recorded observation of the elevational diversity gradient was by Carl Linnaeus in his treatise On the growth of the habitable Earth.In this document, Linnaeus based his predictions on flood geology, assuming most of the world was at one point inundated, leaving only the highest elevations available for terrestrial life.
The exact definition and reference datum varies according to the context (e.g., aviation, geometry, geographical survey, sport, or atmospheric pressure). Although the term altitude is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage.
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time.Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area. [1]
Narrower ranges in the tropics would facilitate more species to coexist. He later extended the rule to altitudinal gradients, claiming that altitudinal ranges are greatest at greater latitudes (Stevens 1992 [4]), and to depth gradients in the oceans (Stevens 1996 [5]). The rule has been the focus of intense discussion and given much impetus to ...
