About: Minerotrophic

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Minerotrophic refers to environments that receive nutrients primarily through groundwater that flows through mineral-rich soils or rock, or surface water flowing over land. Minerotrophic, “minerogenous”, and “geogenous” are now often used interchangeably, although the latter two terms refer primarily to hydrological systems, while the former refers to nutrient dynamics. The hydrologic process behind minerotrophic wetlands results in water that has acquired dissolved chemicals which raise the nutrient levels and reduce the acidity. This in turn affects vegetation assemblages and diversity in the wetland in question. If dissolved chemicals include chemical bases such as calcium or magnesium ions, the water is referred to as base-rich and is neutral or alkaline. In contrast to minerotrophic e

  • Minerotrophic refers to environments that receive nutrients primarily through groundwater that flows through mineral-rich soils or rock, or surface water flowing over land. Minerotrophic, “minerogenous”, and “geogenous” are now often used interchangeably, although the latter two terms refer primarily to hydrological systems, while the former refers to nutrient dynamics. The hydrologic process behind minerotrophic wetlands results in water that has acquired dissolved chemicals which raise the nutrient levels and reduce the acidity. This in turn affects vegetation assemblages and diversity in the wetland in question. If dissolved chemicals include chemical bases such as calcium or magnesium ions, the water is referred to as base-rich and is neutral or alkaline. In contrast to minerotrophic environments, ombrotrophic environments get their water mainly from precipitation, and so are very low in nutrients and more acidic. Of the various wetland types, fens and rich fens are often minerotrophic while poor fens and bogs are often ombrotrophic. Marshes and swamps may also be fed through groundwater sources to a degree.

  • La minérotrophie est un niveau trophique qui fait intervenir différents processus de météorisation et de pédogenèse qui rendent disponibles différentes ressources (air, eau, sol) et éléments minéraux pour les niveaux trophiques suivant, la phytotrophie (végétaux qui utilisent les minéraux pour la photosynthèse) et la zootrophie (animaux qui se nourrissent de végétaux — phytophagie — ou d'autres animaux — carnivorie ou prédation — stricto sensu). En biogéographie, la minérotrophie ou géotrophie désigne l'alimentation de milieux 'minérotrophes en eau par des apports qui proviennent principalement des eaux de ruissellement et des remontées de nappe phréatique. Pour les sols et la végétation, ces approvisionnement sont les ruisseaux ou des sources. Cette eau a traversé des roches ou d’autres minéraux, acquérant souvent des produits chimiques dissous qui augmentent les niveaux de nutriments et réduisent l’acidité. Si ces produits chimiques incluent des bases chimiques telles que des ions calcium ou magnésium, l'eau est dite ou neutre ou alcaline. Contrairement aux environnements minérotrophes, les environnements ombrotrophes tirent leur eau principalement des précipitations, ils sont donc très pauvres en éléments nutritifs et plus acides.
