About: Epigeal

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

Epigeal, epigean, epigeic and epigeous are biological terms describing an organism's activity above the soil surface. In botany, a seed is described as showing epigeal germination when the cotyledons of the germinating seed expand, throw off the seed shell and become photosynthetic above the ground. The opposite kind, where the cotyledons remain non-photosynthetic, inside the seed shell, and below ground, is hypogeal germination. An epigeal nest is a term used for a termite mound, the above ground nest of a colony of termites.

  • Epigeal, epigean, epigeic and epigeous are biological terms describing an organism's activity above the soil surface. In botany, a seed is described as showing epigeal germination when the cotyledons of the germinating seed expand, throw off the seed shell and become photosynthetic above the ground. The opposite kind, where the cotyledons remain non-photosynthetic, inside the seed shell, and below ground, is hypogeal germination. The terms epigean, epigeic or epigeous are used for organisms that crawl (epigean), creep like a vine (epigeal), or grow (epigeous) on the soil surface: they are also used more generally for animals that neither burrow nor swim nor fly. The opposite terms are hypogean, hypogeic and hypogeous. An epigeal nest is a term used for a termite mound, the above ground nest of a colony of termites. (en)
  • En écologie, zoologie et botanique, pour mieux les décrire, les milieux de vie sont parfois catégorisés en strates horizontales ; les espèces épigées y sont celles qui vivent sous la strate herbacée, en surface du sol ou d'un substrat naturel (sable, sédiments émergés, etc.).Ce qualificatif est aussi utilisé pour des espèces aquatiques (amphipodes épigés par exemple).
