Definition of Term

equilibrium theory
(English) A theory of island biogeography maintaining that greater numbers of species are found on larger islands because the populations on smaller islands are more vulnerable to extinction. This theory can also be applied to terrestrial analogues such as forest patches in agricultural or suburban areas or nature reserves where it has become known as ‘insular ecology.’ (See also: ecosystem, habitat, conservation)
théorie de l'équilibre

Cette théorie peut être aussi appliquée aux analogues terrestres tel que des parcelles de forêt dans les régions agricoles ou suburbaines ou des parcs naturels où il est devenu connu comme écologie insulaire. (See also: ecosystem, habitat, conservation)
