QUE SIGNIFIE ECOTYPE EN ANGLAIS
Ecotype
Dans l'écologie évolutive, un écotype, parfois appelé écospace, décrit une variété géographique, une population ou une race génétiquement distinctes dans les espèces, adapté à des conditions environnementales spécifiques. Généralement, les écotypes présentent des différences phénotypiques découlant de l'hétérogénéité de l'environnement et sont capables de se reproduire avec d'autres écosystèmes géographiquement adjacents sans perte de fertilité ou de vigueur.

La définition de l'écotype dans le dictionnaire est un groupe d'organismes au sein d'une espèce qui est adapté à des conditions environnementales particulières et présente donc des différences comportementales, structurelles ou physiologiques par rapport aux autres membres de l'espèce.
