Definition of ecotype in US English:



Botany Zoology
  • A distinct form or race of a plant or animal species occupying a particular habitat.

    • ‘Geographically isolated populations often have evolved into distinct ecotypes that differ in morphological, life history, or behavioral traits.’
    • ‘Further, annual and perennial forms can exist as ecotypes of the same species.’
    • ‘It is not known how changes have occurred in the evolution of different species or of ecotypes adapted to different conditions, nor in the selection breeding of different varieties.’
    • ‘The morphological differences are genetically determined and it is thus possible that the turlough population is a distinct ecotype adapted to this unusual habitat.’
    • ‘The development of hardiness is so crucial for survival that many boreal and temperate zone woody species have evolved latitudinal ecotypes, differing in their timing of growth cessation and cold acclimation.’
