The study of genetic differences between related species, and populations of a species, in relation to the environment. Hence genecoˈlogic, genecoˈlogical adjs.
1923G. Turesson in Hereditas IV. 172 It seems appropriate for several reasons to denote this study of species-ecology by the term genecology..as distinct from the ecology of the individual organism, for which the old term autecology seems to be the adequate expression. 1928B. D. Jackson Gloss. Bot. Terms (ed. 4) 439/2 Genecological. 1947R. F. Daubenmire Plants & Environment x. 366 (heading) The genecologic classification. 1963Davis & Heywood Princ. Angiosperm Taxon. xii. 398 Genecological differentiation has been found to be especially common in trees. Ibid. 401 The basis of genecology..is the observation that this intra-specific variability can be demonstrated to be of genetic origin and is not randomly dispersed throughout the species range, but is distributed in such a way that neighbouring plants tend to resemble one another. |
