ecophenen.

Brit.

/ˈiːkəʊfiːn/,

/ˈɛkəʊfiːn/, U.S.

/ˈɛkoʊˌfin/,

/ˈikoʊˌfin/

Origin: Formed within English, by compounding. Etymons: eco- comb. form, phenotype n.

Etymology: < eco- comb. form + -phene (representing phen- in phenotype n.). Compare earlier ecotype n. and later ecophenotype n.

Ecology.

The range of phenotypes produced by a single genotype, as found in populations of an organism across its natural range of habitats. Also: any of the range of such phenotypes specific to a given habitat (cf. ecophenotype n., ecotype n.).

1922 G. Turesson in Hereditas 3 347 The term ecophene is proposed to cover each of the reaction-types of the ecotypes arising through the modificatory influences of the combinations of extreme habitat factors given in nature.

1957 Encycl. Brit. XXI. 177/2 Ecophenes are illustrated by climatic modifications at the tree line, by shade types of plants that normally range through a variety of light conditions, and by temperature influences on growth at different latitudes.

1968 R. F. Daubenmire Plant Communities i. 33 Whether these variations represent ecotypes or ecophenes, the habitat type is the best indicator of the extent of each type of variance.

2001 Jrnl. Ecol. 89 60 Puccinella species were combined, because Puccinella phryganodes..and Puccinella nutkaensis..may be ecophenes.
