faciation Ecol.|feɪsɪˈeɪʃən|
[f. L. faciēs + -ation.]
A community containing more than one of the dominant species in an association (often related to climatic or geographic differences in the area of the association).
1920F. C. Clements Plant Indicators 276 The grouping of consociations within the association is typical of all climaxes, and seems to warrant a special term... It has seemed desirable to definitize the term facies for seral groupings and to make a new word, faciation, for climax groupings... The two terms conform to the mutual relation seen in associes and association, consocies and consociation. 1938,1960[see facies 2 c]. 1952P. W. Richards Tropical Rain Forest xv. 319 Four ‘faciations’ of Evergreen Seasonal forest are recognized; more or less the same species occur in all of them but in different proportions. |
