Abstract
Principal component analysis ordinates temporal changes in species composition in samples collected regularly from March 1970 throughout August 1973. The results indicate two compositionally stable periods (winter and summer) separated by spring and autumn transition periods where composition changes rapidly. Each transition appears distinct; spring compositional changes do not simply mirror autumn changes. Some seasonal information is lost when samples for both years are simultaneously considered. Nine physico-chemical factors are examined as potential correlates of compositional change, individually, and through an environmental ordination.This publication has 0 references indexed in Scilit:
