Résumé

Reformulates the community-unit and individualistic concepts of plant communities as hypotheses concerning the distribution of species' boundaries along a gradient. These hypotheses are tested by an analysis of deviance on data derived from a direct-gradient analysis of a freshwater marsh plant community in Breckenridge, Quebec. Boundaries are clustered at certain intervals along the gradient, contradicting the individualistic hypothesis. Upper boundaries are not consistently clustered at the same intervals as lower boundaries, contradicting the community-unit hypothesis. The way out of the community-unit vs. individualistic community debate is to deny the dichotomy and to consider multiple working hypotheses of community structure. -from Authors
