✦ Synopsis
In the littoral zone of the St-Lawrence River (Quebec, Canada), benthic and phytophilous macroinvertebrates were studied in order to find and to explain relationships between structure of these animal communities and abiotic (substrate, water depth, current velocity) or biotic (marophytes species) factors . Benthos was sampled at 16 sites in spring, when there was no macrophytic vegetation, and in summer . Phytomacrofauna was sampled at 30 sites in summer . The data were analyzed using simple and partial correlations, stepwise regression, reciprocal averaging and canonical correlation analysis .
