Abstract

This study synthesizes the results from ten years (1978–1988) of research in lotic environments of the middle Parana River. We elucidate the important environmental factors that determine differences in quality and structure of the benthos among the main channel, secondary channels and tributaries, and we determine species or descriptive associations of the different types of environment.
