Influence of Bedload on Macroinvertebrate Community Composition

Abstract

Substrate and its movement across the streambed, or "bedload", can affect patterns of benthic macroinvertebrate distribution and abundance. This project investigated the influence of bedload and stream discharge on macroinvertebrate abundance and richness in a controlled, artificial stream. Special attention was given to functional feeding guilds, or groups of macroinvertebrates.
