Benthic Macroinvertebrates of Selected Aquatic Habitats of the Lower Mississippi River.

Abstract

This report describes benthic macroinvertebrate composition and distribution in four aquatic habitat types within a 60-mile reach of the Lower Mississippi River. The macroinvertebrate biotas of the four habitat types, dike fields (three), a natural band, a secondary channel, and an abandoned channel, were studied over one high flow (flood stage), two moderate, and two low flow periods between April 1979 and September 1980. The biotas present in the natural bank, secondary channel, and abandoned channel showed only minor changes in composition over the various flow regimes. Unlike the other habitats, the dike fields showed large changes in biotic composition, which correlated with changes in river stage and resultant alterations in current and substrate.
