Aquatic Plant Control Research Program: The Habitat Value of Aquatic Macrophytes for Macroinvertebrates.

摘要

This document summarizes and discusses recent studies on the value of submersed aquatic macrophytes for macroinvertebrates. Discussion on the effects of macrophytes on benthic invertebrates is followed by sections on the colonization of macroinvertebrates on Potamogeton nodosus and Ceratophyllum demersum. The next parts describe a study on the effects of macrophytes on distribution of zooplankton, the effects of C. demersum structure on macroinvertebrate colonization. The report concludes with a general summary and literature review of the effects of plants on biotic and abiotic factors in aquatic systems. The majority of these studies took place in Eau Galle Reservoir, Wisconsin, except for the final study of C. demersum, which was conducted in a borrow pit lake in Louisiana. Appendix A presents summary data on macroinvertebrates associated with aquatic macrophytes. Keywords: Aquatic plants; Invertebrates underwater habitats; Freshwater ecosystems. (EDC)
