Chilton, E. W., and Ohio State Univ., Columbus USA, 1987, Macroinvertebrate communities associated with selected macrophytes in Lake Onalaska: Effects of plant type, predation, and selective feeding: Dissertation Abstracts International B Sciences and Engineering, v. 47, no. 7, 177 p. Abstract: To determine the effects of plant species on aquatic invertebrate assemblages, differences among macroinvertebrate communities associated with three aquatic macrophytes: Vallisneria americana, Myriophyllum spicatum , and Ceratophyllum demersum were investigated. Samples of each macrophyte were collected, from Lake Onalaska, Wisconsin. The invertebrate communities associated with each plant were described and comparisons made among plants. Quantitative differences occurred among plants. Vallisneria supported the smallest invertebrate community, Ceratophyllum supported the largest community, and Myriophyllum supported an invertebrate community that was of intermediate size when compared to those of the other plants. Plant type and predation pressure play an important role in the determination on invertebrate community size and composition.
