Abstract

More than 1,100 samples of aquatic plants and associated invertebrates were collected in a prairie wetland. Sampling was done weekly throughout the duck brood rearing season. Linear regression revealed a 4 to 100 ratio of animal to plant biomass (R²=0.488). Comparatively high degrees of association were found between Ceratophyllum demersum and Gastropoda and between Lemna minor and most zooplankton groups. Significant sources of variation in invertebrate biomass were plant communities, date, plants, and community by date interaction. Depth and communities were not significant.
