Abundance, Biomass, and Diversity of Aquatic Invertebrates in Level Ditches and Adjacent Natural Emergent Marsh in an Eastern South Dakota Wetland

The aquatic invertebrate communities of level ditches and adjacent natural emergent marsh in a South Dakota prairie wetland were sampled during the summer of 1982. Collections were made in both the water column and the bottom substrates. Forty-five taxa were collected. Analysis of variance indicated that a significantly greater mean number of taxa and a larger mean number of all macroinvertebrates were present in level ditches than in the natural emergent marsh. No differences were detected for mean biomass of all macroinvertebrate taxa collectively. Several taxa had a greater mean number and biomass in the level ditches than in the natural emergent marsh. Discussion of the composition of duck diets during the breeding and brood rearing seasons revealed that the level ditches provided an abundance and diversity of the aquatic invertebrates consumed by ducks.
