Book Description
The general objectives of this study have been to provide basic knowledge about the biology of a large river by determining the quality and quantity of the macroinvertebrates benthic populations of the Mississippi River in the Monticello, Wright County, Minnesota, region; and secondly to provide pre-operational data on the macroinvertebrates in the river before the Monticello Nuclear Power Plant begins operation. Specifically, a five-mile stretch of the river was studied with the goal of evaluating transverse and longitudinal distributions of the macroinvertebrates, their life histories, and the seasonal dynamics of the dominant genera. Various physical and chemical factors which influence the macroinvertebrate populations were also measured. Finally, since very few investigations have dealt with conditions existing in streams and rivers during the winter season, special attention was given to determination of the ecological changes occurring during that time of year, despite extremely difficult operational conditions.

ASSESSMENT OF IMPLANTED SUBSTRATE SAMPLERS FOR MACROINVERTEBRATES INHABITING STONE DIKES OF THE LOWER MISSISSIPPI RIVER.

Book Description
The aquatic macroinvertebrate assemblage of a dike in the Lower Mississippi River was evaluated by implanting substrate basket samplers into the structure. The resulting data indicated that a diverse (38 taxa) and productive (average density = 101,968.4 organisms/sq. m assemblage was present, and was characterized by net-spinning caddisflies, tube-building chironomids, clinging mayflies, and isopods. A comparison of the surface stones of the basket samplers with adjacent surface stones of the dike indicated that the implanted substrates provided representative estimates of both the composition and structure of the macroinvertebrate assemblage. These data also indicated significant macroinvertebrate activity below the surface substrate of the dike. Differences in habitat conditions among dike positions (downstream, top, upstream) were the major contributors to overall sample variability. Thus, stratified random sampling based on dike position is recommended for future comparative studies. (Author).
