An Evaluation Of Benthic Macroinvertebrate Community Structure And Sediment Toxicity In Lake Taylorville, Sanhita Datta
An Evaluation Of Benthic Macroinvertebrate Community Structure And Sediment Toxicity In Lake Taylorville, Sanhita Datta
Masters Theses
Sediments act as a "sink" for xenobiotics which can be accumulated by a variety of organisms and thereby enter the food chain contaminating fish, wildlife and humans. Although the chemical nature of these substances can be known by direct chemical analysis of the sediments, the significance of the contaminants and their bioavailability should be determined through bioassay techniques. A survey of the benthic macroinvertebrates of Lake Taylorville, a reservoir in central Illinois which is fed by two rivers that drain a primarily agricultural area, revealed a rather depauperate fauna. Subsequent studies were conducted in order to identify the underlying cause …

Lake Taylorville, an impoundment on the South Fork of the Sangamon River, is located just south of Taylorville in Christian County, Illinois. The tributaries of this reservoir drain primarily agricultural areas and contribute to degradation of the reservoir through excessive sediment and nutrient loading. A restoration project is underway which involves construction of sediment basins and dry dams. Analysis of the crustacean zooplankton community has formed an integral part of an intensive limnological investigation of the reservoir during the initial stages of the restoration effort. Seasonal variation in the composition, and density of the major groups was observed. Rotifers (Brachionus …
