Spatial Distribution of Mussels at a Bed in the Lower Ohio River Near Olmsted,Illinois

摘要

The study herein was conducted by the U.S. Army Engineer Waterways ExperimentStation (WES) in 1993 and 1994 for the U.S. Army Engineer District, Louisville, Louisville, KY. The purpose was to map the distribution of native and nonindigenous mussels in a prominent mussel bed in the lower Ohio River near Olmsted, IL, with special emphasis on delineating the boundaries of the native mussel bed. Data on density, size demography of dominant populations, species diversity, and community composition will be used to analyze the environmental effects of construction and operation of Olmsted Locks and Dam Project.
