Book Long Term Resource Monitoring Program Annual Status Report 1999

Download or read book Long Term Resource Monitoring Program Annual Status Report 1999 written by Jennifer S. Sauer and published by . This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1992, macroinvertebrate sampling was initiated in Pools 4, 8, 13, 26, and the Open River reach of the Mississippi River, and La Orange Pool of the Illinois River as part of the Long Term Resource Monitoring Program. Long-term monitoring is needed to detect population trends and local changes in aquatic ecosystems. Mayflies (Ephemeridae), fingernail clams (Sphaeriidae), and the exotic Asiatic clam (Corbicula) were selected for monitoring. Midges (Chironomidae) were added to the sampling design in 1993 and zebra mussels (Dreissena polymorpha) in 1995. Mayflies, fingernail clams, and midges, members of the soft-substrate community, were chosen because they play an important ecological role in the Upper Mississippi River System. Sampling was based on a stratified random design and was conducted at about 125 sites per study area. Mean densities of taxa were weighted by strata for extrapolation purposes. Pool 8 had the highest estimated mean densities of mayflies and fingernail clams (215 and 505 per m2, respectively). Pool 13 had the highest estimated mean number of midges (234 per m2). Overall, the impounded areas (including Lake Pepin) and the contiguous backwaters tended to support the highest mean densities of mayflies, fingernail clams, and midges. Substrates with predominantly a silt clay constituent supported the highest mean densities of mayflies, fingernail clams, and midges.
