Book Synopsis Macrobenthic Survey of Navigation Pool No. 8 of the Upper Mississippi River, with Special Reference to Ecological Relationships by : Catherine Ann Elstad
Download or read book Macrobenthic Survey of Navigation Pool No. 8 of the Upper Mississippi River, with Special Reference to Ecological Relationships written by Catherine Ann Elstad and published by . This book was released on 1977 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: The macrobenthic fauna of Navigation Pool No. 8 of the Upper Mississippi River was inventoried and correlated with the average physical-chemical conditions encountered in the pool. Forty-one sampling areas, numbered in order of increasing current velocity, were delineated on the basis of characteristic chemical and physical properties during the summer of 1975. A trend toward decreasing eutrophy occurred from area 1 to area 41. Benthos samples were collected twice during the summer in each of the study areas. One hundred forty-four taxa were found in the 616 Ponar-dredge collections. Over half of the collected taxa were insect nymphs and larvae. A total of 90,693 representatives of the Phyla Platyhelminthes, Nematoda, Annelida, Arthropoda, and Mollusca were counted, weighed, and identified. Oligochaetes were by far the most ubiquitous and dominant macroinvertebrates. Greatest oligochaete densities were respectively recorded during Sampling Periods I and II in areas 3 (17,306.10/m2) and 18 (16,609.98/m2) and in areas 1 (10,302.11/m2) and 18 (10,894.18/m2). The qualitative and the quantitative compositions of the benthic communities varied among the 41 study areas. Habitat preferences of particular benthic forms were reflected in the distributional relationships between the macroinvertebrates and the physical-chemical conditions. Benthic production, in terms of the total wet weight/m2 and the mean number of macroinvertebrates/m2 in each area, was generally greater in the more eutrophic areas. The more eutrophic areas supported fewer taxa. These taxa generally consisted of pollution-tolerant organisms, such as oligochaetes and certain chironomids, which were capable of burrowing into the depositional-type substrates. More taxa and greater numbers of gill breathers and filter feeders, such as caddisflies, mayflies, stoneflies, and dipterans, were collected from the less eutrophic areas.
Book Synopsis Spatial Patterns of Macroinvertebrates on the Upper Mississippi River System by : Jennifer S. Sauer
Download or read book Spatial Patterns of Macroinvertebrates on the Upper Mississippi River System written by Jennifer S. Sauer and published by . This book was released on 1998 with total page 2 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most widespread annual collections of benthic (bottom dwelling) macroinvertebrates in the Upper Mississippi River System (UMRS) are now being made as part of the Long Term Resource Monitoring Program (LTRMP). Long-term monitoring is necessary to better understand the conditions needed to support viable macroinvertebrate populations at levels adequate to sustain native fish and migrating waterfowl. In 1992, the long-term monitoring of select taxa began in Pools 4, 8, 13, 26 and the Open River Reach of the Upper Mississippi River and in La Grange Pool of the Illinois River. Mayflies (Ephemeroptera), fingernail clams (Sphaeriidae), and Asiatic clams (Corbicula sp.) were first selected for sampling, followed by midges (Chironomidae) in 1993, and zebra mussels (Dreissenapolymorpha) in 1995.

This book was released on 1972 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1980 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: A diel periodicity study of drifting benthos in the lower Mississippi River at mile 529 resulted in the collection of 5090 macroinvertebrates consisting of 80 taxa. Samples collected with 505 micrometer mesh, 0.5-m (mouth diameter) plankton nets at midnight (0100 hr), dawn (0600 hr), noon (1200 hr), afternoon (1600 hr), and dusk (2100 hr) on 27-28 June 1978, had an average total drift density over all sampling times of 140 organisms/100 cubic meters of water filtered. Total drift density did not fluctuate markedly over the five sampling times, except that concentrations were significantly lower (P
