Download or read book Fresh Water Mussels Mollusca Bivalvia Unionidae of the Upper Mississippi River Observations at Selected Sites Within the 9 Foot Channel Navigation Project on Behalf of the U S Army written by Samuel L. H. Fuller and published by . This book was released on 1978 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: A survey of freshwater mussels of the Upper Mississippi River drainage was conducted during the summer and autumn of 1977. Over 8,000 living specimens were gathered and examined during surveillance of more than 40 actual and/or potential dredging sites in the Minnesota and St. Croix Rivers and in almost 20 Upper Mississippi River pools. Dredging and associated activities to maintain the 9-foot navigation channel has caused local mortality of mussels, including endangered species. There are other factors having far greater adverse impact, including wastes from the cities of Minneapolis and St. Paul, agricultural runoff, impoundment of the Upper Mississippi River and encroachment by Corbicula fluminea, the Asiatic Clam. The outlook for a continuing ecosystematic and commercial mussel resource appear to be good. Even certain endangered species (e.g. Lampsilis higginsi) are likely to survive if appropriate measures are taken.

H. Fuller and published by . This book was released on 1980 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objectives of the study were to characterize the present mussel fauna, to compare it to the fauna existing before the 9-foot Navigation Channel Project, and to determine the influence(s) upon mussels by practices of the District's Operations and Maintenance (O & M) activities. The study area was the main channel and main channel borders of the UMR itself from Head of Navigation at river mile (RM) 857.8 in the Twin Cities, Minnesota, to Locks and Dam 10 at Guttenberg, Iowa (RM 615.1), and the lowermost (Corps-maintained) reaches of the black (at La Crosse, Wisconsin), Minnesota, and St. Croix rivers. More than 100 formal Sites were thoroughly surveyed (usually by brailing), and about a dozen locations were investigated cursority. Over 10,000 living mussels were collected and examined, including a few of the Endangered Lampsilis higginsi.

Download or read book North American Freshwater Mussels written by Wendell R. Haag and published by Cambridge University Press. This book was released on 2012-08-27 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: This well-illustrated book highlights freshwater mussels' fabulous diversity, amazing array of often bizarre ecological adaptations and their dire conservation plight. Summarizing and synthesizing historical and contemporary information as well as original research and analysis, the book describes the diverse array of mussel life history strategies and builds a cohesive narrative culminating in the development of explicit frameworks to explain pervasive patterns in mussel ecology. The fascinating and colorful role of mussels in human society is also described in detail, including the little-known pearl button industry of the early 1900s and the wild and often violent shell harvest of the 1990s. The final chapter details humans' efforts to save these fascinating animals and gives a prognosis for the future of the North American fauna. The book provides the first comprehensive review of mussel ecology and conservation for scientists, natural resource professionals, students and natural history enthusiasts.

Download or read book Ecology and Evolution of the Freshwater Mussels Unionoida written by G. Bauer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: All those who think that bivalves are boring are in the best company. Karl von Frisch is reported to have turned the pages more quickly in texts where bivalves were treated because, according to him, they literally lack any behaviour. The fact that they can filtrate huge amounts of water, burrow into the sedi ment, actively swim, drill holes into rocks and boats or detect shadows with the aid of pretty blue eyes located on the rim of their mantle obviously left v. Frisch unimpressed. Why, then, a book on the large freshwater mussels (Naiads or Unionoida), which on first sight are much less spectacular than the marine ones? The main reason is that they are keepers of secrets which they reveal only on close and careful inspection. This is not only true for the pearls some species produce and which over centuries have contributed to the treasures of bishops and kings, but particularly for their ecology: their life cycles are linked with those of fishes, some can occur in incredible densities and some can live for more than 100 years. Thus, the presence or absence of naiads in a lake or stream has manifold implications.

This book was released on 1997 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A survey to assess community characteristics, density, population demography of dominant species, and the presence of rare or endangered species of mussels (Family: Unionidae) was conducted in selected reaches of the Quiver River and Bogue Phalia, Mississippi, in 1994 and 1995 for the U.S. Army Engineer District, Vicksburg. Results are being used to assess the economic value of mussels in the project area and to determine the environmental effects of proposed maintenance dredging. The project area included a section of the Quiver River between its confluence with the Big Sunflower River immediately north of Highway 82 in Sunflower County to the Leflore-Tallahatchie county line. In the Bogue Phalia, the study area consisted of a reach between Highway 82 and Rosedale, west-central Bolivar County. Twenty-two species of native freshwater mussels were collected in the Quiver River; 26 sites were sampled using qualitative methods, and a total of 2,238 mussels were collected. The dominant mussel was Amblema p. plicata, which comprised over 67 percent of the mussel fauna. Plectomerus dombeyanus comprised 20 percent of the mussels. Overall species diversity (0.67 to 0.90) was low, mainly because of the dominance of A. p. plicata. Evidence of recent recruitment was low; approximately 7 percent of the species and 0.15 percent of the individuals collected were less than 30 mm total shell length. Overall mean density ranged from less than 8.6 individuals/square meter at River Mile (RM) 6.4 to 92.3 individuals/square meter at RM 19.7.
