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 2006-10-11 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the multidisciplinary results of an extensive underwater excavation in north Florida. This yielded the most complete results of interactions between early Paleoindians and late Pleistocene megafauna, in a rich environmental context in eastern North America. The data provides fundamental insights into "the Peopling of the Americas" and "The Extinction of the Megafauna". An excellent color photo section expresses the uniqueness of this project.

Download or read book Trace Fossils written by William Miller III and published by Elsevier. This book was released on 2011-10-13 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book serves as an up-to-date introduction, as well as overview to modern trace fossil research and covers nearly all of the essential aspects of modern ichnology. Divided into three section, Trace Fossils covers the historical background and concepts of ichnology, on-going research problems, and indications about the possible future growth of the discipline and potential connections to other fields. This work is intended for a broad audience of geological and biological scientists. Workers new to the field could get a sense of the main concepts of ichnology and a clear idea of how trace fossil research is conducted. Scientists in related disciplines could find potential uses for trace fossils in their fields. And, established workers could use the book to check on the progress of their particular brand of ichnology. By design, there is something here for novice and veteran, insider and outsider, and for the biologically-oriented workers and for the sedimentary geologists.* Presents a review of the state of ichnology at the beginning of the 21st Century* Summarizes the basic concepts and methods of modern trace fossil research* Discusses crucial background information about the history of trace fossil research, the main concepts of ichnology, examples of current problems and future directions, and the potential connections to other disciplines within both biology and geology

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.
