Download or read book The Evolutionary Biology of the Bivalvia written by Elizabeth Harper and published by Geological Society of London. This book was released on 2000 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bivalves are key components of recent marine and freshwater ecosystems and have been so for most of the Phanerozoic. Their rich and long fossil record, combined with their abundance and diversity in modern seas, has made bivalves the ideal subject of palaeobiological and evolutionary studies. Despite this, however, topics such as the early evolution of the class, relationships between various taxa and the life habits of some key extinct forms have remained remarkably unclear. This volume integrates palaeontological and zoological approaches and sheds new light on the course of bivalve evolution.

Available in PDF, EPUB and Kindle. Book excerpt: Responding to the growing need for an aggressive yet conservative approach to evaluating mussel populations, Freshwater Bivalve Ecotoxicology provides a collective review of the techniques and approaches for assessing contaminant impact on freshwater ecosystems. The editors incorporate coverage of research topics and management issues from a cross-section of scientists in the field. They explore current advances in general monitoring of population responses to stressors, fundamental concepts of ecotoxicology specific to burrowing bivalves, and useful insights that offer direction and priority for resolving specific problems challenging protection and conservation efforts. This book lays the groundwork with discussions of topics such as impact assessment, toxicokinetics, biomarkers, and pollution tolerance. The authors then explore fundamental concepts surrounding responses measured in freshwater bivalves as a consequence of chemical exposures or accumulated contaminants in target organs or tissues. They highlight the difficulties encountered with the laboratory culture of these organisms for toxicity testing or other controlled experiments, and examine the use of surrogate test organisms to relate sensitivities of response and reduce pressure on already impacted fauna. The book also reviews innovative field research using in situ bivalve toxicity testing, discusses effects-oriented tissue contaminant assessment, and concludes with threefour specific laboratory or combined field/laboratory ecotoxicology studies. A summary of methods from more than 75 laboratory toxicity studies conducted with freshwater mussels, the book provides an overview of a standardized method for conducting water-only acute and chronic laboratory toxicity tests with glochidia juvenile freshwater mussels. It focuses on studies that report measured contaminant treatments, had robust experimental designs, including replication of control and contaminant treatments, and were published in the peer-reviewed literature. The resulting array of viewpoints provides a framework that can be used to establish priorities in the rehabilitation and management of freshwater ecosystems.

Download or read book The Freshwater Mussels of Ohio written by G. Thomas Watters and published by . This book was released on 2009 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early nineteenth century, a naturalist named Rafinesque stood on the banks of the Ohio River and began to describe the freshwater mussels he found there. Since that time, these animals have earned a place among the most imperiled animals in North America. Dozens of species have become extinct, and it is estimated that two-thirds of the remaining freshwater mussels face a similar fate. Yet, despite their importance, the mussels of Ohio remain a poorly documented and largely mysterious fauna. This book compiles existing research on Ohio's mussels, synthesizing works on genetics, biology, and systematics into one volume. Full-page color images depict shell variation, hinge detail, and beak sculpture. Full-page maps show the distribution of each species based upon the collections of numerous museums, with historical distributions dating from the 1800s. In addition to species accounts, the book has an introductory section that includes information on basic biology, human use, and conservation issues.--adapted from jacket.

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.

Book excerpt: Care-giving is an activity that has been practiced by all human societies. From the earliest societies through to the present, all humans have faced choices regarding how people in positions of dependency are to be treated. As such, care-giving, and the form it takes, is a central experience of being a human and one that is culturally mediated. Archaeology has tended to marginalise the study of care, and debates surrounding our ability to recognise it within the archaeological record have often remained implicit rather than a focus of discussion. These 12 papers examine the topic of care in past societies and specifically how we might recognise the provision of care in archaeological contexts and to open up an inter-disciplinary conversation, including historical, bioarchaeological, faunal and philosophical perspectives. The topic of ‘care’ is examined through three different strands: the provision of care throughout the life course, namely that provided to the youngest and oldest members of a society; care-giving and attitudes towards impairment and disability in prehistoric and historic contexts, and the role of animals as both recipients of care and as tools for its provision.

This book was released on 2015-11-06 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: “At the time it was first published in 1962, it framed such an urgent appeal to the American conscience that it actually prompted the creation of the Appalachian Regional Commission, an agency that has pumped millions of dollars into Appalachia. Caudill’s study begins in the violence of the Indian wars and ends in the economic despair of the 1950s and 1960s. Two hundred years ago, the Cumberland Plateau was a land of great promise. Its deep, twisting valleys contained rich bottomlands. The surrounding mountains were teeming with game and covered with valuable timber. The people who came into this land scratched out a living by farming, hunting, and making all the things they need-including whiskey. The quality of life in Appalachia declined during the Civil War and Appalachia remained “in a bad way” for the next century. By the 1940s, 50s, and 60s, Appalachia had become an island of poverty in a national sea of plenty and prosperity. Caudill’s book alerted the mainstream world to our problems and their causes. Since then the ARC has provided millions of dollars to strengthen the brick and mortar infrastructure of Appalachia and to help us recover from a century of economic problems that had greatly undermined our quality of life.”-Print ed.
