Available in PDF, EPUB and Kindle. Book excerpt: "The Freshwater Mussels of Tennessee . . . is indispensable to anyone, anywhere, working on this group. Parmalee and Bogan have written a work that sets the standard for future regional guides."--G. Thomas Watters, Ohio Biological Survey "The Freshwater Mussels of Tennessee documents a tremendously diverse and unique mussel fauna that is rapidly being destroyed by modern development. Parmalee and Bogan set a new standard for state mussel surveys in their authoritative, thorough, and and highly readable account. The book will be of interest to biologists and conservationists worldwide and will appeal to anyone who cares about the preservation of natural resources in the southeastern United States."--Robert E. Warren, Illinois State Museum With more than 150 species and subspecies recorded in the state, Tennessee has one of the most diverse freshwater mussel faunas in North America. Valuable as indicators of water quality, these mollusks have themselves become threatened as development encroaches on habitat--twenty-three are currently listed as endangered species and at least twelve have become extinct. This is the first book for Tennessee to deal with this biologically and commercially significant group of mollusks. Its authors have been studying and writing about the mussels of Tennessee for more than twenty years and have undertaken a systematic organization of a large and complex body of information to bring order to a difficult field. The book traces the long history of human exploitation of mussels, from aboriginal food gathering to the growth of the cultured pearl industry. It provides an interpretive context for its exhaustive species accounts with background material on biology, distribution, economic utilization, taxonomy, and conservation issues. The authors also review the life cycle of the mussel and describe its many remarkable traits, such as its shell formation and the strategies it employs during the larval stage in parasitizing fish. The species accounts comprise 128 members of Family Unionidae--from pigtoes and pocketbooks to lilliputs and spikes--plus four additional species. The authors cover classification and synonymy, range and distribution, life history and ecology, and survival status. Particular attention is paid to shell description and structure to assist the reader in identification. Each species account includes a distribution map and color photos of two specimens. The Freshwater Mussels of Tennessee is a major reference that encompasses historical and modern mussel collections and draws on conservation studies that span two centuries. It will stand as an authoritative guide to understanding Tennessee mollusks and as a benchmark in the study of these species worldwide. The Authors: Paul W. Parmalee is professor emeritus of zooarchaeology and director emeritus of the McClung Museum at the University of Tennessee, Knoxville. Arthur E. Bogan is curator of aquatic invertebrates at the North Carolina State Museum of Natural Sciences, Raleigh.

Download or read book Freshwater Biodiversity written by David Dudgeon and published by Cambridge University Press. This book was released on 2020-05-21 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

The most comprehensive reference source available about the lakes, Lake Erie and Lake St. Clair Handbook is an ideal guide for anglers, boaters, swimmers, beach walkers—anyone who uses and enjoys the lakes. The handbook explains, in simple terms, the reasons for the scenic beauty and the natural events that occur in the coastal and offshore waters of Lake Erie and Lake St. Clair, including the St. Clair, Detroit, and Niagara rivers extending from Sarnia, Ontario, to Niagara-on-the-Lake, New York. Individual chapters focus on the land, air, water, and life forms that comprise the natural history and environment of the region—the shoreline topography, wind and weather patterns, water temperature cycles and water level changes, the ecology, and indigenous animal life. Lake Erie and Lake St. Clair Handbook enhances our understanding and appreciation of the lakes and their surroundings by addressing fundamental questions about the Lake Erie region: • how Lake Erie was formed through glacial processes • why daily and seasonal weather patterns occur • causes of the water currents and waves • causes of temperature patterns in the lakes • the location of productive reef features • the species of fish and birds found in the area • the importance of the wetlands • the effect of current and past pollution on the aquatic life in the lakes
Download or read book Eel Biology written by K. Aida and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a food resource in both Eastern and Western countries, the eel is an important fish. Over the years, remarkable progress has been achieved in understanding the mysterious life cycle of eels that has fascinated scientists since the age of Aristotle. The spawning area of the Japanese eel was discovered and the migratory route of its larvae was elucidated. With the development of techniques for artificial induction of gonadal maturation, it became possible to obtain hatched larvae. Larval rearing to the leptocephalus stage, one of the most difficult tasks involved in eel culture, finally was achieved. By presenting these important breakthroughs, Eel Biology will be of great help in the development of effective management strategies for maintaining stable eel populations. With contributions by leading experts, this book is a valuable source for researchers as well as industry technicians in the fields of aquatic biology, aquaculture, and fisheries.

Download or read book Ecological Connectivity among Tropical Coastal Ecosystems written by Ivan Nagelkerken and published by Springer Science & Business Media. This book was released on 2009-09-23 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mangrove forests, seagrass beds, and coral reefs are circumtropical ecosystems that are highly productive, and provide many important biological functions and economic services. These ecosystems cover large surface areas in the shallow tropical coastal seascape but have suffered from serious human degradation, especially in the last few decades. Part of their diversity, productivity, and functioning seems to be based on their juxtaposition. Especially in the last decade significant advances have been made on new insights into their ecological connectivity. This authoritative book provides a first-time comprehensive review of the major ecological interactions across tropical marine ecosystems that result from the mutual exchange of nutrients, organic matter, fish, and crustaceans. A group of leading authors from around the world reviews the patterns and underlying mechanisms of important biogeochemical and biological linkages among tropical coastal ecosystems in 15 chapters. Included are chapters that review cutting-edge tools to study and quantify these linkages, the importance of such linkages for fisheries, and how tropical ecosystems should be conserved and managed for sustainable use by future generations. The book uses examples from all over the world and provides an up-to-date review of the latest published literature. This book is a ‘must read’ for professionals working on the conservation, management, and ecology of mangrove, seagrass and coral reef ecosystems.

This book was released on 2013 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is also recommended that efforts be increased to farm lower trophic levels species and optimize feeds and feeding in order to minimize ecosystems impacts and ensure long-term sustainability. Similarly, risk assessments and/or environmental impact assessment and monitoring must always be in place before establishing offshore farms, and permanent environmental monitoring must be ensured. All coastal nations should be prepared to engage actively in developing the technological, legal and financial frameworks needed to support the future development of offshore mariculture to meet global food needs. The workshop report highlights the major opportunities and challenges for a sustainable mariculture industry to grow and further expand off the coast.
Download or read book Gene Drives on the Horizon written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-08-28 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on gene drive systems is rapidly advancing. Many proposed applications of gene drive research aim to solve environmental and public health challenges, including the reduction of poverty and the burden of vector-borne diseases, such as malaria and dengue, which disproportionately impact low and middle income countries. However, due to their intrinsic qualities of rapid spread and irreversibility, gene drive systems raise many questions with respect to their safety relative to public and environmental health. Because gene drive systems are designed to alter the environments we share in ways that will be hard to anticipate and impossible to completely roll back, questions about the ethics surrounding use of this research are complex and will require very careful exploration. Gene Drives on the Horizon outlines the state of knowledge relative to the science, ethics, public engagement, and risk assessment as they pertain to research directions of gene drive systems and governance of the research process. This report offers principles for responsible practices of gene drive research and related applications for use by investigators, their institutions, the research funders, and regulators.
