Species. Freshwater mussels are the most rapidly declining group of animals in North America. This guide represents a first-ofits-kind reference to assist both biologists and naturalists in the identification and study of freshwater mussels. Freshwater Mussels of Texas contains 224 pages with 226 black and white photographs, 144 color photographs and 79 line drawings covering all 52 species found in Texas waters. Introductory sections cover basic anatomy, reproduction.
Synthesizes the ecology and natural history of North American freshwater mussels for scientists, natural resource professionals, students and natural history enthusiasts.
This text explores the natural history of Texas and more than 2900 springs in 183 Texas counties. It also includes an in-depth discussion of the general characteristics of springs - their physical and prehistoric settings, their historical significance, and their associated flora and fauna.
"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.
An essential reference for anyone involved in protecting the environment, this book identifies and describes Virginia's endangered species and suggests ways that they might be managed to ensure their survival. It incorporates the contributions of more than eighty biologists. The volume provides extensive information for each endangered species, including a description, a written summary and a map of its distribution in Virginia and North America, an overview of its natural history, a synopsis of its legal and recommended statuses, a discussion of threats to its continued survival in Virginia, and recommendations for its conservation. Color photographs are included for mot of the plants and animals described in the book. Virginia's Endangered Species, first published in 1991, won the 1992 Outstanding Book Award from the Wildlife Society, Southeastern Section, and was cited by the American Library Association as one of the nation's Notable Government Documents in 1993. Karen Terwilliger is associated with the Nongame and Endangered Wildlife Program of the Virginia Department of Game and Inland Fisheries.
During the last two decades, zooarchaeologists have increasingly focused aspects of their work on conservation biology. Zooarchaeological data represent an empirical record of past human-animal interactions, which provides conservation with a deep temporal perspective. There are many challenges that face the archaeologist as conservation biologist, however, that have little to do with deep time, faunal remains, and zooarchaeological method and theory. In this book we use a series of case studies with which each of the authors has relevant personal experience to explore the types of interdisciplinary challenges that zooarchaeologists face when crossing into the world of environmental management and animal conservation. Never has there been a greater need for multi-vocal perspectives in conservation biology. This book shows zooarchaeologists how to use zooarchaeological perspectives to help meet those needs, while crossing traditional academic disciplinary boundaries.
Pearly mussels (Unionoidea) live in lakes, rivers, and streams around the world. These bivalves play important roles in freshwater ecosystems and were once both culturally and economically valuable as sources of food, pearls, and mother-of-pearl. Today, however, hundreds of species of these mussels are extinct or endangered. David L. Strayer provides a critical synthesis of the factors that control the distribution and abundance of pearly mussels. Using empirical analyses and models, he assesses the effects of dispersal, habitat quality, availability of fish hosts, adequate food, predators, and parasites. He also addresses conservation issues that apply to other inhabitants of fresh waters around the globe and other pressing issues in contemporary ecology.

Contrary to a generally held view that pearls are found by chance in oysters, almost all are now produced from farms. This book is a comprehensive treatment of all aspects of the biology of pearl oysters, their anatomy, reproduction, genetics, diseases, etc. It considers how they are farmed from spawning and culturing larvae in hatcheries to adults in the ocean; how various environmental factors, including pollution affect them; and how modern techniques are successfully producing large numbers of cultured pearls. This is the ultimate reference source on pearl oysters and the culture of pearls, written and edited by a number of scientists who are world experts in their fields. - Comprehensive treatment of pearl oyster biology and pearl culture - Written by the top world authorities - Highly illustrated and figured - Of practical relevance to a broad readership, from professional biologists to those involved in the practicalities and practice of pearl production
