Download or read book Indicators of Environmental Quality written by William A. Thomas and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researchers and agencies collect reams of objective data and authors publish volumes of subjective prose in attempts to explain what is meant by environmental quality. Still, we have no universally recognized methods for combining our quantitative measures with our qualitative concepts of environ ment. Not all of our environmental goals should be reduced to mere numbers, but many of them can be; and without these quantitative terms, we have no way of defining our present position nor of selecting positions we wish to attain on any logically established scale of environmen tal values. Stated simply, in our zeal to measure our environment we often forget that masses of numbers describing a system are insufficient to understand it or to be used in selecting goals and priorities for expending our economic and human resources. Attempts at quantitatively describing environmental quality, rather than merely measuring different environmental variables, are relatively recent. This condensing of data into the optimum number of terms with maximum information content is a truly interdisciplinary challenge. When Oak Ridge National Laboratory initiated its Environmental Program in early 1970 under a grant from the National Science Foundation, the usefulness of environmental indicators in assessing the effects of technology was included as one of the initial areas for investigation. James L. Liverman, through his encouragement and firm belief that these indicators are indispensable if we are to resolve our complex environmental problems, deserves much of the credit for the publication of this book.

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 Stock Identification Methods written by Steven X. Cadrin and published by Academic Press. This book was released on 2013-10-04 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stock Identification Methods, 2e, continues to provide a comprehensive review of the various disciplines used to study the population structure of fishery resources. It represents the worldwide experience and perspectives of experts on each method, assembled through a working group of the International Council for the Exploration of the Sea. The book is organized to foster interdisciplinary analyses and conclusions about stock structure, a crucial topic for fishery science and management. Technological advances have promoted the development of stock identification methods in many directions, resulting in a confusing variety of approaches. Based on central tenets of population biology and management needs, this valuable resource offers a unified framework for understanding stock structure by promoting an understanding of the relative merits and sensitivities of each approach. - Describes 18 distinct approaches to stock identification grouped into sections on life history traits, environmental signals, genetic analyses, and applied marks - Features experts' reviews of benchmark case studies, general protocols, and the strengths and weaknesses of each identification method - Reviews statistical techniques for exploring stock patterns, testing for differences among putative stocks, stock discrimination, and stock composition analysis - Focuses on the challenges of interpreting data and managing mixed-stock fisheries

Book excerpt: In response to a request,in 2009, by the Lake Erie Island Chapter of the Black Swamp Conservancy, the Flora of the Erie Islands: Its Origin, History and Change is published to assist their conservation activities and programs. Completed in 1976 and, in 1979, scheduled to be although not published, xerographic copies of the manuscript were provided to researchers studying the islands' flora. As a result, the unpublished manuscript was widely cited in publications during the past 35 years and,in published form, remains a primary research resource concerning the flora of the Erie Archipelago.
