Download or read book A Guide to Endangered and Threatened Species in Virginia written by Karen Terwilliger and published by Univ. of Tennessee Press. This book was released on 1995 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Condensed from Virginia s endangered Species, this concise guide identifies the most vulnerable plants and animals found in the Commonwealth. It contains one-page summaries of the biology and ecology of the endangered and threatened species, including physical descriptions and reviews of each species distribution, habitat, life history, and vulnerability. A color photograph is provided for almost every species. An introduction summarizes Virginia s natural habitats, conservation laws, and the responsibilities of the various state agencies involved in the conservation of biotic diversity. Several appendixes are also included, providing quick reference to definitions of legal status and the status of each listed species. This book will prove useful both as a reference work and a field tool for professional biologists and ecologists, as well as land managers, planners, developers, teachers, students, and all others seeking information about conserving and wisely managing Virginia s biological heritage. The Coordinators: Karen Terwilliger is associated with the Nongame and Endangered Wildlife Program of the Virginia Department of Game and Inland Fisheries. John R. Tate works for the Office of Plant and Pest Services of the Virginia Department of Agriculture and Consumer Sciences. "

Download or read book Freshwater Bivalve Ecotoxicology written by Jerry L. Farris and published by CRC Press. This book was released on 2006-11-16 with total page 400 pages. 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.
