With contributions from a wide array of economists, ecologists, and government agency professionals, Economics and Ecological Risk Assessment: Applications to Watershed Management provides a multidisciplinary approach to environmental decision-making at a watershed level. It introduces the fields of ecological risk assessment (ERA) and economic ana

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.

The new edition of Introduction to Wildlife and Fisheries marks the return of first and only book to integrate both the wildlife and fisheries into a single textbook at the introductory level. Thoroughly updated, with an inviting new design, the Second Edition offers the most current and accessible coverage of essential biological concepts and their applications, principles of resource management and conservation, and contemporary and public policy issues affecting today’s scientists and resources.
