Available in PDF, EPUB and Kindle. Book excerpt: If it is still true that more than 80% of the ornithologists in North America are primarily interested or engaged in ecological studies on birds (J. R. King and W. J. Bock, Final Report of the Workshop on a National Plan For Ornithology, 1978), then Volume 3 of Current Orni thology is preadapted for their consideration. All but one article in this volume are somehow concerned with the ecological aspects of the bi ology of birds. Variation in the scope of topical coverage is relatively broad, and includes conservation, reproduction, behavior, community structure, and evolutionary ecology. Three reviews concern the pervasive effects of man and industry on various bird populations of the world. Risebrough provides a de tailed description of the relationships between pesticides and bird pop ulations. Morrison ass es ses aspects of bird population numbers as in dicators of environmental change, and Temple outlines current research on endangered species. The broad spectrum of reproductive ecology of birds is variously treated in this volume. Jehl and Murray explore sexual selection and some of the resulting complexities in the evolution of sexual size di morphism, primarily in shorebirds. Lawton and Lawton are concerned with the relationships between social behavior and breeding systems in which variation is found in the age at which reproduction is first undertaken. Oring examines the wide-ranging variation in polyandrous breeding systems in birds, while Rohwer is concerned with adoption versus infanticide in birds, and their relationships to reproductive fit ness.

Download or read book Environmental Contaminants in Wildlife written by James P. Meador and published by CRC Press. This book was released on 1996-03-20 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many books have been written about the effects of toxic chemicals on wildlife, but none has focused on the practical question, "How much of a chemical in the tissues of an animal is harmful?" This book deals exclusively with that question. This comprehensive reference will certainly become the standard resource on the topic, offering authoritative and sound advice on many environmental contaminants. With chapters written by outstanding experts in their respective fields, this is not only a scholarly collection of discussions on different chemicals, but, for those who have the day-to-day task of evaluating the harm of environment contaminants to wildlife, this book will provide answers on, for example, how to interpret 1 ppm lead in the liver of a duck or fish. The authors explain the snags of interpreting data that are sometimes conflicting or insufficient, providing the reader with helpful advice on how to cope with such data. Each chapter reviews literature on a specific chemical, followed by a easy-to-understand summary providing technical guidance. For many years this book will remain the preeminent reference on how to interpret contaminant levels of organochlorine pesticides, PCBs, dioxins, PAHs, metals, selenium, and fluorides in wildlife.

Book excerpt: Discussing the interpretation of tissue concentrations of contaminants in wildlife, this updated edition of a bestseller draws on current scientific research and includes new chapters and greater emphasis on aquatic organisms. Each chapter provides a summary and review of a specific chemical along with direction on research methods and the interpretation of conflicting or insufficient data. Chapters include a comprehensive history of contaminant interpretation in wildlife and fish, the use of tissue residues in ecological risk assessment, and detailed coverage of all bioaccumulative contaminants and their physiologic affects.
Download or read book Wildlife Ecotoxicology written by John E. Elliott and published by Springer Science & Business Media. This book was released on 2011-08-27 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.

Book excerpt: Cutting across traditional subject boundaries, Principles of Ecotoxicology, Fourth Edition gives readers an integrated view of ecotoxicology, from molecules to ecosystems. This new edition of a bestselling textbook continues to emphasize principles rather than practice, providing the interdisciplinary perspective and grounding required for research. Organized into three sections, the book first describes the molecular structures, properties, and environmental fate of pollutants. It then deals with the effects of pollutants on living organisms at the molecular, cellular, and individual levels. Moving into population biology and population genetics, the third part of the book addresses a question of great interest to ecologists: What effects do pollutants have at the levels of population, community, and the whole ecosystem? The book also looks at how ecotoxicology is used in the biomonitoring of environmental pollution, the investigation of pollution problems, the conducting of field trials, the study of the development of resistance, and the growing area of environmental risk assessments. Throughout, examples and case studies illustrate the principles. This updated fourth edition includes new material on nanoparticle pollution, bioaccumulation, biomarkers, and chemical warfare in nature, as well as a new chapter on the future directions of ecotoxicology. A concise textbook that will also appeal to practicing ecotoxicologists, it provides a solid basis for understanding what happens to chemicals in the real world, where they go, how they ultimately degrade, and how they affect the individuals and populations that encounter them. What's New in This Edition Revised and updated material throughout A chapter on future directions of ecotoxicology New material on nanoparticle pollution and chemical warfare in nature Expanded coverage of bioaccumulation, biomarkers, and risk assessment for affected populations More case studies, many from the United States Discussion of neurotoxic and behavioral effects of pollutants Recent research on the decline of vultures and effects of neonicotinoids on bees Organic Pollutants: An Ecotoxicological Perspective, Second Edition(CRC Press, 2008), a companion volume to this book, covers the mechanistic aspects of ecotoxicology in more depth.

This book was released on 2012-12-06 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: `Are the Great Lakes getting better or worse?' This is the question that the public, scientists and managers are asking the International Joint Commission after a quarter-century of cooperative action by the United States and Canadian governments to clean up the Great Lakes. This volume contains papers from the workshop on Environmental Results, hosted in Windsor, Ontario, by the Great Lakes Science Advisory Board of the International Joint Commission, on September 12 and 13, 1996. The Great Lakes have been through almost a century of severe pollution from the manufacture, use and disposal of chemicals. In the 1960s wildlife biologists started to investigate the outbreaks of reproductive failure in fish-eating birds and ranch mink and to link these to exposure to organochlorine compounds. Human health researchers in the 1980s and 1990s linked growth retardation, behavioral anomalies and deficits in cognitive development with maternal consumption of Great Lakes fish prior to pregnancy. The Great Lakes became the laboratory where the theory of endocrine disruptors was first formulated. Now a group of Great Lakes scientists, hosted by the International Joint Commission, has compiled the story of the trends in the concentrations and effects of persistent toxic substances on wildlife and humans. The technical papers review the suitability of various organisms as indicators, and present the results of long-term monitoring of the concentrations and of the incidence of effects. The evidence shows that there was an enormous improvement in the late 1970s, but that in the late 1990s there are still concentrations of some persistent toxic substances that have stubbornly remained at levels that continue to cause toxicological effects.
