Oil And Related Toxicant Effects On Waterfowl Immune Defenses

Management of wild waterfowl has become increasingly intensive. Many birds now hatch in managed nesting cover or in artificial nesting structures, use man-made wetlands, and winter on crowded refuges while consuming a grain diet The water they use is often limited in supply and may contain residues from its many prior users. Unfortunately, intensified management often results in new problems, among which disease is important There are many similarities between the current form of management used for some waterfowl and that used in domestic animals. In both, the objective is to maintain a healthy, productive population. Dealing with health problems in waterfowl will benefit from combining the skills of veterinary medicine and wildlife ecology. Revisiting this book after 15 years allowed me to consider changes at the interface between the two disciplines. Veterinary medicine traditionally has been concerned with the individual and with treating sick animals, while the ecologist is concerned with populations and the manager has limited interest in treating sick birds. During this period there has been a marked increase in awareness among veterinarians that they have a responsibility in wildlife and conservation biology. Curricula of many veterinary colleges now include material on non-domestic animals and attempt to put disease in an ecological context. Also during this time, waterfowl managers have become more aware of disease as a factor in population biology and there are early attempts to put numbers to "disease" in models of continental waterfowl populations.

Provides wildlife professionals with cutting-edge scientific information on the most damaging and newly emerging wildlife diseases. Wildlife diseases and their implications are at the forefront of many sectors of scientific endeavor, especially in the wake of the COVID-19 pandemic. Nearly 60 percent of all human diseases and 75 percent of all emerging infectious diseases are zoonotic. Edited by pioneering wildlife veterinarians David A. Jessup and Robin W. Radcliffe, Wildlife Disease and Health in Conservation explores the origins and impacts of as well as the responses to the most damaging and persistent diseases currently threatening wildlife conservation. Focusing mainly on newer, invasive, and controversial wildlife health challenges, this book also reexamines classic diseases that provide warnings and important lessons for wildlife professionals and policy makers. Each chapter offers cutting-edge scientific information and extensive references to help readers plan for, respond to, and conduct research on these serious health challenges. This book: • Reports crucial findings on newly emerging diseases and how to recognize and manage them • Explores the health of critical but often neglected aquatic ecosystems, including both vertebrate and invertebrate examples • Covers a vast diversity of wildlife health threats, from epizootic bighorn sheep pneumonia and African swine fever to sea star wasting disease, avian influenza, and rabbit hemorrhagic disease • Explains zoonotic dangers to humans, including coronaviruses • Includes information on marine and aquatic species, wild ungulate species, carnivores and omnivores, birds, and more • Provides insight into the social, legal, financial, and political factors that may override or influence conservation priorities in response to biomedical challenges Featuring detailed and attractive field notes–style illustrations by Laura Donohue and essential essays from experts in the field, Wildlife Disease and Health in Conservation combines theory and practice to inform and inspire wildlife health and conservation.

Ecotoxicity and Human Health emphasizes the relationships between toxicity, ecological systems, and human health. It focuses on the extent and nature of hazardous waste sites and how their effects may be studied in humans and other systems, using in vitro models, biomarkers of cellular and molecular damage, and animal models. It also includes considerable information on bioremediation, legal and regulatory issues, public perceptions and societal responses, quantitative modeling and analysis, and international directives. One of the unique features of Ecotoxicity and Human Health is its coverage of the legislative actions that have occurred over the past two decades and which have most affected the issue of hazardous waste. The book discusses the Superfund Statute, the Resource Conservation and Recovery Act (RCRA), the Toxic Substances Control Act (TSCA), the Ocean Dumping Act of 1972, the Rio Conference, United Nations Declarations, EC Regulations and Directives, and selected state legislation.
