Available in PDF, EPUB and Kindle. Book excerpt: The concentrations of polychlorinated biphenyls (PCBs) and residues of organochlorine pesticides (HEOD and DDE) were measured in livers of otters (Lutra lutra) from different areas in Scotland. Whilst HEOD and DDE occurred at very low concentrations only, PCBs were present in high levels in some areas, the highest in Shetland (geom mean 2.05 ppm wet wt), related probably to high levels in sediments in the north-east Atlantic. PCBs were a mixture of congeners in which higher-chlorinated ones predominated, especially 138, 153, 170 and 180, a pattern comparable to that observed in otters from continental Europe. Individual values of total PCB reached levels of over 14 ppm wet weight, even in otters in good condition in thriving populations. Otter population densities were known in some of the study areas; in Shetland numbers increased over the study period, and the density was relatively high also elsewhere in Scotland. There was a strong negative correlation between PCB and body condition, but no correlation between PCB concentration and age of otters (mean age=4.1 years), which suggests that PCBs do not accumulate substantially in otters in the long term. The observations cast doubt on the significance of published 'critical levels' of PCBs to otter populations, based on data obtained from captive mink.

Book excerpt: Otters are highly charismatic and popular animals of very considerable concern to conservationists worldwide. Written by the pre-eminent authority in the field, this book builds on the reputation of the author's landmark monograph of the European otter, Wild Otters (OUP, 1995). Furthermore, its broader scope to include all species of otter in North America as well as Europe and elsewhere leads to a deeper synthesis that greatly expands the book's overall relevance and potential readership. Aimed at naturalists, scientists and conservationists, its personal style and generously illustrated text will appeal to amateurs and professionals alike. It emphasises recent research and conservation management initiatives for all 13 species of otter worldwide, incorporates recent molecular research on taxonomy and population genetics, and discusses the wider implications of otter studies for ecology and conservation biology. As well as enchanting direct observations of the animals, there is guidance about how and where to watch and study them. From otters in the British and American lakes and rivers, to sea otters in the Pacific Ocean, giant otters in the Amazon and other species in Africa and Asia, this book provides an engaging approach to their fascinating existence, to the science needed to understand it, and to the very real threats to their survival.

Available in PDF, EPUB and Kindle. Book excerpt: Carnivores are the focus of intense attention and resources in conservation biology. It is often argued that, because carnivores are at the top of the food chain, if they are protected, then other taxa will also be afforded adequate protection. Carnivores are also charismatic and compete with humans for dwindling space and environmental resources. In the past 10 years, theoretical and empirical studies on carnivores have developed very quickly. This volume reviews and summarises the current state of the field, describes limitations and opportunities for carnivore conservation, and offers a conceptual framework for future research and applied management. As such it will be of interest to students and researchers of conservation biology, mammalogy, animal behaviour, ecology and evolution.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The last half-century has shown a dramatic increase in the standard of living of millions of people in Europe, North America and many parts of the Third World. This has, in many ways been brought about by scientific and technical developments which were initiated in the 1940s and 1950s. Promises were then made that nuclear energy would provide electricity so cheap that it would not need metering, pesticides would end malnutrition throughout the world and plastics and other synthetic chemicals would revolutionise our manufacturing industry and our way of life. Whilst some of these promises have been fulfilled, the problems of long-term health risks to humans and wildlife arising from the use, production and disposal of these products were either unknown or deliberately understated. Nuclear power is rendered economically unviable when the real cost of decommissioning and storage of waste for several millenia is included, and the effects on health of both humans and wildlife of early pest eradication programmes with organochlorine pesticides were well documented in Rachel Carson's "Silent Spring". Evidence of the effects of aerosols and refrigerants on depletion of the ozone layer has led to restriction on the use of CFCs, and there is now increasing evidence of climate change resulting from our profligate use of fossil fuels.

Book excerpt: The edited book Pesticides - Toxic Aspects contains an overview of attractive researchers of pesticide toxicology that covers the hazardous effects of common chemical pesticide agents employed every day in our agricultural practices. The combination of experimental and theoretical pesticide investigations of current interest will make this book of significance to researchers, scientists, engineers, and graduate students who make use of those different investigations to understand the toxic aspects of pesticides. We hope that this book will continue to meet the expectations and needs of all interested in different aspects of pesticide toxicity.

Book excerpt: From an October 1998 symposium at the University of Maryland, College Park, 13 papers explore not only the effects of contaminants on wildlife, but also endpoints and study design, and applying research findings to ecological risk assessment at contaminated sites. The topics include contaminants as a cause for perturbations in terrestrial vertebrate populations, the statistical design of wildlife toxicology studies, and estimating population-level effects on wildlife based on individual-level exposures.

This book was released on 2019-03-01 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.
