Book Description
This report represents the first national assessment of PBDEs in the U.S. coastal zone. Results suggest that they are widely distributed nationally. Several regions, including the northern Mid-Atlantic, central Gulf of Mexico, Southern California, Pacific Northwest and the Great lakes have elevated PBDE concentrations compared with other coastal regions. Furthermore, PBDE concentrations are positively correlated with human population density along the U.S. coastline. The national and regional perspectives provided herein are intended to support research, local monitoring, and to assist resource managers and policy makers tasked with making regulatory decisions about these contaminants.

Book Description
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.

Book Description
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.

Book Description
Plastic Waste and Recycling: Environmental Impact, Societal Issues, Prevention, and Solutions begins with an introduction to the different types of plastic materials, their uses, and the concepts of reduce, reuse and recycle before examining plastic types, chemistry and degradation patterns that are organized by non-degradable plastic, degradable and biodegradable plastics, biopolymers and bioplastics. Other sections cover current challenges relating to plastic waste, explain the sources of waste and their routes into the environment, and provide systematic coverage of plastic waste treatment methods, including mechanical processing, monomerization, blast furnace feedstocks, gasification, thermal recycling, and conversion to fuel. This is an essential guide for anyone involved in plastic waste or recycling, including researchers and advanced students across plastics engineering, polymer science, polymer chemistry, environmental science, and sustainable materials. - Presents actionable solutions for reducing plastic waste, with a focus on the concepts of collection, re-use, recycling and replacement - Considers major societal and environmental issues, providing the reader with a broader understanding and supporting effective implementation - Includes detailed case studies from across the globe, offering unique insights into different solutions and approaches

Book Description
The fundamental concept of The Biology and Identification of the Coccidia (Apicomplexa) of Carnivores of the World is to provide an up-to-date reference guide to the identification, taxonomy, and known biology of apicomplexan intestinal and tissue parasites of carnivores including, but not limited to, geographic distribution, prevalence, sporulation, prepatent and patent periods, site(s) of infection in the definitive and (if known) intermediate hosts, endogenous development, cross-transmission, pathology, phylogeny, and (if known) their treatments. These data will allow easy parasite recognition with a summation of virtually everything now known about the biology of each parasite species covered. The last (very modest) and only treatise published on this subject was in 1981 so this book fills a fundamental gap in our knowledge of what is now known, and what is not, about the coccidian parasites that infect and sometimes kill carnivores and/or their prey that can harbor intermediate stages, including many domestic and game animals. - Offers line drawings and photomicrographs of many parasite species that will allow easy diagnosis and identification by both laypersons and professionals (veterinarians, wildlife biologists, etc.) - Presents a complete historical rendition of all known publications on carnivore coccidia for all carnivore families and evaluates the scientific and scholarly merit of each apicomplexan species relative to the current body of knowledge - Provides a complete species analysis and their known biology of all coccidia described from each carnivore lineage and species - Reviews the most current taxonomy of carnivores and their phylogenetic relationships to help assess host-specificity patterns that may be apparent - Evaluates what little cross-transmission work is available to help understand the complexities of those coccidians that use two hosts (e.g., Sarcocystis, Besnoitia, and others) - Provides known treatments for the various parasite genera/species

Book Description
Thermal Imaging Techniques to Survey and Monitor Animals in the Wild: A Methodology provides a manual for anyone interested in understanding thermal imaging and its usefulness in solving a wide range of problems regarding the observation of wildlife. In the last decade, the cost of thermal imaging technology has significantly decreased, making the equipment more widely available. This book offers an overview of thermal physics and the thermal imager, along with a methodology to optimize the window of opportunity so that wildlife can be observed and studied in their natural habitat. Users will find the knowledge and tools to formulate a sound survey design, with detailed sections on the theory and performance characteristics of thermal imaging cameras utilizing cooled quantum detectors as the sensitive element and additional information on the uncooled micro bolometric imagers which have been introduced into the camera market in past decades. The methodology presented is logical and simple, yet it presents a detailed understanding of the topic and how it applies to the critically interlinked disciplines of biology, physics, micrometeorology, and animal physiology. - Covers the technical aspects of thermal imaging allowing readers to design better experiments - Provides a clear description of the properties of thermal imaging - Includes approaches to consider before integrating thermal cameras into a field
