Building on the success of its popular predecessor, the second edition of Ecotoxicology of Amphibians and Reptiles presents newly available findings on the species that are important environmental indicators. This new edition covers nearly twice as many topics as the first, including recent developments in the ecotoxicology of amphibians and reptiles, the current status of these animals, and intrinsic factors that affect their susceptibility to contaminants. The book also provides the latest information on specific groups of contaminants and their effects and body burdens in herpetafauna. After a review of how contaminants interact with other ecological factors, the text explores concerns for the future. New in the second edition: New research on the effects of pesticides, heavy metals, endocrine disrupting chemicals, and UVB Increased focus on the effects of contaminants rather than merely reporting residue information A synthesis of information on atrazine and its effects on gonads at low concentrations Coverage of the potentially alarming new cadre of chemicals that have recently or are about to come on the market for which there is very little or no information Important advances in surveying and monitoring One of the major factors behind the writing of the first edition was the worldwide phenomenon of declining amphibian populations. Although this decline has not abated, the breadth of research into its causes has expanded significantly. With chapter contributors carefully selected by the team of editors as leaders in their fields, this book provides an authoritative compendium of the most recent information on effects and residues coupled with a syntheses of what these numbers mean to science and policy.

This textbook presents a comprehensive examination of environmental science and ecotoxicology for undergraduate students. The material provides sufficient related background information leading to a competency to clearly understand ecotoxicology concepts and topics.

Ecotoxicology Essentials: Environmental Contaminants and Their Biological Effects on Animals and Plants provides a fundamental understanding of this area for students and professionals in ecotoxicology, ecology, conservation, chemistry, public health, wildlife management, fisheries, and many other disciplines. Although new chemicals and potential problems are developed every year, a basic education is essential to address these new challenges, and this work gives such training. Written with the regulatory framework in mind, the material guides readers on modelling, how to conduct assessments, and human and wildlife risk, focusing on effects on animals rather than transport of chemicals. Simple discussions of chemistry are complemented by coverage on the behavior of the animal, dynamics of the ecosystem, real-life situations like drought, and predators in the system - i.e., the natural system versus the lab setting. The book's first section contains chapters on the principles of contaminant toxicology including a brief history of the science of ecotoxicology, basic principles of the science, testing methods, and ways of determining if animals have been exposed to either acute or chronic concentrations of contaminants. The second section deals with the primary classes of contaminants including their chemical characteristics, sources, uses, and effects on organisms. The third section focuses on more complex issues such as the regulation of pollution, population and community effects, risk assessment and modelling.

"Natural Resource and Wildlife Administration" presents a clear perspective on natural resource administration in North America, how it developed, how it is currently structured, and where it might be heading. Intertwined areas of natural resources, including wildlife administration, fisheries, forestry, and other competitive land uses, are heavily discussed. The book covers the history of natural resource management in Europe and North America, proceeding to environmental law; agencies involved in wildlife and natural resource management; and the human dimensions of public relations and economic concerns.

"Natural Resource and Wildlife Administration" provides solid background on the history of natural resource conservation, critical laws protecting resources, and the nature of agencies. The interconnectedness among natural resources makes this a useful text for disciplines such as wildlife, fisheries, and forestry.
Covers the development of natural resource law and the conservation agencies in North America, and also provides models for international useExamines the roles of diverse federal, state, and non-governmental agencies, and how they cooperate as professionals to accomplish natural resources management Leads readers to a greater understanding of the politics and interplay of priorities in professional conservation biologyAssists the certification processes of professional societiesIncludes end-of-chapter questions for further thought and discussion, as well as offset boxes throughout the text to help explain more technical subjects
