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.

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.
