A Primer of Conservation Biology, Fourth Edition incorporates background, theory, and examples in a lively and readable text that will appeal to a wide audience and stimulate interest in conservation biology. The book provides the most up-to-date perspective on many high-profile issues in the field, such as sustainable development, global warming, payments for ecosystem services, and strategies to save species on the verge of extinction. The Primer is divided into nine chapters, focusing successively on biological diversity and its value, the threats to biological diversity, conservation at the population and species levels, protecting, managing and restoring ecosystems, and sustainable development. The book provides many examples of successful conservation approaches, such as one involving sea turtles in Brazil, and ends with suggestions for a future agenda. Throughout, the choice of examples is well balanced to show the full range of species, habitats, and geographic areas of the world. These examples are also selected to demonstrate the controversies in the field, and stimulate thought and discussion. The links between conservation biology and environmental law, environmental economics, philosophy, social sciences and anthropology, park management, and government policy are clearly presented. The book is very well illustrated and is now in color. The reader-friendly text is backed by an extensive bibliography (covering literature through 2008) and a glossary. There is an annotated list of suggested readings and websites and discussion questions at the end of each chapter. Sources of further information are given in an Appendix.
