Primack (conservation biology, Boston U.) presents this attractive volume introducing undergraduates and above to topics in conservation biology. Updated chapters conclude with chapter summaries and discussion questions and address successively: biological diversity and its value, threats to biological diversity, conservation at the population and species levels, protection and restoration of ecosystems, and sustainable development. Some chapters focus on recent ongoing conservation crises and projects. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
