The biological diversity of the planet is being rapidly depleted due to the direct and indirect consequences of human activity. As the size of animal and plant populations decreases, loss of genetic diversity reduces their ability to adapt to changes in the environment, with inbreeding and reduced fitness inevitable consequences for most species. This textbookprovides a clear and comprehensive introduction to genetic principles and practices involved in conservation. Topics covered include : evolutionary genetics of natural populations ; loss of genetic diversity in small populations ; inbreeding and loss of fitness ; population fragmentation ; resolving taxonomie uncertainties ; genetic management of threatened species ; contributions of molecular genetics to conservation. The text is presented in an easy-to-follow format, with main points and ternis clearly highlighted. Each chapter concludes with a concise summary, which, together with worked examples and problems and answers, illuminates the key principles covered. Text boxes containing interesting case studies and other additional information enrich the content throughout, and over 100 beautiful pen-and-ink drawings help bring the material to life. Written for advanced undergraduate and graduate students studying conservation, this bock will be equally useful to practising conservation biologists and wildlife managers needing an accessible introduction to this important field.
