Genetics and the Extinction of Species — DNA and the Conservation of Biodiversity.

The issue of species extinction is arguably the most emotive factor in conservation, yet being difficult to observe in nature, it is not well understood. The importance of genetic processes in extinction is controversial; demographic stochasticity generally holds favour as the most likely cause with most conservation biologists. However, some recent papers have produced evidence that inbreeding depression may well play a key role in population extinction (Saccheri et al., 1998). It is therefore timely to have a book exploring the relationship between genetics and the extinction of species. The book contains eight chapters each contributed by different authors and the coverage reflects their expertise, producing a mixture of case studies and process-based approaches.
