Nearly 700 species of plants may become extinct by the year 2000. Faced with this overwhelming prospect, plant conservationists must take advantage of every technique available. This unique work summarizes our current knowledge of the genetics and population biology of rare plants, and integrates it with practical conservation recommendations. It features discussions on the distribution and significance of genetic variation, management and evaluation of rare plant germplasm, and conservation strategies for genetic diversity. Case studies focusing on specific problems offer important insights for today's challenges in rare plant conservation.

It is a distressing truism that the human race during the last millennium has caused the exponential loss of plant genetic diversity throughout the world. This has had direct and negative economic, political and social consequences for the human race, which at the same time has failed to exploit fully the positive benefits that might result from conserving and exploiting the world's plant genetic resources. However, a strong movement to halt this loss of plant diversity and enhance its utilisation for the benefit of all humanity has been underway since the 1960's (Frankel and Bennett, 1970; Frankel and Hawkes, 1975). This initiative was taken up by the Convention on Biological Diversity (CBD, 1992) that not only expounds the need to conserve biological diversity but links conservation to exploitation and development for the benefit of all. Article 8 of the Convention clearly states the need to develop more effective and efficient guidelines to conserve biological diversity, while Article 9, along with the FAO International Undertaking on Plant Genetic Resources, promotes the adoption of a complementary approach to conservation that incorporates both ex situ and in situ techniques.

This impressive author team brings the wealth of advances in conservation genetics into the new edition of this introductory text, including new chapters on population genomics and genetic issues in introduced and invasive species. They continue the strong learning features for students - main points in the margin, chapter summaries, vital support with the mathematics, and further reading - and now guide the reader to software and databases. Many new references reflect the expansion of this field. With examples from mammals, birds, reptiles, fish, amphibians, plants and invertebrates, this is an ideal introduction to conservation genetics for a broad audience. The text tackles the quantitative aspects of conservation genetics, and has a host of pedagogy to support students learning the numerical side of the subject. Combined with being up-to-date, its user-friendly writing style and first-class illustration programme forms a robust teaching package.

Conservation in protected areas has focused on preserving biodiversity of ecosystems and species, whereas conserving the genetic diversity contained within species has historically often been ignored. However, maintaining genetic diversity is fundamental to food security and the provision of raw materials and it is best preserved within plants' natural habitats. This is particularly true for wild plants that are directly related to crop species and can play a key role in providing beneficial traits, such as pest or disease resistance and yield improvement. These wild relatives are presently threatened due to processes of habitat destruction and change and methodologies have been adapted to provide in-situ conservation through the establishment of genetic reserves within the existing network of protected areas.Providing a long-awaited synthesis of these new methodologies, this book presents a practical set of management guidelines that can be used for the conservation of plant genetic diversity of crop wild relatives in protected areas.

The book aims to address the lack of information on the experiences of others by providing a comparative analysis of national access and benefit-sharing laws and policies in the 41 Pacific Rim countries that signed the CBD. It provides key insights on the main characteristics of selected access and benefit-sharing (ABS) policies and laws, their development, and implementation process. It contains a detailed comparative analysis of existing laws and policies. It presents four case studies of countries with regulations in place and contrasts them with four case studies of countries that are struggling to develop their regulations. It ends by discussing options of an international regime on ABS and a summary analysis of the main lessons and recommendations from the study.
