Biodiversity Conservation and Phylogenetic Systematics

This book is about phylogenetic diversity as an approach to reduce biodiversity losses in this period of mass extinction. Chapters in the first section deal with questions such as the way we value phylogenetic diversity among other criteria for biodiversity conservation; the choice of measures; the loss of phylogenetic diversity with extinction; the importance of organisms that are deeply branched in the tree of life, and the role of relict species. The second section is composed by contributions exploring methodological aspects, such as how to deal with abundance, sampling effort, or conflicting trees in analysis of phylogenetic diversity. The last section is devoted to applications, showing how phylogenetic diversity can be integrated in systematic conservation planning, in EDGE and HEDGE evaluations. This wide coverage makes the book a reference for academics, policy makers and stakeholders dealing with biodiversity conservation.

This book provides a fast and reliable way of understanding the role of phylogenetic diversity in present biodiversity conservation frame work It can be very useful for graduate, master and PhD students as it discusses basic questions such as the way we value phylogenetic diversity, gives guidelines for the choice of measures and provides detailed information on new methodological solutions The examples given here show both that it can be applied to many cases and be very useful to policy makers.

Phylogenetic diversity is now a key concept for biodiversity conservation due to its link to option value, evolutionary potential and to the possibility of guiding conservation across scales. Present facilities for obtaining molecular sequences and metagenomes are powering this research field, rendering available detailed information of phylogenetic diversity for a wide taxonomic sample in a short time frame. Along with modern methods of Systematic Conservation Planning this will certainly contribute to more explicit identification of conservation priorities and options.

This book brings an updated state of the art of phylogenetic diversity in conservation biology. Nineteen chapters written by scientists from research institutions of fourteen countries demonstrate that approaches for preserving the evolutionary heritage are now very tuned into human impacts and sustainability issues. The questions, methods and applications around which it is organized show the importance of phylogenetic diversity in avoiding biodiversity losses in the present extinction crisis. They touch important points such as the way we value phylogenetic diversity, the importance of thinking at a much wider sample of the Tree of Life, the choice of adequate measures. In methods section, new solutions, such as dealing with abundances, sampling effort, or with information coming from conflicting phylogenetic trees are provided. Application section includes study cases of different groups of organi sms, such as mammals, amphibians, butterflies and plants, in aquatic and terrestrial ecosystems, showing that phylogenetic diversity can be applied in a very wide range of situations, including as a way for predicting conservation status of species. This highlights the interest of this book not only for students and scientists of related disciplines but also for stakeholders and policy-makers working on the implementation of global, regional, and local agendas for biodiversity conservation.
