Presents the first overall synthesis of patterns of plant biodiversity in the species rich savannas and seasonally dry forests of the Neotropics Provides definitions of seasonally dry forests and savannas and maps of their distributionEmphasizes conservation issues, such as the identification of areas of significant species diversity or endemismTakes an interdisciplinary approach that ranges from a discussion of new inventories of species in poorly known areas to the detailing of the modern techniques of molecular biogeographic analysis
More often than not, when people think of a neotropical forest, what comes to mind is a rain forest, rather than a dry forest. Just as typically, when they imagine a savanna, they visualize the African plains, rather than those dry woodlands and grasslands found in the Neotropics. These same preconceptions can be found among scientists, as these neotropical biomes receive nowhere near the attention they should - in terms of both research and conservation -considering the amount of land they encompass and the diversity of vegetation they contain.
Neotropical Savannas and Dry Forests: Plant Diversity, Biogeography, and Conservation provides an engaging synthesis of information on the plant diversity and geography, as well as the conservation status, of these species-rich areas. This impressive compilation is the result of a plant diversity symposium that took place during an international conference on tropical savannas and seasonally dry forests held in 2003. Fifty leading scientists, representing a variety of disciplines have contributed to the chapters of this book in an effort to address three questions:
What are the patterns of diversity, species-richness and endemism of the floras of neotropical seasonally dry forest and savannas?
How and why did this endemism and diversity arise?
Are these ecosystems adequately protected and, if not, which areas should be elevated into priorities for conservation, and how can this be best achieved?
This work is the first extensive compilation of the patterns of plant biodiversity in these neotropical ecosystems. The overview also provides a summary of what is known of their evolutionary history, including an examination of the links to the development of analogous vegetation in Africa. In contrast to previously published titles that emphasize ecology and physiology, this work focuses on plant biodiversity and reviews molecular phylogenetic and molecular population genetic approaches to discovering biogeographic history.

"… the first extensive compilation focused specifically upon patterns of plant biodiversity in the species-rich savannas and seasonally dry forests of the neotropics. This scholarly and expert 484-page overview (contributed to by 59 contributors from around the world) succinctly summarizes what is currently known of the evolutionary history of these particular ecosystems, including links to the development of analogous vegetation in Africa. …focus on plant biodiversity and the molecular phylogenies and molecular population genetics for uncovering the biogeographic history of these ecosystems making it a seminal and necessary addition to professional and academic library Biological Sciences and Environmental Studies reference collections."
Midwest Book Review, August 2006
"Editors and contributors should be congratulated for putting this exciting interdisciplinary synthesis together. This volume is a must have for anyone who is interested in ecology, floristics, phylogeny, and conservation of dry neotropical biomes."—
