A land of incredible natural resources, the South American continent is rich in plant and animal species. Among birds alone, over 3,100 species are either resident or migrant. Birds are some of South America's treasures and also one of its most endangered resources. Hence the need for a descriptive record of South American birds that will serve both professional and amateur bird students and encourage conservation of these magnificent species. Although South American birds elicit much popular and scientific interest, they have never been completely or satisfactorily described and cataloged in a single, published source. The Birds of South America, projected to be a four-volume work, thus fills a critical void. Starting from a museum approach, the authors have examined specimens of each subspecies, comparing them visually and trying to discern the patterns in their plumage variation, both intra- and inter-specifically. They take a new look at bird systematics, reassessing relationships in light of new information. Perhaps most important, they combine this review and analysis with extensive field observations to give an accurate, incisive portrait of the birds in nature. At a time when rapid development is devastating millions of acres of tropical habitat in South America, this record of an endangered resource becomes crucial. If the birds and other plants and animals of South America are to be saved, they must first be known and appreciated. The Birds of South America is a major step in that direction. Volume I includes the Jays and Swallows; Wrens, Thrushes, and Allies; Vireos and Wood-warblers; Tanagers, Icterids, and Finches. The remaining volumes of The Birds of South America will be: Volume III: The Nonpasserines (Landbirds) Volume IV: The Nonpasserines (Waterbirds) No release date has been set for the remaining volumes.

"A superb resource for understanding the diversity of the modern discipline of biogeography, and its history and future, especially within geography departments. I expect to refer to it often." - Professor Sally Horn, University of Tennessee "As you browse through this fine book you will be struck by the diverse topics that biogeographers investigate and the many research methods they use.... Biogeography is interdisciplinary, and a commonly-voiced concern is that one biogeographer may not readily understand another's research findings. A handbook like this is important for synthesising, situating, explaining and evaluating a large literature, and pointing the reader to informative publications." - Geographical Research "A valuable contribution in both a research and teaching context. If you are biologically trained, it provides an extensive look into the geographical tradition of biogeography, covering some topics that may be less familiar to those with an evolution/ecology background. Alternatively, if you are a geography student, researcher, or lecturer, it will provide a useful reference and will be invaluable to the non-biogeographer who suddenly has the teaching of an introductory biogeography course thrust upon them." - Adam C. Algar, Frontiers of Biogeography The SAGE Handbook of Biogeography is a manual for scoping the past, present and future of biogeography that enable readers to consider, where relevant, how similar biogeographical issues are tackled by researchers in different 'schools'. In line with the concept of all SAGE Handbooks, this is a retrospective and prospective overview of biogeography that will: Consider the main areas of biogeography researched by geographers Detail a global perspective by incorporating the work of different schools of biogeographers Ecplore the divergent evolution of biogeography as a discipline and consider how this diversity can be harnessed Examine the interdisciplinary debates that biogeographers are contributing to within geography and the biological sciences. Aimed at an international audience of research students, academics, researchers and practitioners in biogeography, the text will attract interest from environmental scientists, ecologists, biologists and geographers alike.

The research paper "Extinction Risk from Climate Change" published in the journal Nature in January 2004 created front-page headlines around the world. The notion that climate change could drive more than a million species to extinction captured both the popular imagination and the attention of policy-makers, and provoked an unprecedented round of scientific critique. Saving a Million Species reconsiders the central question of that paper: How many species may perish as a result of climate change and associated threats? Leaders from a range of disciplines synthesize the literature, refine the original estimates, and elaborate the conservation and policy implications. The book: examines the initial extinction risk estimates of the original paper, subsequent critiques, and the media and policy impact of this unique studypresents evidence of extinctions from climate change from different time frames in the pastexplores extinctions documented in the contemporary recordsets forth new risk estimates for future climate changeconsiders the conservation and policy implications of the estimates. Saving a Million Species offers a clear explanation of the science behind the headline-grabbing estimates for conservationists, researchers, teachers, students, and policy-makers. It is a critical resource for helping those working to conserve biodiversity take on the rapidly advancing and evolving global stressor of climate change-the most important issue in conservation biology today, and the one for which we are least prepared.
