The implications of biodiversity loss for the global environment have been widely discussed, but only recently has attention been paid to its direct and serious effects on human health. Biodiversity loss affects the spread of human diseases, causes a loss of medical models, diminishes the supplies of raw materials for drug discovery and biotechnology, and threatens food production and water quality.

Biodiversity and Human Health brings together leading thinkers on the global environment and biomedicine to explore the human health consequences of the loss of biological diversity. Based on a two-day conference sponsored by the National Institutes of Health, the National Science Foundation, and the Smithsonian Institution, the book opens a dialogue among experts from the fields of public health, biology, epidemiology, botany, ecology, demography, and pharmacology on this vital but often neglected concern.

Contributors discuss the uses and significance of biodiversity to the practice of medicine today, and develop strategies for conservation of these critical resources. Topics examined include:

• the causes and consequences of biodiversity loss
• emerging infectious diseases and the loss of biodiversity
• the significance and use of both prescription and herbal biodiversity-derived remedies
• indigenous and local peoples and their health care systems
• sustainable use of biodiversity for medicine
• an agenda for the future

In addition to the editors, contributors include Anthony Artuso, Byron Bailey, Jensa Bell, Bhaswati Bhattacharya, Michael Boyd, Mary S. Campbell, Eric Chivian, Paul Cox, Gordon Cragg, Andrew Dobson, Kate Duffy-Mazan, Robert Engelman, Paul Epstein, Alexandra S. Fairfield, John Grupenhoff, Daniel Janzen, Catherine A. Laughin, Katy Moran, Robert McCaleb, Thomas Mays, David Newman, Charles Peters, Walter Reid, and John Vandermeer.

The book provides a common framework for physicians and biomedical researchers who wish to learn more about environmental concerns, and for members of the environmental community who desire a greater understanding of biomedical issues.

Rapid Ecological Assessment (REA) is a methodology developed by The Nature Conservancy to provide comprehensive and reliable information about biodiversity resources in situations where time and financial resources are limited. REAs utilize a combination of remote-sensed imagery, reconnaissance overflights, field data collection, and spatial information visualization to generate useful information for conservation planning.

Nature in Focus is an in-depth guide to the theory and practice of REAs, offering a detailed approach for assessing biodiversity in a rapid and integrative manner. It provides researchers with the essential tools and techniques they need to conduct an REA, and offers valuable advice about the planning and implementation aspects. The book:

• presents an overview of the REA methodology and sampling framework
• reviews all aspects of an REA: planning and management, mapping and spatial information, information management
• describes surveys of vegetation and fauna
• presents a generalized description of threat assessments
• explores the manner in which large amounts of data produced by different REA teams are integrated and synthesized into a cohesive set of management recommendations
• explains how the REA effort is documented, published, and disseminated
• offers a detailed REA case study

Also included is a set of twelve color maps that describe the sequence of mapping activities in the case-study REA, along with other map examples from a range of REAs. In addition to the case study, appendixes offer a full set of REA field forms for sampling, and a model "Scope of Work" that describes the nature of work to be conducted in an REA and outlines the roles and responsibilities of the participating organizations.

Nature in Focus presents the collective experience of more than ten years of REA field-testing. Conservation practitioners and biodiversity scientists who are involved with REA initiatives, along with managers, policymakers, and others involved with conservation programs will find the book a useful and nontechnical guide to an essential element of successful conservation.

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 study
• presents evidence of extinctions from climate change from different time frames in the past
• explores extinctions documented in the contemporary record
• sets forth new risk estimates for future climate change
• considers 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.
