Book Description
"At places distant from where you are, but also uncomfortably close," writes David Takacs, "a holocaust is under way. People are slashing, hacking, bulldozing, burning, poisoning, and otherwise destroying huge swaths of life on Earth at a furious pace." And a cadre of ecologists and conservation biologists has responded, vigorously promoting a new definition of nature: biodiversity--advocating it in Congress and on the Tonight Show; whispering it into the ears of foreign leaders; redefining the boundaries of science and politics, ethics and religion, nature and our ideas of nature. These scientists have infused the environmental movement with new focus and direction, but by engaging in such activities, they jeopardize the societal trust that allows them to be public spokespersons for nature in the first place. The Idea of Biodiversity analyzes what biodiversity represents to the biologists who operate in broader society on its behalf, drawing on in-depth interviews with the scientists most active today in the mission to preserve biodiversity, including Peter Raven, Thomas Lovejoy, Jane Lubchenco, and Paul Ehrlich. Takacs explores how and why these biologists shaped the concept of biodiversity and promoted it to society at large--examining their definitions of biodiversity; their opinions about spirituality and its role in scientific work; the notion of biodiversity as something of intrinsic value; and their views on biophilia, E. O. Wilson's idea that humans are genetically predisposed to love nature. Takacs also looks at the work of twentieth-century forerunners of today's conservation biologists--Aldo Leopold, Charles S. Elton, Rachel Carson, David Ehrenfeld--and points out theircontributions to the current debates. He takes readers to Costa Rica, where a group of scientists is using biodiversity to remake nature and society. And in an extended section, he profiles the thoughts and work of E. O. Wilson. "When I'm asked, 'should we save this species orthat species, or this place or that place?' the answer is always 'Yes!' with an exclamation point. Because it's obvious. And if you ask me to justify it, then I switch into a more cognitive consciousness and can start giving you reasons, economic reasons, aesthetic reasons. They're all dualistic, in a sense. But the feeling that underlies it is that 'yes!' And that 'yes!' comes out of the affirmation of being part of it all, being part of this whole evolutionary process. And agreeing with Arne Naess that each species, each entity, should be allowed to continue its evolution and to live out its destiny... just do its thing, as we say. Why not? And the 'why not?' is there's too many people."--Michael E. Soule, from an interview in The Idea of Biodiversity "An important contribution, a first distanced examination of a critical, modern topic by a scholarly, honest broker."--E. O. Wilson, Harvard University

Book Description
Despite its supreme importance and the threat of its global crash, biodiversity remains poorly understood both empirically and theoretically. This ambitious book presents a new, general neutral theory to explain the origin, maintenance, and loss of biodiversity in a biogeographic context. Until now biogeography (the study of the geographic distribution of species) and biodiversity (the study of species richness and relative species abundance) have had largely disjunct intellectual histories. In this book, Stephen Hubbell develops a formal mathematical theory that unifies these two fields. When a speciation process is incorporated into Robert H. MacArthur and Edward O. Wilson's now classical theory of island biogeography, the generalized theory predicts the existence of a universal, dimensionless biodiversity number. In the theory, this fundamental biodiversity number, together with the migration or dispersal rate, completely determines the steady-state distribution of species richness and relative species abundance on local to large geographic spatial scales and short-term to evolutionary time scales. Although neutral, Hubbell's theory is nevertheless able to generate many nonobvious, testable, and remarkably accurate quantitative predictions about biodiversity and biogeography. In many ways Hubbell's theory is the ecological analog to the neutral theory of genetic drift in genetics. The unified neutral theory of biogeography and biodiversity should stimulate research in new theoretical and empirical directions by ecologists, evolutionary biologists, and biogeographers.

Book Description
In the life sciences, there is wide-ranging debate about biodiversity. While nearly everyone is in favor of biodiversity and its conservation, methods for its assessment vary enormously. So what exactly is biodiversity? Most theoretical work on the subject assumes it has something to do with species richness—with the number of species in a particular region—but in reality, it is much more than that. Arguing that we cannot make rational decisions about what it is to be protected without knowing what biodiversity is, James Maclaurin and Kim Sterelny offer in What Is Biodiversity? a theoretical and conceptual exploration of the biological world and how diversity is valued. Here, Maclaurin and Sterelny explore not only the origins of the concept of biodiversity, but also how that concept has been shaped by ecology and more recently by conservation biology. They explain the different types of biodiversity important in evolutionary theory, developmental biology, ecology, morphology and taxonomy and conclude that biological heritage is rich in not just one biodiversity but many. Maclaurin and Sterelny also explore the case for the conservation of these biodiversities using option value theory, a tool borrowed from economics. An erudite, provocative, timely, and creative attempt to answer a fundamental question, What Is Biodiversity? will become a foundational text in the life sciences and studies thereof.

Book Description
The loss of the earth's biological diversity is widely recognized as a critical environmental problem. That loss is most severe in developing countries, where the conditions of human existence are most difficult. Conserving Biodiversity presents an agenda for research that can provide information to formulate policy and design conservation programs in the Third World. The book includes discussions of research needs in the biological sciences as well as economics and anthropology, areas of critical importance to conservation and sustainable development. Although specifically directed toward development agencies, non-governmental organizations, and decisionmakers in developing nations, this volume should be of interest to all who are involved in the conservation of biological diversity.

Book Description
"The book before you...carries the urgent warning that we are rapidly altering and destroying the environments that have fostered the diversity of life forms for more than a billion years." With those words, Edward O. Wilson opened the landmark volume Biodiversity (National Academy Press, 1988). Despite this and other such alarms, species continue to vanish at a rapid rate, taking with them their genetic legacy and potential benefits. Many disappear before they can even be identified. Biodiversity II is a renewed call for urgency. This volume updates readers on how much we already know and how much remains to be identified scientifically. It explores new strategies for quantifying, understanding, and protecting biodiversity, including: New approaches to the integration of electronic data, including a proposal for a U.S. National Biodiversity Information Center. Application of techniques developed in the human genome project to species identification and classification. The Gap Analysis Program of the National Biological Survey, which uses layered satellite, climatic, and biological data to assess distribution and better manage biodiversity. The significant contribution of museum collections to identifying and categorizing species, which is essential for understanding ecological function and for targeting organisms and regions at risk. The book describes our growing understanding of how megacenters of diversity (e.g., rainforest insects, coral reefs) are formed, maintained, and lost; what can be learned from mounting bird extinctions; and how conservation efforts for neotropical primates have fared. It also explores ecosystem restoration, sustainable development, and agricultural impact. Biodiversity II reinforces the idea that the conservation of our biological resources is within reach as long as we pool resources; better coordinate the efforts of existing institutionsâ€"museums, universities, and government agenciesâ€"already dedicated to this goal; and enhance support for research, collections, and training. This volume will be important to environmentalists, biologists, ecologists, educators, students, and concerned individuals.

Book Description
Biological diversity is considered one of today’s most urgent environmental concerns, yet the term was first coined only twenty-five years ago. Why did the concept of biological diversity so quickly capture public attention and emerge as a banner issue for the environmental movement? In this book, Timothy J. Farnham explores for the first time the historical roots of biological diversity, tracing the evolution of the term as well as the history of the conservation traditions that contributed to its rapid acceptance and popularity. Biological diversity is understood today as consisting of three components--species diversity, genetic diversity, and ecosystem diversity. Farnham finds that these three tiers coincided with three earlier, disparate conservation traditions that converged when the cause of preserving biological diversity was articulated. He tells the stories of these different historical foundations, recounts how the term came into the environmental lexicon, and shows how the evolution of the idea of biological diversity reflects an evolution of American attitudes toward the natural world.

Book Description
This open access book features essays written by philosophers, biologists, ecologists and conservation scientists facing the current biodiversity crisis. Despite increasing communication, accelerating policy and management responses, and notwithstanding improving ecosystem assessment and endangered species knowledge, conserving biodiversity continues to be more a concern than an accomplished task. Why is it so?The overexploitation of natural resources by our species is a frequently recognised factor, while the short-term economic interests of governments and stakeholders typically clash with the burdens that implementing conservation actions imply. But this is not the whole story. This book develops a different perspective on the problem by exploring the conceptual challenges and practical defiance posed by conserving biodiversity, namely: on the one hand, the difficulties in defining what biodiversity is and characterizing that “thing” to which the word ‘biodiversity’ refers to; on the other hand, the reasons why assessing biodiversity and putting in place effective conservation actions is arduous.
