The number of species found at a given point on the planet varies by orders of magnitude, yet large-scale gradients in biodiversity appear to follow some very general patterns. Little mechanistic theory has been formulated to explain the emergence of observed gradients of biodiversity both on land and in the oceans. Based on a comprehensive empirical synthesis of global patterns of species diversity and their drivers, A Theory of Global Biodiversity develops and applies a new theory that can predict such patterns from few underlying processes. The authors show that global patterns of biodiversity fall into four consistent categories, according to where species live: on land or in coastal, pelagic, and deep ocean habitats. The fact that most species groups, from bacteria to whales, appear to follow similar biogeographic patterns of richness within these habitats points toward some underlying structuring principles. Based on empirical analyses of environmental correlates across these habitats, the authors combine aspects of neutral, metabolic, and niche theory into one unifying framework. Applying it to model terrestrial and marine realms, the authors demonstrate that a relatively simple theory that incorporates temperature and community size as driving variables is able to explain divergent patterns of species richness at a global scale. Integrating ecological and evolutionary perspectives, A Theory of Global Biodiversity yields surprising insights into the fundamental mechanisms that shape the distribution of life on our planet.

The Unified Neutral Theory of Biodiversity and Biogeography available in PDF, EPUB and Kindle. 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.

The rate of extinction of biological species is greater today than at any time in the last 65 million years. Some predict that if this rate continues, two-thirds of all living species will disappear during the next century. Because reaching consensus on specific courses of action involves complex issues, any adequate response to this impending crisis must include coverage of many areas of inquiry and understanding. Protection of Global Biodiversity features essays by distinguished international experts who communicate with each other across disciplinary boundaries to address the challenge of formulating policies to protect biodiversity. Although the global community has recently adopted a Convention of Biological Diversity, the agreement sets forth only abstract goals. Contributors to this volume advance the Convention's initial steps by providing workable solutions that can be implemented regionally, nationally, and locally. The contributors--including natural, social, and political scientists; economists; lawyers; and environmentalists; and decisionmakers in business, agriculture, and government--have united to create a common discourse and to evaluate and propose strategies for halting this alarming loss of biodiversity. In recognizing the diverse aspects of this task--scientific, economic, institutional, moral, and legal--this book presents a new picture of emerging action. Contributors. S.
