Species diversity is an index that incorporates the number of species in an area and also their relative abundance. Since species diversity is central to a large amount of ecological theory, its accurate measurement is key to understanding community structure and dynamics. Consequently, during the course of evolution, species have always gone extinct; however, the rate of extinction has increased in recent decades by as much as one hundred fold, some owing to environmental impact, mainly due to human activities. The authors of this book present and review important data on biodiversity and species extinction.

This is a readable, informative and up-to-date account of the patterns and controls on biodiversity. The author describes major trends in species richness, along with uncertainties in current knowledge. The various possible explanations for past and present species patterns are discussed and explained in an even-handed and accessible way. The implications of global climate change and habitat loss are considered, along with current strategies for preserving what we have. This book examines the state of current understanding of species richness patterns and their explanations. As well as the present day world, it deals with diversification and extinction, in the conservation of species richness, and the difficulties of assessing how many species remain to be discovered. The scientifically compelling subject of vegetation-climate interaction is considered in depth. Written in an accessible style, the author offers an up-to-date, rigorous and yet eminently comprehensible overview of the ecology and biogeography of species richness. He departs from the often heavy approach of earlier texts, without sacrificing rigor and depth of information and analysis. Prefacing with the aims of the book, Chapter 1 opens with an explanation of latitudinal gradients, including a description of major features of the striking gradients in species richness, exceptions to the rule, explanations, major theories and field and experimental tests. The following chapter plumbs the depth of time, including the nature of the fossil record, broad timescale diversity patterns, ecosystem changes during mass extinctions and glaciations and their influence on species richness. Chapters 3 and 4 consider hotspots and local scale patterns in species richness while Chapter 5 looks at the limitations and uncertainties on current estimates of richness, the last frontiers of species diversity and the process of identifying new life forms. The last three chapters cover humans and extinctions in history and prehistory, current habitat and global change, including the greenhouse effect, and the race to preserve what we still have, including parks, gene banks and laws.

Despite acknowledgment that loss of living diversity is an international biological crisis, the ecological causes and consequences of extinction have not yet been widely addressed. In honor of Edward O. Wilson, winner of the 1993 International Prize for Biology, an international group of distinguished biologists bring ecological, evolutionary, and management perspectives to the issue of biodiversity. The roles of ecosystem processes, community structure and population dynamics are considered in this book. The goal, as Wilson writes in his introduction, is "to assemble concepts that unite the disciplines of systematics and ecology, and in so doing to create a sound scientific basis for the future management of biodiversity."

This important book for scientists and nonscientists alike calls attention to a most urgent global problem: the rapidly accelerating loss of plant and animal species to increasing human population pressure and the demands of economic development. Based on a major conference sponsored by the National Academy of Sciences and the Smithsonian Institution, Biodiversity creates a systematic framework for analyzing the problem and searching for possible solutions.

Maintaining the natural diversity of the countless species on Earth is of fundamental importance for the continued existence of life on this planet. Nevertheless, ecosystems are being destroyed, as the cultivation of land for agriculture, industry and housing is intensified and oceans continue to be exploited. The Demise of Diversity: Loss and Extinction deals with biodiversity on this planet and the vital importance of sustaining it—nothing less than the future of life on Earth.

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.

Darwin's Origin of Species and Dobzhansky's Genetics and the Origin of Species have been the cornerstones of modern evolutionary and population genetic theory for the past hundred years, but in the twenty-first century, biologists will face graver problems of extinction. In this collection, a team of leading biologists demonstrates why the burgeoning field of conservation biology must continue to rely on the insights of population genetics if we are to preserve the diversity of living species. Technological and theoretical developments throughout the 1990s have allowed for important new insights into how populations have evolved in response to past selection pressures, while providing a broad new understanding of the genetic structure of natural populations. The authors explore these advances and argue for the applicability of new genetic methods in conservation biology. The volume covers such topics as the reasons for extinctions, the best ways to measure biodiversity, and the benefits and drawbacks of policies like captive breeding. Genetics and the Extinction of Species is a rich source of information for biologists and policymakers who want to learn more about the host of tools, theories, and approaches available for conserving biodiversity. In addition to the editors, the contributors to the volume are William Amos, Rebecca Cann, Kathryn Rodriguez-Clark, Leslie Douglas, Leonard Freed, Paul Harvey, Kent Holsinger, Russell Lande, and Helen Steers.

Today the world faces the prospect of a devastating mass extinction, as species disappear at a rate that is many times faster than at any previous time in the earth's history. Finding ways to preserve the planet's rich variety of species is the challenge being taken up by conservation biologists, scientists who use their knowledge of ecology, genetics, and population dynamics to develop strategies for conserving biodiversity based on scientific principles. What really is the extent of biodiversity loss and how does one go about figuring it out? Why is biodiversity valuable for the earth and ourselves, and what can be done to conserve it? These are the questions that Andrew Dobson, a leading researcher and Princeton professor of ecology and epidemiology, addresses in his book. Beginning with discussions of species diversity, extinction rates, and how species endangerment is determined, Dobson goes on to discuss what is perhaps the book's most fascinating topic: the ins and outs of attempts to manage endangered species and the economics of different conservation strategies. The author describes the changes in animal populations before and after management attempts - from fish to whales, from the ivory trade in elephants to sales of rhino horns - and he analyzes the function of zoos and attempts to reintroduce species into the wild.
