The key to preserving and managing biodiversity is understanding which processes are important at different scales, and how changes affect different components of biodiversity. In this book, existing theories on diversity are synthesised into a logical framework. Global and landscape-scale patterns of biodiversity are described in the first section. In the second, the spatial and temporal dynamics of diversity are emphasised. The third section develops an integrated set of mechanistic explanations for diversity patterns at the levels of population, community, ecosystem and landscape. Finally, case studies examine diversity patterns in marine and terrestrial ecosystems and the effects of biological invasions. The book concludes with a discussion of the economics of preserving biological diversity. This book will interest research workers and students of ecology, biology and conservation.

This accessible and timely book provides a comprehensive overview of how to measure biodiversity. The book highlights new developments, including innovative approaches to measuring taxonomic distinctness and estimating species richness, and evaluates these alongside traditional methods such as species abundance distributions, and diversity and evenness statistics. Helps the reader quantify and interpret patterns of ecological diversity, focusing on the measurement and estimation of species richness and abundance. Explores the concept of ecological diversity, bringing new perspectives to a field beset by contradictory views and advice. Discussion spans issues such as the meaning of community in the context of ecological diversity, scales of diversity and distribution of diversity among taxa Highlights advances in measurement paying particular attention to new techniques such as species richness estimation, application of measures of diversity to conservation and environmental management and addressing sampling issues Includes worked examples of key methods in helping people to understand the techniques and use available computer packages more effectively

This book provides an up to date review of the methods of measuring and assessing biological diversity, together with their application.

Oceanic islands represent a set of systems in which biological diversity varies as a consequence of remoteness or size, not environment; they are also generally simpler than continental ecosystems. Islands therefore provide an opportunity to determine the direct effects of biological diversity on ecosystem function. The volume addresses the components of biological diversity on islands and their patterns of variation; the modern threats to the maintenance of biological diversity on islands; the consequences of island biology and its modification by humanity regarding aspects of ecosystem function; the global implications of islands for conservation; and how islands can help one to understand the processes inducing changes throughout the world.

At the Rio Earth Summit in 1992, the nations of the world adopted the convention on Biological Diversity. Since then, over 160 countries have ratified the Convention, three Conferences of the Parties have taken place and a permanent secretariat has been established. Despite this, there remains a lot of uncertainty and even more controversy about what the Convention was intended to accomplish and how it was to do so. This book, published in association with the IUCN - The World Conservation Union, sets out to answer some of these questions by recounting the history of the movements leading up to the Convention, but especially by analysing the forces giving rise to the problem. It provides a specific set of policy prescriptions intended to facilitate the development of institutions and obligations within the international community which will give real effect to the aspirations of the Convention, and the ensure that it has some real effect at ground level. The author begins with an overview of the issues and then develops the basic nature of the problems within a bio-economic framework. He highlights the gaps in the Convention which remain to be filled, offers detailed explanations of the concepts involved and describes the nature of the solutions required. Thus he sets out a detailed plan for global action in support of an effective international convention for the conservation of biological diversity. The book is an excellent introduction to a very topical debate, and a valuable reference point for conservationists, policy makers and students of development studies, environmental studies, environmental policy and conservation biology.

The goal of this transdisciplinary book is to identify the problems and challenges facing implementation of the Convention on Biological Diversity (CBD) - from the global, regional and local points of view. The valuation and conservation of biodiversity are critical first steps necessary for the adequate protection of the environment. The authors give insights into the the influences the CBD exerts, and current trends in the field.

The title provides an overview of the current knowledge about the diversity of the living world and the various problems associated with its conservation and sustainable use. Covering both the fundamentals of the subject, along with the latest research, Biodiversity presents key conservation issues within a framework of global case studies. Starting with a summary of the concept of biodiversity, the text then explores such subjects as species richness, ecological systems, the consequences of human activities, diversity and human health, genetic resources, biotechnology and conservation. Comprehensive introduction to key issues surrounding the study of biodiversity. Extensive bibliography and references to numerous relevant websites. Introduces current research in the field within a framework of useful case studies.

Catherine Potvin, Margaret Kraenzel, and Gilles Seutin asked scientists from developing countries to summarize their experiences of international collaboration and to suggest attitudes and practices that would lead to more fruitful exchanges with northern scientists. They also asked scholars to provide an analytical framework in which these issues could be discussed and to identify possible solutions to questions such as: What are the responsibilities of first world scientists involved in conservation actions in developing countries? How can biologists work toward the protection of biodiversity while being respectful of the human desire for a better future? The resulting papers analyse specific situations encountered in countries such as Democratic Republic of Congo, Madagascar, India, and Panama and discuss the philosophical basis for environmental research. They also examine the work of two institutions whose projects in developing countries have been particularly effective through outreach and attention to local values and needs and who propose a pluralistic view of conservation biology ethics. Protecting Biological Diversity seeks to encourage students and professionals involved in conservation projects to adopt culturally sensitive attitudes that will lead to greater effectiveness and efficiency in conservation and greater respect for the differences of others.
