Book Description
The conservation of biodiversity has profound implications for managing natural resources with the need for scientific information as a foundation for management decisions increasing dramatically. The_ intent of this book is to look beyond the theory of biodiversity to_ the principles, practices, and policies needed for its conservation. Its objectives are to provide the scientific basis for understanding biodiversity, document case examples of theory and concepts applied at differing scales, and examine policies that affect its conservation.

Book Description
An ideal text for students taking a course in landscape ecology. The book has been written by very well-known practitioners and pioneers in the new field of ecological analysis. Landscape ecology has emerged during the past two decades as a new and exciting level of ecological study. Environmental problems such as global climate change, land use change, habitat fragmentation and loss of biodiversity have required ecologists to expand their traditional spatial and temporal scales and the widespread availability of remote imagery, geographic information systems, and desk top computing has permitted the development of spatially explicit analyses. In this new text book this new field of landscape ecology is given the first fully integrated treatment suitable for the student. Throughout, the theoretical developments, modeling approaches and results, and empirical data are merged together, so as not to introduce barriers to the synthesis of the various approaches that constitute an effective ecological synthesis. The book also emphasizes selected topic areas in which landscape ecology has made the most contributions to our understanding of ecological processes, as well as identifying areas where its contributions have been limited. Each chapter features questions for discussion as well as recommended reading.

Book Description
Understanding how ecosystems are assembled -- how the species that make up a particular biological community arrive in an area, survive, and interact with other species -- is key to successfully restoring degraded ecosystems. Yet little attention has been paid to the idea of assembly rules in ecological restoration, in both the scientific literature and in on-the-ground restoration efforts. Assembly Rules and Restoration Ecology, edited by Vicky M. Temperton, Richard J. Hobbs, Tim Nuttle, and Stefan Halle, addresses that shortcoming, offering an introduction, overview, and synthesis of the potential role of assembly rules theory in restoration ecology. It brings together information and ideas relating to ecosystem assembly in a restoration context, and includes material from a wide geographic range and a variety of perspectives. Assembly Rules and Restoration Ecology contributes new knowledge and ideas to the subjects of assembly rules and restoration ecology and represents an important summary of the current status of an emerging field. It combines theoretical and practical aspects of restoration, making it a vital compendium of information and ideas for restoration ecologists, professionals, and practitioners.

Book Description
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.

Book Description
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.

Book Description
Is it possible to sustain biological diversity in managed forests? Or should biodiversity strategies focus solely on reserves and protected areas? A group of well-known scientists specializing in forestry issues apply scientific expertise to the "hot politics" of the forestry debate and present compelling evidence as to the sustainability of biological diversity in managed forests.

Book Description
Although diversity is one of the central themes of ecology there is considerable disagreement ab out how it should be measured. I first encountered this problem 10 ycars ago whcn I started my research career and spent a long time pouring ovcr the literature in order to find the most useful techniques. The intervening decade has seen a further increasc in the number ofpapers devoted to the topic of ecological diversity but has led to no consensus on how it should be measured. My aim in writing this book is therefore to provide a practical guide to ecological diversity and its measurement. In a quantitative subject such as the measurement of diversity it is inevitable that some mathematics are involved, but at all times these are kept as simple as possible, and the emphasis is constantly on ecological reality and practical application. I hope that others ente ring thc fascinating ficld of ecological diversity will find it hclpful. This book grew out of my work in The School of Biological and Environmental Studies at the New University ofUlster, Coleraine, Northern Ircland. I am indebted to all the ecologists there for pro vi ding a stimulating atmosphere. Foremost among these were Amyan Macfadyen and Palmer Newbould. A number of the figures and tables in the book are based on data collected in Northern Irish woodlands.
