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.

Book Description
A pioneering work, Species Diversity in Ecological Communities looks at biodiversity in its broadest geographical and historical contexts. For many decades, ecologists have studied only small areas over short time spans in the belief that diversity is regulated by local ecological interactions. However, to understand fully how communities come to have the diversity they do, and to properly address urgent conservation problems, scientists must consider global patterns of species richness and the historical events that shape both regional and local communities. The authors use new theoretical developments, analyses, and case studies to explore the large-scale mechanisms that generate and maintain diversity. Case studies of various regions and organisms consider how local and regional processes interact to determine patterns of species richness. The contributors emphasize the fact that ecological processes acting quickly on a local scale do not erase the effects of regional and historical events that occur more slowly and less frequently. This book compels scientists to rethink the foundations of community ecology and sets the stage for further research using comparative, experimental, geographical, and historical data.

Book Description
Increased throughput of carbon-based fossil energy, the destruction of Earth's forests, and other land use changes have resulted in ever higher levels of waste in the form of greenhouse gases-as well as a diminished capacity of the planet to absorb and store those wastes. This means that to avoid catastrophic global warming and maintain the habitab

Book Description
This book draws on world-wide experiences and valuable lessons to highlight community-ecosystem interactions and the role of traditional knowledge in sustaining biocultural resources through community-based adaptations. The book targets different audiences including researchers working on human-environment interactions and climate adaptation practices, biodiversity conservators, non-government organizations and policy makers involved in revitalizing traditional foods and community-based conservation and adaptation in diverse ecosystems. This volume is also a source book for educators advocating for and collaborating with indigenous and local peoples to promote location-specific adaptations to overcome the impacts of multiple biotic and abiotic stresses.

Book Description
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

Book Description
Ecologists have always believed, at least to a certain extent, that physiological mechanisms serve to underpin ecological patterns. However, their importance has traditionally been at best underestimated and at worst ignored, with physiological variation being dismissed as either an irrelevance or as random noise/error. Spicer and Gaston make a convincing argument that the precise physiology does matter! In contrast to previous works which have attempted to integrate ecology and physiology, Physiological Diversity adopts a completely different and more controversial approach in tackling the physiology first before moving on to consider the implications for ecology. This is timely given the recent and considerable interest in the mechanisms underlying ecological patterns. Indeed, many of these mechanisms are physiological. This textbook provides a contemporary summary of physiological diversity as it occurs at different hierarchical levels (individual, population, species etc.), and the implications of such diversity for ecology and, by implication, evolution. It reviews what is known of physiological diversity and in doing so exposes the reader to all the key works in the field. It also portrays many of these studies in a completely new light, thereby serving as an agenda for, and impetus to, the future study of physiological variation. Physiological Diversity will be of relevance to senior undergraduates, postgraduates and professional researchers in the fields of ecology, ecological physiology, ecotoxicology, environmental biology and conservation. The book spans both terrestrial and marine systems.

Book Description
Our world is filled with unseen wonders - the most phenomenal of which is the often hidden beauty of the diversity that surrounds us. Apart from the beauty diversity brings to our lives, it is also absolutely necessary to the sustainability of life itself. The importance of diversity is overlooked in the social realm, yet decisions made in that realm affect all of society for generations. Planners tend to ignore ecological diversity because they don't understand it. Ecological Diversity in Sustainable Development: The Vital and Forgotten Dimension makes that clear. The author tackles this difficult problem: how are we to maintain sustainable diversity in the Earth's ecosystems and our cultural systems? He provides examples of how natural and cultural diversity have been reduced by altering the linkages between climate, soil, water, air, forests, animals, and people. The book is divided into three parts. Part one examines diversity as it is found in nature, part two considers how culture affects diversity through its evolution, and part three explores the diversity of Nature as seen through culture in an attempt to guide culture toward social/environmental sustainability. Anyone who is interested in the quality of life on Earth will want this book. Maser writes in easy-to-read lucid prose, providing a holistic overview of environmental issues that 21st century decision makers must address in shaping our destiny.

Book Description
One of the central research themes in ecology is evaluating the extent to which biological richness is necessary to sustain the Earth's system and the functioning of individual ecosystems. In this volume, for the first time, the relationship between biodiversity and ecosystem processes in forests is thoroughly explored. The text examines the multiple effects of tree diversity on productivity and growth, biogeochemical cycles, animals, pests, and disturbances. Further, the importance of diversity at different scales, ranging from stand management to global issues, is considered. The authors provide both extensive reviews of the existing literature and own datasets. The volume is ideally suited for researchers and practitioners involved in ecosystem management and the sustainable use of forest resources.
