Contents: Biodiversity Science: Definition, Scope and Constraints / Genetic Diversity / Species Diversity: Wild Taxa / Agrobiodiversity and Cultivated Taxa / Ecosystem Diversity / Values and Uses of Biodiversity / Loss of Biodiversity / Conservation of Biodiversity / Management of Plant Biodiversity / Biodiversity and Biotechnology / Biodiversity Prospecting and Indigenous Knowledge Systems / References / Glossary / Acronyms and Abbreviations / Subject Index / Author Index

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.

Biodiversity and its Significance deals with the various fundamental aspects of biodiversity, which have a direct and strong impact on human beings and their environment. It comprises 20 articles contributed by renowned experts in their areas. This pioneering book has been designed for the students and research scholars of Plant Sciences, Agricultural Science and Bioinformatics.

This book comprehensively describes essential research and projects on climate change and biodiversity. Moreover, it includes contributions on how to promote the climate agenda and biodiversity conservation at the local level. Climate change as a whole and global warming in particular are known to have a negative impact on biodiversity in three main ways. Firstly, increases in temperatures are detrimental to a number of organisms, especially those in sensitive habitats such as coral reefs and rainforests. Secondly, the pressures posed by a changing climate may lead to sets of responses in areas as varied as phenology, range and physiology of living organisms, often leading to changes in their lifecycles (especially but not only in reproduction), losses in productivity or even death. In some cases, the very survival of very sensitive species may be endangered. Thirdly, the impacts of climate change on biodiversity will be felt in the short term with regard to some species and ecosystems, but also in the medium and long term in many biomes. Indeed, if left unchecked, some of these impacts may be irreversible. Many individual governments, financial institutes and international donors are currently spending billions of dollars on projects addressing climate change and biodiversity, but with little coordination. Quite often, the emphasis is on adaptation efforts, with little emphasis on the connections between physio-ecological changes and the lifecycles and metabolisms of fauna and flora, or the influence of poor governance on biodiversity. As such, there is a recognized need to not only better understand the impacts of climate change on biodiversity, but to also identify, test and implement measures aimed at managing the many risks that climate change poses to fauna, flora and micro-organisms. In particular, the question of how to restore and protect ecosystems from the impact of climate change also has to be urgently addressed. This book was written to address this need. The respective papers explore matters related to the use of an ecosystem-based approach to increase local adaptation capacity, consider the significance of a protected areas network in preserving biodiversity in a changing northern European climate, and assess the impacts of climate change on specific species, including wild terrestrial animals. The book also presents a variety of case studies such as the Yellowstone to Yukon Conservation Initiative, the effects of climate change on the biodiversity of Aleppo pine forest in Senalba (Algeria), climate change and biodiversity response in the Niger Delta region, and the effects of forest fires on the biodiversity and the soil characteristics of tropical peatlands in Indonesia. This is a truly interdisciplinary publication, and will benefit all scholars, social movements, practitioners and members of governmental agencies engaged in research and/or executing projects on climate change and biodiversity around the world.

Biodiversity refers to the vast variety that is present in the flora and fauna of the earth's environment. Wildlife and forests are unevenly distributed around the earth and changes in environment as well as human activity can drastically alter the habits and habitat of both. This book on biodiversity, discusses the system of classification and management that has been practiced by experts in this field in the past few decades. This book is a complete source of knowledge on the present status of this important field. It traces the progress of this field and highlights some of its key concepts and applications and it elucidates the multidisciplinary aspects of biodiversity. This book is a vital tool for all researching or studying this field as it provides incredible insights into emerging trends and concepts.

The biota of the earth is being altered at an unprecedented rate. We are witnessing wholesale exchanges of organisms among geographic areas that were once totally biologically isolated. We are seeing massive changes in landscape use that are creating even more abundant succes sional patches, reductions in population sizes, and in the worst cases, losses of species. There are many reasons for concern about these trends. One is that we unfortunately do not know in detail the conse quences of these massive alterations in terms of how the biosphere as a whole operates or even, for that matter, the functioning of localized ecosystems. We do know that the biosphere interacts strongly with the atmospheric composition, contributing to potential climate change. We also know that changes in vegetative cover greatly influence the hydrology and biochemistry ofa site or region. Our knowledge is weak in important details, however. How are the many services that ecosystems provide to humanity altered by modifications of ecosystem composition? Stated in another way, what is the role of individual species in ecosystem function? We are observing the selective as well as wholesale alteration in the composition of ecosystems. Do these alterations matter in respect to how ecosystems operate and provide services? This book represents the initial probing of this central ques tion. It will be followed by other volumes in this series examining in depth the functional role of biodiversity in various ecosystems of the world.

View a collection of videos on Professor Wilson entitled "On the Relation of Science and the Humanities" "In the Amazon Basin the greatest violence sometimes begins as a flicker of light beyond the horizon. There in the perfect bowl of the night sky, untouched by light from any human source, a thunderstorm sends its premonitory signal and begins a slow journey to the observer, who thinks: the world is about to change." Watching from the edge of the Brazilian rain forest, witness to the sort of violence nature visits upon its creatures, Edward O. Wilson reflects on the crucible of evolution, and so begins his remarkable account of how the living world became diverse and how humans are destroying that diversity. Wilson, internationally regarded as the dean of biodiversity studies, conducts us on a tour through time, traces the processes that create new species in bursts of adaptive radiation, and points out the cataclysmic events that have disrupted evolution and diminished global diversity over the past 600 million years. The five enormous natural blows to the planet (such as meteorite strikes and climatic changes) required 10 to 100 million years of evolutionary repair. The sixth great spasm of extinction on earth--caused this time entirely by humans--may be the one that breaks the crucible of life. Wilson identifies this crisis in countless ecosystems around the globe: coral reefs, grasslands, rain forests, and other natural habitats. Drawing on a variety of examples such as the decline of bird populations in the United States, the extinction of many species of freshwater fish in Africa and Asia, and the rapid disappearance of flora and fauna as the rain forests are cut down, he poignantly describes the death throes of the living world's diversity--projected to decline as much as 20 percent by the year 2020. All evidence marshaled here resonates through Wilson's tightly reasoned call for a spirit of stewardship over the world's biological wealth. He makes a plea for specific actions that will enhance rather than diminish not just diversity but the quality of life on earth. Cutting through the tangle of environmental issues that often obscure the real concern, Wilson maintains that the era of confrontation between forces for the preservation of nature and those for economic development is over; he convincingly drives home the point that both aims can, and must, be integrated. Unparalleled in its range and depth, Wilson's masterwork is essential reading for those who care about preserving the world biological variety and ensuring our planet's health.
