Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Unified Neutral Theory of Biodiversity and Biogeography written by Stephen P. Hubbell and published by Princeton University Press. This book was released on 2011-06-27 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite its supreme importance and the threat of its global crash, biodiversity remains poorly understood both empirically and theoretically. This ambitious book presents a new, general neutral theory to explain the origin, maintenance, and loss of biodiversity in a biogeographic context. Until now biogeography (the study of the geographic distribution of species) and biodiversity (the study of species richness and relative species abundance) have had largely disjunct intellectual histories. In this book, Stephen Hubbell develops a formal mathematical theory that unifies these two fields. When a speciation process is incorporated into Robert H. MacArthur and Edward O. Wilson's now classical theory of island biogeography, the generalized theory predicts the existence of a universal, dimensionless biodiversity number. In the theory, this fundamental biodiversity number, together with the migration or dispersal rate, completely determines the steady-state distribution of species richness and relative species abundance on local to large geographic spatial scales and short-term to evolutionary time scales. Although neutral, Hubbell's theory is nevertheless able to generate many nonobvious, testable, and remarkably accurate quantitative predictions about biodiversity and biogeography. In many ways Hubbell's theory is the ecological analog to the neutral theory of genetic drift in genetics. The unified neutral theory of biogeography and biodiversity should stimulate research in new theoretical and empirical directions by ecologists, evolutionary biologists, and biogeographers.

Download or read book Protection of Global Biodiversity written by Lakshman D. Guruswamy and published by . This book was released on 1998 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Marine Biodiversity Climatic Variability and Global Change written by Grégory Beaugrand and published by Routledge. This book was released on 2014-11-28 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity loss in terrestrial environments associated with human activities has been appreciated as a major issue for some years now. What is less well documented is the effect of such activities, including climate change, on marine biodiversity. This pioneering book is the first to address this important but neglected topic, which is likely to be the key challenge for marine scientists in the near future. Using a multidisciplinary and a holistic approach, the book reveals how climatic variability controls biodiversity at time scales ranging from synoptic meteorological events to millions of years and at spatial scales ranging from local sites to the whole ocean. It shows how global change, including anthropogenic climate change, ocean acidification and more direct human influences such as exploitation, pollution and eutrophication may alter biodiversity, ecosystem functioning and regulating and provisioning services. The author proposes a theory termed the 'macroecological theory on the arrangement of life', which explains how biodiversity is organized and how it responds to climatic variability and anthropogenic climate change. The book concludes with recommendations for further research and theoretical development to identify oceanic areas in need of observation and gaps in current scientific knowledge. Many references and comparisons with the terrestrial realm are included in all chapters to better understand the universality of the relationships between biodiversity, climate and the environment. The book will serve as a textbook for all students and researchers of marine science and environmental change, but will also be accessible to the more general reader.

Download or read book Biological Diversity written by Michael A. Huston and published by Cambridge University Press. This book was released on 1994-09-15 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Natural Capital written by Peter Kareiva and published by Oxford University Press. This book was released on 2011-04-07 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2005, The Millennium Ecosystem Assessment (MA) provided the first global assessment of the world's ecosystems and ecosystem services. It concluded that recent trends in ecosystem change threatened human wellbeing due to declining ecosystem services. This bleak prophecy has galvanized conservation organizations, ecologists, and economists to work toward rigorous valuations of ecosystem services at a spatial scale and with a resolution that can inform public policy. The editors have assembled the world's leading scientists in the fields of conservation, policy analysis, and resource economics to provide the most intensive and best technical analyses of ecosystem services to date. A key idea that guides the science is that the modelling and valuation approaches being developed should use data that are readily available around the world. In addition, the book documents a toolbox of ecosystem service mapping, modeling, and valuation models that both The Nature Conservancy and the World Wide Fund for Nature (WWF) are beginning to apply around the world as they transform conservation from a biodiversity only to a people and ecosystem services agenda. The book addresses land, freshwater, and marine systems at a variety of spatial scales and includes discussion of how to treat both climate change and cultural values when examining tradeoffs among ecosystem services.

Download or read book Governing Global Biodiversity written by Philippe G. Le Prestre and published by Routledge. This book was released on 2017-05-15 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predictions about the success of the Convention on Biological Diversity (CBD) are pessimistic. It has now become commonplace to bemoan the scope, ambition, and deeply political nature of a convention that addresses issues ranging from ecosystems protection to the exploitation of genetic resources, from conservation to justice, and from commerce to scientific knowledge. Ten years after its adoption, how can we assess the difference that the CBD has made? Is it in danger of collapsing under its own weight or is it building the foundations of new patterns of relations between societies and nature? What achievements can we record and what challenges does it face? In this book, which is unique in its scope, diversity and the wealth of information it contains, contributors from a variety of academic disciplines tackle an issue of enduring importance to the protection of biodiversity and enhance our understanding of humanity's capacity to reconcile its various aspirations and halt the destructive path upon which it is set.

Download or read book The Politics of Knowledge and Global Biodiversity written by Alice B.M. Vadrot and published by Routledge. This book was released on 2014-04-24 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The establishment of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) points to the crucial role attributed to science and knowledge for the successful implementation of biodiversity politics by both scientists and policy-makers. With the increased importance of biodiversity in international politics, and in part inspired by the success the Intergovernmental Panel on Climate Change (IPCC) has had in raising awareness of global warming, the call for an ‘IPCC for Biodiversity’ was successful. The Politics of Knowledge and Global Biodiversity gives a full overview of the process of its implementation as finalised in 2013 and proposes an innovative conceptual framework that puts this specific case into a more general perspective of international politics and relations. It provides a detailed empirical analysis of the knowledge politics associated with the establishment of IPBES and its conceptual framework and methodological approach is grounded in a theoretical perspective. This pioneering work is the first to examine IPBES in this way and is essential reading for researchers and scholars of International Relations, Environmental and Biodiversity Politics, Science-Policy Interfaces and Global Environmental Governance. It will also be of interest to political scientists and social scientists.

Download or read book Feminist Theory and International Law written by Emily Jones and published by Taylor & Francis. This book was released on 2023-01-31 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feminist approaches to international law have been mischaracterised by the mainstream of the discipline as being a niche field that pertains only to women’s lived experiences and their participation in decision-making processes. Exemplifying how feminist approaches can be used to analyse all areas of international law, this book applies posthuman feminist theory to examine the regulation of new and emerging military technologies, international environmental law and the conceptualisation of the sovereign state and other modes of legal personality in international law. Noting that most posthuman scholarship to date is primarily theoretical, this book also contributes to the field of posthumanism through its application of posthuman feminism to international law, working to bridge the theory and practice divide by using posthuman feminism to design and call for legal change. This interdisciplinary book draws on an array of fields, including philosophy, queer and feminist theories, postcolonial and critical race theories, computer science, critical disability studies, science and technology studies, marine biology, cultural and media studies, Indigenous onto-epistemologies, critical legal theory, political science and beyond to provide a holistic analysis of international law and its inclusions and exclusions. This interdisciplinary book will appeal to students and scholars with interests in legal, feminist and posthuman theory, as well as those concerned with the contemporary challenges faced by international law.

Download or read book What s So Good About Biodiversity written by Donald S. Maier and published by Springer. This book was released on 2012-05-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a deluge of material on biodiversity, starting from a trickle back in the mid-1980's. However, this book is entirely unique in its treatment of the topic. It is unique in its meticulously crafted, scientifically informed, philosophical examination of the norms and values that are at the heart of discussions about biodiversity. And it is unique in its point of view, which is the first to comprehensively challenge prevailing views about biodiversity and its value. According to those dominant views, biodiversity is an extremely good thing – so good that it has become the emblem of natural value. The book's broader purpose is to use biodiversity as a lens through which to view the nature of natural value. It first examines, on their own terms, the arguments for why biodiversity is supposed to be a good thing. This discussion cuts a very broad and detailed swath through the scientific, economic, and environmental literature. It finds all these arguments to be seriously wanting. Worse, these arguments appear to have consequences that should dismay and perplex most environmentalists. The book then turns to a deeper analysis of these failures and suggests that they result from posing value questions from within a framework that is inappropriate for nature's value. It concludes with a novel suggestion for framing natural value. This new proposal avoids the pitfalls of the ones that prevail in the promotion of biodiversity. And it exposes the goals of conservation biology, restoration biology, and the world's largest conservation organizations as badly ill-conceived.

Download or read book How Life Increases Biodiversity written by David Seaborg and published by CRC Press. This book was released on 2021-09-09 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book argues that organisms and their interactions create and maximize biodiversity. The evidence for this autocatalytic hypothesis has been collated and integrated into this provocative argument. Natural selection favors the increase of biodiversity. Organisms can be causative agents contributing to major macroevolutionary transitions. Species tend to have a net positive effect on biodiversity. All species are ecosystem engineers. Mutualism and commensalism are common and fundamental, and these coevolved interspecific interactions frequently generate enormous increases in biodiversity. Competition generally does not decrease biodiversity, and often leads to evolutionary innovation. Plants are ecosystem engineers that have made Earth more favorable to life and increased diversity in many ways. Herbivores and predators increase the diversity of the species they consume, and are necessary for ecosystem stability. Decomposers are essential to ecosystem health. All these examples illustrate the focus of this book – that organisms and their interactions stimulate biodiversity, and ecosystems maximize it. Key Features • Describes a hypothesis that life itself generates higher biodiversity • Suggests a highly modified version of the established paradigm in population biology and evolution • Asserts that all species are ecosystem engineers with a net positive effect on biodiversity and their ecosystems • Suggests that mutualism and commensalism are the rule • Presents a novel view likely to elicit deeper discussions of biodiversity Related Titles Dewdney, A.
