This book provides a first synthetic view of an emerging area of ecology and biogeography, linking individual- and population-level processes to geographic distributions and biodiversity patterns. Problems in evolutionary ecology, macroecology, and biogeography are illuminated by this integrative view. The book focuses on correlative approaches known as ecological niche modeling, species distribution modeling, or habitat suitability modeling, which use associations between known occurrences of species and environmental variables to identify environmental conditions under which populations can be maintained. The spatial distribution of environments suitable for the species can then be estimated: a potential distribution for the species. This approach has broad applicability to ecology, evolution, biogeography, and conservation biology, as well as to understanding the geographic potential of invasive species and infectious diseases, and the biological implications of climate change. The authors lay out conceptual foundations and general principles for understanding and interpreting species distributions with respect to geography and environment. Focus is on development of niche models. While serving as a guide for students and researchers, the book also provides a theoretical framework to support future progress in the field.
Biodiversity conservation and sustainable use of natural resources has remained one of the key challenges for development agencies and concerned stakeholders for decades together. The huge threat of climate change has only added to this complexity. In this context, the present book Biodiversity, Community, and Climate Change is designed to help in guiding the various principles of biodiversity conservation, effects of climate change and role of communities at various levels and landscapes. A total of 19 chapters are covered in this book and they encompass a wide range of topics including tools of biodiversity assessment ranging from conventional ecological and social survey methods to the use of latest technology such as Geographical Information System (GIS) and remote sensing. It includes: a description of biodiversity conservation with focus on the status of biodiversity from lower to higher flora and fauna; an assessment of evaluation of impacts of allelopathic compounds on growth of native plant species; significant emphasis on the usefulness of geospatial techniques for monitoring urban ecosystem and biodiversity; specific focus on community, livelihood, and management of biodiversity; and an analysis of participatory conservation and forest management case studies to further strengthen conservation approaches. It focuses on the vital importance of community forestry, agriculture sector and biodiversity conservation in addressing the threats of climate change.
Martin A. Hajer's original study examines the nature of contemporary environmental politics, analysing the emergence and sustenance of institutional perceptions of environmental problems.
From famed zoologist Anthony Sinclair, an account of his decades-long quest to understand one of Earth's most spectacular ecosystems With its rich biodiversity, astounding wildlife, and breathtaking animal migrations, Serengeti is like no other ecosystem on the planet. A Place like No Other is Anthony Sinclair's firsthand account of how he and other scientists discovered the biological principles that regulate life in Serengeti and how they rule all of the natural world. When Sinclair first began studying this spectacular ecosystem in 1965, a host of questions confronted him. What environmental features make its annual migration possible? What determines the size of animal populations and the stunning diversity of species? What factors enable Serengeti to endure over time? In the five decades that followed, Sinclair and others sought answers. What they learned is that seven principles of regulation govern all natural processes in the Serengeti ecosystem. Sinclair shows how these principles can help us to understand and overcome the challenges facing Serengeti today, and how they can be used to repair damaged habitats throughout the world. Blending vivid storytelling with invaluable scientific insights from Sinclair's pioneering fieldwork in Africa, A Place like No Other reveals how Serengeti holds timely lessons for the restoration and conservation of our vital ecosystems.
The species-area relationship (SAR) describes a range of related phenomena that are fundamental to the study of biogeography, macroecology and community ecology. While the subject of ongoing debate for a century, surprisingly, no previous book has focused specifically on the SAR. This volume addresses this shortfall by providing a synthesis of the development of SAR typologies and theory, as well as empirical research and application to biodiversity conservation problems. It also includes a compilation of recent advances in SAR research, comprising novel SAR-related theories and findings from the leading authors in the field. The chapters feature specific knowledge relating to terrestrial, marine and freshwater realms, ensuring a comprehensive volume relevant to a wide range of fields, with a mix of review and novel material and with clear recommendations for further research and application.
The field of biocultural diversity is emerging as a dynamic, integrative approach to understanding the links between nature and culture and the interrelationships between humans and the environment at scales from the global to the local. Its multifaceted contributions have ranged from theoretical elaborations, to mappings of the overlapping distributions of biological and cultural diversity, to the development of indicators as tools to measure, assess, and monitor the state and trends of biocultural diversity, to on-the-ground implementation in field projects. This book is a unique compendium and analysis of projects from all around the world that take an integrated biocultural approach to sustaining cultures and biodiversity. The 45 projects reviewed exemplify a new focus in conservation: this is based on the emerging realization that protecting and restoring biodiversity and maintaining and revitalizing cultural diversity and cultural vitality are intimately, indeed inextricably, interrelated.

This book provides an introduction to the role of diversity in complex adaptive systems. A complex system--such as an economy or a tropical ecosystem--consists of interacting adaptive entities that produce dynamic patterns and structures. Diversity plays a different role in a complex system than it does in an equilibrium system, where it often merely produces variation around the mean for performance measures. In complex adaptive systems, diversity makes fundamental contributions to system performance. Scott Page gives a concise primer on how diversity happens, how it is maintained, and how it affects complex systems. He explains how diversity underpins system level robustness, allowing for multiple responses to external shocks and internal adaptations; how it provides the seeds for large events by creating outliers that fuel tipping points; and how it drives novelty and innovation. Page looks at the different kinds of diversity--variations within and across types, and distinct community compositions and interaction structures--and covers the evolution of diversity within complex systems and the factors that determine the amount of maintained diversity within a system.Provides a concise and accessible introduction Shows how diversity underpins robustness and fuels tipping points Covers all types of diversity The essential primer on diversity in complex adaptive systems
Protected areas spearhead our response to the rapidly accelerating biodiversity crisis. However, while the number of protected areas has been growing rapidly over the past 20 years, the extent to which the world s protected areas are effectively conserving species, ecosystems, and ecosystem services is poorly understood. * Highlights new techniques for better management and monitoring of protected areas * Sets guidelines for the decision making processes involved in setting up and maintaining protected areas * Fully international in scope and covering all ecosystems and biomes
Home Gardens for Improved Food Security and Livelihoods demonstrates how home gardens hold particular significance for resource-poor and marginalized communities in developing countries, and how they offer a versatile strategy toward building local and more resilient food systems. With food and nutritional security being a major global challenge, there is an urgent need to find innovative ways to increase food production and diversify food sources while increasing income-generating opportunities for communities faced with hunger and poverty. This book shows that when implemented properly, home gardens can become just such an innovative solution, as well as an integral part of sustainable food security programs. It provides a conceptual overview of social, economic, environmental and nutritional issues related to home gardening in diverse contexts, including gender issues and biodiversity conservation, and presents case studies from Africa, Asia and Latin America highlighting home gardening experiences and initiatives. The volume concludes with a synthesis of key lessons learned and ways forward for further enhancing home gardens for sustainable food security and development. This book will be a useful read for students and scholars working on local food systems, food security, sustainable development and more broadly development strategy.
North east India is a global biodiversity hotspot but a quite understudied area. Forest loss has always been problematic in the area. Using Landsat satellite data from three periods (70s, 80s/90s and 2010s), forest loss is assessed in sample protected areas and other sites in the study area, processing is undertaken using image processing and standard GIS tools. The landscape metrics of selected sites are assessed using the widely used program FRAGSTATS. Drivers of forest loss are central in the discussion of the study.
Ecosystems today are dynamic and complex, leaving conservationists faced with the paradox of conserving moving targets. New approaches to conservation are now required that aim to conserve ecological function and process, rather than attempt to protect static snapshots of biodiversity. To do this effectively, long-term information on ecosystem variability and resilience is needed. While there is a wealth of such information in palaeoecology, archaeology, and historical ecology, it remains an underused resource by conservation ecologists. In bringing together the disciplines of neo- and palaeoecology and integrating them with conservation biology, this novel text illustrates how an understanding of long-term change in ecosystems can in turn inform and influence their conservation and management in the Anthropocene. By looking at the history of traditional management, climate change, disturbance, and land-use, the book describes how a long-term perspective on landscape change can inform current and pressing conservation questions such as whether elephants should be culled, how best to manage fire, and whether ecosystems can or should be "re-wilded" Biodiversity Conservation and Environmental Change is suitable for senior undergraduate and post-graduate students in conservation ecology, palaeoecology, biodiversity conservation, landscape ecology, environmental change and natural resource management. It will also be of relevance and use to a global market of conservation practitioners, researchers, educators and policy-makers.
Competition between species arises when two or more species share at least some of the same limited resources. It is likely to affect all species, as well as many higher-level aspects of community and ecosystem dynamics. Interspecific competition shares many of the same features as density dependence (intraspecific competition) and evolution (competition between genotypes). In spite of this, a robust theoretical framework is not yet in place to develop a more coherent understanding of this important interaction. Despite its prominence in the ecological literature, the theory seems to have lost direction in recent decades, with many synthetic papers promoting outdated ideas, failing to use resource-based models, and having little utility in applied fields such as conservation and environmental management. Competition theory has done little to incorporate new findings regarding consumer-resource interactions in the context of larger food webs containing behaviourally or evolutionarily adapting components. Overly simple models and methods of analysis continue to be influential. Competition Theory in Ecology represents a timely opportunity to address these shortcomings and suggests a more useful approach to modelling that can provide a basis for future models that have greater predictive ability in both ecology and evolution. The book concludes with some broader observations on the lack of agreement on general principles to use in constructing mathematical models to help understand ecological systems. It argues that a more open discussion and debate of the underlying structure of ecological theory is now urgently required to move the field forward.
'Inspiring. [...] Crammed with lively interviews and grounded examples' Ashish Kothari, founder of Kalpavriksh Permaculture is an environmental movement that makes us reevaluate what it means to be sustainable. Through innovative agriculture and settlement design, the movement creates new communities that are harmonious with nature. It has grown from humble origins on a farm in 1970s Australia and flourished into a worldwide movement that confronts industrial capitalism. The Politics of Permaculture is one of the first books to unpack the theory and practice of this social movement that looks to challenge the status quo. Drawing upon the rich seam of publications and online communities from the movement as well as extensive interviews with permaculture practitioners and organisations from around the world, Leahy explains the ways permaculture is understood and practiced in different contexts. In the face of extreme environmental degradation and catastrophic climate change, we urgently need a new way of living.
This book explores the epistemological and ethical issues at the foundations of environmental philosophy, emphasising the conservation of biodiversity. Sahota Sarkar criticises attempts to attribute intrinsic value to nature and defends an anthropocentric position on biodiversity conservation based on an untraditional concept of transformative value. Unlike other studies in the field of environmental philosophy, this book is as much concerned with epistemological issues as with environmental ethics. It covers a broad range of topics, including problems of explanation and prediction in traditional ecology and how individual-based models and Geographic Information Systems (GIS) technology is transforming ecology. Introducing a brief history of conservation biology, Sarkar analyses the consensus framework for conservation planning through adaptive management. He concludes with a discussion of directions for theoretical research in conservation biology and environmental philosophy.
The badgers of Wytham Woods (Oxford, UK) have been studied continuously and intensively by David Macdonald for almost 50 years (25 of them with his former student and co-author Chris Newman), generating a wealth of data pertaining to every facet of their ecology and evolution. Through a mix of accessible, highly readable prose and cutting-edge science, the authors weave a riveting scientific story of the lives of these intriguing creatures, highlighting the insights offered to science more broadly through badgers as a model system. They provide a paradigm - from population down to molecule - for a deeper understanding of mammalian behaviour, ecology, epidemiology, evolutionary biology, and conservation. The real value of this long-term study is particularly apparent with current and globally relevant challenges such as climate change, disease epidemics, and senescence. This unique dataset enables us to examine these issues in a context that only a half-century experiment can reveal. The Badgers of Wytham Woods will appeal to a broad audience of professional academics (especially carnivore and mammalian biologists), researchers and students at all levels, governmental and non-governmental wildlife bodies, and to the natural historian fascinated by wild animals and the remarkable processes of nature they exemplify.
The function of scientific research is promoting the understanding of the world around us. In theory, anyway, the more we learn, the more potential we have of making our lives better. Thus, we have seen research in electronics provide us with computers, research in chemistry provide us with all manner of synthetics, and research in agriculture provide us with more food. Periodically, scientific research uncovers something that makes some of us uncomfortable. The discovery of the link between smoking and lung cancer and heart disease was not received well by the tobacco industry, and the link between global climate change and fossil fuel use has not been well received by the petroleum industry, to cite just two examples. Usually the response of those whose world has been disrupted by science is denial, often followed by attack on or ridicule of the science that has challenged them. In the long term, however, science usually turns out to be correct.
The habitats of most species have been fragmented by human actions, isolating small populations that consequently develop genetic problems. Millions of small, isolated, fragmented populations are likely suffering from inbreeding depression and loss of genetic diversity, greatly increasing their risk of extinction. Crossing between populations is required to reverse these effects, but managers rarely do so. A key reason for such inaction is that managers are often advised to manage populations in isolation whenever molecular genetic methods indicate genetic differences among them. Following this advice will often doom small populations to extinction when the habitat fragmentation and genetic differences were caused by human activities. A paradigm shift is required whereby evidence of genetic differentiation among populations is a trigger to ask whether any populations are suffering genetic problems, and if so, whether they can be rescued by augmenting gene flow. Consequently, there is now an urgent need for an authoritative practical guide to facilitate this paradigm shift in genetic management of fragmented populations.

Although of high abundance, diversity and ecological importance, meiofauna is little covered by relevant scientific media. How can this negligence be overcome? The present treatise highlights promising meiofauna research fields, selected both from basic and applied science, as well as new methods that could strengthen the potential of meiobenthology. Selected recent meiofauna studies, often supported by rapidly advancing gene-based methods, underline the relevance and potential of meiobenthology revealing characteristics and harassments of ecosystems, not the least in extreme habitats. Also in the more classical domains such as taxonomy and phylogeny, progress in meiobenthos research defines a new and deeper scientific understanding.
Marine sediments dominate the global seabed, creating the largest ecosystem on earth. Seafloor biodiversity is a key mediator of ecosystem functioning, yet critical processes are often excluded from global biogeochemical budgets or simplified to black boxes in ecosystem models. This accessible textbook provides an ideal point of entry into the field, providing basic information on the nature of soft-sediment ecosystems, examples of how and why we research them, the new questions these studies inspire, and the applications that ultimately benefit society. While focussing on coastal habitats (<200m depth) to emphasize process-based experimental studies, it is relevant to the full range of marine sedimentary habitats. The authors describe the interactions between marine organisms and their physical and chemical environment, demonstrating the need for carefully designed research programs and providing the basic steps required to formulate sound ecological questions before applying them to empirical studies of real-world ecosystems. The book reveals the connections between different system components and drivers of change, examining how we can develop knowledge on the biodiversity and functioning of soft sediments and apply it to a better understanding of ecosystem change, human impacts, and effective restoration. Ecology of Coastal Marine Sediments is intended for advanced undergraduate and graduate students who have completed a general ecology course but received no further training in marine science. It will also be useful to both professional researchers and resource managers in marine ecology and environmental science who seek a compact and authoritative introduction to sediment ecology.
Ecological Methods by the late T.R. E. Southwood and revised over the years by P. A. Henderson has developed into a classic reference work for the field biologist. It provides a handbook of ecological methods and analytical techniques pertinent to the study of animals, with an emphasis on non-microscopic animals in both terrestrial and aquatic environments. It remains unique in the breadth of the methods presented and in the depth of the literature cited, stretching right back to the earliest days of ecological research. The universal availability of R as an open source package has radically changed the way ecologists analyse their data. In response, Southwood's classic text has been thoroughly revised to be more relevant and useful to a new generation of ecologists, making the vast resource of R packages more readily available to the wider ecological community. By focusing on the use of R for data analysis, supported by worked examples, the book is now more accessible than previous editions to students requiring support and ideas for their projects. Southwood's Ecological Methods provides a crucial resource for both graduate students and research scientists in applied ecology, wildlife ecology, fisheries, agriculture, conservation biology, and habitat ecology. It will also be useful to the many professional ecologists, wildlife biologists, conservation biologists and practitioners requiring an authoritative overview of ecological methodology.
Since the first edition of this book published in 2005, there has been an immense amount of new and fascinating work on the history, ecology, and evolution of the Mediterranean flora. During this time, human impacts have continued to increase dramatically, significantly influencing both the ecology and evolution of the region's biota. This timely and comprehensive update of the original text integrates a diverse and scattered literature to produce a synthetic account of Mediterranean plant evolutionary ecology. It maintains the accessible style of its previous version whilst incorporating recent work in a new structural framework. This is not a traditional "plant science" book per se, but a novel integration of history, ecology, biogeography, and evolution, all set in the context of a dramatically increasing human footprint. There is a particular emphasis on the role of human activities as an ecological factor and their subsequent impact on plant evolution. Conversely, it demonstrates how an understanding of the evolutionary ecology of the region's flora can be used to provide insights into its future conservation and management. Plant Evolution in the Mediterranean is aimed at all those who are interested in the biology of the Mediterranean region, whether it is taxonomy, ecology, evolution, conservation policy and management, or the regional history of its biodiversity in general. It will be of relevance and use to all graduate students and researchers of Mediterranean-type ecosystem ecology and geography, as well as professional ecologists, evolutionary biologists, conservation biologists, and environmental practitioners requiring a concise, authoritative overview of the topic.
The musteloids are the most diverse super-family among carnivores, ranging from little known, exotic, and highly-endangered species to the popular and familiar, and include a large number of introduced invasives. They feature terrestrial, fossorial, arboreal, and aquatic members, ranging from tenacious predators to frugivorous omnivores, span weights from a 100g weasel to 30kg giant otters, and express a range of social behaviours from the highly gregarious to the fiercely solitary. Musteloids are the subjects of extensive cutting-edge research from phylogenetics to the evolution of sociality and through to the practical implications of disease epidemiology, introduced species management, and climate change. Their diversity and extensive biogeography inform a wide spectrum of ecological theory and conservation practice. The editors of this book have used their combined 90 years of experience working on the behaviour and ecology of wild musteloids to draw together a unique network of the world's most successful and knowledgeable experts. The book begins with nine review chapters covering hot topics in musteloid biology including evolution, disease, social communication, and management. These are followed by twenty extensive case studies providing a range of comprehensive geographic and taxonomic coverage. The final chapter synthesises what has been discussed in the book, and reflects on the different and diverse conservation needs of musteloids and the wealth of conservation lessons they offer. Biology and Conservation of Musteloids provides a conceptual framework for future research and applied conservation management that is suitable for graduate level students as well as professional researchers in musteloid and carnivore ecology and conservation biology. It will also be of relevance and use to conservationists and wildlife managers.
The capacity of mixed forests to mitigate climate change effects by increasing resilience and lowering risks is pinpointed as an opportunity to highlight the role of tree species rich forests as part of complex socio-ecological systems. This book updates and presents the state-of-the-art of mixed forest performance in terms of regeneration, growth, yield and delivery of ecosystem services. Examples from more than 20 countries in Europe, North Africa and South America provide insights on the interplay between structure and functionining, stability, silviculture and optimization of management of this type of forests. The book also analyses the role of natural mixed forests and mixed plantations in the delivery of ecosystem services and the best modelling strategy to study mixed forest dynamics. The book is intended to serve as a reference tool for students, researchers and professionals concerned about the management of mixed forests in a context of social and environmental change. |
