Book Description
Ecology has long been shaped by ideas that stress the sharing of resources and the competition for those resources, and by the assumption that populations and communities typically exist under equilibrium conditions in habitats saturated with both individuals and species. However, much evidence contradicts these assumptions and it is likely that nonequilibrium is much more widespread than might be expected. This book is unique in focusing on nonequilibrium aspects of ecology, providing evidence for nonequilibrium and equilibrium in populations (and metapopulations), in extant communities and in ecological systems over evolutionary time, including nonequilibrium due to recent and present mass extinctions. The assumption that competition is of overriding importance is central to equilibrium ecology, and much space is devoted to its discussion. As communities of some taxa appear to be shaped more by competition than others, an attempt is made to find an explanation for these differences.

Book Description
This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.

Book Description
It is clear that nature is undergoing rapid changes as a result of human activities such as industry, agriculture, travel, fisheries and urbanisation. What effects do these activities have? Are they disturbing equilibria in ecological populations and communities, thus upsetting the balance of nature, or are they enhancing naturally occurring disequilibria, perhaps with even worse consequences? It is often argued that large-scale fluctuations in climate and sea-levels have occurred over and over again in the geological past, long before human activities could possibly have had any impact, and that human effects are very small compared to those that occur naturally. Should we conclude that human activity cannot significantly affect the environment, or are these naturally occurring fluctuations actually being dangerously enhanced by humans? This book examines these questions, first by providing evidence for equilibrium and non-equilibrium conditions in relatively undisturbed ecosystems, and second by examining human-induced effects.

Book Description
A philosophical and narrative memoir, Ecology and Experience is a thoughtful, engaging recounting of author Richard J. Borden’s life entwined in an overview of the intellectual and institutional history of human ecology—a story of life wrapped in a life story. Borden shows that attempts to bridge the mental and environmental arenas are uncertain, but that rigid conventions and narrow views have their dangers too. Human experience and the natural world exist on many levels and gathering from both realms gives rise to novel constellations. In a blend of themes and approaches based on a lifetime of interdisciplinary inquiry, the author wanders these intersections and invites us to exercise our capacities for ecological insight, to deepen the experience of being alive, and, most of all, to more fully enrich our lives.

Book Description
Wood ants play an ecologically dominant and conspicuous role in temperate boreal forests, making a keystone contribution to woodland ecosystem functions and processes. Wood ant taxonomy and global distributions set the scene for this text's exploration of wood ants as social insects, examining their flexible social structures, genetics, population ecology, and behaviour, from nest-mate recognition to task allocation. Wood ants' interactions with their environment and with other organisms are essential to their success: competition, predation and mutualism are described and analysed. Bringing together the expertise of ecological researchers and conservation practitioners, this book provides practical and theoretical advice about sampling and monitoring these insects, and outlines the requirements for effective conservation. This is an indispensable resource for wood ant researchers, entomologists, conservationists and ecological consultants, as well as anyone interested in social insects, keystone species and the management and conservation of forest ecosystems.

Book Description
Animal population ecology comprises the study of variations, regulation, and interactions of animal populations. This book discusses the fundamental notions and findings of animal populations on which most of the ecological studies are based. In particular, the author selects the logistic law of population growth, the nature of competition, sociality as an antithesis of competition, the mechanism underlying the regulation of populations, predator-prey interaction processes, and interactions among closely related species competing over essential resources. These are the notions that are considered to be well-established facts or principles and are regularly taught at ecology classes or introduced in standard textbooks. However, the author demonstrates that these notions are still inadequately understood, or even misunderstood, creating myths that would misguide ecologists in carrying out their studies. He delves deeply into those notions to reveal their real nature and draws a road map to the future development of ecology.

Book Description
Despite their often dangerous and unpredictable nature, landslides provide fascinating templates for studying how soil organisms, plants and animals respond to such destruction. The emerging field of landslide ecology helps us understand these responses, aiding slope stabilisation and restoration and contributing to the progress made in geological approaches to landslide prediction and mitigation. Summarising the growing body of literature on the ecological consequences of landslides, this book provides a framework for the promotion of ecological tools in predicting, stabilising, and restoring biodiversity to landslide scars at both local and landscape scales. It explores nutrient cycling; soil development; and how soil organisms disperse, colonise and interact in what is often an inhospitable environment. Recognising the role that these processes play in providing solutions to the problem of unstable slopes, the authors present ecological approaches as useful, economical and resilient supplements to landslide management.

Book Description
Environmental Regulation: Law, Science, and Policy demystifies the complexity of environmental law. It provides up-to-date, comprehensive and accessible coverage of this growing and rapidly changing field. After exploring the causes of environmental problems and the moral values they implicate, the casebook provides a structural overview of the regulatory system. It considers how environmental law seeks to protect public health and the environment from climate change, toxic chemicals, hazardous wastes, and air and water pollution. This casebook also covers land use regulation, protection of biodiversity, environmental impact assessment, environmental enforcement, and international environmental law. Written in a style accessible to the non-specialist, this casebook affords instructors flexibility in organizing courses. Effective teaching and study aids include outlines of the structure of each environmental statute, real-world-based problems and questions, “pathfinders” explaining where to find crucial source materials for every major topic, an extensive glossary, and a list of acronyms. The casebook is kept current with annual statutory and case supplements. New to the Tenth Edition: ● West Virginia v. EPA and the amorphous “major questions” doctrine ● Sackett v. EPA narrows the reach of the Clean Water Act’s protection of wetlands ● State climate and environmental rights litigation ● The Inflation Reduction Act of 2022 and the green energy transition ● 2023 amendments to the National Environmental Policy Act ● Papal climate encyclical Laudato Si updated by Pope Francis Professors and students will benefit from: ● comprehensive and up-to-date coverage in a style accessible to the non-specialist ● self-contained chapters for flexibility in organizing courses ● a detailed examination of policy focus on environmental statutes how statutes translate into regulations factors that affect real-world behavior ● effective teaching and study aids outlines of the structure of each environmental statute real-world-based problems and questions “pathfinders” explaining where to find crucial source materials for every major subject area extensive glossary list of acronyms
