I was asked to introduce this volume by examining "why a knowledge of ecosys tem functioning can contribute to understanding species activities, dynamics, and assemblages." I have found it surprisingly difficult to address this topic. On the one hand, the answer is very simple and general: because all species live in ecosystems, they are part of and dependent on ecosystem processes. It is impossible to understand the abundance and distribution of populations and the species diversity and composition of communities without a knowledge of their abiotic and biotic environments and of the fluxes of energy and mat ter through the ecosystems of which they are a part. But everyone knows this. It is what ecology is all about (e.g., Likens, 1992). It is why the discipline has retained its integrity and thrived, despite a sometimes distressing degree of bickering and chauvinism among its various subdisciplines: physiological, be havioral, population, community, and ecosystem ecology.

This is the first volume devoted to the integration of population and ecosystem ecology--an approach that offers vast potential for improving our understanding of the complexities of nature and the management of environmental problems. The editors, Clive Jones and John Lawton, work at the Institute of Ecosystem Studies in New York and the Natural Environment Research Council Centre for Population Biology in England, respectively. They have brought together a distinguished group of experts to explore diverse aspects of linking species and ecosystem perspectives: theoretical, empirical and pragmatic including: *processes that range from a local to a planetary scale *the role of organisms as ecosystem engineers *the use of ecological flow chains to link population and ecosystem processes *numerous examples of the influence of species on ecosystem processes and vice versa *a unique blend of problems and processes drawn from marine, freshwater and terrestrial ecosystems *problems of species redundancy in ecosystem processes *stoichiometric constraints on species interactions; *scaling and aggregation problems. The book establishes conceptual frameworks for the rigorous study of interactions between species and ecosystems, it points to still-unanswered questions, and it identifies future research directions. Integration of ecology with its implications for teaching, research and society are central to the book. This pioneering volume will be an indispensable resource for ecology researchers, students, and environmental managers and will stimulate debate on the future integration of the field.

The term biodiversity has become a mainstream concept that can be found in any newspaper at any given time. Concerns on biodiversity protection are usually linked to species protection and extinction risks for iconic species, such as whales, pandas and so on. However, conserving biodiversity has much deeper implications than preserving a few (although important) species. Biodiversity in ecosystems is tightly linked to ecosystem functions such as biomass production, organic matter decomposition, ecosystem resilience, and others. Many of these ecological processes are also directly implied in services that the humankind obtains from ecosystems. The first part of this book will introduce different concepts and theories important to understand the links between ecosystem function and ecosystem biodiversity. The second part of the book provides a wide range of different studies showcasing the evidence and practical implications of such relationships.

Why do species live where they live? What determines the abundance and diversity of species in a given area? What role do species play in the functioning of entire ecosystems? All of these questions share a single core concept—the ecological niche. Although the niche concept has fallen into disfavor among ecologists in recent years, Jonathan M. Chase and Mathew A. Leibold argue that the niche is an ideal tool with which to unify disparate research and theoretical approaches in contemporary ecology. Chase and Leibold define the niche as including both what an organism needs from its environment and how that organism's activities shape its environment. Drawing on the theory of consumer-resource interactions, as well as its graphical analysis, they develop a framework for understanding niches that is flexible enough to include a variety of small- and large-scale processes, from resource competition, predation, and stress to community structure, biodiversity, and ecosystem function. Chase and Leibold's synthetic approach will interest ecologists from a wide range of subdisciplines.

Migrating wildlife species across the globe face a dire predicament as their traditional migratory routes are cut off by human encroachment. Forced into smaller and smaller patches of habitat, they must compete more aggressively for dwindling food resources and territory. This is more than just an unfortunate side effect of human progress. As key species populations dwindle, ecosystems are losing resilience and face collapse, and along with them, the ecosystem services we depend on. Healthy ecosystems need healthy wildlife populations. One possible answer? Wildlife corridors that connect fragmented landscapes. This new and expanded second edition of Corridor Ecology: Linking Landscapes for Biodiversity Conservation and Climate Adaptation captures the many advances in the field over the past ten years. It builds on concepts presented in the first edition on the importance and practical details of maintaining and restoring land connectivity. New to this edition is a guest-edited chapter on ecological connectivity in oceans, including a detailed discussion on pelagic marine corridors and how coastal corridors can provide critical connectivity between marine protected areas. Another new chapter considers the effects of climate change on habitat and offers recommendations on designing effective corridors as landscapes change with shifting climate conditions. The book also includes a discussion of corridors in the air for migrating flying species, from birds to bats, butterflies, and even plant propagules—a concept so new that a term to describe it has yet to be coined. All chapters are thoroughly revised and updated. Practitioners as well as serious scholars of landscape ecology and the science of protecting biodiversity will find this new edition of corridor ecology science an indispensable resource.

There is a gap between the ecology of health and the concepts supported by international initiatives such as EcoHealth, One Health or Planetary Health; a gap which this book aims to fill. Global change is accelerated by problems of growing population, industrialization and geopolitics, and the world's biodiversity is suffering as a result, which impacts both humans and animals. However, Biodiversity and Health offers the unique opportunity to demonstrate how ecological, environmental, medical and social sciences can contribute to the improvement of human health and wellbeing through the conservation of biodiversity and the services it brings to societies. This book gives an expansive and integrated overview of the scientific disciplines that contribute to the connection between health and biodiversity, from the evolutionary ecology of infectious and non-infectious diseases to ethics, law and politics. - Presents the first book to give a broad and integrated overview of the scientific disciplines that contribute to health - From evolutionary ecology, to laws and policies, this book explores the links between health and biodiversity - Demonstrates how ecological sciences, environmental sciences, medical sciences, and social sciences may contribute to improve human health

The major subdisciplines of ecology--population ecology, community ecology, ecosystem ecology, and evolutionary ecology--have diverged increasingly in recent decades. What is critically needed today is an integrated, real-world approach to ecology that reflects the interdependency of biodiversity and ecosystem functioning. From Populations to Ecosystems proposes an innovative theoretical synthesis that will enable us to advance our fundamental understanding of ecological systems and help us to respond to today's emerging global ecological crisis. Michel Loreau begins by explaining how the principles of population dynamics and ecosystem functioning can be merged. He then addresses key issues in the study of biodiversity and ecosystems, such as functional complementarity, food webs, stability and complexity, material cycling, and metacommunities. Loreau describes the most recent theoretical advances that link the properties of individual populations to the aggregate properties of communities, and the properties of functional groups or trophic levels to the functioning of whole ecosystems, placing special emphasis on the relationship between biodiversity and ecosystem functioning. Finally, he turns his attention to the controversial issue of the evolution of entire ecosystems and their properties, laying the theoretical foundations for a genuine evolutionary ecosystem ecology. From Populations to Ecosystems points the way to a much-needed synthesis in ecology, one that offers a fuller understanding of ecosystem processes in the natural world.

What can ecological science contribute to the sustainable management and conservation of the natural systems that underpin human well-being? Bridging the natural, physical and social sciences, this book shows how ecosystem ecology can inform the ecosystem services approach to environmental management. The authors recognise that ecosystems are rich in linkages between biophysical and social elements that generate powerful intrinsic dynamics. Unlike traditional reductionist approaches, the holistic perspective adopted here is able to explain the increasing range of scientific studies that have highlighted unexpected consequences of human activity, such as the lack of recovery of cod populations on the Grand Banks despite nearly two decades of fishery closures, or the degradation of Australia's fertile land through salt intrusion. Written primarily for researchers and graduate students in ecology and environmental management, it provides an accessible discussion of some of the most important aspects of ecosystem ecology and the potential relationships between them.
