Linking Species Ecosystems

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.

One major consequence of climate change is abrupt, dramatic changes in regional biodiversity. Even if the most optimistic scenarios for mitigating climate change transpire, the fate of many wild species rests on the shoulders of people engaged in conservation planning, management, and policy. Providing managers with the latest and most useful climate change research is critical and requires challenging the conventional divide between scientists and managers. Biodiversity in a Changing Climate promotes dialogue among scientists, decision makers, and managers who are grappling with climate-related threats to species and ecosystems in diverse forms. The book includes case studies and best practices used to address impacts related to climate change across a broad spectrum of species and habitats—from coastal krill and sea urchins to prairie grass and mountain bumblebees. Focused on California, the issues and strategies presented in this book will prove relevant to regions across the West, as well as other regions, and provide a framework for how scientists and managers in any region can bridge the communication divide to manage biodiversity in a rapidly changing world. Biodiversity and a Changing Climate will prove an indispensable guide to students, scientists, and professionals engaged in conservation and resource management.

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.

Advances in Ecological Research, Volume 61, the latest release in this ongoing series includes specific chapters on the Mechanistic links between biodiversity and ecosystem function, A multitrophic, eco-evolutionary perspective on biodiversity–ecosystem functioning research, Linking species coexistence to ecosystem functioning - a conceptual framework from ecological first principles, Species contributions to above and below ground biodiversity effects in the Trait-Based Experiment, Plant diversity effects on element cycling, Plant diversity effects on consumer community structure, stability, and ecosystem function, Plant community assembly and the consequences for ecosystem function, and more. Provides information that relates to a thorough understanding of the field of ecology Deals with topical and important reviews on the physiologies, populations and communities of plants and animals

Corridor Ecology presents guidelines that combine conservation science and practical experience for maintaining, enhancing, and creating connectivity between natural areas with an overarching goal of conserving biodiversity. It offers an objective, carefully interpreted review of the issues and is a one-of-a-kind resource for scientists, landscape architects, planners, land managers, decision-makers, and all those working to protect and restore landscapes and species diversity.

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.
