The earth's landscapes are being increasingly impacted by the activities of man. Unfortunately, we do not have a full understanding of the consequences of these disturbances on the earth's productive capacity. This problem was addressed by a group of French and U.S. ecologists who are specialists at levels of integration extending from genetics to the biosphere at a meeting at Stanford, California, sponsored by the National Science Foundation and the Centre National de la Recherche Scientifique. With a few important exceptions it was found at this meeting that most man-induced disturbances of ecosystems can be viewed as large scale patterns of disturbances that have occurred, generally on a small scale, in ecosystems through evolutionary time. Man has induced dramatic large-scale changes in the environment which must be viewed at the biosphere level. Acid deposition and CO increase are two 2 examples of the consequences of man's increased utilization of fossil fuels. It is a matter of considerable concern that we cannot yet fully predict the ecological consequences of these environmental changes. Such problems must be addressed at the international level, yet substantive mechanisms to do this are not available.

Ecological and environmental research has increased in scope and complexity in the last few decades, from simple systems with a few managed variables to complex ecosystems with many uncontrolled variables. These issues encompass problems that are inadequately addressed using the types of carefully controlled experiments that dominate past ecological research. Contemporary challenges facing ecologists include whole ecosystem responses to planned restoration activities and ecosystem modifications, as well as unplanned catastrophic events such as biological invasions, natural disasters, and global climate changes. Major perturbations implicated in large-scale ecological alterations share important characteristics that challenge traditional experimental design and statistical analyses. These include: * Lack of randomization, replication and independence * Multiple scales of spatial and temporal variability * Complex interactions and system feedbacks. In real world ecology, standard replicated designs are often neither practical nor feasible for large-scale experiments, yet ecologists continue to cling to these same standard designs and related statistical analyses. Case studies that fully elucidate the currently available techniques for conducting large-scale unreplicated analyses are lacking. Real World Ecology: Large-Scale and Long-Term Case Studies and Methods is the first to focus on case studies to demonstrate how ecologists can investigate complex contemporary problems using new and powerful experimental approaches. This collection of case studies showcases innovative experimental designs, analytical options, and interpretation possibilities currently available to theoretical and applied ecologists, practitioners, and biostatisticians. By illustrating how scientists have answered pressing questions about ecosystem restoration, impact and recovery, global warming, conservation, modeling, and biological invasions, this book will broaden the acceptance and application of modern approaches by scientists and encourage further methodological development.

This book focuses on the ecological impacts of the Great East Japan Earthquake and resulting tsunamis, a rare and extremely large disturbance event, on various coastal ecosystems in Japan’s Tohoku area, including sub-tidal and tidal animal communities, sand dune plant communities and coastal forests. The studies presented here describe not only how species and populations in these ecosystems were disturbed by the earthquake and tsunamis, but also how the communities have responded to the event and what types of anthropogenic activities will hamper their recovery processes. In the ecological sciences, it is often argued that large disturbances are critical to shaping community structures and biodiversity in local and regional habitats. However, our understanding of these roles remains limited, simply because there have been few opportunities to examine and address the ecological impacts of large disturbance events. The scale of the 2011 Great East Japan Earthquake makes it one of the largest hazards in the past 1000 years. Thus, this book provides a unique opportunity to advance our understanding of the ecological impacts of large and rare disturbances and the implications of these events in the conservation and management of coastal ecosystems. Following an outline of the Great East Japan Earthquake, the book’s content is divided into two major parts. Part I reports on studies examining the ecological impacts of the tsunamis on sub-tidal and tidal animal communities, while Part II focuses on terrestrial plant communities in Japan’s coastal Tohoku area. This book will benefit all scientists interested in the ecological impacts of large disturbances on aquatic and terrestrial ecosystems in general, and especially those who are interested in the ecological management of coastal ecosystems and Ecosystem based Disaster Risk Reduction (EcoDRR).

This edited work presents a multi-faceted view on the causes and consequences of disturbance in ecosystems. Vegetation can be affected by a variety of different disturbances such as wind, floods, fire, and insect attack, leading to an abrupt change in live biomass. Disturbance is a motor of vegetation dynamics, but also sensitive to climate change and poses a challenge for ecosystem management. Readers will discover the global distribution of disturbance regimes and learn about the importance of disturbances for biodiversity and the evolution of plant and animal life. The book provides a Central European perspective on disturbance ecology, and addresses important disturbance agents such as fire, wind, avalanches, tree diseases, insect defoliators, bark beetles and large herbivores in dedicated chapters. It furthermore includes chapters on anthropogenic disturbances in forests and grasslands. The impact of climate change on disturbance regimes and approaches to address disturbance risks in ecosystem management are discussed in concluding chapters. Within the 18 chapters 14 textboxes highlight current topics of disturbance ecology and provide deeper methodological insights into the field. Disturbances strongly shape our landscapes and maintain our biodiversity. A better understanding of their ecology is thus fundamental for contextualizing the dynamic changes in our environment. This book is a valuable resource for students and practitioners interested in disturbances and their management.

Scientists and researchers concerned with the behavior of large ecosystems have focused in recent years on the concept of "resilience." Traditional perspectives held that ecological systems exist close to a steady state and resilience is the ability of the system to return rapidly to that state following perturbation. However beginning with the work of C. S. Holling in the early 1970s, researchers began to look at conditions far from the steady state where instabilities can cause a system to shift into an entirely different regime of behavior, and where resilience is measured by the magnitude of disturbance that can be absorbed before the system is restructured. Resilience and the Behavior of Large-Scale Systems examines theories of resilience and change, offering readers a thorough understanding of how the properties of ecological resilience and human adaptability interact in complex, regional-scale systems. The book addresses the theoretical concepts of resilience and stability in large-scale ecosystems as well as the empirical application of those concepts in a diverse set of cases. In addition, it discusses the practical implications of the new theoretical approaches and their role in the sustainability of human-modified ecosystems. The book begins with a review of key properties of complex adaptive systems that contribute to overall resilience, including multiple equlibria, complexity, self-organization at multiple scales, and order; it also presents a set of mathematical metaphors to describe and deepen the reader's understanding of the ideas being discussed. Following the introduction are case studies that explore the biophysical dimensions of resilience in both terrestrial and aquatic systems and evaluate the propositions presented in the introductory chapters. The book concludes with a synthesis section that revisits propositions in light of the case studies, while an appendix presents a detailed account of the relationship between return times for a disturbed system and its resilienc. In addition to the editors, contributors include Stephen R. Carpenter, Carl Folke, C. S. Holling, Bengt-Owe Jansson, Donald Ludwig, Ariel Lugo, Tim R. McClanahan, Garry D. Peterson, and Brian H. Walker.
