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.

Disturbance ecology continues to be an active area of research, having undergone advances in many areas in recent years. One emerging direction is the increased coupling of physical and ecological processes, in which disturbances are increasingly traced back to mechanisms that cause the disturbances themselves, such as earth surface processes, mesoscale, and larger meteorological processes, and the ecological effects of interest are increasingly physiological. Plant Disturbance Ecology, 2nd Edition encourages movement away from the informal, conceptual approach traditionally used in defining natural disturbances and clearly presents how scientists can use a multitude of approaches in plant disturbance ecology. This edition includes nine revised chapters from the first edition, as well new, more comprehensive chapters on fire disturbance and beaver disturbance. Edited by leading experts in the field, Plant Disturbance Ecology, 2nd Edition is an essential resource for scientists interested in understanding plant disturbance and ecological processes. - Advances understanding of natural disturbances by combining geophysical and ecological processes - Provides a framework for collaboration between geophysical scientists and ecologists studying natural disturbances - Includes fully updated research with 5 new chapters and revision of 11 chapters from the first edition

Most large herbivores require some type of management within their habitats. Some populations of large herbivores are at the brink of extinction, some are under discussion for reintroduction, whilst others already occur in dense populations causing conflicts with other land use. Large herbivores are the major drivers for forming the shape and function of terrestrial ecosystems. This 2006 book addresses the scientifically based action plans to manage both the large herbivore populations and their habitats worldwide. It covers the processes by which large herbivores not only affect their environment (e.g. grazing) but are affected by it (e.g. nutrient cycling) and the management strategies required. Also discussed are new modeling techniques, which help assess integration processes in a landscape context, as well as assessing the consequences of new developments in the processes of conservation. This book will be essential reading for all involved in the management of both large herbivores and natural resources.

Ecologists are aware of the importance of natural dynamics in ecosystems. Historically, the focus has been on the development in succession of equilibrium communities, which has generated an understanding of the composition and functioning of ecosystems. Recently, many have focused on the processes of disturbances and the evolutionary significance of such events. This shifted emphasis has inspired studies in diverse systems. The phrase "patch dynamics" (Thompson, 1978) describes their common focus. The Ecology of Natural Disturbance and Patch Dynamics brings together the findings and ideas of those studying varied systems, presenting a synthesis of diverse individual contributions.

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.

This book presents cascading effects of ecological disturbances on a multitude of ecosystem components. It includes agricultural development, large infrequent disturbances, forest harvesting, non-native grazing in deserts, ground transportation, powerline corridors, fires, urban ecology, disturbance in aquatic ecosystems, land-use dynamics on diversity, habitat fragmentation, sedimentation of wetlands, and contemporary climate change. The book facilitates users in understanding why disturbances are occurring while recommending mitigation and remediation strategies.
