TAILIEUCHUNG - Primary Succession and Ecosystem Rehabilitation

This book is for anyone interested in the consequences of disturbance. What happens after the lava cools, or when the muddy floodwaters recede or an old road is abandoned? Primary succession is the process of ecosystem development on barren surfaces where severe disturbances have removed most vestiges of biological activity. It includes the development of complex systems from simple biotic and abiotic (non-biological) components. Primary succession starts when plants, animals and microbes colonize new surfaces. The process is influenced by local conditions, context and site history. All newsurfaces are initially devoid of life, so primary succession has been crucial throughout Earth’s history. Today, all communities of plants, animals and soils. | Primary Succession and Ecosystem Rehabilitation Lawrence R. walker and Roger del Moral Cambridge Cambridge more information - 9780521800761 This page intentionally left blank Primary Succession and Ecosystem Rehabilitation Natural disturbances such as lava flows landslides and glacial moraines and human-damaged sites such as pavements road edges and mine wastes often leave little or no soil or biological legacy. This book provides the first comprehensive summary of how plant animal and microbial communities develop under the harsh conditions following such dramatic disturbances. The authors examine the basic principles that determine ecosystem development and apply the general rules to the urgent practical need for promoting the reclamation of damaged lands. Written for those concerned with disturbance landscape dynamics restoration life histories invasions modeling soil formation and community or population dynamics this book will also serve as an authoritative text for graduate students and a valuable reference for professionals involved in land management. Lawrence R. Walker is Professor of Biological Sciences at the University of Nevada Las Vegas. His research focuses on the mechanisms that drive primary succession and the applications of succession to restoration. Roger del Moral is Professor of Botany at the University of Washington. His research relates observed patterns of vegetation recovery to ecological .
