Natural disturbances such as lava flows, landslides and glacial moraines, and human-damaged sites such as pavement, road edges and mine wastes often leave little or no soil or biological legacy. This 2003 book provided 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 ecologists 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.

Much effort has been devoted to developing theories to explain the wide variation we observe in reproductive allocation among environments. Reproductive Allocation in Plants describes why plants differ in the proportion of their resources that they allocate to reproduction and looks into the various theories. This book examines the ecological and evolutionary explanations for variation in plant reproductive allocation from the perspective of the underlying physiological mechanisms controlling reproduction and growth. An international team of leading experts have prepared chapters summar

The eruption of Mount St. Helens on May 18, 1980, had a momentous impact on the fungal, plant, animal, and human life from the mountain to the far reaches of the explosion's ash cloud and mudflows. Although this intense natural event caused loss of substantial life and property, it also created a unique opportunity to examine a huge disturbance of natural systems and their subsequent responses. Based on one of the most studied areas of volcanic activity, this book synthesizes the ecological research that has been conducted for twenty-five years since the eruption. Research from geology as well as plant and animal ecology has been integrated in this unprecedented look at the complex interactions of biological and physical systems in the response of the volcanic landscape. Lessons from the volcano inform our larger understanding of ecosystem disturbances, natural processes, and the impact of land-use practices. Included are results of significant and long-term research on vegetation, mycorrhizae, plant and animal interactions, arthropods, amphibians, mammals, fish, lakes, nutrient cycling, geomorphology, and environmental management. This comprehensive account will be of value to those interested in natural history, ecology, disturbance, conservation biology, limnology, geoscience, and land management. Questions about what actually happens when a volcano erupts, what the immediate and long-term dangers are, and how life reasserts itself in the environment are discussed in full detail.

The study of ecosystems, fundamental to ecology, has been complemented by the growing field of landscape ecology. Ecosystem Function in Heterogeneous Landscapes addresses how interactions among ecosystems affect the functioning of individual ecosystems and the larger landscape. This groundbreaking synthesis unites ecosystem ecology's knowledge of system function with landscape ecology's knowledge of spatial structure. Practical concerns about scaling up from individual ecosystems to larger landscapes require an understanding of how networks of interacting ecosystems function together. The book elucidates the challenges faced by ecosystem scientists working in spatially heterogeneous systems, relevant conceptual approaches used in other disciplines and in different ecosystem types, and the importance of spatial heterogeneity in conservation resource management. The distinguished authors discuss how how much heterogeneity needs to be taken into account for specific types of scientific and management issues. Their chapters cover the spectrum from proposing novel conceptual approaches to detailing the practical implications of heterogeneous landscapes for fire management, water management and conservation planning.

While studies of restoration and ecological succession have been published independently, there is much overlap between these approaches that has not been adequately explored. Linking Restoration and Ecological Succession integrates practical information from restoration projects around the world with the latest developments in successional theory. This innovative book recognizes the critical roles of disturbance ecology, landscape ecology, ecological assembly, invasion biology, ecosystem health, and historical ecology in habitat restoration and argues that restoration within a successional context will best utilize the lessons from each of these disciplines. To successfully restore an ecosystem that needs minimal care, the temporal dynamics of successional processes must be considered. By re-examining restoration in the light of succession, the authors hope to encourage the development of new approaches to the practice of restoration supported by solid ecological principles.
