The Long-Term Ecological Research Network Series – serie

The Coastal Everglades presents a broad overview and synthesis of research on the coastal Everglades, a region that includes Everglades National Park, adjacent managed wetlands, and agricultural and urbanizing communities. Contributors for this volume are all collaborators on the Florida Coastal Everglades Long-Term Ecological Research Program (FCE LTER). The FCE LTER began in 2000 with a focus on understanding key ecosystem processes in the coastal Everglades, while also developing a platform for and linkages to related work conducted by an active and diverse Everglades research community. The program is based at Florida International University in Miami, but includes scientists and students from numerous other universities as well as staff scientists at key resource management agencies, including Everglades National Park and the South Florida Water Management District.Though the Everglades landscape spans nearly a third of the State of Florida, the focus on the coastal Everglades has allowed the contributors to examine key questions in social-ecological science in the context of ongoing restoration initiatives. As this book demonstrates, the long-term research of the FCE LTER has facilitated a better understanding of the roles of sea level rise, water management practices, urban and agricultural development, and other disturbances, such as fires and storms, on the past and future dynamics of this unique coastal environment. By comparing properties of the Everglades with other subtropical and tropical wetlands, the book challenges ideas of novelty while revealing properties of ecosystems at the ends of gradients that are often ignored. It also provides insights from, and encouragement for, long-term collaborative studies that inform resource management in similarly threatened coastal wetland landscapes.

This book is the first in a series of planned synthesis volumes from sites funded by the National Science Foundation's Long-term Ecological Research Program. This volume focuses on over 15 years of research at the Konza Prairie in NE Kansas and provides a unique perspective on the structural and functional ecology of a grassland ecosystem that once covered most of central North America.

This book provides a complete overview of an alpine ecosystem, based on the long-term research conducted at the Niwot Ridge LTER. There is, at present, no general book on alpine ecology. The alpine ecosystem features conditions near the limits of biological existence, and is a useful laboratory for asking more general ecological questions, because it offers large environmental change over relatively short distances. Factors such as macroclimate, microclimate, soil conditions, biota, and various biological factors change on differing scales, allowing insight into the relative contributions of the different factors on ecological outcomes.

Standardized methods and measurements are crucial for ecological research, particularly in long-term ecological studies where the projects are by nature collaborative and where it can be difficult to distinguish signs of environmental change from the effects of differing methodologies. This second volume in the Long-Term Ecological Research Network Series addresses these issues directly by providing a comprehensive standardized set of protocols for measuring soil properties. The goal of the volume is to facilitate cross-site synthesis and evaluation of ecosystem processes. Chapters cover methods for studying physical and chemical properties of soils, soil biological properties, and soil organisms, and they include work from many leaders in the field. The book is the first broadly based compendium of standardized soil measurement methods and will be an invaluable resource for ecologists, agronomists, and soil scientists.

Global change threatens ecosystems worldwide, and tropical systems with their high diversity and rapid development are of special concern. We can mitigate the impacts of change if we understand how tropical ecosystems respond to disturbance. For tropical forests and streams in Puerto Rico this book describes the impacts of, and recovery from, hurricanes, landslides, floods, droughts, and human disturbances in the Luquillo Mountains of Puerto Rico. These ecosystems recover quickly after natural disturbances, having been shaped over thousands of years by such events. Human disturbance, however, has longer-lasting impacts. Chapters are by authors with many years of experience in Puerto Rico and other tropical areas and cover the history of research in these mountains, a framework for understanding disturbance and response, the environmental setting, the disturbance regime, response to disturbance, biotic mechanisms of response, management implications, and future directions. The text provides a strong perspective on tropical ecosystem dynamics over multiple scales of time and space.

This latest addition to the Long-Term Ecological Research Network series gives an overarching account of the recovery and management of a forest watershed ecosystem. It synthesizes and cross-references important and rare-to find, long-term data in 14 chapters that deal with the hydrologic, biogeochemical, and ecological processes of mixed deciduous forests. The data is representative of the entire U.S., and shows the effects of commercial clearcutting using examples from the Southeastern U.S. and a range of East coast forests. It includes responses of both forest and stream components of the watershed and provides unique insights into the interrelationships between the effects of natural disturbances (floods, droughts, insects, and disease, etc.) versus management disturbances.Clearly illustrating the importance and need for long-term research to evaluate recovery processes of long-lived ecosystems, the work will serve academics, professionals, and students seeking to understand more fully the effects of forest-cutting on forest and stream ecosystems.

Evidence has been mounting for some time that intensive row-crop agriculture as practiced in developed countries may not be environmentally sustainable, with concerns increasingly being raised about climate change, implications for water quantity and quality, and soil degradation. This volume synthesizes two decades of research on the sustainability of temperate, row-crop ecosystems of the Midwestern United States. The overarching hypothesis guiding this work has been that more biologically based management practices could greatly reduce negative impacts while maintaining sufficient productivity to meet demands for food, fiber and fuel, but that roadblocks to their adoption persist because we lack a comprehensive understanding of their benefits and drawbacks. The research behind this book, based at the Kellogg Biological Station (Michigan State University) and conducted under the aegis of the Long-term Ecological Research network, is structured on a foundation of large-scale field experiments that explore alternatives to conventional, chemical-intensive agriculture. Studies have explored the biophysical underpinnings of crop productivity, the interactions of crop ecosystems with the hydrology and biodiversity of the broader landscapes in which they lie, farmers' views about alternative practices, economic valuation of ecosystem services, and global impacts such as greenhouse gas exchanges with the atmosphere. In contrast to most research projects, the long-term design of this research enables identification of slow or delayed processes of change in response to management regimes, and allows examination of responses across a broader range of climatic variability. This volume synthesizes this comprehensive inquiry into the ecology of alternative cropping systems, identifying future steps needed on the path to sustainability.
