Book Description
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 (LTER) 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.

Book Description
Our North American forests are no longer the wild areas of past centuries; they are an economic and ecological resource undergoing changes from both natural and management disturbances. A watershed-scale and long-term perspective of forest ecosystem responses is requisite to understanding and predicting cause and effect relationships. This book synthesizes interdisciplinary studies conducted over thirty years, to evaluate responses of a clear-cut, cable-logged watershed at the Coweeta Hydrologic Laboratory in the Nantahala Mountain Range of western North Carolina. This research was the result of collaboration among Forest Service and university researchers on the most studied watershed in the Lab's 78-year history. During the experiment, a variety of natural disturbances occurred: two record floods, two record droughts, a major hurricane, a blizzard of the century, major forest diseases, and insect infestations. These disturbances provided a unique opportunity to study how they altered the recovery of the forest ecosystem. This book also shows that some long-term forest trends cannot be forecast from short-term findings, which could lead to incorrect conclusions of cause and effect relationships and natural resource management decisions.

Book Description
This handbook provides an overview of physical, chemical and biological methods used to analyze soils and plant tissue using an ecosystem perspective. The current emphasis on climate change has recognized the importance of including soil carbon as part of our carbon budgets. Methods to assess soils must be ecosystem based if they are to have utility for policy makers and managers wanting to change soil carbon and nutrient pools. Most of the texts on soil analyis treat agriculture and not forest soils and these methods do not transfer readily to forests because of their different chemistry and physical properties. This manual presents methods for soil and plant analysis with the ecosystem level approach that will reduce the risk that poor management decisions will be made in forests. This manual was intended for the instructors that teach students soil and plant analyses; however it can also be used by the research laboratories and by environmental scientists. The laboratory procedures in this manual are outlined in easy-to-follow steps and frequently accompanied with examples of calculations, questions to answer, and also a blank data sheet to use. These methods used in this manual can be used on soil and plant tissues found in agricultural, horticulture, forestry, urban, and natural lands.

Book Description
Creating and Restoring Wetlands: From Theory to Practice, Second Edition describes the challenges and opportunities relating to the restoration of freshwater and estuarine wetlands in natural, agricultural, and urban environments in the coming century. This second edition is structured by clearly defined chapters based on specific wetland types (e.g. Peatlands, Mangroves) and with a consistent and coherent organization for ease of discoverability. The table of contents is divided into four main subjects: Foundations, Restoration of Freshwater Wetlands, Restoration of Estuarine Wetlands, and From Theory to Practice, each with multiple chapters. Part 1, Foundations, contains chapters describing definitions of wetlands, ecological theory used to guide restoration, and considerations on where to implement restoration on the landscape. In Parts 2 and 3, restoration of specific freshwater (marshes, forests, peatlands) and estuarine (tidal marshes, mangroves) wetlands are described. Part 4, From Theory to Practice, contains chapters describing performance standards to gauge success of projects and case studies describing small-scale and large-scale restoration projects of various freshwater and estuarine wetlands. Each chapter contains clearly labeled sections which assist the reader to quickly and easily key in on the subject matter that they are seeking. The approach of Creating and Restoring Wetlands is unique in that, in each chapter, it links ecological theory important to ecosystem restoration with practical techniques to undertake and implement successful wetland restoration projects, including recommendations for performance standards to gauge success as well as realistic expectations and timescales for achieving success. Each chapter ends with a summary table describing keys to ensure success for a given wetland ecosystem. - Each chapter ends with a summary table describing keys to ensure success for a given wetland ecosystem - Written by a single author, providing a consistent structure that is coherent, cohesive and well referenced - Contains case studies of small- and large-scale restoration activities ensuring relevance to individuals and organizations

Book Description
Much attention has been given to above ground biomass and its potential as a carbon sink, but in a mature forest ecosystem 40 to 60 percent of the stored carbon is below ground. As increasing numbers of forests are managed in a wide diversity of climates and soils, the importance of forest soils as a potential carbon sink grows. The Potenti

Book Description
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.

Book Description
Ecology of the Shortgrass Steppe: A Long-Term Perspective summarizes and synthesizes more than sixty years of research that has been conducted throughout the shortgrass region in North America. The shortgrass steppe was an important focus of the International Biological Program's Grassland Biome project, which ran from the late 1960s until the mid-1970s. The work conducted by the Grassland Biome project was preceded by almost forty years of research by U.S. Department of Agriculture researchers-primarily from the Agricultural Research Service-and was followed by the Shortgrass Steppe Long-Term Ecological Research project. This volume is an enormously rich source of data and insight into the structure and function of a semiarid grassland.
