This book was developed from a workshop on the "Effective Use of Ecological Modeling in Management," held in Oak Ridge, Tennessee, on October 23-26, 2000. The workshop was sponsored by the Department of Defense's (DoD's) Strategic Environmental Research and Development Program (SERDP), the Army Research Of?ce, and the Engineering Research and Development Center of the Corps of Engineers as well as by the U. S. Department of Agriculture (USDA) Forest Service. It was hosted by the Department of Energy's (DOE's) Oak Ridge National Laboratory (ORNL). The organizing committee for the workshop included senior s- entists from ORNL,the USDA Forest Service,and the U. S. Army Corps of Engineers (ACE). The members of the steering committee were John Barko,Paul Bradford,Bill Goran,Jeff Holland,Russell Harmon,and Mike Vasievich. They helped guide the workshop to a useful product by sugge- ing topics, speakers, and participants. Workshop attendees included senior ecological modelers within the Forest Service,DoD,other federal and state agencies, universities, and the private sector together with ecologic- resource managers in the Forest Service, DoD, and other government and nongovernment agencies and organizations. The book never could have come to fruition without the dedicated efforts of Fred O'Hara in editing each of the chapters and making sure that the text was complete and accurate and that standard methods of expression and design were used in the text, references, tables, and ?gures. His careful attention to the details and to effective communication is appreciated. Many people helped in bringing the book to completion.

The goal of the book is to examine scientific advances since 2000 that may have increased understanding and options in three general areas related to hypoxia: Characterization the Cause(s) of Hypoxia. The physical, biological and chemical processes that affect the development, persistence and extent of hypoxia in the northern Gulf of Mexico. Characterization of Nutrient Fate, Transport and Sources. Nutrient loadings, fate, transport and sources in the Mississippi River that impact Gulf Hypoxia. Scientific Basis for Goals and Management Options. The scientific basis for, and recommended revisions to, the goals proposed in the Action Plan; and the scientific basis for the efficacy of recommended management actions to reduce nutrient flux from point and nonpoint sources. In addressing the state of the science, the book focuses on the strengths and limitations of the science in managing the Gulf hypoxia problem, including available data, models and model results and uncertainty.

The potential for humans to alter Earth's atmosphere has been recognized since the end of the 19th century when Arrhenius estimated that a doubling of atmospheric carbon dioxide could alter the atmospheric radiation balance and raise average global temperature. Today, atmospheric CO concentrations play an important part in the 2 climate-change debate. Sources and sinks of CO associated with land use can be 2 significant determinants of the rate and magnitude of atmospheric CO change. 2 Combustion of fossil fuels and the deforestation associated with land-use change both contribute CO to the atmosphere; in contrast, biological processes on land create 2 potential sinks for the excess CO . Thus, land-use change and associated biological 2 processes become important elements in assessments of future atmospheric CO 2 increase; land-cover properties also affect the Earth's albedo, which is a climate feedback.

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, Ecological Responses to the 1980 Eruption of Mount St. Helens 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.

With the use of ecological models, managers and decision makers can make sure that the ecological systems affected by their decisions are accurately represented. Unfortunately, the most relevant ecological science and modeling techniques are often not used because managers are not familiar with them or find them inappropriate for their circumstances. The authors of this volume hope to close the gap between the state of the art in ecological modeling and the state of the practice in the use of models as decision-making tools. It will serve as a readable introduction to modeling for people involved in resource management and will also review specific applications of interest to more experienced modelers. The first chapters detail several successful uses of ecological models in resource management. There are then five pairs of chapters addressing important issues in ecological modeling, including barriers to the use of modeling in decision making, evolving approaches in the field, effective use of data, the toolkit approach to management, and the various scientific and technological investments required for productive modeling. Ecologists and other scientists will learn how best to focus their research for practical, real-world applications, and resource managers and other practitioners will learn the most appropriate methods of understanding dynamic processes and making projections about the implications of their decisions.

This volume applies ecological principles and guidelines to understand past and current land use and land management; and more importantly, endeavors to promote more ecologically sound approaches to future land use and management decisions. The volume incorporates case studies from a wide variety of disciplines and perspectives. The case studies explore past and current land use decisions, on both public and private lands, and include practical approaches and tools for land-use decision-making. Perhaps the most important feature of the book is the linking of ecological theory and principle with applied land use decision-making - the theoretical and empirical are joined through concrete case studies of actual land use decision-making processes. In this volume, readers will find a statement of fundamental ecological principles that are relevant for land use planning and management, coupled with multiple in-depth explorations of the application of these principles in action. In addition, most case studies describe specific tools and approaches for incorporating endeavors to join fundamental ecological knowledge with cutting edge application in order to both educate and provide concrete guidance for decision-making. The intended audience is broad and multidisciplinary, from undergraduate and graduate level courses in environmental studies to professional land use planners. "Read this and Discover. Wisdom lies in these pages, a scarce and powerful attribute." from the Foreword by Richard Foreman.

A central goal of transportation is the delivery of safe and efficient services with minimal environmental impact. In practice, though, human mobility has flourished while nature has suffered. Awareness of the environmental impacts of roads is increasing, yet information remains scarce for those interested in studying, understanding, or minimizing the ecological effects of roads and vehicles.

"Road Ecology" addresses that shortcoming by elevating previously localized and fragmented knowledge into a broad and inclusive framework for understanding and developing solutions. The book brings together fourteen leading ecologists and transportation experts to articulate state-of-the-science road ecology principles, and presents specific examples that demonstrate the application of those principles. Diverse theories, concepts, and models in the new field of road ecology are integrated to establish a coherent framework for transportation policy, planning, and projects. Topics examined include: -foundations of road ecology -roads, vehicles, and transportation planning -vegetation and roadsides -wildlife populations and mitigation -water, sediment, and chemical flows -aquatic ecosystems -wind, noise, and atmospheric effects -road networks and landscape fragmentation
"Road Ecology" links ecological theories and concepts with transportation planning, engineering, and travel behavior. With more than 100 illustrations and examples from around the world, it is an indispensable and pioneering work for anyone involved with transportation, including practitioners and planners in state and province transportation departments, federal agencies, and nongovernmental organizations. The book also opens up an important new research frontier for ecologists.
