This CD-ROM provides the facts, abstracts and figures needed to build environmental models together with information on the environmental effects of chemical substances. The data has been rigorously selected from scientific journals covering 25 years. Environmental models included cover a wide range of topics, including eutrophication, dispersion of chemical compounds, growth and competition of different organisms as well as models which describe global environmental cycles. Ecotoxicological information on substances includes the water concentrations at which aquatic organisms are affected by the chemical compounds. These concentrations are used in the regulation of releases and for calculating safe concentration levels in the environment. The growth of environmental toxicological data and the growth of different types of environmental models has been a major new development in this field. ECOTOX: Ecological Modelling and Ecotoxicology presents ecotoxicological information about more than 2000 chemical substances, including such data as growth parameters, lethal concentrations (LC50), emissions, degradation of chemical substances, background concentrations, concentration factors, biological effects, octanol/water partition coefficients, excretion and uptake rates, emissions and composition of living organisms. Accompanying this information are the constants and equations to be used in environmental models, and abstracts from scientific journals to give an explanation concerning the scope of the data. All this information is directed towards environmental modelling, administration of environmental regulations, scientific models, environmental policy making and environmental impact assessment.NEW FROM APRIL 2001 - http://www.enviromod.subnet.dk/Ecological and Environmental Modeling - An Interactive Internet Course

This reference offers both a basic introduction and advanced technical details of available mathematical and computing methods for modeling sustainable development, closing an exisiting gap in this field, as well as illustrating their use through case studies and examples. The methods and case studies presented here are targetted at sustainable development, although they have a wide range of other applications, including economics, medicine and control systems.

The problems of interrelation between human economics and natural environment include scientific, technical, economic, demographic, social, political and other aspects that are studied by scientists of many specialities. One of the important aspects in scientific study of environmental and ecological problems is the development of mathematical and computer tools for rational management of economics and environment. This book introduces a wide range of mathematical models in economics, ecology and environmental sciences to a general mathematical audience with no in-depth experience in this specific area. Areas covered are: controlled economic growth and technological development, world dynamics, environmental impact, resource extraction, air and water pollution propagation, ecological population dynamics and exploitation. A variety of known models are considered, from classical ones (Cobb Douglass production function, Leontief input-output analysis, Solow models of economic dynamics, Verhulst-Pearl and Lotka-Volterra models of population dynamics, and others) to the models of world dynamics and the models of water contamination propagation used after Chemobyl nuclear catastrophe. Special attention is given to modelling of hierarchical regional economic-ecological interaction and technological change in the context of environmental impact.

The study of wetlands is a relatively new field and the modelling of these systems is still in its formative stages. Nevertheless, the editors felt compelled to assemble this volume as a first statement of the state of the art of modelling approaches for the quantitative study of wetlands. A global approach has been adopted in this book, not only by including a wide geographic distribution of wetlands, but also by including papers on both freshwater and saltwater wetlands. Wetlands are defined as systems intermediate between aquatic and terrestrial ecosystems, and include ecosystems under a wide range of hydrologic and ecologic conditions. The wetland types discussed in this book reflect that heterogeneity, ranging from intermittently flooded wet meadows to permanently flooded shallow reservoirs and lakes. Also included are modelling examples from coastal salt marshes, shallow estuaries, mesotrophic bogs, reedswamps, forested swamps, and regional wetlands. In summary, the book presents ecological modelling as a tool for management of these sensitive ecosystems, and for studying their structure and function. Each chapter has extensive references related to the modelling approach and wetland type discussed. It will be useful for wetland scientists and managers, and could also serve as a supplemental text on courses in wetland ecology.

This is a thoroughly revised and updated edition of an authoritative introduction to ecological modelling. Sven Erik Jørgensen, Editor-in-Chief of the journal Ecological Modelling, and Giuseppe Bendoricchio, Professor of Environmental Modelling at the University of Padova, Italy, offer compelling insights into the subject. This volume explains the concepts and processes involved in ecological modelling, presents the latest developments in the field and provides readers with the tools to construct their own models. The Third Edition features: . A detailed discussion and step-by-step outline of the modelling procedure. . An account of different model types including overview tables, examples and illustrations. . A comprehensive presentation of the submodels and unit processes used in modelling. . In-depth descriptions of the latest modelling techniques. . Structured exercises at the end of each chapter. . Three mathematical appendices and a subject index. This practical and proven book very effectively combines the theory, methodology and applications of ecological modelling. The new edition is an essential, up-to-date guide to a rapidly growing field.

The use of models to assess water quality is becoming increasingly important worldwide. In order to be able to develop a good model, it is necessary to have a good quantitative and ecological description of physical, chemical and biological processes in ecosystems. Such descriptions may be called ``submodels''. This book presents the most important, but not all, submodels applied in water quality modelling. Each chapter deals with a specific physical process and covers its importance, the most applicable submodels (and how to select one), parameter values and their determination, and future research needs.The book will be an excellent reference source for environmental engineers, ecological modellers and all those interested in the modelling of water quality systems.
