Available in PDF, EPUB and Kindle. Book excerpt: Environmental Sciences and Applications, Volume 6: Handbook of Environmental Data and Ecological Parameters presents the biological effects of chemical compounds and the physical environment. This book provides a list of the most important compounds from an environmental point of view. Organized into seven parts, this volume begins with an overview of the living organisms in the natural environment. This text then explores the ecosphere, including the element cycles and general properties of chemical compound in the ecosphere. Other parts consider the biological half life time of various chemical compounds and present the toxicological data of specific importance to environmental problems. This book discusses as well the chemical compounds that are related to species. The final part deals with the dynamics of environment and contains equilibrium data, which is often the point of departure for a dynamical description. This book is a valuable resource for chemists, biologists, ecologists, scientists, and research workers.
Download or read book Modelling in Ecotoxicology written by S.E. Jorgensen and published by Elsevier. This book was released on 2013-10-22 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology is the science of toxic substances in the environment and their impact on living organisms. Today we use many more chemicals in everyday life than we did 30-40 years ago. Our knowledge of the fate and effect of such chemicals in the environment has not yet followed the rate of chemical innovation in spite of our expanding knowledge of ecotoxicology. About 50,000 different chemicals are produced on an industrial scale, but we have only sufficient data to evaluate the environmental consequences of a few per cent of these. The need for ecotoxicological knowledge has never been more pronounced than it is today. Even more resources must be allocated in this field in the near future, if we are to be able to cope with the threat of more toxic chemical compounds in our environment.This book outlines the state of the art of modelling the fate and effects of toxic substances in the environment. Modelling in ecotoxicology differs from modelling in other fields by the great lack of data. The quality of the models is very dependent on the parameters used, and as we do not have a wide knowledge of parameters in ecotoxicological processes, good parameter estimation methods are crucial for ecotoxicolocal models. A comprehensive review of available parameter estimation methods is therefore included in this volume. Model examples and case studies have also been included to illustrate the difficulties and short comings in practical modelling.
Download or read book Developments in Environmental Modelling written by S.E. Jorgensen and published by Elsevier. This book was released on 2016-04-20 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: State-of-the-Art in Ecological Modelling covers the proceedings of the Conference on Ecological Modeling, held in Copenhagen, Denmark from August 28 to September 2, 1978. The book focuses on ecological modeling, particularly prey-predator models, lake and river models, toxic substances models, and holistic approaches to ecological modeling. The selection first discusses review presentations of ecological modeling, including river models, prey-predator models, application of graphical methods, and lake models. The application of microcosms in ecological modeling; water quality and irrigation in agriculture models; and distribution and effect of toxic substances models are also elaborated. The text then takes a look at the models of sea and coastal areas, atmospheric pollution, ecosystems in the lithosphere, and water management. The book surveys multi-species of planktons and nutrients model of lake eutrophication and modeling of vertical temperature distribution and its implication on biological processes in lakes. Topics include mathematical expression of multi-species of planktons and nutrients model in lake ecosystem; observation data on water quality and planktons; and models for vertical temperature distribution. The selection is a dependable reference for readers wanting to dig deeper into ecological modeling.
Download or read book ECOTOX written by L.A. Jørgensen and published by Elsevier. This book was released on 2012-12-02 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Wetland Modelling written by W.J. Mitsch and published by Elsevier. This book was released on 2012-12-02 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Fundamentals of Ecological Modelling written by Sven Erik Jørgensen and published by Elsevier Publishing Company. This book was released on 1986 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Very few books have been published to-date which provide an introduction to the topic of ecological modelling. Although many have been published on ecological modelling itself, it was necessary for the reader to already have an understanding of the field, or at least some experience in the development of ecological models, in order for him/her to be able to make full use of them. This easy-to-understand book aims to bridge this gap. The reader needs only an understanding of the fundamentals of environmental problems and ecology, although it is assumed that he/she has a fundamental knowledge of differential equations and matrix calculations. This monograph provides on the one hand an overview of the field and on the other an opportunity for the reader to develop his/her own models. The book discusses the modelling procedure in detail and gives a step-by-step presentation of the development of models. Advantages and shortcomings of each step are discussed and simple examples are used to illustrate all the steps. Most model types are presented by use of theory, overview tables on applications, complexity, examples and illustrations. Both simple and complex models are described.

Download or read book Models for Ecological Data written by James S. Clark and published by Princeton University Press. This book was released on 2020-10-06 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: The environmental sciences are undergoing a revolution in the use of models and data. Facing ecological data sets of unprecedented size and complexity, environmental scientists are struggling to understand and exploit powerful new statistical tools for making sense of ecological processes. In Models for Ecological Data, James Clark introduces ecologists to these modern methods in modeling and computation. Assuming only basic courses in calculus and statistics, the text introduces readers to basic maximum likelihood and then works up to more advanced topics in Bayesian modeling and computation. Clark covers both classical statistical approaches and powerful new computational tools and describes how complexity can motivate a shift from classical to Bayesian methods. Through an available lab manual, the book introduces readers to the practical work of data modeling and computation in the language R. Based on a successful course at Duke University and National Science Foundation-funded institutes on hierarchical modeling, Models for Ecological Data will enable ecologists and other environmental scientists to develop useful models that make sense of ecological data. Consistent treatment from classical to modern Bayes Underlying distribution theory to algorithm development Many examples and applications Does not assume statistical background Extensive supporting appendixes Lab manual in R is available separately
