Analysis of Ecological Systems: State-of-the-Art in Ecological Modelling


Book Description

The International Society for Ecological Modelling (ISEM) sponsors conferences, workshops and training courses with the aim of advancing the development of ecological and environmental modelling. The 3rd International Conference on the state-of-the-art in ecological modelling was sponsored by the ISEM in cooperation with the National Park Service Water Resources Laboratory and hosted by the Natural Resource Ecology Laboratory at Colorado State University. Its theme was the application of ecological modelling to environmental management and this book contains the full texts of the three invited papers presented in the five general sessions, plus the final summaries and syntheses of the topics covered during those sessions.




Modelling Complex Ecological Dynamics


Book Description

Model development is of vital importance for understanding and management of ecological processes. Identifying the complex relationships between ecological patterns and processes is a crucial task. Ecological modelling—both qualitatively and quantitatively—plays a vital role in analysing ecological phenomena and for ecological theory. This textbook provides a unique overview of modelling approaches. Representing the state-of-the-art in modern ecology, it shows how to construct and work with various different model types. It introduces the background of each approach and its application in ecology. Differential equations, matrix approaches, individual-based models and many other relevant modelling techniques are explained and demonstrated with their use. The authors provide links to software tools and course materials. With chapters written by leading specialists, “Modelling Complex Ecological Dynamics” is an essential contribution to expand the qualification of students, teachers and scientists alike.




The Water-Energy-Food Nexus


Book Description

The Water-Energy-Food Nexus: Optimization Models for Decision Making covers the discussion about water, energy, and food as a crucial resource for human well-being and for sustainable development. These resources are inextricable interrelated, therefore, to cover water, energy, and food demands in different sectors and at different scales, it must be considered several sources to produce resources even conventional or unconventional, and there must be considered the interlinkages of resources for a proper integration. This book will emphasize several issues that must be considered in the design of water-energy-food nexus systems such as the selection of technologies to produce water or energy, size of technologies and food required to cover nutritional demands. Therefore, in The Water-Energy-Food Nexus: Optimization Models for Decision Making, mathematical models are presented for the design of water-energy-food nexus systems involving several strategies to account for issues like sustainable development, security of resources, interest in conflicts from stakeholders, and efficient allocation of resources. - Includes different optimization models for the integration of water-energy-food nexus - Considers sustainability criteria in the presented models - Helps readers understand different approaches for trade-off solutions - Presents general software that can be used in solving different problems




Participatory Modelling for Resilient Futures


Book Description

Participatory Modelling for Resilient Futures: Action for Managing Our Environment from the Bottom-Up, Volume One provides an important contribution to environmental management by introducing an integrative framework for participatory research for better land use and natural resource planning, organized around compelling recent case studies. It is a valuable guide for the increasing number of students looking for solutions in sustainability science and also practitioners who are on the ground working with local communities to improve specific places. The book was developed in response to the need to provide a clear and synthetic account, in accessible and non-technical language, of the way in which innovative integrative research can help solve real world human-environment interaction problems at a range of levels and scales, e.g., participatory modelling to secure a sustainable future for a natural protected area, working with stakeholders to break the deadlock on renewable energy implementation in Europe or tackling social exclusion and reducing food carbon footprint through local agroecology schemes. - Makes modeling approaches accessible so environmental and natural resource managers can make more precise decisions, accounting for a positive and negative impacts of ecosystem changes - Provides recent real cases to demonstrate implementation of the concepts, allowing the reader to see how to bridge scientific research and societal needs in order to effectively translate knowledge into action - Provides an integrated perspective incorporating science, politics and society, as well as a toolbox of methodologies to enhance participation and engagement of key stakeholders




Developments in Environmental Modelling


Book Description

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.




Water Quality Modeling


Book Description

This volume represents the first decision support book aimed at water quality management for lakes and reservoirs. The book offers both a retrospective view (in terms of summarizing past work) and a prospective view (in terms of forecasting the greater use of such models as part of much needed environmental decision support systems). The concepts of lake and reservoir simulation modeling, as well as the concepts of decision support systems, formalized within the information systems discipline, are supported by a wealth of case studies. Case studies in the early chapters concentrate more on the physical (dynamic and thermodynamic) parameters, while later chapters stress the need for a more detailed representation of the biology and chemistry. Other case studies emphasize the management use of the model. New tools and concepts are also presented to facilitate the transfer of case studies presented in this volume from the arena of research to that of operational and planning management. Water quality managers, research scientists, and water engineers will find this volume an exciting source of new ideas and concepts.




Integration of Ecosystem Theories: A Pattern


Book Description

The book integrates for the first time existing ecosystem theories and is therefore able to present a full ecological and theoretical pattern. It shows that we are able to understand ecosystems and their reactions, provided that we use all basic systems ecology for different aspects of ecosystem properties. The first edition of this book was published in 1992. This second edition contains the many recently published and presented contributions on ecosystem theories, which show even more strongly that an integration of the existing ecosystem theories is needed and also possible.




Integrated Pest Management On Rangeland


Book Description

Grasslands comprise the largest and most diverse set of ecosystems in the United States and are among the most extensive in the world. Characterized by scanty rainfall, these western grasslands are too dry for crop production and are used almost exclusively for grazing livestock. The grasslands on the western edge of the Great Plains, known as the




Numerical Ecology


Book Description

The book describes and discusses the numerical methods which are successfully being used for analysing ecological data, using a clear and comprehensive approach. These methods are derived from the fields of mathematical physics, parametric and nonparametric statistics, information theory, numerical taxonomy, archaeology, psychometry, sociometry, econometry and others. Compared to the first edition of Numerical Ecology, this second edition includes three new chapters, dealing with the analysis of semiquantitative data, canonical analysis and spatial analysis. New sections have been added to almost all other chapters. There are sections listing available computer programs and packages at the end of several chapters. As in the previous English and French editions, there are numerous examples from the ecological literature, and the choice of methods is facilitated by several synoptic tables.




Biomass Production by Fast-Growing Trees


Book Description

Even though most of the biomass of the planet is in forests, we live in a world where wood as a raw material and its products are increasingly scarce. This is particularly so in important areas such as the European Community, which is far from self-sufficient in terms of wood. In recent years the need to intensify forest production and, in some cases, to uti lize abandoned agricultural land for forestry has focussed world-wide attention on the economic importance of fast-growing tree plantations. These are usually managed as short "rotations" (growing cycles) of less than 15 years, often for the production of industrial raw materials or biomass for energy. Under the designation of fast-growing tree plantations, or short rotation silviculture, one may find ecosystems managed for different economic objectives, with different intensities of technical intervention and different levels of productivity. They may include any of a wide range of species grown under various environmental conditions. A common factor, however, is the greater possibility that exists, relative to conventional forestry, for manipulation of both the environment and the genetics of the trees.
