Systems Analysis and Simulation in Ecology, Volume I, is a book of ecology in transition from a ""soft"" science, synecology, to a ""hard"" science, systems ecology. It is an enthusiastic and optimistic statement about the fundamental adaptability of the scientific mechanism to newly appreciated truths of existence. It documents, in ecological science, a move away from the explanatory or cognitive criterion toward the predictive criterion, a hard one with the potential of leading ultimately to optimal design and control of ecosystems. The book is organized into three parts. Part I is an overview of some of the methods and rationales for ecological systems modeling for the purposes of simulation and systems analysis. It provides an elementary introduction to the use of analog and digital computers for simulation and a rationale for ecological model-building. Part II illustrates three different approaches to population modeling. These include a mathematical analysis of microbial (Chlorella, Selenastrum) dynamics in both continuous and batch cultures; and a bioenergetics study of the terrestrial isopod Armadillidium, utilizing concepts from control theory and the transfer function technique of classical dynamic analysis. Part III brings together a group of papers describing various aspects and philosophies of ecological simulation. These include common problems in ecosystem simulation and the question whether or not some of the newer methods of systems ecology might not be used in connection with some of the older data and observations of traditional synecology.

This book explores the theory and methods of systems analysis and computer modeling as applied to problems in ecology and natural resource management. It reflects the problems and conflicts between competing uses of limited space and the need for quantitative predictors of the outcome of various management strategies.

This 1980 book was a synthesis of much of the recent work on the functioning of grassland ecosystems at the time.

This book discusses the photosynthesis for ecosystem models, in particular the strengths and limitations of four methods used for predicting photosynthesis. The methods usage depends upon the purpose of the prediction to be made, as well as improvements in associated techniques that seem to revolutionize the methodology. Therefore comparisons between methods are valuable justifying this state of the art review for all photosynthetic scientists.

As part of the Environmental and Ecological Modeling Handbooks series, the Handbook of Ecosystem Theories and Management provides a comprehensive overview of ecosystem theory and the tools - ecological engineering, ecological modeling, ecotoxicology and ecological economics -to manage these systems. The book is laid out to provide a summary or survey of each topic, using many tables and figures. Concepts, definitions, important findings, basic hypotheses, important correlations between theories and observation with illustrative graphs are included. The comprehensive treatment of ecosystem theory and application of theoretical tools, and the integration of classical theory and real world examples, sets this book apart. It covers newly emerging topical areas as well as nontraditional topical areas (i.e. chaos) that will interest professionals trained in previous decades and enlighten those now entering into formal training. The general approach taken by the authors makes this an essential reference and handbook for professionals and students.

The virtual impossibility of extracting the many different species from a habitat with equal efficiency by a single method (e.g. Nef, 1960). 1.1 Population estimates Population estimates can be classified into a number of different types; the most convenient classification is that adopted by Morris (1955), although he used the terms somewhat differently in a later paper (1960). 1.1.1 Absolute and related estimates The animal numbers may be expressed as a density per unit area of the ground of the habitat. Such estimates are given by nearest neighbour and related techniques (Chapter 2), marking and recapture (Chapter 3), by sampling a known fraction of the habitat (Chapter 4-6) and by removal sampling and random walk techniques (Chapter 7). Absolute population The number of animals per unit area (e.g. hectare, acre). It is almost impossible to construct a budget or to study mortality factors without the conversion of population estimates to absolute figures, for not only do insects often move from the plant to the soil at different developmental stages, but the amount of plant material is itself always changing. The importance of obtaining absolute estimates cannot be overemphasized.

Theoretical Systems Ecology: Advances and Case Studies aims to relate systems ecology theory to theoretical systems ecologists and other theoreticians in systems science. The main language of systems theory is mathematics. This book somewhat simplifies concepts, advances, and developments of the field to non-mathematicians who lack background in some aspects of systems ecology. It presents examples after every chapter that shows the application of theory to the development and analysis of models. This book generally focuses on three problems. The first problem is the selection of components found in the system model. The definition of the relationships and interactions between the system variables is another concern of this book. It also looks into the model analysis. These problems are thoroughly discussed in each section of the book. The theory of modeling, formalisms, classes, and properties of models are covered in the first two sections of this book. A whole section in this book is dedicated to Systems Identification and deals mostly with the problem of extracting information from data. Other sections cover model analysis with focus on trends in some aspects, such as stability and control theory.

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.

Applied Systems and Cybernetics, Volume IV: Systems Research in Health Care, Biocybernetics and Ecology documents the proceedings of the International Congress on Applied Systems Research and Cybernetics. This volume compiles papers that present several concepts of health care and reflect thinking in this field. This book introduces various health care systems and models, and then tackles some issues on managing the long-term health care facility. A special information system for public health is also described in this volume. This text will be invaluable to those interested in systems research and its applications to a variety of fields, including health care.
