简介
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 combinesthe theory, methodology and applications of ecological modelling. The new edition is an essential, up-to-date guide to a rapidly growing field.
