About this book

This book develops thought-provoking applications which emphasize the value of modelling as a learning tool. Beginning with basic descriptive equations, matrix representations and consumer-resources interactions, the book then goes on to explore applications in simulation, scenarios, harvesting, population viability, metapopulation dynamics, disease outbreaks, vegetation stage and state dynamics, habitat suitability assessment, and model selection statistics. Detailed instructions are given on how to construct spreadsheet models, and programmes are written in True BASIC which forms a readily understandable foundation language. Throughout the book a wide range of examples are used relating to birds, fish, plants and large African mammals.

An accompanying CD provides models as well as a trial version of the True BASIC programming language.

An easy approach to modelling. (Mammalia, April 2009) "This is a very interesting text. ... The focus on method and theory as well as programming means that the text encourages the reader to question even basic assumptions." (Ecological and Environmental Education)
