The current literature on resource selection by animals is a maze of methodologies for data collection and interpretation. Field biologists are crying out for a guide through the labyrinth. This book aims to provide such a guide. It aims to give a clear and consistent framework for the study of how animals select their resources (food and habitat) by taking the reader through different types of study design. It is a valuable handbook for the field biologist, especially those concerned with the management and conservation of wildlife. The authors have clearly identified the need to pull together the diffuse literature, and biologists should improve their experimental design, methodology and analysis with this book This book should be of interest to population biologists, ecologists, wildlife managers, conservation biologists, fisheries managers and biostatisticians.
