Overview

This book on estimating abundance of populations concentrates on distance sampling, despite the fact that most current field studies for estimating abundance use such methods. For many years the line transect monograph by Burnham et al (1980) has been the ""bible"" on this topic. Now the same authors of that book, together with Dr Steve Buckland, have written this present book. It has been deliberately written for practising biologists in an exceptionally clear and relevant way. In particular, it develops line transect sampling more comprehensively and in greater detail and looks at recently developed point transect sampling methods and gives many clear examples. It should serve as a reference manual for all quantitative biologists and biostatisticians, as well as a wide range of other biologists, enabling the reader to determine appropriate survey design. A suite of computer programs, DISTANCE, described by the authors, prvoces comprehensive analyses and is available from the authors. This book should be of interest to population biologists; ecologists; wildlife biologists; and biological statisticians.
