An important first step in studying the demography of wild animals is to identify the animals uniquely through applying markings, such as rings, tags, and bands. Once the animals are encountered again, researchers can study different forms of capture-recapture data to estimate features, such as the mortality and size of the populations. Capture-recapture methods are also used in other areas, including epidemiology and sociology.
With an emphasis on ecology, Analysis of Capture-Recapture Data covers many modern developments of capture-recapture and related models and methods and places them in the historical context of research from the past 100 years. The book presents both classical and Bayesian methods.
A range of real data sets motivates and illustrates the material and many examples illustrate biometry and applied statistics at work. In particular, the authors demonstrate several of the modeling approaches using one substantial data set from a population of great cormorants. The book also discusses which computer programs to use for implementing the models and contains 130 exercises that extend the main material. The data sets, computer programs, and other ancillaries are available at www.capturerecapture.co.uk.
The book is accessible to advanced undergraduate and higher-level students, quantitative ecologists, and statisticians. It helps readers understand model formulation and applications, including the technicalities of model diagnostics and checking.
"This book hits its target audience perfectly. … an excellent basis for an advanced undergraduate course on capture-recapture methods, or by selecting sections of the book, part of a course on wildlife assessment and management methods … impressive in its scope and breadth … an excellent reference book for quantitative ecologists and statisticians … The book comes with an attractive and well-organised website containing resources that are a real bonus for anyone wanting to develop teaching material on capture-recapture or take advantage of the educational material there for their own understanding of the topics covered. I highly recommend the book to anyone interested in capture-recapture methods, particularly as they relate to ecological problems."

"This volume will be useful as both a textbook and reference, introducing readers to the most recent methodological developments in drawing inferences about animal population dynamics from the study of marked individuals. In a rapidly changing discipline, this book does a good job of surveying the current ‘art of the possible’."
—Jim Nichols, Patuxent Wildlife Research Center, U.S. Geological Survey
"Analysis of Capture-Recapture Data is an invaluable companion to the modern theory and practice of capture-recapture modelling. It is a text with multifaceted appeal, ranging in coverage from traditional models to cutting-edge developments, and flowing effortlessly from practical model-fitting advice to advanced technical topics such as parameter redundancy. It is presented throughout in a concise, accessible style that strikes an impeccable balance between illumination of concepts and succinct mathematical detail.
This book is a must-have for all statisticians working with ecological data and is also suitable for ecologists with a mild quantitative bent or as a course companion for students from senior undergraduate years onwards. The text can be used either as a dip-in reference or as a cover-to-cover read. Anyone who completes the latter can feel confident that they are up to date with everything that matters in this vibrant and expanding field."
