Opis

We hope this book will make the bewildering variety of methods for estimat- ing the abundance of animal populations more accessible to the uninitiated and more coherent to the cogniscenti. We have tried to emphasize the fun- damental similarity of many methods and to draw out the common threads that underlie them. With the exception of Chapter 13, we restrict ourselves to closed populations (those that do not change in composition over the period(s) being considered). Open population methods are in many ways simply extensions of closed population methods, and we have tried to pro- vide the reader with a foundation on which understanding of both closed and open population methods can develop. We would like to thank Miguel Bernal for providing the St Andrews example dataset used frequently in the book; Miguel Bernal and Jeff Laake for commenting on drafts of the book; Jeff Laake for providing Figure 10.1; NRC Research Press for allowing us to use Figures 10.2, 10.3, 10.4, 10.5, 10.6 and 10.7; the International Whaling Commission for allowing us to use Figure 12.1; Sharon Hedley for providing Figures 12.1 and 12.2. D.L.B. is eternally indebted to Carol, Alice and Aidan for their support through writing the book, and for the many evenings and weekends that it has taken from them.

Recenzje

From the reviews:

"In a unified likelihood-based framework, this book provides an excellent updated introduction to closed population models. The authors also briefly address how the framework can be extended to deal with open populations.....In addition to intended readers in biology, ecology and statistics, this book will reach a wider audience in other disciplines as some closed models have been widely applied to other areas including epidemiology, health sciences, software reliability and census undercount estimation. I compliment the authors for this significant book and hope they will write another on open populations."

"This is a useful book. It provides a comprehensive, readable survey which should be of value to anyone who wants an introduction to the currently available methodology for estimating animal numbers."

International Statistical Institute, Short Book Reviews

"The great strength of this text is that all methods are described not just in the same book, but in the same statistical framework... The authors have gone to great lengths to explain the principles underlying every method, in easily accessible, nonspecialist language. This includes a single-sentence "key idea" at the beginning of every chapter, which is generally a succinct and pertinent introduction. Practitioners with little background in statistics will find these explanations particularly worthwhile, being all too-familiar with the "recipe"approach to statistical analyses...."Coherence for the cognoscenti" is possibly the book's greatest contribution. It unfolds like a well-written sonata, with every section echoing the underlying themes before letting rip with the detailed development. Its potential as a nursery for new research ideas should not be overlooked."

Journal of the American Statistical Association

"This would be a good reference book for bio-statisticians interested in problems of estimation of animal abundance." (T.J. Rao, Sankhya, Vol. 65 (2), 2003)

"This book introduces and surveys the various methods used to assess wildlife populations. ... This is a useful book. It provides a comprehensive, readable survey which should be of value to anyone who wants an introduction to the currently available methodology for estimating animal numbers. The book is well-written. ... Relevant free software is also available on the web in the form of an R Library of simulation and estimation functions for many of the advanced methods ... ." (C.D. Kemp, Short Book Reviews, Vol. 23 (1), 2003)

"This is the first book to provide an accessible, comprehensive introduction to wildlife population assessment methods. It uses a new approach that makes the full range of methods accessible ... . This book uses a single conceptual and statistical framework for all the methods. This makes understanding the apparently different methods easier ... . As the first truly up-to-date and introductory text in the field, this book should become a standard reference for students and professionals in the fields of statistics, biology and ecology." (T. Postelnicu, Zentralblatt MATH, Vol. 1002 (2), 2003)

This is the first book to provide an accessible, comprehensive introduction to wildlife population assessment methods. It uses a new approach that makes the full range of methods accessible in a way that has not previously been possible. Traditionally, newcomers to the field have had to face the daunting prospect of grasping new concepts for almost every one of the many methods. In contrast, this book uses a single conceptual (and statistical) framework for all the methods. This makes understanding the apparently different methods easier because each can be seen to be a special case of the general framework. The approach provides a natural bridge between simple methods and recently developed methods. It also links closed population methods quite naturally with open population methods.
The book is accompanied by free software on the web, in the form of an R library, allowing readers to get some "hands-on" experience with the methods and how they perform in different contexts - without the considerable effort and expense required to do this in the real world. It also provides a tool for teaching the methods, including a means for teachers to generate examples and exercises customised to the needs of their students.
As the first truly up-to-date and introductory text in the field, this book should become a standard reference for students and professionals in the fields of statistics, biology and ecology.
