Radio Tracking and Animal Populations

"This book is an important reference for any biologists' bookshelf." --SOUTHEASTERN NATURALIST (May 2006) "This book is a must reference for all scientist that work with telemetry or are contemplating telemetry projects. It should be used from start to finish...Academic Press is to be commended for continuing and updating its wildlife telemetry offerings." --THE CANADIAN FIELD-NATURALIST (2002) "...I have no doubts that this book will warrant a place in one's library, especially to assist graduate students in the design, planning, and delivery of radiotracking studies, as well as in the analysis or radiotracking data." --JOURNAL OF MAMMALOGY (February 2003) "...is a valuable book that should be of interest to a wide readership. ...I highly recommend this book for individuals conducting radiotelemerty studies." --Barry R. Noon for THE AUK (April 2002) "If I was embarking on a radio tracking study I would start with this book since it is concise in the basics, clearly highlights many potential pitfalls and stimulates deeper thinking about what can be achieved with tracking studies." --Jeremy Lindsell for IBIS (2002) "...wildlife biologists, managers and students seeking a laudable compilation of readable synopses will find exactly that...Various contributors have done an admirable job of placing methods in context with one another and distilling the fundamentals of relatively complicated statistical techniques." --Geln A. Sargaent, U.S. Geological Survey Northern Prairie Wildlife Research Center for ECOLOGY (2002)
