This is both a practical handbook for experienced wildlife researchers and a textbook for graduate students in ecology and natural resource management programs. It presents methods for conducting experimental inference and mark-recapture statistical studies for fish and wildlife investigations. The data generated from the methodologies presented here are important today in light of the growing need for research on our environment and fish and wildlife populations. Techniques for Wildlife Investigations emphasizes the design of field studies and the statistical inferences that can be made from observed changes in animal abundance and populations. The information presented here is of value not only for wildlife management but also for social and economic decision-making related to the environmental effects of human activities on wildlife populations. Biologists, ecologists, biometricians, and fish and game managers will find this book invaluable in their work. This book provides the reader with quantitative criteria for designing effective field experiments; statistical methods for analyzing mark-recapture data; and examples and recommendations for implementing field studies.
