Description / Table of Contents:
Ideal for researchers and natural-resource managers, this book explores new research and novel perspectives on 'sources and sinks' - a powerful framework for conceptualizing the population dynamics of animals, plants and microorganisms. It presents the latest advances in source-sink theory, methods and applications for sustaining natural resources and biodiversity.
