Franck Courchamp is a CNRS researcher in population dynamics at the University of Paris Sud, France. His research covers two connected areas: biological invasions and Allee effects, both carried out mostly from a conservation biology perspective. He focuses mainly on theoretical work, but his prolonged stays at the Scripps Institute of Oceanography San Diego, CA, and at the Department of Zoology of Cambridge University, UK have involved him in a wide range of studies and approaches, including field work on remote islands, isotopic analyses of trophic webs and analyses of African wild dog populations.

Ludek Berec is a researcher in theoretical ecology at the Biology Centre of the Academy of Sciences of the Czech Republic. His interests move between development and analysis of general population models aimed at understanding fundamental ecological processes, and of more focused, species-specific models addressing more applied issues. His two key interests are two-sex population dynamics and Allee effects.

Jo Gascoigne is an empirical ecologist, and a research lecturer in marine biology at the University of Wales Bangor. Her research covers two different areas, Allee effects in conservation biology and the role of physical processes in structuring marine ecosystems. Before going to North Wales, she did her PhD on Allee effects in marine invertebrates at the Virginia Institute of Marine Science in the USA.

"This book is easy to read and packed with interesting natural history and ideas. It provides a very comprehensive review of all kinds of studies on the Allee effect and I recommend this book, particularly for those unfamiliar with Allee effects."--Caz M. Taylor, Ecology

[The book] is topical, a reliable summary, and will be a useful guide to the increasingly large and complicated literature on an important and overlooked phenomenon. Probably the greatest contributions this publication makes are the compilation, in a single place, of the many species in which Allee effects have been documented and a complete bibliography of the primary literature."--The Quarterly Review of Biology
