Molecular ecologists finally have a text-book that deals with their discipline. Ecological Genetics fills the market-gap between general accounts of evolutionary biology and specialist texts focusing on individual research topics. The authors have brought together a useful mix of theory, practical approaches, conceptual issues, and individual case studies to provide a balanced and accessible overview of the field. Peter Hollingsworth, Royal Botanic Garden "This book is a pleasure to read: it is clearly written, well organized and leaves no ambiguity." Andre A Dhondt, Cornell University, Trends in Ecology and Evolution, August 2004 "This book is a well-written, comprehensive overview of the essential techniques underlying ecological genetics. I would certainly recommend it to any new student undertaking postgraduate study in the field of molecular ecology." Dr. Jim Provan, Queen's University Belfast
Ecological Genetics addresses the fundamental problems of which of the many molecular markers should be used and how the resulting data should be analysed in clear, accessible language, suitable for upper-level undergraduates through to research-level professionals.
