Westneat, D. F. and Fox, C. W. 2010. Evolutionary Behavioral Ecology. Oxford University Press.

​This edited book targeted for graduate students presents the foundational concepts in behavioral ecology and incorporates quantitative and molecular genetic perspectives. It includes both core hypotheses and controversies that shaped this field and describes new approaches that influence research today. The book reflects the primary role behavioral ecology has had in developing our understanding of the ecology of selection over the past 40+ years.
