Sex Ratios

IAN HARDY is Senior Research Fellow in Biological Sciences at the University of Sunderland. He has published more than 50 articles, about half of which focus on sex ratios, and currently serves as Consulting Editor for the journal Animal Behaviour.

' … this excellent book provides an up-to-date and critical review of the models and data relating to sex ratios. … well structured and demonstrated that a multi-authored book can be cohesive.' TRENDS in Ecology and Evolution
