Informationen zum Autor 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. Klappentext Theory and methods of exploring sex ratios in plants! animals and microbes. Zusammenfassung Sex ratios! the proportions of males and females in any given species! are important in evolutionary and behavioural ecology. This volume explores the context to and methods for many aspects of research on sex ratios! and will be an indispensable reference for all those working in this area.
