Description / Table of Contents:
Anne Magurran's account of the evolutionary ecology of the guppy integrates historical breakthroughs with new research in this fast-moving field. She reveals how guppies provided some of the first evidence of sperm competition and sexual selection, and how they continue to inform scientific thought on mating systems and cryptic choice. The book also covers the consequences of variation in predation risk, the potential for ecological speciation, and conservationissues, among many other topics. This timely synthesis of research into a species that has raised key questions in evolutionary ecology will be of great interest to graduate level students as well as professional researchers in the fields of behavioural ecology and evolutionary biology.
