Ecology and Evolution of Dung Beetles

Herausgegeben von Simmons, Leigh W.; Ridsdill-Smith, T. James

• Gebundenes Buch

Produktbeschreibung

First comprehensive volume of the ecology and evolution of this model organism since 1991.
Shows how knowledge of dung beetle ecology contributes to general theories of evolutionary ecology, community ecology, functional ecology and population biology.

---

This book describes the evolutionary and ecological consequences of reproductive competition for scarabaeine dung beetles. As well as giving us insight into the private lives of these fascinating creatures, this book shows how dung beetles can be used as model systems for improving our general understanding of broad evolutionary and ecological processes, and how they generate biological diversity. Over the last few decades we have begun to see further than ever before, with our research efforts yielding new information at all levels of analysis, from whole organism biology to genomics. This book brings together leading researchers who contribute chapters that integrate our current knowledge of phylogenetics and evolution, developmental biology, comparative morphology, physiology, behaviour, and population and community ecology. Dung beetle research is shedding light on the ultimate question of how best to document and conserve the world s biodiversity. The book will be of interest to established researchers, university teachers, research students, conservation biologists, and those wanting to know more about the dung beetle taxon.

Leigh Simmons was born and educated in the UK, and is currantly Professor of Evolutionary Biology at the University of Western Australia. His research interests lie in all aspects of reproductive biology, from the evolution of sperm form and function, to mate searching and courtship behaviour. James Ridsdill-Smith was born and educated in the UK but carried out all his research in Australia working for CSIRO Entomology. He has been developing biological and ecological solutions to various pest problems and 15 years involved in the biological control of dung with scarabaeine dung beetles.
