Informationen zum Autor Dr Robert 'Bob' Wootton was Reader in Ecology at the Institute of Biological, Environmental and Rural Sciences, Aberystwyth University, UK. Bob's research addressed the ecology, behaviour and evolutionary biology of fishes. Dr Carl Smith is a Lecturer in the School of Biology at the University of St Andrews, UK and also holds a research position at the Institute of Vertebrate Biology of the Czech Academy of Sciences in Brno, Czech Republic. Carl's research focuses on mating system evolution in fishes. Klappentext Reproductive Biology of Teleost Fishes is the first integrated review of the reproductive biology of the bony fishes, which are the most species-rich and diversified group of vertebrates. Teleosts display remarkable variation in their modes of reproduction, and this volume is intended to provide a framework for understanding the remarkable reproductive diversity of this group. It describes their reproductive biology using, wherever possible, phylogenetic analyses and life-history theory as a means to interpret the information. The book addresses the genetic, physiological, behavioural, ecological, evolutionary and applied aspects of teleost reproduction in a comparative framework that emphasises the adaptive basis of reproductive diversity. Reproductive Biology of Teleost Fishes provides a comprehensive synthesis of fish reproduction that will be of great interest to life scientists, particularly ecologists, evolutionary biologists, physiologists and advanced undergraduates, postgraduates and research workers requiring a comprehensive overview of fish reproduction. The book is suitable for courses in fish biology and ecology, reproductive physiology and reproductive genetics. It also addresses applied questions and will be of value for courses on fisheries science and aquaculture. Libraries in all universities and research establishments where biological sciences, fisheries science and aquaculture are studied and taught should have several copies of this important book on their shelves. Zusammenfassung * Provides a thorough understanding of how fish reproduce * Vital source of information for those studying wild fish populations and also in aquaculture systems where successful reproduction is a core element of commercial success in fish breeding .
