Based on a workshop held at the University of Bielefeld in Germany in March 1986, this book presents the work of researchers from a diversity of fields, from neuroanatomy to behavioural ecology, covering the anatomy, physiology and behavioural correlates of the auditory system in the vertebrate class amphibia. It summarizes all aspects of the amphibian auditory system, reviewing current knowledge of the structure, function and evolution of this sensory system, and offers new contributions to our understanding of this subject. Chapters discuss amphibian phylogeny, the anatomy and physiology of the peripheral auditory system, the anatomy and physiology of central auditory areas, specialized topics in sound localization, the development of the amphibian auditory system (including changes that occur during metamorphosis), acoustic communication in anurans, selected topics in the evolution of amphibian and vertebrate audition, and others aspects.
