Introduction

Since 1965 my research has been concentrated on the calls and calling behaviour of anurans. This interest initially arose from work on sound-producing fish.  Such fish use mechanism with different structures to produce the sound signals, but the signals themselves are simple and often quite similar. In contrast, frogs and toads all use the larynx as their basic vocal apparatus, but the calls they produce are complex and vary widely from one species to another. Furthermore, each species has several calls with particular biological significance. How is it, then, that anurans have species-specific calls despite the similarity in their vocal organs? This question gave rise to many other, special problems. My bioacoustic investigations were initially carried out at the Zoophysiological Institute of the Eberhard-Karls-Universität in Tübingen, and from 1970 on – after I was appointed full professor at the Rheinische Friedrich-Wilhelms-Universität at Bonn and became director of the Institute for Zoology that is located in the Poppelsdorfer Schloss (pictured).
It was not long until students became enthusiastic about this new research area, and made valuable contributions to it during their work towards Diplom and PhD degrees. Other coworkers joined my research group and carried out their own investigations. Quite a few of my young colleagues made a long-term commitment to such research, continuing it independently and making considerable contributions towards the solution of bioacoustic problems in anurans. Some colleagues were called to other universities where they founded their own study groups.
