Bioakustik und Echoortung

Dr. Annette Denzinger 

Prof. em. Dr. Hans-Ulrich Schnitzler


Wir untersuchen die Echoortung von Fledermäusen und Delfinen und das

akustische Kommunikationsverhaltenvon Wirbeltieren mit der Hypothese, dass diese in der Evolution an habitat- und artspezifische Aufgaben angepasst wurden.
Das Echoortungsverhalten der Fledermäuse steht dabei im Mittelpunkt.

 

Habitat, Nahrungstyp und Jagdmethode bestimmen die Ortungsaufgaben von Fledermäusen. Im Laufe der Evolution entwickelten die etwa 1000 echoortenden Arten ein artspezifisches Repertoire von Signaltypen und Verhaltensweisen, die an die jeweiligen Ortungsaufgaben angepasst sind und somit die Einnischung spiegeln. In einer rückgekoppelten Aktions-Perzeptions-Schleife senden die Fledermäuse fortwährend Ortungslaute aus, analysieren und bewerten die in den rückkehrenden Echos enthaltene Information, bilden eine Repräsentation der beschallten Welt und wählen dann die Laute aus ihrem Repertoire aus, die am besten geeignet sind, um das intendierte Verhaltensziel zu erreichen.

Wir erfassen, analysieren und vergleichen das Ortungsverhalten von Fledermäusenim Labor und im Freiland, um die Anpassung an unterschiedliche Ortungsaufgaben innerhalb einer Art und an nischenspezifische Aufgaben zwischen den Arten zu verstehen.
