Buntbarsche: Wie wirkt sich die Schwimmblase auf das Hörvermögen aus?

(PresseBox) (Wien, )
Die Schwimmblase dient bei Knochenfischen - Fische mit verknöcherten Skeletten - in erster Linie dem Auftrieb. Bei vielen Arten erfüllt sie zudem akustische Funktionen: Sie kann der Lautbildung und in zahlreichen Varianten der Verbesserung des Hörvermögens dienen. BiologInnen der Universität Wien um Friedrich Ladich haben nun erstmals bei Buntbarschen die Unterschiede in der Schwimmblasenmorphologie sowie deren Auswirkungen auf das Hörvermögen untersucht. Die Ergebnisse haben sie in der renommierten Fachzeitschrift PLoS ONE publiziert.

"Die Schallschwingungen werden entweder durch vordere Fortsätze oder durch eigene Knöchelchen ans Innenohr weitergeleitet", erklärt Biologin Tanja Schulz-Mirbach die Charakteristika von Schwimmblasen, die dem Hören dienen.
