Wie Grashüpfer-Männchen ihre Balzgesänge tunen

Evolutionsbiologen der Universität Bielefeld untersuchen, wie Insekten auf Umweltveränderungen reagieren

(PresseBox) (Bielefeld, )
Heuschrecken-Männchen, die Verkehrslärm ausgesetzt sind, singen in höheren Frequenzen als Artgenossen in ruhigen Gebieten. Das zeigten Bielefelder Forscher vor einem Jahr in einer Studie. Jetzt fand das Team heraus: Die Fähigkeit hochfrequent zu zirpen hängt nicht allein vom Erbgut ab, sondern bildet sich auch abhängig vom Lärmpegel im Lebensraum der heranwachsenden Tiere aus. Die neue Studie wurde jetzt im Fachmagazin Functional Ecology publiziert.

Die Studie vor einem Jahr gab keinen endgültigen Aufschluss über die biologischen Mechanismen, mittels derer die Tiere die beobachtete Frequenzverschiebung bewerkstelligen.
