Abstract Mittelmeerlaubfrösche (Hyla meridionalis) rufen in den Abendstunden von Dezember bis März (Teneriffa) im Laichgewässer. Paarungsbereite Weibchen wandern gezielt auf die rufenden Männchen zu. Hierzu genügt eine ausschließlich akustische Orientierung, wie Klangattrappenversuche zeigen. Mittels synthetischer Rufe wird gezeigt, daß die Weibchen in der Lage sind, sowohl zwischen unterschiedlich langen Lauten zu differenzieren, als auch zwischen solchen, die unterschiedlich viele Impulse bei sonst gleicher Länge enthalten. Freilandaufnahmen.
Female Mediterranean tree frogs which are ready to mate approach a loudspeaker, 2 metres distant, from which mating calls specific to the originate. Differentiation tests show which sound characteristics play a part in the acoustic orientation. Given a choice of natural mating calls, which have differring characteristics depending on temperature, the females show a preference for those calls with higher temperature characteristics. The females also react to electronically simulated mating calls. The reaction of the females to the synthetic mating calls also depends on the repetition rate of the impulses which build up the calls.
