MATING CALLS OF THE IBERIAN MIDWIFE TOADS ALYTES OBSTETRIC ANS BOSCAI AND ALYTES CISTERNASII

ABSTRACT The mating calls of the Iberian midwife toads, A.o. boscai and A. cisternasii show clear differences. The calls of A.o. boscai have a shorter duration (104.8ms) and a lower fundamental frequency (1.33 kHz) than those of A. cisternasii (172.0 ms and 1.45 kHz), between 12° and 16°C. In both species signal duration was found to be influenced by temperature.
