Crespo, E.G., Oliveira, M.E., Rosa, H.C., & Paillette, M. (1989). Mating calls of the Iberian midwife toads Alytes obstetricans boscai and Alytes cisternasi. Bioacoustics, Volume 2 (1): 1 -9

 

Abstract: 

The mating calls of the Iberian midwife toads, A. o. boscai and A. cisternasii show clear differences. We calls of A. o. boscai have a shorter duration (104.8 ms) 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.
