First description of the acoustic repertoire, of Rana italica (Anura, Ranidae)


, : First description of the acoustic repertoire, of Rana italica (Anura, Ranidae). Herpetological Journal 16(2): 229-231

Vocalizations of Rana italica from six adult males were obtained from Torrente Gentile, a small brook located in the Torrente San Siro basin, Santa Margherita Ligure (Northern Italy). All signals were propagated from the bottom of shallow pools and were inaudible in air. Two common and one rare call type were documented. All calls were short, low amplitude signals. The most common call is frequency modulated, harmonically rich and the other two are not. None exceed 0.26 s. Our study confirms that males call underwater. This is consistent with the conclusion that it has an underwater mate recognition system.

The extent of cross-clade conservation of HIV oligomannose glycans is therefore a critical consideration for the development of HIV prophylaxes. W...
