Is there a dialect in Pelodytes punctatus from southern Portugal

The mating call of Pelodytes punctatus from Algarve (Southern Portugal) is composed of two multipulsed motives, "a" and "b", lasting about 200 ms. One "a" is followed by two, three or more "b"s giving a sucession of "a-b-b-...". The inner timing in pulse rate acceleration distinguishes each motive. We suggest that the Algarve population has its own dialect, which is different from those of Camargue and Liguria, whose mating calls are longer (about 300 and 400 ms) with a syntax of "a-b" pairs. Pulse rates and durations change with temperature.
