Figure 3. Calling song characters of the Tibicina OTUs from Sardinia and the known species from Corsica. Mean values per individual. A, syllable periods (SYP) vs. centre frequencies (N ind = 103). B, contribution of PP, NP and ISYD to the species-specific SYP (Nind = 103). C, two converse examples of temperature dependency of SYP (Nind = 19 resp. 23).
