Fig. 6

A represents the original advertisement call (OC), B illustrates the rising intonation version of OC, where the pitch of the sixth note was increased by 15% (OCP), C shows the modified version of OC, where the sixth note was replaced by the sixth note of an advertisement call from a sympatric anuran species, Quasipaa boulengeri (OQ), D presents the rising intonation version of OQ, with a 15% increase in the pitch of the sixth component (OQP), E demonstrates the altered version of OC, with the last note replaced by white noise (OW), F shows the rising intonation version of OW, with a 15% pitch increase in the sixth component (OWP). It is worth noting that the rising intonation in the last components (OCP and OQP) results in measurable alterations in the frequency spectrum profiles of the last components compared to their corresponding original versions (OCP vs. OC and OQP vs. OQ). However, only minor alterations of the last components were observed for OWP and OW.
