Description of Phyllomedusa b. bahiana vocalizations

Two different types of vocalizations were recorded during the fieldwork: advertisement call ( Figure 3 ) and territorial call ( Figures 4 and 5 ). The acoustic parameters are presented in Table 2.

and territorial calls. Values are presented as mean ± standard deviation (amplitude).

Components = triads, double pulses and single pulses.

Advertisement call. The two males (MZUEFS 1512, SVL = 69.15 mm, and other male not captured) recorded for this part of the study were not visibly interacting with other males. The advertisement call was a monophasic call formed by one note with 12­16 pulses arranged in 4–5 groups of three pulses, called here as triads, and with or without one single pulse interspersed between triads or at the end of the call ( Table 2, Figure 3 ). The interval between calls was very irregular ( Table 2). All calls presented two peaks of intensity ( Figure 3C ) and the dominant frequency was about 0.96 kHz ( Table 2, Figure 3b and c ) that correspond to the first peak. However, in 27,3% of calls of the SUEFS 7.6 the dominant frequency changed to the second peak of intensity, showing values between 1.412 to 1.938 kHz (1.54±0.20; n=6) .

Territorial call. This call was recorded from a single specimen (MZUEFS 1809, SVL = 68.5 mm) calling in duet with another male on a neighboring tree, and a couple in amplexus was nearby on the ground. The territorial call presented two types: monophasic ( Figure 4 ) and diphasic ( Figure 5 ). The monophasic type is formed by one note with 14 –16 pulses arranged in one double pulse, four triads and one or two single pulses at the end ( Figure 4A ). The diphasic type is formed by two notes ( Figure 5 ). The first note is shorter than the second. The first note is comprised of 15–17 pulses arranged in one double pulse, one triad, 3–4 double pulses, and 3–4 single pulses at the end. The first double pulse and triad have a tendency to form a five­part pulse. The second note is formed by 15–16 pulses arranged in a double pulse, four triads and one or two single pulses and emitted faster than the first note. The second note of the diphasic call is very similar to the note of the monophasic call, but the triads of the latter have a tendency to be separated in double pulses plus a single pulse. The monophasic type is more frequently emitted than diphasic.

Phyllomedusa b. burmeisteri ­ advertisement call from RJ. The call duration, interval between calls, number of notes, pulse duration, interval between pulses and dominant frequency of advertisement call of one male from Rio de Janeiro, analyzed by Abrunhosa & Wogel (2004) in Avisoft­Sonograph Light I demonstrate the same results when analyzed in Canary 1.2.4 (present work) .

In addition, we present the pulse rate (pulses/second). The short call has 45.12 to 49.08 pulses/s (47.26±1.07) and the long call 45.29 to 47.64 pulses/s (46.09±1.34).
