The advertisement call of Melanophryniscus cambaraensis from FLONA SFP has an average duration of 18.8 seconds (SD = 6.51) and it is composed of segments A and B (Figure 3A–B). Part A is composed of 3–11 single modulated notes, each one composed of one pulse (of 0.02 seconds each), separated by long time intervals of 0.38 seconds (SD = 0.052). Call part B is an extremely long train of unmodulated pulses emitted at a rate of 35.8 pulses per second (SD = 3.1), with short time intervals (Mean = 0.02; SD = 0.002), and lasting from 9–32.2 seconds (Mean = 16.6; SD = 6.8) (Table 1). Peak frequency of both parts is quite similar being on average 2.2 kHz in part A (SD = 0.16) and 2.2 kHz in part B (SD = 0.17).
