Brazilian Redbelly Toad

description

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 3 A – 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) (Table 1).

We collected acoustic data of male calls in three different sample sites in Rio Grande do Sul, Brazil (Figure 1). We recorded Melanophryniscus cambaraensis during day and night on September 18 and 19 of 2012 in Floresta Nacional de São Francisco de Paula – FLONA SFP – a conservation unit (29 ° 25 ’ 41.3 ” S, 50 ° 23 ’ 44.5 ” W / 866 m asl) located in the municipality of São Francisco de Paula.

discussion

Comentarios: CAORSI et al. (2020: 218) no hallaron diferencias significativas en los parámetros bioacústicos de los cantos de anuncio entre Melanophryniscus cambaraensis y M. macrogranulosus. Se hace necesario contrastar datos morfológicos y moleculares para determinar si se tratan de especies distintas o no.
