FIGURE 8. Oscillograms (upper graphs) and sonograms (lower graphs) of advertisement calls of Allobates tapajos recorded at the species type locality in Parque Nacional da Amazônia, Itatituba, Pará State, Brazil. (A) Ten seconds of continuous advertisement calls of a male (INPA-H 34402, SVL = 15.02 mm) recorded at 23.9 °C. Notes are predominantly arranged in consecutive note pairs split by slightly longer silent intervals. (B) Detailed view of two note pairs from the same call session, ascending frequency modulation is evident in the sonogram. (C) Advertisement calls of a second male (INPA-H 34423, SVL = 15.32 mm), also recorded at type locality at 23.9 °C, exemplifying variation in note arrangement (note several single notes scattered along call length). (D) Detailed view of the same call session demonstrating that spectral parameters of notes do not vary across distinct note arrangements.
