FIGURE 15. Calls A and B in Review of bioacoustical traits in the genus Physalaemus Fitzinger, 1826 (Anura: Leptodactylidae: Leiuperinae)

FIGURE 15. Calls A and B of Physalaemus crombiei. Oscillograms (A, C, D, E, F, K, and M) and audiospectrograms (B, G, H, I, J, L, and N). A single typical call A (A and B). Variant calls A with different number of pulses, pulse durations, and interpulse intervals (C–I). Last three pulses of the call A (F–J). Two B calls with different envelope and spectral features (K–N). Note that there is no silence intervals within call B (K–N). Horizontal scale bars have 0.1 s (C–E, G–I, M–N) and 0.05 s (F and J); vertical scale bars have 1 kHz. Filter bandwidth (Hz): 90.6 (G and J); 79.3 (B); 84.6 (I); 67.4 (L and N).
