FIGURE 50. Call A of Physalaemus gracilis. Oscillograms (A, C–G, and M–P) and audiospectrograms (B, H–L, and Q–T). A typical call A (A–B). Variant calls A with different envelopes and spectral features (C–T). Note the presence of subharmonics at the beginning or middle of the call (I, L, Q, and R). Horizontal scale bars have 0.5 s (C–L) and 0.2 s (M–T); vertical scale bars have 1 kHz. Filter bandwidth (Hz): 42.3 (B); 84.6 (K, L, and T); 74.6 (J); 55.2 (I and R); 69.0 (H and S); 61.4 (Q).
