Additional file 1: Table S1. The effect of ambient temperature on call properties. Simple linear regression models (a-j) evaluating the effect of ambient temperature on each of the 10 call properties. N = 24 for all models. P values ≤0.05 are marked in bold. Table S2. Basic statistics of the 10 call properties. The mean ± SE and the range of the 10 call properties. N = 24. Fig. S1. Illustrations of the acoustic properties of the advertisement call of male Z. prasinatus. (a) A section of the advertisement call that contains 3 types of notes: A, B and C. (b) The temporal properties of a type A note. (c) The power spectrum of a type A note showing the dominant frequency of the note (i.e., the frequency corresponding to the largest energy peak). (d) Spectrograms showing frequency modulation (FM) in a type A note: the dominant frequency was lower in the first pulse and increased to the highest in the max pulse and rapidly decreased in the final pulse.
