Fig. 1: Responses of acoustic indices to changes in abundance in simulated communities.

The association between the Acoustic Diversity Index, ADI (a, b), Acoustic Evenness Index, AEI (c, d), Bioacoustic Index, BI (e, f) and Acoustic Entropy, H (g, h) of constructed soundscapes and the number of individuals of a single species contributing to that soundscape for North American (left column) and European (right column) species. Shaded areas indicate ±1 standard error.
