Sound Tracks Function

The claim

Acoustic diversity indices track functional diversity better than species richness, because signal structure reflects ecological role.

01Mechanism

Call structure is tied to body size and foraging mode, which are functional traits.

02Prediction

Acoustic indices should correlate with functional metrics.

03Refutation

Indices tracking richness alone would remove function.
