Implication

Simulation and field evaluation demonstrates reliable biodiversity monitoring via community sound analysis in forest habitats, suggesting scalable noninvasive ecological appraisal.

Key Points

To develop and evaluate a noninvasive method for assessing animal biodiversity at the community level using automated acoustic indexes without requiring species identification.
Formulated alpha (acoustic entropy) and beta (temporal and spectral dissimilarity) acoustic diversity indexes and benchmarked them using 540 simulated acoustic communities.
Applied the acoustic indexes to field recordings collected from two closely spaced dry lowland coastal forests in Tanzania exhibiting different levels of disturbance.
Alpha acoustic entropy exhibited a logarithmic correlation with species richness, whereas beta diversity showed a linear relationship with the number of unshared species across simulated communities.
Field evaluation revealed lower acoustic diversity in the more disturbed Tanzanian forest alongside distinct community composition shifts between the two sites.
