New Acoustic Biodiversity Index Correlates Strongly with Species Richness

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new Acoustic Biodiversity Index (ABI) that uses species-level sound detections to provide a more accurate measure of biodiversity than traditional energy-based acoustic indices. The ABI, particularly ABI_E, normalizes Shannon diversity by the expected regional species pool and has shown a strong correlation with actual species richness. This new index was tested using the BirdNET classifier on recordings from a savanna in Zimbabwe and zoo habitats in Abu Dhabi, demonstrating its effectiveness in distinguishing biodiversity levels and controlling for false positives.

    A richness-sensitive Acoustic Biodiversity Index from species-level detections: classifier benchmarking, false-positive control and validation against standard soundscape indices in an African savanna and an urban zoo

    arXiv:2610.42042v1 Announce Type: new Abstract: Acoustic indices are widely used as rapid proxies for biodiversity, but they summarise the distribution of sound energy rather than the species producing it and often track richness poorly. We revise and test an Acoustic Biodiversit…
