Our latest #study explores the utility of acoustic indices in measuring biodiversity using data from 114 sites in #Cyprus, #China, and #Australia. Specifically, we evaluated the combined effectiveness of 60 acoustic #indices in measuring bird species richness using #machine #learning techniques.

Key findings:
•      The effectiveness of acoustic indices varies widely by region (e.g., R²: Cyprus = 0.06, China = 0.31, Australia = 0.52).
•      No single index was consistently effective across all regions, and only three indices worked in more than one region.
•      While useful for broader biodiversity surveys, acoustic indices may not yet provide the accuracy needed to monitor bird species richness effectively.
