Effectiveness of acoustic indices as indicators of vertebrate biodiversity
Ecological Indicators, 2023 Effective monitoring tools are key for tracking biodiversity loss and informing management intervention strategies. Passive acoustic monitoring promises to provide a cheap and effective way to monitor biodiversity across large spatial and temporal scales,

Understanding acoustic indices as multi-taxa biodiversity and habitat quality indicators
Ecological IndicatorsAcoustic monitoring captures the sound of nature, revealing biodiversity patterns and underlying drivers. Acoustic indices are increasingly used to analyse obtained recordings, but studies show inconsistent performance of acoustic indices as biodiversity

Acoustic indices as proxies for biodiversity: a meta-analysis. [PDF]
Biol Rev Camb Philos Soc, 2022 ABSTRACTAs biodiversity decreases worldwide, the development of effective techniques to track changes in ecological communities becomes an urgent challenge. Together with other emerging methods in ecology, acoustic indices are increasingly being used as novel tools for rapid biodiversity assessment. These indices are based on mathematical formulae that

Acoustic indices fail to represent different facets of biodiversity
Ecological IndicatorsAcoustic indices are cost-efficient tools for monitoring acoustically active taxa. Despite their increasing popularity, their suitability as biodiversity proxies remains debated due to theoretical and practical issues. Existing research has predominantly

Monitoring Grassland Bird Communities with Acoustic Indices
BirdsSeveral researchers have tried to find relationships between acoustic indices and vocal animal communities to use acoustic indices as a passive monitoring method, as human-derived surveys are expensive, time-consuming, and suffer from observer bias ...

Biotic sound SNR influence analysis on acoustic indices
Frontiers in Remote Sensing, 2023 In recent years, passive acoustic monitoring (PAM) has become increasingly popular. Many acoustic indices (AIs) have been proposed for rapid biodiversity assessment (RBA), however, most acoustic indices have been reported to be susceptible to abiotic ...

Acoustic indices as proxies for bird species richness in an urban green space in Metro Manila. [PDF]
PLoS One, 2023 We assessed eight acoustic indices as proxies for bird species richness in the National Science Complex (NSC), University of the Philippines Diliman. The acoustic indices were the normalized Acoustic Complexity Index (nACI), Acoustic Diversity Index (ADI)
