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,

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

Quantifying the Soundscape: How filters change acoustic indices
Ecological Indicators, 2023 Monitoring biodiversity can be time consuming and costly. Automated recording units (ARUs) have rapidly emerged as an efficient and cost-effective tool for measuring biodiversity.

A Denoising Preprocessing Framework via Orthogonal Multi-Tap Null-Steering Beamformer Bank: Facilitating Target Signal Preservation Under Low SINR Conditions and Complex Soundscapes [PDF]
SensorsAcoustic indices are popular tools for rapid biodiversity assessment using passive acoustic monitoring recordings, yet anthropogenic sounds in human activity areas compromise their robustness. In this paper, we focus on the typical urban–rural soundscape,

Vegetation Structure Drives Seasonal and Diel Dynamics of Avian Soundscapes in an Urban Wetland [PDF]
PlantsUrban wetlands are acoustic hotspots where vegetation structure, hydrological dynamics, and anthropogenic noise interact, yet multi-season assessments of how vegetation influences avian soundscapes are limited.
