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.

The effect of latitude on the efficacy of acoustic indices to predict biodiversity: A meta-analysis

Ecological Indicators
The increasing biodiversity loss worldwide has resulted in a growing need for cost-effective, efficient tools to monitor biodiversity over large spatial and temporal scales.

Acoustic indices estimate breeding bird species richness with daily and seasonally variable effectiveness in lowland temperate Białowieża forest

Ecological Indicators, 2023
Acoustic indices have been proposed as rapid and easy to apply tool for biodiversity estimation of vocalising animals without the need for individual species identification.

Listening to a changing landscape: Acoustic indices reflect bird species richness and plot-scale vegetation structure across different land-use types in north-eastern Madagascar

Ecological Indicators, 2021
New technologies like ecoacoustic surveys promise time and cost efficiency for biodiversity assessments, serve as a basis for effective conservation policies, and are particularly appealing for remote and highly diverse tropical areas.

The relationship between acoustic indices, vegetation, and topographic characteristics is spatially dependent in a tropical forest in southwestern China

Ecological Indicators, 2022
The soundscape of different habitats can be discriminated by multiple acoustic indices as they have previously been related to vegetation characteristics.

Utility of acoustic indices for ecological monitoring in complex sonic environments

Ecological Indicators, 2021
With the continued adoption of passive acoustic monitoring as a tool for rapid and high-resolution ecosystem monitoring, ecologists are increasingly making use of a suite of acoustic indices to summarise the sonic environment.

Assessing the potential of acoustic indices for protected area monitoring in the Serra do Cipó National Park, Brazil

Ecological Indicators, 2021
Protected areas (PAs) monitoring is a technical bottleneck that limits the implementation of decision-making processes for natural resource and wildlife management.

Rapid coral reef assessment using 3D modelling and acoustics: acoustic indices correlate to fish abundance, diversity and environmental indicators in West Papua, Indonesia. [PDF]

PeerJ, 2021
Background Providing coral reef systems with the greatest chance of survival requires effective assessment and monitoring to guide management at a range of scales from community to government.

Predicting bird diversity through acoustic indices within the Atlantic Forest biodiversity hotspot

Frontiers in Remote Sensing, 2023
The increasing conversion of natural areas for anthropic land use has been a major cause of habitat loss, destabilizing ecosystems and leading to a biodiversity crisis.

Using acoustic indices in ecology: Guidance on study design, analyses and interpretation

Methods in Ecology and Evolution, 2023
The rise of passive acoustic monitoring and the rapid growth in large audio datasets is driving the development of analysis methods that allow ecological inferences to be drawn from acoustic data.
