Soundscape components inform acoustic index patterns and refine estimates of bird species richness
Frontiers in Remote Sensing, 2023 Ecoacoustic monitoring has proliferated as autonomous recording units (ARU) have become more accessible. ARUs provide a non-invasive, passive method to assess ecosystem dynamics related to vocalizing animal behavior and human activity.

Multidimensional terrestrial ecoacoustics assessment
, 2023 Ecologists faces challenges when analysing environmental acoustic data, such as handling big data, summarising and comparing long-duration recordings across regions and timescales. This thesis provide an innovative framework that combines time-series motif discovery and machine learning for analysing environmental sounds.

Ecological Management &Restoration, Volume 27, Issue 3, September 2026.ABSTRACT Water extraction for agriculture and human consumption, compounded by climate change‐induced weather events, has disrupted the natural flow regimes of river and wetland systems globally. These changes critically impact species dependent on wetland ecosystems.

Investigating the utility of ecoacoustic metrics in marine soundscapes [PDF]
Journal of Ecoacoustics, 2018 Soundscape analysis is a potentially powerful tool in ecosystem monitoring. Ecoacoustic metrics, including the Acoustic Complexity Index (ACI) and Acoustic Entropy (H), were originally developed for terrestrial ecosystems and are now increasingly being applied to investigate the biodiversity, habitat complexity and health of marine systems, with mixed ...

Transactions in GIS, Volume 30, Issue 6, September 2026.ABSTRACT Sound environments shape urban experience, yet conventional noise monitoring relies on isolated sensors lacking semantic context and spatial scalability. In this study, we develop a Vision‐Language Model for Soundscape (VLM4S), an exploratory, sensor‐free framework for inferring acoustic conditions from street‐view imagery.

SANE: An index of anthropogenic noise levels for wildlife research in terrestrial ecosystems
Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2464-2476, August 2026.Abstract Understanding the impact of noise pollution on wildlife is challenging due to the complexity of isolating the anthropogenic components from the soundscape. Soundscape studies usually employ acoustic indices that apply thresholds to isolate anthrophony from natural sounds. However, natural and anthropogenic sounds do not always conform to these

Impacts of a large hydroelectric dam on the Madeira River (Brazil) on floodplain avifauna
Acta Amazonica, 2021 Hydroelectric dams represent an important threat to seasonally flooded environments in the Amazon basin. We aimed to evaluate how a dam in the Madeira River, one of the largest tributaries of the Amazonas River, affected floodplain avifauna.

The Sounds of the Australian Summer: A Continental‐Scale Inventory of Cicada Ecoacoustics
Austral Ecology, Volume 51, Issue 8, August 2026.ABSTRACT Australia has a rich cicada fauna, with over 400 described species including some of the loudest‐calling species in the world. The males of each species produce a unique call for attracting females; these calls are invaluable for informing taxonomy and allowing for species‐level identification.

Forest degradation reduces acoustic partitioning in tropical avian communities
Journal of Avian Biology, Volume 2026, Issue 4, July 2026.The acoustic niche hypothesis posits that species partition acoustic space by frequency and time to avoid signal masking, and that any local loss of species leaves detectable gaps in co‐evolved soundscapes. However, loss, fragmentation and disturbance of habitat often lead to species turnover, and as sensitive species are lost, generalist species ...
