Impact of parameterization in multiple acoustic index comparisons: practical cases in terrestrial and underwater soundscapes

Remote Sensing in Ecology and Conservation, EarlyView.
Parameter choices in acoustic analyses (sampling frequency, FFT size and window overlap) strongly influence multivariate soundscape separation. Using terrestrial and coral reef recordings, we show that these settings can exaggerate or mask ecological differences, emphasizing the need for parameter sensitivity testing and transparent reporting in ...

The impact of mother's mental health, infant characteristics and war trauma on the acoustic features of infant‐directed singing

Infant Mental Health Journal: Infancy and Early Childhood, Volume 47, Issue 1, January 2026.
Abstract Infant‐directed singing (IDSi) is a natural means of dyadic communication that contributes to children's mental health by enhancing emotion expression, close relationships, exploration and learning. Therefore, it is important to learn about factors that impact the IDSi.

Predictions of southern migration timing in coastal sharks under future ocean warming

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Projected redistribution of marine species due to ocean warming may undermine current conservation efforts. Yet, there have been few studies on how ocean warming may alter migration timing. Across 5 years of acoustic telemetry data (2018–2022), we determined environmental drivers of southward migration timing for 6 migratory shark species from
