  abstract = {{T}ropical forests are biodiversity reservoirs but are increasingly fragmented by human activity, creating forest edges that alter microclimates and ecological dynamics. {U}nderstanding of edge effects is largely based on vegetation studies but still lacks faunal characterization. {H}ere, passive acoustic monitoring was conducted in {N}ew {C}aledonian forests to monitor faunal communities and to examine whether and how the distance from the forest edge structures the soundscape. {R}ecordings were collected at 30 sites located 10 to 300 meters from the edge, and 59 ecoacoustic indices were calculated. {R}epresentational similarity analysis with explainable feature-perturbation methods was used to assess relationships between acoustic patterns and edge distance. {A} low but significant relationship between distance to the edge and acoustic structure was observed at night between 22:00 and 04:00. {S}ix key indices were identified as most influential. {B}ased on these indices, nighttime soundscapes clustered into two groups: near-edge sites (from 10 to 40 m) and interior sites (from 100 to 300 m) were identified. {T}his threshold aligns with previously observed vegetation edge effects fading around 100 meters. {O}verall, the findings indicate that forest soundscapes can reflect edge effects on faunal activity and highlight the value of explainable, data-driven approaches in ecoacoustic research and biodiversity conservation.},
