Upstream solutions to prevent their impact, including their detection, are needed. Wasmannia auropunctata, an invasive ant living in vagile supercolonies, is especially hard to track and is a major threat for tropical ecosystems and local animal communities. As part of such tropical communities, crickets are sensitive to ecological conditions, easy to collect, detectable and identifiable through their species-specific calls. Here, we evaluated the use of an acoustic community of crickets as an indicator of the presence of W. auropunctata in New Caledonia. We evaluated the dominance of the crickets in the soundscape, describe the cricket community structure and diversity along a shrubland to forest gradient, characterize these cricket communities structure and diversity in the light of ongoing invasion by W. auropunctata, and identify cricket species' indicators of the invasion. Acoustic recordings collected on 24 sites were described using humanlistening and spectrographic visualization. The results demonstrated a clear dominance of the cricket group in the New Caledonian nocturnal soundscapes. Each habitat harbored a specific acoustic cricket community related to specific environmental attributes including vegetation height, daily variation of humidity and temperature. The presence of W. auropunctata was significantly associated with a lower cricket acoustic activity and species richness at night. Of the 19 species detected, four nocturnal species were identified as indicator of non-invaded forests and preforests. This work supports the use of acoustic as an alternative method to detect invasion. specialized Bioindicator Acoustic community Invasive species Soundscape Ecoacoustics NOUVELLE CALEDONIE 080 20 5 1099-1111 2018 1387-3547 https://www.documentation.ird.fr/hor/fdi:010072866 10.1007/s10530-017-1612-0 1387-3547 [F B010072866] https://www.documentation.ird.fr/hor/fdi:010072866 https://www.documentation.ird.fr/intranet/publi/2018/05/010072866.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2018-06-01 2023-07-11 fdi:010072866 fre
