Full description Our study addresses a critical gap in ecological research: the assessment of nocturnal environments, which remain under-represented in the scientific literature despite their ecological importance. This gap was first highlighted by Orlando Park in 1940, and more recently revisited by Kevin Gaston in 2019, who emphasized the need to reinvigorate research on nighttime ecology. In this study, we highlight the ecological significance of nocturnal environments-habitats that support a high diversity of vocal species across multiple taxonomic groups-making them particularly well-suited for biodiversity monitoring using acoustic methods. We employed passive acoustic monitoring across two conserved reserves and measured acoustic diversity using a suite of acoustic indices during periods of low (winter) and high (summer) acoustic activity. To validate these indices, we assessed their association with sonotype richness. Our results demonstrate that a specific index reflects seasonal variation in sonotype richness and have potential on following variation of acoustic diversity.
