Description
Jorge, Couto, and van Rensburg test whether sound indexes can stand in for night biodiversity in an Australian open forest. Night ecology is understudied because sampling after dark is hard. Recorders that listen nonstop offer a cheap, scalable fix. Indexes summarize the soundscape in numbers. The team checked them against hand-tagged insect call types, a proxy for diversity. Four indexes in interplay tracked call richness best.
Those were activity, evenness, spectral entropy, and saturation measures. Habitat comparisons based on indexes matched those from tagged calls. The match supports indexes as a rough diversity gauge. Night surveys could widen without huge tagging effort.
