If a frog calls in the forest: Bioacoustic monitoring reveals the breeding phenology of the endangered R ichmond R ange mountain frog ( P hiloria richmondensis)

Bioacoustic monitoring of the endangered Richmond Range mountain frog (Philoria richmondensis) in Australia's Gondwana Rainforests reveals that peak calling activity occurs during austral spring mornings and evenings, with ambient temperature (15–16°C) significantly influencing call frequency. A negative relationship between precipitation and calling activity was also observed. These findings provide a benchmark for detecting phenological shifts due to climate change and optimize future survey efforts by targeting periods of high acoustic detectability.
