Exploring nocturnal soundscapes in an Australian open forest system using acoustic indices
Fig 2
Non-metric multidimensional scaling of (a) Insect sonotype richness (Jaccard binary) and (b) indices interaction (acoustic activity (ACT), acoustic evenness (AEI), spectral entropy (Hf), soundscape saturation (Sm)) scaled composite index with Ružička distance) comparing Hidden Vale and Grandchester.
Points are labelled by survey site and coloured by reserve; ellipses were drawn using the within-reserve mean dissimilarity distance. Stress values are reported for each ordination, with small values indicating closer similarity.
