  1. aMean and SD of dB values are computed using the seewave package [60]. bAutocorrelation function (ACF) index [43]. cTo calculate Moran’s I statistic, we used a binary matrix and defined as neighbours of the segment i all the segments in a buffer of length d around i with d ranging from 50 to 500 m with a step of 50 m. Only the highest values are reported here
