From: Using citizen science to test for acoustic niche partitioning in frogs
(a) Spectrogram, oscillogram and power spectrum of sample frog call (Adelotus brevis) showing the various call parameters measured to determine acoustic similarity among calls of different frog species. (b) Map of records used for spectral overlap, PCAAll, PCASpectral and PCATemporal (red points, n = 1641), and dominant frequency distance (red and black points, n = 1854) analyses overlayed on Australia’s 7 ecoregions representing the different broad habitat types from which frog assemblages originate (TrFo = Tropical and Subtropical Moist Broaleaf Forests, TeFo = Temperate Broadleaf and Mixed Forests, TrGr = Tropical and Subtropical Grasslands, Savannas and Shrublands, TeGr = Temperatre Grasslands, Savannas and Shrublands, MoGr = Montane Grasslands and Shrublands, MeFo = Mediterranean Forests, Woodlands and Scrub, DeSh = Deserts and Xeric Shrublands).
