Note: All analyses were conducted on the phylogenetically corrected and size-corrected residuals of the acoustic parameters [34]. Values obtained for genetic distances models derived from 12S mtDNA sequences are indicated in regular font, whereas values obtained for distance models derived from rhodopsin sequences are indicated in italics. One-tailed tests were conducted for all analyses, under the assumption that species that are genetically more related show more similar values for the acoustic parameters. Significance was estimated using a Monte-Carlo procedure, with 10,000 permutations. For Moran’s I, the values given are the standard deviates of Moran’s I statistic. Mantel r values correspond to the best-fitting model (which can be a multivariate trait distance) obtained using a stepwise forward procedure on the entire sample of 49 species. * P < 0.05, ** P < 0.01, *** P < 0.001.
