Phylogenetic signal as estimated with K statistic for different range attributes. The P-value, based on the variance of phylogenetically independent contrasts relative to tip shuffling randomization, is provided in parenthesis. Asterisks indicate significant P-values: * P < 0.05; ** P < 0.005 (Bonferroni critical value for ten tests). Codes: Size, range size (log-transformed); maxLong and minLong, maximum and minimum longitude of ranges, respectively; maxLat and minLat, maximum and minimum latitude, respectively; LonC and LatC, longitude and latitude of centroids, respectively; avB, average size of the biogeographic provinces that partly or completely overlap with the species ranges (log-transformed); nB, number of biogeographic provinces that partly or completely overlap with the species ranges.
