Fig. 3: Congruence in spatial association of global regionalizations among taxa at the species-level.
From: Global biogeographic regions for ants have complex relationships with those for plants and tetrapods
The V-measure (Vβ) is an area-weighted harmonic mean of homogeneity between two regionalization schemes, where higher values mean stronger spatial associations. Higher standardized effect size (SES) means that the similarity between the observed biogeographic structure of taxa on the row and column is higher than would be expected by random regionalizations of taxa on the column, with * indicating two-sided p value < 0.05. Comparisons based on the regionalization of ant genera show similar patterns, and details can be found in Supplementary Fig. 13.
