Fig. 2: Global patterns of within-assemblage maximum speciation rates and speciation rate variability for amphibians at a 1 × 1° resolution.
From: The latitudinal variation in amphibian speciation rates revisited
a Map showing the distribution of fastest speciation rates estimated for each grid cell. b Speciation rate heterogeneity inferred from the coefficient of variation among the tip-level rates computed for all the species constituting each assemblage.
