Fig. 3: Spatial distribution patterns of different diversity measures for flowering plants in China.
From: Spatial heterogeneity of extinction risk for flowering plants in China
The diversity measures are threatened species richness (TR, a), proportion of threatened species (propTR, b), species richness (SR, c), endemic species richness (ER, d), phylogenetic diversity (PD, e), and phylogenetic endemism (PE, f), respectively. The significance level of the degree of spatial clustering for different diversity measures are listed after each Moran’s I. Pointplots on the right are latitudinal (g, h), longitudinal (i, j), and altitudinal patterns (k, l) of TR and propTR, respectively, with the colored bars representing values of propTR (g, i, k) and TR (h, j, l) in counties (n = 2894 counties). Points between two dotted lines in each pointplot are the core latitudinal (g, h), longitudinal (i, j), and altitudinal (k, l) regions of TR and propTR, respectively. ρ is the correlation coefficient between different measures. Colors from blue to red reflect values of different diversity measures from low to high.
