Fig. 2: Geographical patterns of threat in reptiles and other tetrapods in terrestrial regions.
From: A global reptile assessment highlights shared conservation needs of tetrapods
a, Distribution of reptile species that are threatened (critically endangered, endangered or vulnerable). b, Regions with disproportionate numbers of threatened species for each tetrapod class (areas for each class where the proportional threat in species diversity is at least twice the loss for the next-most threatened class). c, Loss of reptile phylogenetic diversity (PD) if all threatened species became extinct. d, Regions with disproportionate phylogenetic diversity loss for each tetrapod class (calculated as in b). Grey, areas with no threatened species (a, c) or regions in which no class is disproportionately threatened (b, d). Data are shown at a resolution of 50 km.
