Notice the main separation in three groups, related to Foraging strategy .

Looking from above (rotating the plot 90 degrees over the PC1), differences in diet composition become evident. Widely foraging lizards eating vertebrates (Varanus, Tupinambis and Heloderma) are grouped and separated from sit-and-wait foragers that also eat vertebrates, like Gambelia, Lialis and Anolis schypheus.
