Bird’s synonym and nested chorotypes.

Species sharing biogeographical properties converge to synonym chorotypes, in which parameters, and spatial and taxonomic composition are mostly alike. Nested chorotypes are taxonomic subsets of a larger pattern. The patterns shown at Figs 4 and 5 (references species in bold) can be generated by other species grouped at their respective chorotypes. Usually the higher CS mean to all other members gives the name to the chorotype. The only exception is Heliodoxa xanthogonys, which here, for convenience, gives its name to the ‘Tepuis1’ pattern. This is the only presented chorotype with nested subsets (1.1, 1.1.1). For patterns at the Amazonian margins, not all species composing the groups (S1 Table) matched the criteria of inclusion, and were not analyzed as references (e.g, some Heliodoxa spp. chorotypes).
