Mapping assemblage-level tip-based metrics
Spatial variation on assemblage-level transition rates (aTR), averaged
across 10,000 estimates, revealed high aTR in central Amazonia, and
northwestern and southern South America, and low aTR in northeastern
South America, and along the eastern portion of Andes (Fig. 5A).
Phylogenetic uncertainty in aTR was high in central Amazonia and central
Andes (Fig. 5B). We found high assemblage-level stasis time (aST) in
northwestern South America and Atlantic Rainforest, and low aST in the
western Andes, northeastern and central South America (Fig. 5C).
Phylogenetic uncertainty in aST was high in northern Amazonia and the
central-south Andes, and it was low in the northeastern Brazil and along
the eastern portion of Andes (Fig. 5D). Finally, we found high aLT in
north and northwestern South America, central Amazonia, and along the
eastern Andes, and low aLT in northeastern and southern South America
(Fig. 5E). Phylogenetic uncertainty in aLT was high in central Amazonia,
and in southern and western Andes (Fig. 5F).
