Figure 6From: Habitat shifts in the evolutionary history of a Neotropical flycatcher lineage from forest and open landscapesAge estimates of Elaenia speciation events mapped onto the concatenated tree topology using a 2%/million years (MY) molecular clock rate; scale in MY; error bars at nodes refer to divergence range between taxa; neighboring nodes were merged in cases where both upper and lower divergence bound of one node falls inside the range of the neighbour; scale at bottom indicates millions of years before present.Back to article page
