In this manuscript, we developed a set of metrics, the specific overrepresentation score (SOS) and the geographic node divergence (GND) score, which together combine ecological and evolutionary patterns into a
single framework and avoids many of the problems that characterize community phylogenetic methods in current use. The figure shows an example of GND scores for the New World flycatchers. The colour scale and symbol sizes are pro-
portional to GND for each node. Nodes labeled A through F correspond to major distributional shifts in flycatcher assemblages. For example, node labeled C has the highest GND score and this node separates the tyrant flycatchers
(Tyrannines and Myiarchines) from the Fluvicolines. The tyrant flycatchers
are primarily distributed in tropical lowland forests but extend to the surrounding savannas and southern North America; whereas the Fluvicolines inhabit colder and drier environments, and extend to the subarctic zones at the pole-
ward tips of South and North America.
