From: Evolutionary history of ponerine ants highlights how the timing of dispersal events shapes modern biodiversity

A Species richness; B Overall dispersal network; C Current net diversification rates; D Mean biogeographic immigration ages. A Species richness based on stacked spatial ranges estimated as alpha-hulls from geolocalized occurrences. B Overall network of dispersal events across bioregions averaged across 1000 Biogeographic Stochastic Mapping (BSM) simulations of biogeographic histories based on a DEC + J model. Arrow width scaled to overall counts of dispersal events displayed on arrow tips. Node size scaled to bioregional richness displayed in each node. Counts of taxa encompassing multiple bioregions are split equally among them. See Supplementary Fig. S10 for details of dispersal network per geological epoch. C Mean net diversification rates as mean tip rates obtained from BAMM rate estimates combined with taxon ranges. Areas with more than two taxa are shown. D Mean biogeographic immigration ages as mean taxon biogeographic immigration ages combined with taxon ranges. Biogeographic immigration ages depict the timing of the first arrival of each taxon and its ancestral lineages in its current bioregion, as estimated from 1000 BSM simulations. Areas with more than two taxa are shown. Results for alternative divergence dating hypotheses are shown in Supplementary Fig. S23.
