Fig. 4: Event counts across bioregions.

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

Fig. 4

A Dispersal events; B In situ diversification events. A Mean counts of dispersal events aggregated over evolutionary time (123.6 My–0 My) as detected from 1000 Biogeographic Stochastic Mapping (BSM) simulations using DEC + J model. Upper bar plots represent the mean counts of arrivals to a bioregion acting as a destination. Lower bar plots represent the mean counts of departures from a bioregion acting as a source. B Mean counts of in situ cladogenetic events within bioregions aggregated over evolutionary time (123.6 My–0 My) as detected from 1000 BSM simulations using the DEC + J model. Error bars on both plots are standard deviation recorded across the 1000 BSM simulations. Results for alternative divergence dating hypotheses are shown in Supplementary Fig. S13.
