Fig. 2: Global migration network of the DCCs.

a, Phylogeographic trees for DCCs 1–3. Each branch is coloured by continent. b, Intercontinental migration rates for each DCC for the complete dataset and five random subsamples (Methods, number of samples from the posterior distribution: DCC1 complete dataset of 3,157, all DCC1 subsampled datasets, DCC2 subsampled datasets 1, 3 and 5, all DCC3 subsampled datasets of 2,703 each; DCC2 complete dataset, DCC2 subsampled datasets 2 and 4, DCC3 complete dataset of 2,256 each). Boxplot centre lines show median value; upper and lower bounds show the 25th and 75th quantile, respectively; upper and lower whiskers show the largest and smallest values within 1.5 times the interquartile range above the 75th percentile and below the 25th percentile, respectively; and points show samples outside the whisker range. The median and 95% HPD of the complete DCC datasets are shown above the bars of the corresponding DCC. An intercontinental migration rate of 0.02 migrations per lineage per year corresponds to one in 50 lineages moving continent in a year. c, Intercontinental migration pathways for each DCC. Arrows show the direction of supported migration from source continent to recipient continent. Arrows are coloured by originating continent.
