Table 4. Descriptions of prior settings and median estimations of posterior distributions of parameters revealed by the diyabc modeling of the best-fitting scenarios for the diversification history of (a) the three regional EST-SSR ( structure ) clusters of D. versipellis s. lat. (west-north, east, south); and (b) the three taxonomic units of its ‘southern cluster’, i.e. D. versipellis (south), D. difformis, and D. majoensis.

See Materials and Methods, Supplementary Fig. S5, and Table S5 for details. In (a), NDP, NDV(WN), NDV(E), and NDV(S1) denote the current population sizes of, respectively, D. pleiantha, D. versipellis west-north cluster, D. versipellis east cluster and D. versipellis south cluster (including D. difformis and D. majoensis). In (b), NDV(S2), NDD, and NDM represent the current population sizes of, respectively, D. versipellis south cluster, D. difformis and D. majoensis. NA represents the population size of the ancestral lineage at the basal node. μ denotes the mutation rate (per generation per locus) for the EST-SSRs. P represents the proportion of multiple step mutations in the generalized stepwise model, GSM.
