Summary data for the species groups of the Drosophila subgenus.
Figure 1.
Summarized chronogram for the subgenus Drosophila obtained with BEAST using 218 species and 9 calibration points.
Numbers on nodes indicate ages for the corresponding nodes; asterisks on branches indicate BPP ≥ 90% and numbers are bootstrap support values. Bars represent the 95% highest posterior density (HPD) interval for the divergence times.
Figure 2.
Summarized chronogram for the subgenus Drosophila obtained with BEAST using 153 species and 9 calibration points.
Numbers on nodes indicate ages for the corresponding nodes; numbers on branches indicate BPP values. Bars represent the 95% highest posterior density (HPD) interval for the divergence times.
Figure 3.
Summarized chronogram for the subgenus Drosophila obtained with BEAST using 218 species and 5 calibration points.
Numbers on nodes indicate ages for the corresponding nodes; numbers on branches indicate BPP values. Bars represent the 95% highest posterior density (HPD) interval for the divergence times.
Figure 4.
Ancestral reconstruction of geographic distribution and ecological niche.
Trees showing the main dispersal events (A) and ecological shifts (B) inferred to have occurred during the evolution of the Drosophila subgenus. Clades involved are collapsed and the shift indicated with symbols above the branch.

Table 4.
Results of fitting diversification models to the Drosophila subgenus (A), the tripunctata and closely related species groups (B), and the repleta and closely related species groups (C).
Figure 5.
Backbone topologies used in the MEDUSA analyses.
A) phylogeny backbone from analysis with 218 species and 9 calibration points; B) phylogeny backbone from analysis with 218 species and 5 calibration points. Tip names refer to the species groups (those polyphyletic were clustered into a single clade) and numbers in brackets refer to the species richness of the tip. Numbers on nodes indicate divergence times.
