Fig. 11 in The steppe bumblebees of the subgenus Sibiricobombus revised world-wide from species' gene coalescents and morphology despite numts (Hymenoptera, Apidae, genus Bombus)

Fig. 11. Most likely ancestral ranges reconstructed for all extant currently recognised species of the subgenus Sibiricobombus Vogt, 1911 from the dispersal model in Fig. 10, using the model DIVALIKE+J in S-BioGeoBEARS from a sample of 10 000 trees from BEAST used to make the estimates of species phylogenies from the six genes in Fig. 7. Letters represent the area units in Fig. 10: letter combinations at terminals show species' current distributions (key lower left shows the colour codes used for the principal areas of endemism, other colours not in the key represent combinations of areas e.g., olive for area combination AE); letter combinations at nodes show the most likely reconstructions for ancestral distributions, with pies indicating the percentage of solutions for that node in which solutions occur (with black for a mixture of subsidiary solutions each with p
