FIGURE 139 in The arctic and alpine bumblebees of the subgenus Alpinobombus revised from integrative assessment of species' gene coalescents and morphology (Hymenoptera, Apidae, Bombus)

FIGURE 139. Most likely biogeographic reconstruction for species of the subgenus Alpinobombus from S-DIVA analysis using the short-distance dispersal (no jumps) model in Fig. 8 and the estimate of phylogeny in Fig. 138 with B. ignitus as the outgroup (not shown). Letters represent the areas listed in Table 6 and in Fig. 8: letter combinations in grey below terminals show species' current distributions; letter combinations above the nodes show the (joint) most likely optimised reconstructions of ancestral distributions, with the probabilities of these solutions for these nodes shown below the nodes (selected alternative reconstructions with lower probabilities are shown in parenthesis and the solutions with more widespread and undifferentiated distributions are shown in grey). Numbers in circles at nodes identify events discussed in the text.
