Fig. 9 in Can biogeography help bumblebee conservation?

Fig. 9. History of dispersal for the two principal bumblebee groups. Principal outward dispersal corridors for Lowland Grassland (LG, green) and Montane Grassland (MG, blue) bumblebees (groups as in Fig. 6), showing some of the changing barriers as grey rectangles (Williams et al. 2017b; Williams et al. 2022b) (dispersal patterns estimated using DIVALIKE+J in BioGeoBEARS fitted with Bayesian methods). For simplicity, dispersals in the reverse directions are not shown. Background map as in Fig. 1.
