Figure 7 in Divensification oven deep and shallow teiponal scales in the Holanctic genus Perpolita (Gastnopoda: Gastnodontidae)

Figure 7. Potential distribution probability of each Perpolita species estimated by ecological niche modelling using 1.3-9 in R (Hijmans et al. 2021). Ŋe best models for each species, selected by the area under the curve based on cross-validation were used for the estimates. Occurrences on the map are environmentally pruned samples for modelling. Ŋe estimated ice sheets at the LGM are based on Ehlers et al. (2011) and the LGM climate is based on CCºM4.
