Figure 5. Species Distribution Models during current climate scenario (left) and wetter Last Interglacial (right; LIG).

Current sampling points used in model construction are shown. The limited distribution of R. udzungwensis is entirely contained within the suitable area for R. c. reichardi at both time points. During the LIG, the ranges for both species were predicted to occur at lower elevations in the eastern areas of the Udzungwa Mountains foothills. During this time, R. udzungwensis shifted its entire distribution eastward resulting in a loss occupancy in the western Ndundulu/Luhomero forest, a reduced range in the Mwanihana forest, and a relatively extensive distribution east of Mwanihana in the Kilombero Valley including the Magombera forest (see Fig. 1 for place names).
