Fig. 5: Ecological niche models for the combined northern and southern populations of Neotoma fuscipes in California.

A Combined north present day; B combined north last glacial maximum; C south present day; D south last glacial maximum. Note the reduction of possible suitable areas in the past for both the northern and southern populations. Blue lines in A and C indicate rivers >50 m (made with Natural Earth. Free vector and raster map data @ naturalearthdata.com), and blue pixels in B and D indicate ice or paleolakes during the last glacial maximum (Dyke et al. 2003). The blue triangle in B and D indicate the origin of expansion for the combined north and south, respectively.
