Fig. 1: Geographic distribution of 31 study cells (23 km2) across the Upper Wabash River Basin (UWB) where eastern chipmunks were sampled from 2001–2003.

All 31 study cells were included in the study-cell level of genetic diversity, whereas the subset of 12 study cells (dotted lines) were used in the patch-level analyses. The subset of 12 had at least four sampled patches with ≥5 individuals chipmunks per patch.
