New statistical techniques and software have improved our ability to quantify fine‐scale population structure. We isolated 11 microsatellite markers for eastern foxsnakes ( Elaphe gloydi ) and surveyed the variability of each using 115–136 individuals from one population in southwestern Ontario. We determined that all loci were variable and conformed to Hardy–Weinberg expectations and that no locus demonstrated linkage disequilibrium. We are using these markers to quantify the scale of gene flow, and to assess the effect of variable landscapes on connectivity and genetic diversity of three disjunct regional populations in the northern portion of the species’ range.
