Results from STRUCTURE analyses.

<p>(A) Population structuring among the six localities following the optimal solution of ΔK = 3 using 11 microsatellite loci. (B) Population structuring among mainland Ohio and Pennsylvania localities revealed the optimal number of clusters to be ΔK = 3 across 9 loci. (C) Population structuring among only mainland Ohio localities revealed the optimal number of genetic clusters to be ΔK = 2.
