FIGURE 2.

Population differentiation, effective population size, and observed heterozygosity for walleye (Sander vitreus) in three North American waterbodies. Cedar Bluff Reservoir (Kansas, USA) represents an entirely stocked population of walleye, while Lake Manitoba and Lake Winnipeg (Manitoba, Canada) walleye represent populations with possible gene flow. F _ST represents Weir & Cockerham's pairwise F _ST, while H_O observed heterozygosity, each found using Hierfstat. Effective population size for each population is represented by N_e, found using NeEstimator v2. For F _ST and N_e, 95% confidence intervals are provided in parentheses
