Estimates of effective population size (Ne) for five populations calculated with 1118 RAD-derived SNPs that were placed on the linkage map and 39 of the 43 SNPs that were in linkage equilibrium from Templin et al. (2011). Estimates with RAD SNPs are calculated using only comparisons between loci on different linkage groups (Ne linkage removed) and all comparisons (Ne all data). The ratio of effective population size to census size (Ne/N) and effective population size to census size multiplied by generation length (Ne/NG) for each population is also reported (G is generation length and N is an approximate value of yearly escapement for each population, see methods). The Ne used for these calculations is Ne linkage removed (column 2). We did not calculate Ne/N or Ne/NG for the Bristol Bay and upper Yukon populations because confidence intervals included infinity, suggesting our point estimates may not be completely representative.
