Pair-wise genetic distance as computed by F_ST among the 6 populations displaying within-river temporal genetic changes. Computed for historical (bottom left) and contemporary samples (top right), and based upon the analysis of 22 loci.

Computed for historical (bottom left) and contemporary samples (top right), and based upon the analysis of 22 loci. All FST values significant at α 0.001 with the exception of those in bold.本结果基于22个基因位点（loci）的分析，分别针对历史样本（左下角）与当代样本（右上角）计算得到。除加粗标注的数值外，所有FST（固定化指数，Fixation Index）值在显著性水平α=0.001下均具有统计学显著性。
