N_ms = sample size in microsatellite analyses; N_mt = sample size in mtDNA analyses.
Estimates based on microsatellites are given below diagonal and mtDNA variation above diagonal. Results are shown for the initial four-region division, and for the updated five-region scheme in which Haukivesi is split into the Kolovesi and Main Haukivesi areas (in italics). Differentiation in all comparisons was statistically significant at P < 0.001 after a sequential Bonferroni correction, except for **P < 0.01.
