The divergence island IDs are in the format ‘chromosome number-DI number’. Asterisks denote DIs identified under the weak criteria; the remaining DIs are identified under the strong criteria. Bold font denotes regions identified in Refs 15 and 22 by the stringent criteria; non-bold font denotes regions identified in Refs 15 and 22 by less stringent criteria, and reported in supplementary materials for these refs. ns, number of nonsynonymous substitutions, s _E, selection coefficient in favor of freshwater allele estimated from Lake Ershovskoye; s _G, selection coefficient in favor of freshwater allele estimated from Quarry Goluboy.
