  1. Variation in body mass (BM, g), head width (HW, mm) and basal metabolic rate (BMR, ml O2 min-1) is presented for bank voles from "all populations" and from Sotkamo "Sympatric population" where mitotypes coexist. Significance of the effects: type of the mtDNA (rutilus vs. glareolus), latitude (lat.) and longitude (insignificant and excluded from table) of population (6 populations) were tested in ANOVA or ANCOVA (for BMR with BM as covariate) models on log transformed traits as dependent variables. Marginal means (and their SDs) for mtDNA types for ANCOVA models were calculated accounting for variation in BM. The insignificant effects (p > 0.1) were hierarchically reduced from the analyses of variances "-" and are not presented in the table. Latitude×longitude interactions affected only males log transformed and residual values of HW (p < 0.045), not included in the table.
