Spatial genetic heterogeneity in SSR data and its association with plastid DNA haplotypes, i.e. cytonuclear disequilibria, and altitude.

The mean sPCA score for the first sPCA axis is given for individuals carrying the same haplotype, sPCA (hap), or belonging to the same ad hoc altitudinal class sPCA (alt); n, sample size range per altitudinal class. P values represent the significance of ANOVA analyses testing differences in the mean sPCA score for haplotypes, P(hap) or altitudinal classes, P(alt). nc1, not computed because coordinates were unavailable or populations were monomorphic; nc2, not computed because SSR and plastid DNA data were collected from different individuals; ns, not significant; ***, P≤0.001; **, P≤0.01; *, P≤0.05.
