Diversity indices and number of haplotypes from historical and modern Iberian wolves based on sequence of the 5′ end of the control region (CR) or the whole mitochondrial genome except the control region (MT). n, number of sequences; H, number of haplotypes; S, number of polymorphic sites; π, nucleotide diversity; Hd, haplotype diversity; ΘS, theta calculated from the observed number of segregating sites; Θπ, theta calculated from the mean number of pairwise differences of nucleotide diversity; ΘK, theta calculated from the observed number of haplotypes; bp, base pairs. Standard deviations are shown in parentheses, 95% confidence intervals in brackets.
