Mismatch distributions of Pardosa astrigera from the whole sample based on the COI sequences (a) and based on the 16S sequences (b) and the NADH1 sequences (c) independently. Bayesian skyline plots from the whole sample (d); middle lines represent median estimates of the effective population size, and shaded areas represent 95% of the highest posterior densities (95% HPD). The effective population size is presented on a logarithmic scale. The LGM represents the last glacial maximum.
