  1. Contemporary population effective size was estimated using the Linkage Disequilibrium method (Ne˄ LD); 95% confidence interval (CI) of Ne based on Jackknifing over loci is reported within brackets. Recent population bottlenecks were assessed testing for the probability of heterozygosity excess related to the heterozygosity expected at mutation-drift equilibrium (HE > HEQ). Equilibrium heterozygosity was estimated by a Two-Phase Mutation Model with increasing proportion of single-step mutations: 70% (PTPM70), 80% (PTPM80) and 90% (PTPM90). Populations are abbreviated as in Table 1.
