Estimations of demographic expansion parameters (Tajima’s D, Fu’s F_S, mutational time since the expansion [τ] and initial [θ₀] and final [θ₁] theta) for each genetic group.

	Northern group (n = 101)	Central group (n = 195)	Southern group (n = 284)
D a	−0.04 (p = 0.46)	1.02 (p = 0.87)	−0.08 (p = 0.19)
F S a	−0.19 (p = 0.51)	1.75 (p = 0.78)	−3.40 (p = 0.13)
τ	3.28 (1.25–6.86)	2.04 (0.75–3.31)	1.00 (0.87–1.39)
θ 0 b	0.00 (0.00–0.021)	0.00 (0.00–1.647)	0.00 (0.00–0.27)
θ 1 b	2.47 (1.90–20.59)	20.57 (3.40–271.82)	3407.18 (2.32–875.95)

^aEstimations performed grouping all individuals of the whole range or of each genetic group as a single population.

^bThe confidence interval (5–95%) are given in parentheses.
