Allele frequencies for locus L20. Codes correspond to locations in Figure 1, locations belonging to the southern lineage are encircled and extinct populations are shown in bold. The actual values of frequencies are represented by dots of varying diameter: allele codes are indicated on the x axis and population names on the y axis.

Genetic differentiation between pairs of populations. Codes correspond to locations in Figure 1 and are ordered from north to south, bold characters are extinct populations. Genetic differentiations (FST) were estimated with the estimator θ, and are reported above the diagonal while Jost's DEST are reported below the diagonal. All values are significant at P <0.001 after multiple test correction.
