Figure 2. Geographic distribution and haplotype networks for 12S in Effects of Quaternary climatic oscillations over the Chacoan fauna: phylogeographic patterns in the southern three-banded armadillo Tolypeutes matacus (Cingulata: Chlamyphoridae)

Figure 2. Geographic distribution and haplotype networks for 12S (top panels) and control region (bottom panels). The panels on the left plot the geographical distribution and frequency of haplotypes in the different localities analysed. Localities were labelled according to their ID (see Table 1). The right panels show the haplotype networks, where the dashes on the lines represent mutations, and the black circles represent intermediate variants not found. Principal Chacoan rivers are shown in light-blue labels. Capitalized labels indicate names of Argentinean provinces, and labels with all letters in uppercase refer to neighbouring countries.
