Figure 3. A in Historical demography and spatial genetic structure of the subterranean rodent Ctenomys magellanicus in Tierra del Fuego (Argentina)

Figure 3. A, minimum spanning tree of nine mtDNA haplotypes of Ctenomys magellanicus from Tierra del Fuego, Argentina. Areas are proportional to haplotype frequencies, shading indicates populations, and cross hatches represent nucleotide differences between haplotypes. Haplotype numbers correspond to those of Table 1. Abbreviations for populations are given in Figure 1. B, observed and expected mismatch distributions for C. magellanicus (south + north). Dashed line, observed distribution; solid line, theoretical expected distribution under a population expansion model.
