Figure 3. Median-joining network depicting all haplotypes found for the Aylacostoma specimens from the High Paraná River included in the ex situ conservation programme. The size of circles is proportional to haplotype frequency. Mutational steps separating haplotypes are indicated. For localities, see Table 1.
