Figure 3 in The limits of mtDNA analysis for determining the provenance of invasive species: a midwife toad example

Figure 3. Median Joining Network of 74 ND4 mtDNA haplotypes of the common midwife toad (Alytes obstetricans). Pie size reflects haplotype frequency and red numbers between parentheses reflect the number of substitutions (if greater than 1). The prefix 'Ao_H' is omitted from haplotype labels. Haplotype details can be found in supplementary table S1.
