Gene haplotype networks. Each network corresponds to a single gene: COI (A), CYB (B) and N13 (C). Different textures represent the studied populations, and each coloured circle represents a haplotype found in the sample. Black dots represent intermediate (non-present) haplotypes, lines connecting haplotypes (either existing or not) represent one nucleotide change, the size of each circle is proportional to the haplotype frequency in the sample and the colours of the circles correspond to the three groups: W (red), C (blue) and S (green).
