Fig 4. Median-joining network of relationships among dugong mtDNA haplotypes with known location (355bp fragment).

Size of coloured pies represent relative frequency. Lengths of joining lines indicate number of base changes. Colours represent regions of origin. “Restricted”, “widespread” and “eastern” lineages previously reported in Blair et al. 2014. The “eastern” lineage refers to the unnamed outgroup lineage of haplotypes in Blair et al. 2014, found in dugong from other parts of the western Pacific beyond Australia. “Sri Lankan”, “WIO” and “Madagascar” lineages first reported here. Small dots represent unsampled median haplotypes.
