Figure 2From: Complex phylogeographic history of central African forest elephants and its implications for taxonomyMedian-joining networks for African elephants HVR1 mtDNA haplotypes. Circle size is proportional to the haplotype frequency. The numbers on the connecting line determine the number of substitutions estimated by NETWORK V.4. 1. 1. 1. The entire list of haplotypes for HVR1 MJN can be found in Table 1.Back to article page
