Figure 4 in Recent mitochondrial lineage extinction in the critically endangered Javan rhinoceros

Figure 4. Neighbor-Joining network. The analysis of 14 modern and historical Javan and Indian rhinoceros mitochondrial DNA sequences was conducted using the 'Integer Neighbor-Joining' algorithm implemented in POPART. We used the partial D-loop region of 413 bp to maximize the number of available Javan rhino samples. 'Javan_annamiticus' represents the recently extinct (since 2010) Vietnamese subspecies Rhinoceros sondaicus annamiticus. Each circle represents a certain haplotype; smaller black circles indicate median vectors. Small black lines connecting branches between the haplotypes denote the number of mutation steps separating the haplotypes. Sample identities and regions of origin for the Javan rhinoceros samples are indicated next to each circle. Numbers in the legend indicate the number of sequences in each group.
