The distributions of nrDNA genotype and Network relationships.

<p><b>(a)</b> Geographical distribution of nrDNA haplotypes (H1–H34) detected in <i>U</i>. <i>rockii</i> and <i>U</i>. <i>henryi</i> (population codes see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0186378#pone.0186378.t001" target="_blank">Table 1</a>). <b>(b)</b> Median-joining network of nrDNA haplotypes (H1–H34). Sizes of the circles in the network are proportional to the observed frequencies of the haplotypes. The small black bars represent mutation steps and the black dots (MV) represent missing haplotypes.
