Geographic distribution and unrooted statistical parsimony networks for D. monticola haplotypes. The large majority of the geographic distribution contains only a few haplotypes (K, L, M, N, O, & P). The Ozark haplotype (F, red) occurs in the southern Appalachians of northern Georgia amongst a great diversity of related haplotypes. Labels on the network indicate the haplotype and the number of counties where it was found (sizes of circles are also drawn proportional to this number). Colors of haplotypes correspond to pie diagrams on the map and show the frequency of haplotyope in each county sampled. Black dots on haplotype network indicate hypothetical unsampled haplotypes.
