FIGURE 2.Phylogenetic relationships of Scapteromys. A)ML tree of Scapteromys sp. n. haplotypes and relationships within Scapteromys reconstructed using 801 base pairs of cyt-b sequences and rooted with Kunsia tomentosus. Numbers above branches represented bootstrap support (asterisk indicates values <50%) and below indicate genetic divergence based on K2P distances B) Median joining network of the 11 cyt-b haplotypes of Scapteromys sp. n. Areas are proportional to haplotype frequencies. Colors indicate major clades identified from the phylogenetic tree. Small black bars represent nucleotide differences between haplotypes. Small red circles represent missing haplotypes.
