Fig 4

The ML tree based on the mtGenome comprised 14,740 bp (tRNAs = 1,488 bp, rRNAs = 2,532 bp, and protein-coding genes = 10,720 bp). This tree was estimated using the GTR+Γ+I model. Numbered boxes denote nodes. The nodal number indicates the BP value. BP was estimated on the basis of 1,000 bootstrap replicates. The evolutionary constraints on nucleotide substitutions must differ between the first, second, and third codon positions as well as between tRNA and rRNA. Therefore, we specified partitions for each region. Data for the E. lutris and L. lutra (South Korea) were reported previously NC_009692 and FJ236015, respectively.
