FIG. 6. A majority-rule consensus gene tree reconstructed from mtDNA cytochrome oxidase 1 in Redescription and Recognition of Etheostoma cyanorum from Blue River, Oklahoma
FIG. 6. A majority-rule consensus gene tree reconstructed from mtDNA cytochrome oxidase 1 (CO1) sequence data obtained from the Barcode of Life Database (BOLD). Maximum-likelihood (ML) and Bayesian trees had identical topologies. Branch lengths are proportional to inferred mutations. Shading of lineages represents samples from E. whipplei (outgroup) in black, E. cyanorum in gray, and E. radiosum in white. ML bootstrap proportions/ Bayesian posterior probabilities are reported. See Data Accessibility for tree file.
FIG. 5. A in Redescription and Recognition of Etheostoma cyanorum from Blue River, Oklahoma
FIG. 5. A median-joining haplotype network depicting nucleotide sequence variation in the mtDNA control region (CR). Circles represent unique CR haplotypes and hash marks represent the number of nucleotide differences separating distinct haplotypes. Shaded polygons represent haplotypes grouped by drainage. Haplotypes of E. cyanorum are found only in the Blue River drainage. All haplotypes observed in the Caddo and Little Missouri rivers (not shown in figure) were also observed in the Ouachita River (shown in figure). Etheostoma whipplei is the outgroup taxon (GenBank accession no. U77029).
