Evaluating the Utility of Single-Locus DNA Barcoding for the Identification of Ribbon Worms (Phylum Nemertea)
Fig 4
Result from the manual calculations of intraspecific (red) and interspecific (blue) COI distances using species affiliation determined by the ML solution in PTP.
Note the presence of a short barcoding gap at ~3–5%, which is further discussed in the text. A, Nemertea, full view of the chart with the x-axis set above the upper limit of the number of comparisons within the dataset; B, Nemertea, enlarged view of the barcoding gap region with the x-axis set to a maximum of 500 comparisons.
