Figure 4 in COI barcoding provides reliable species identification and pinpoints cryptic diversity in Western Palearctic amphibians

Figure 4. Representation of the barcoding gap for the Anura (upper panel) and Caudata (bottom panel) datasets. Each individual in the dataset is represented by a vertical line in: blue, when a barcoding gap exists (the bottom of the line representing the maximum intraspecific distance, and the top of the line representing the minimum interspecific distance);

Figure 3. Gene tree constructed using the DNA barcode fragment of the COI mitochondrial gene tree for Western Palearctic urodeles, estimated under a Bayesian framework. Nodes are collapsed at the genus level and colours correspond to genera; images are a representative species for each genus. Black dots on nodes indicate posterior probabilities> 0.90.
