Figure 3 in COI barcoding provides reliable species identification and pinpoints cryptic diversity in Western Palearctic amphibians

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.
