Figure 2 in Taxonomy, biogeography and evolution of Euproctus (Amphibia: Salamandridae), with the resurrection of the genus Calotriton and the description of a new endemic species from the Iberian Peninsula

Figure 2. Maximum likelihood (ML) tree for some representatives of the Salamandridae (log likelihood −6882.66489, GTR + I + G model of sequence evolution) inferred from the combined dataset, which included cytb, 12S and 16S mtDNA sequences. Bootstrap support and Bayesian posterior probabilities for particular nodes are shown in the boxes with the figures indicating the percentage support for different analyses. Upper left, bootstrap support derived by ML (GTR + I + G). Upper right, posterior probability values from the Bayesian analysis (GTR + I + G). Lower left, maximum parsimony (MP) bootstrap support derived by MP (ts = 1; tv = 1). Lower right, bootstrap support derived by MP (ts = 1; tv = 4 and cytb 3rd codon ts = 0). When the difference between the four support values was <5%, only the average value is shown. The '<' symbol is used to show that the bootstrap/posterior probability value for that node is lower than 50% and the '–' symbol indicates that a particular node is never recovered when using this method. Estimated ages are given for some bifurcations, which are marked by filled circles. Numbers in square brackets refer to localities shown in Fig. 1 and listed in Table 1.
