Maximum Likelihood phylogram depicting relationships within the Rhinella margaritifera species group. The phylogram was derived from the analysis of 3045 bp of mitochondrial (12S, 16S, COI) and nuclear (Tyr) genes. Numeric codes on terminals are individual collection numbers (associated data listed in Table 1). Posterior probabilities (above) and bootstrap values (below) are shown on branches except when they are < 0.50 and 50%, respectively. Abbreviations are: EC = Ecuador, FG = French Guyana, BR = Brazil, BO = Bolivia, PE = Peru, PA = Panama. Outgroups are not shown.
