Fig. 1 Panel a in Historical biogeography highlights the role of Miocene landscape changes on the diversification of a clade of Amazonian tree frogs

Fig. 1 Panel a, time-calibrated phylogeny of Osteocephalus, Tepuihyla and Dryaderces in Amazonia, resulting from a mitogenomic analysis in BEAST and displaying the mean and 95% CI (blue bars) of divergences. Nodes are numbered in red (age details are in Electronic Supplement 1), and support values are depicted for Bayesian (following node symbol colours) and maximum likelihood analyses (following numbers below the nodes). Topological discrepancies between analyses for four low-supported nodes (21, 25, 34 and 43)
