Figure 2. A in Integrative revision of the Lygodactylus gutturalis (Bocage, 1873) complex unveils extensive cryptic diversity and traces its evolutionary history

Figure 2. A, Multilocus species tree and Bayesian chronogram of divergences among Afro-American Lygodactylus clade (Clade C of Gippner et al. 2021), based on an alignment of 13 concatenated markers (including eight nuclear-encoded genes, four protein-coding mitochondrial genes, and the 16S mitochondrial rRNA gene, see Gippner et al. 2021). Branches with posterior probability> 0.9 are denoted by asterisks (*) at relevant nodes. Blue bars depict 95% High Probability Density (HPD) intervals of estimated divergence dates. B, Median-joining nuclear allele network showing the relationships between the L. picturatus-fischeri groups, inferred from the RAG1 nuclear gene (262 bp including all available RAG1 sequences of the L. picturatus-fischeri groups). C, Median-joining nuclear allele network of the RAG1 nuclear gene (980 bp) showing the relationships within the L. gutturalis subgroup, excluding L. gutturalis s.s. In all networks, circle frequency of alleles and small lines represent mutational steps.
