Fig. 2.—. Phylogenetic analysis of mitochondrial DNA sequences suggest that the “golden” strain used by Olmstead et al. (2010) and samples used in this study (8 for RAD tag analysis and 27 others for PCR assays) originate from Nigeria. Nodes with ≥95% posterior probability are indicated with a black circle. Species names, including those undescribed, follow Evans et al. (2004). Abbreviated country names include the Republic of the Congo (R. Congo), the Democratic Republic of the Congo (DRC), and Equatorial Guinea (EG). The scale bar refers to the number of substitutions per site, gray areas on the map indicate the distribution of tropical forest in West Africa, and the dotted line indicates the approximate distribution of Silurana tropicalis inferred by Tinsley et al. (1996).
