FIGURE 1. A in Dendropsophus minutus (Anura: Hylidae) of the Guiana Shield: using DNA barcodes to assess identity and diversity
FIGURE 1. A: Geographic distribution of populations sampled for this study. Inset map indicates region focused on (Guianas) as well as the type locality of D. minutus (red star). Numbers correspond to localities listed in Specimens Examined section. B: Neighbor Joining tree illustrating relationships among major lineages of 'D. minutus' from the Guianas. Colored circles correspond to like colored localities in A. Bootstrap support values above 70% and 99% are indicated by a circle and asterisk respectively. Interrealtionships among A, B & C are poorly resolved and average pariwise sequence divergence (uncorrected) among these lineages does not exceed 1.5%. Average divergence between D and ABC is 9%.
