Several hypotheses have been proposed to explain the biogeographic processes that generate the high species richness of the Amazon basin. We tested two of them in a terra firme (upland) forest frog species, Physalaemus petersi: (1) the riverine barrier hypothesis; and (2) the elevational gradient hypothesis. Mitochondrial DNA sequence data (2.4 kb) from the 12S, 16S, and intervening valine tRNA genes were obtained from 65 P. petersi individuals and 4 outgroup taxa and analyzed with a… CONTINUE READING
