Abstract: | Background The forests of the upper Amazon basin harbour some of the world's highest anuran species richness, but to date we have only
the sparsest understanding of the distribution of genetic diversity within and among species in this region. To quantify region-wide
genealogical patterns and to test for the presence of deep intraspecific divergences that have been documented in some other
neotropical anurans, we developed a molecular phylogeny of the wide-spread terrestrial leaflitter frog Eleutherodactylus ockendeni (Leptodactylidae) from 13 localities throughout its range in Ecuador using data from two mitochondrial genes (16S and cyt
b; 1246 base pairs). We examined the relation between divergence of mtDNA and the nuclear genome, as sampled by five species-specific
microsatellite loci, to evaluate indirectly whether lineages are reproductively isolated where they co-occur. Our extensive
phylogeographic survey thus assesses the spatial distribution of E. ockendeni genetic diversity across eastern Ecuador. |
