dc.description.abstractPartial sequences of three mitochondrial DNA genes, 12S rDNA, 16S rDNA and cytochrome b, and one nuclear gene, c-mos, were used to assess the phylogenetic relationships of species belonging to the genus Afroablepharus from the volcanic islands of the Gulf of Guinea (West Africa) and neighboring continental Africa. Additionally, partial sequences of cytochrome b were used to compare levels of sequence divergence within populations. The three forms from São Tomé, Príncipe and Annobon (one per island) are genetically distinct, with high levels of divergence, supporting the recognition of a distinct species in each island. Populations within each island contain very low levels of genetic diversity. These three forms form a monophyletic group suggesting a single initial colonization followed by radiation to the other islands, possibly from São Tomé to Príncipe and Annobon. This is contrary to what was found in other reptiles from these islands such as Mabuya (sensu lato) and Hemidactylus, which colonized the islands multiple times. Assuming a molecular clock for cytochrome b of about 2% divergence per million years (usually applied to Sauria), the lineage on Annobon island exceeds the age of the island, thus casting further doubt on this widely used divergence estimate. Partial sequences of c-mos showed no variation within islands. Five to seven sites were variable among islands, which is a high value further supporting the treatment of each island form as a distinct species.pt_PT
