Mitochondrial phylogeography and subspecies of the wide-ranging sub-Saharan leopard tortoise Stigmochelys pardalis (Testudines: Testudinidae) - a case study for the pitfalls of pseudogenes and GenBank sequences

Popis výsledku v původním jazyce

The leopard tortoise (Stigmochelys pardalis) is the most widely distributed sub-Saharan tortoise species, with a range extending from the Horn of Africa all over eastern Africa to the Republic of South Africa, Namibia and southernmost Angola. Using 1938bp of mitochondrial DNA (cyt b gene, partial ND4 gene plus adjacent tRNA genes) from a nearly range-wide sampling, we examined its phylogeographic structure and compared our findings with previously published GenBank sequences. We identified seven majorclades that are largely parapatrically distributed. A few records of distinct haplotypes at the same locality or in close proximity could be the result of translocation of tortoises by man. The greatest diversity occurs in the south of the species' range, with five out of the seven clades. Testing for isolation-by-distance suggests that the observed phylogeographic structure is the result of restricted geographical gene flow and not of historical vicariance. This is in sharp contrast to
