| Abstract |
|
Phylogeography of Hydromedusa maximiliani was assessed by sequencing a 416 bp fragment from the mtDNA control region. Based on this fragment, 18 haplotypes were detected among individuals from four populations throughout southeastern Brazil. Two major geographical groups could be distinguished, a western population represented by individuals from São Paulo state, and an eastern population, represented by individuals from Rio de Janeiro and Minas Gerais states. Divergence dates of 8-16 million years ago for eastern and western H. maximiliani populations fit orographical activities resulting in Serra do Mar and the Serra da Mantiqueira mountain uplifts during Pliocene and Miocene
