Amphibian phylogeography in the Antipodes: Refugia and postglacial colonization explain mitochondrial haplotype distribution in the Patagonian frog Eupsophus calcaratus (Cycloramphidae)

► Pleistocene climatic changes influenced the genetic patterns of Eupsophus calcaratus. ► Phylogenetic analyses and boundaries of the LGM suggest small refugia within ice fields. ► Genetic divergence of southern populations suggests expansion after glacial retreat.
