| Title | Refugia within refugia as a key to disentangle the genetic pattern of a highly variable species: The case of Rana temporaria Linnaeus, 1758 (Anura, Ranidae) |
| Abstract | Two distinct lineages of Rana temporaria are known in the Palaearctic region, but it is uncertain whether this species persisted in one or more Pleistocene refugia. We resolved the phylogeographic history and genetic variability of R. temporaria in the Italian peninsula, a 'traditional' Pleistocene refugium, and related our findings to patterns described for other European populations. |

We resolved the phylogeographic history and genetic variability of R. temporaria in the Italian peninsula, a traditional Pleistocene refugium, and related our findings to patterns described for other European populations. We sequenced the mitochondrial markers Cox I and cytochrome b. Phylogenetic reconstruction only indicated the presence of haplotypes belonging to the Western lineage in the Italian peninsula. Overall, the genetic variability of Italian populations was higher than other European populations, which shared haplotypes with the Alpine populations. We demonstrated subdivision into five main Italian sublineages, which was associated with a geographical structure of populations in two divergent groups. In particular, one Apennine group might have resulted from bottlenecks during the last interglacials ages. In contrast, Alpine populations were recently diverged and showed incomplete lineage sorting. 65 Articolo in rivista Academic Press, 1055 7903 Molecular phylogenetics and evolution Print Molecular phylogenetics and evolution Print Mol. phylogenet. evol.
