    Genetic diversity and phylogeny of Dryomys nitedula and Dryomys laniger from Turkey was described in the present study by using mitochondrial DNA NADH dehydrogenase 1 gene (ND1). Genetic variation in ND1 gene was determined by two model-based phylogenetic analyses and a network analysis revealed 27 haplotypes of D. nitedula constructing four main lineages (Thrace, Anatolia, North-eastern Anatolia and Savsat) that have non-overlapping geographic distributions and no shared haplotypes, but on the other hand, three haplotypes were detected in four samples of D. laniger from Turkey. It was determined that nucleotide diversity was low but haplotype diversity was high in D. laniger, whereas, D. nitedula has both high level of haplotype and nucleotide diversity. Characterization of Thrace lineage of D. nitedula with low nucleotide diversity and determination of the total nucleotide diversity of Anatolian lineages (Anatolia + North-eastern Anatolia + Savsat) to be approximately four times higher than that of Thrace lineage indicated that Anatolia may have served as a refuge for D. nitedula. Divergence times and high level of nucleotide differences between D. nitedula lineages showed that diversification of the lineages may have occurred before and during ice ages in Turkey, thought to be a refuge for post-glacial colonization and biodiversity resource of Europe. Additionally, estimated divergence times and calculated genetic distances yielded compatible results with the previous paleontological and genomic data for the diversification time of two species in the genus.
