Ancient DNA of narrow-headed vole reveal common features of the Late Pleistocene population dynamics in cold-adapted small mammals.

The narrow-headed vole, collared lemming and common vole were the most abundant small mammal species across the Eurasian Late Pleistocene steppe-tundra environment. Previous ancient DNA studies of the collared lemming and common vole have revealed dynamic population histories shaped by climatic fluctuations. To investigate the extent to which species with similar adaptations share common evolutionary histories, we generated a dataset comprised the mitochondrial genomes of 139 ancient and 6 modern narrow-headed voles from several sites across Europe and northwestern Asia covering approximately the last 100 thousand years (kyr).

Genetic Diversity of Species of Microtus Generic Group (Arvicolinae, Rodentia): New Data from the Greater Caucasus.

Using the cytochrome b gene (1143 bp), species identification and the phylogenetic analysis of voles of the generic group Microtus from the eastern part of the Greater Caucasus, including the Ismayilli, Khizi, and Balakan Districts of Azerbaijan, have been carried out. Three species, the Major's pine vole (M. majori), the social vole (M.

Phylogenetic Relationships of Burbot (Lota lota L., 1758) of the Volga-Kama River Basin Inferred from the Analysis of Mitochondrial DNA Markers.

The phylogenetic relationships of burbot (Lota lota L., 1758) of the Volga-Kama River basin are reconstructed for the first time. The sequences of the gene cytochrome b and the mtDNA control region obtained for 44 samples from the Kama River and Mezhevaya Utka River (the Volga River tributaries) are studied.
