Voles and lemmings (subfamily Arvicolinae) remain some of the most difficult groups for disentangling phylogenetic relations owing to recent very fast explosive radiation. The rapid radiation events are challenging analysis produce bushes various shapes that impossible resolve with a straightforward approach using individual loci. Here quaddRAD-seq technique transcriptomes, we tested whether data from nuclear genome consistent trees inferred earlier loci mitogenomes in topology divergence dating. Both transcriptome convincingly place Arvicola as earliest derivative within Arvicolini. This result is agreement fossil record conventional taxonomy. For first time, whole-genome sequencing resolved third wave subfamily’s taxa, namely tribes Arvicolini, Lagurini, Ellobiusini, which have formed polytomy mitochondrial articles. study indicates dating highly dependent on number position calibration points tree taxa sampling. In terms inference, nodes insufficient representation susceptible errors.

Abstract The subgenus Aschizomys belongs to the genus Alticola (Central Asian mountain vole) and consists of two species: macrotis lemminus. Phylogenetic relationships within remain obscure due limited sampling, an insufficient number molecular markers used in phylogenetic studies, paraphyly observed on mitochondrial trees. In this work, infer reliable evaluate putative scenarios ancient hybridization subgenus, we applied double‐digest restriction site‐associated DNA paired‐end (quaddRAD) sequencing 20 samples (20 individuals), including five species , dated divergence cytochrome b ( cytb ) lineages using a “second calibration” approach. We showed monophyly basis thousands nuclear loci demonstrated traces introgression also genome. Observed could be explained by event rather than incomplete lineage sorting. This explanation was confirmed analysis time. Overall, our results support hypothesis extensive migration during Late Pleistocene, with leading population introgression. expect article become starting point for series rigorous studies history as whole.
