To examine phylogenetic relationships within the Asian lineage of voles (Microtus) belonging to subgenus Alexandromys, mitochondrial cytochrome b gene (cytb) was sequenced for its representatives, and results were compared with cytogenetic, morphological, paleontological data. In all trees inferred from maximum likelihood, parsimony, Bayesian analyses, clade is subdivided into highly supported Alexandromys s.s. moderately Pallasiinus lineages. Four subclades are recovered Alexandromys: (1)...

Arvicolinae is one of the most impressive placental radiations with over 150 extant and numerous extinct species that emerged since Miocene in Northern Hemisphere. The phylogeny has been studied intensively for several decades using morphological genetic methods. Here, we sequenced 30 new mitochondrial genomes to better understand evolutionary relationships among major tribes genera within subfamily. phylogenetic molecular dating analyses based on 11,391 bp concatenated alignment...

A species-wide phylogeographic study of the narrow-headed vole Lasiopodomys (Stenocranius) gregalis was performed using mitochondrial (mt) cytochrome b gene. We examined 164 specimens from 50 localities throughout species distribution range. Phylogeographic pattern clearly demonstrates division into four major mtDNA lineages with further subdivision. The level genetic differentiation between them found to be extremely high even for level: about 6–11%. most striking result our is mutation...

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...

Central Asian mountain voles Alticola is one of the least known groups both in evolution and life history. This genus includes three subgenera s.str. , Aschizomys Platycranius belongs to tribe Clethrionomyini comprising also red‐backed Clethrionomys oriental Eothenomys . In order elucidate phylogenetic relationships within examine its position tribe, mitochondrial cytochrome b (cyt ) gene variation was estimated, results were compared with morphological palaeontological data. Maximum...

Phylogenetic relationships, taxonomy and nomenclature issues within East Asian voles Alexandromys were addressed using comprehensive species samples, including all 12 valid of the genus, multilocus analysis. We examined mitochondrial cytochrome b ( cytb ) gene three nuclear genes in 36 specimens. Additionally, we a data set 106 specimens only gene. Our results did not confirm aggregation A. kikuchii , montebelli oeconomus into separate clade, namely subgenus Pallasiinus . Analysis incomplete...

Recent study on Lasiopodomys ( Stenocranius ) gregalis has revealed four clear mitochondrial lineages with differences exceeding the species level. The most divergent is clade from south‐eastern Transbaikalia. Multilocus (six nuclear genes), morphological (dental characters of m1 and M3) behavioural (breeding experiments) analyses were conducted to test hypothesis that L. a complex two cryptic species. All applied methods distinguish independent status voles This occupies portion...

Life under the earth surface is highly challenging and associated with a number of morphological, physiological behavioral modifications. Subterranean niche protects animals from predators, fluctuations in environmental parameters, but characterized by high levels carbon dioxide low oxygen implies energy requirements burrowing. Moreover, it lacks most sensory inputs available above ground. The current study describes results RNA-seq analysis four subterranean voles subfamily Arvicolinae:...

Abstract Background Mitochondrial genes encode proteins involved in oxidative phosphorylation. Variations lifestyle and ecological niche can be directly reflected metabolic performance. Subterranean rodents represent a good model for testing hypotheses on adaptive evolution driven by important shifts. Voles lemmings of the subfamily Arvicolinae (Rodentia: Cricetidae) provide example studies radiation. This is youngest group within order Rodentia showing fastest rates diversification,...

The extraction of museum DNA from a unique collection samples the “Crocidura pergrisea” species complex, which comprises local endemics Central and West Asia, allowed us to determine their inter- intragroup relationships. first step this study was re-evaluation heavily damaged type specimens C. armenica via microcomputed-tomography-based cybertaxonomic approach (CTtax), enabled precise description species’ morphology; three-dimensional models cybertypes were made available through MorphoBank...

This study evaluates signatures of selection in the evolution mitochondrial DNA voles, subfamily Arvicolinae, during colonization subterranean environments. The comparative sequence analysis protein-coding genes eight vole species (Prometheomys schaposchnikowi, three genus Ellobius: Ellobius talpinus, fuscocapillus and lutescens, two Terricola: Terricola subterraneus daghestanicus, Lasiopodomys mandarinus, Hyperacrius fertilis) their closest aboveground relatives was applied using...

Morphometric variation of voles Microtus middendorffii sensu lato and M. gromovi was examined based on 221 skulls.Molecular assessed partial sequences cytochrome C oxidase subunit I gene (657 bp) from 23 individuals s.l.The observed pattern within s.l.corresponds to polytypic species comprising a number geographic races.The taxonomic rank the Ural Yamal race (M.m. ryphaeus) is not lower than m. hyperboreus.Essential morphological differences scope this study were found for sample Kochechum...

The endemic Norwegian lemming (Lemmus lemmus) is an icon for cyclic species, famous since the Middle Ages its enormous population outbreaks and mass movements. Although drivers behind this cyclicity have been intensively investigated, virtually nothing known about extent to which long-distance dispersal during peaks actually lead gene flow among mountain tundra areas. In article, we use nine microsatellite markers address question analyse range-wide genetic diversity differentiation between...

In this article, we present the nearly complete mitochondrial genome of Subalpine Kashmir vole Hyperacrius fertilis (Arvicolinae, Cricetidae, Rodentia), assembled using data from Illumina next-generation sequencing (NGS) DNA a century-old museum specimen. De novo assembly consisted 16,341 bp and included all mitogenome protein-coding genes as well 12S 16S RNAs, tRNAs D-loop. Using alignment 14 previously published Arvicolini tribe mitogenomes, seven Clethrionomyini also Ondatra Dicrostonyx...

The subterranean voles of the genus Ellobius are species subfamily Arvicolinae well adapted to underground life. In this paper, we report assemblies complete mitochondrial genomes for three mole from – northern vole talpinus (16,376 bp), transcaucasian E. lutescens (16,540 and southern fuscocapillus (16,388 bp).
