Voles and lemmings (subfamily Arvicolinae) remain some of the most difficult groups for disentangling phylogenetic relations owing to recent and very fast explosive radiation. The rapid radiation events are challenging for phylogenetic analysis and produce bushes of various shapes that are impossible to resolve with a straightforward approach using...
The voles and lemmings (subfamily Arvicolinae) remain one of the most difficult groups for disentangling phylogenetic relationships due to recent and very fast explosive radiation. The rapid radiations are challenging for phylogenetic analysis producing bushes of various forms impossible to resolve with a straightforward approach using individual l...
Dormice (family Gliridae) are an ancient group of rodents. It was fully dominant in the Oligocene and Early Miocene, and its current diversity is represented by a few extant species. A Kazakhstani endemic, the desert dormouse Selevinia betpakdalaensis is one of the most enigmatic dormouse species. Lack of genetic data has not allowed Selevinia to b...
In 2023, B. Kryštufek and G.I. Shenbrot published a paper in which they proposed to consider invalid 20 lectotype designations based on the specimens in the collection of mammals at the Zoological Institute of the Russian Academy of Sciences (St Petersburg). They also designated a lectotype for Lemmus obensis bungei Vinogradov, 1926. We argue that...
Dormice (family Gliridae), is an ancient group, in the Oligocene and Early Miocene it was the entirely dominant rodent family, and current diversity is represented with few extant species. The Kazakhstan endemic, desert dormouse Selevinia betpakdalaensis is one of the most enigmatic dormouse species. The lack of genetic data did not allow Selevinia...
The extraction of museum DNA from a unique collection of samples of the “Crocidura pergrisea” species complex, which comprises local endemics of Central and West Asia, allowed us to determine their inter- and intragroup relationships. The first step of this study was the re-evaluation of heavily damaged type specimens of C. armenica via a microcomp...
The subgenus Aschizomys belongs to the genus Alticola (Central Asian mountain vole) and consists of two species: Alticola macrotis and Alticola lemminus. Phylogenetic relationships within the subgenus Aschizomys remain obscure due to limited sampling, an insufficient number of molecular markers used in phylogenetic studies, and paraphyly observed o...
Despite the high level of interest, the population history of arctic foxes during the Late Pleistocene and Holocene remains poorly understood. Here we aimed to fill gaps in the demographic and colonization history of the arctic fox by analyzing new ancient DNA data from fossil specimens aged from 50 to 1 thousand years from the Northern and Polar U...

In this paper, we report the complete mitochondrial genome of the northern smooth-tailed treeshrew Dendrogale murina, which was sequenced for the first time using the Illumina next-generation sequencing (NGS) technology. The total length of the mitochondrial genome is 16,844-16,850 bp and encodes 37 genes, including two ribosomal RNAs (rRNAs) 12S a...
Life under the earth surface is highly challenging and associated with a number of morphological, physiological and behavioral modifications. Subterranean niche protects animals from predators, fluctuations in environmental parameters, but is characterized by high levels of carbon dioxide and low levels of oxygen and implies high energy requirement...
Historical DNA of museum specimens is of paramount importance in elucidation of complex nomenclature issues and a priceless source of material gathered during preceding centuries in hardly accessible today sites. Here we report the results of genotyping type specimens of Lemmus obensis bungei Vinogradov, 1925 from the collection of the Zoological I...
Background
Ancient DNA studies suggest that Late Pleistocene climatic changes had a significant effect on population dynamics in Arctic species. The Eurasian collared lemming ( Dicrostonyx torquatus ) is a keystone species in the Arctic ecosystem. Earlier studies have indicated that past climatic fluctuations were important drivers of past populati...
The narrow-headed vole complex includes two cryptic species, Lasiopodomys raddei and L. gregalis, and three allopatrically-distributed lineages with obscure taxonomic ranks within the latter. Based on the RNA-seq data of 12 specimens, the current study aims to find the molecular mechanisms of intraspecies differentiation and, in particular, reprodu...
This study evaluates signatures of selection in the evolution of the mitochondrial DNA of voles, subfamily Arvicolinae, during the colonization of subterranean environments. The comparative sequence analysis of mitochondrial protein-coding genes of eight subterranean vole species (Prometheomys schaposchnikowi, three species of the genus Ellobius: E...
Arvicolinae is one of the most impressive placental radiations with over 150 extant and numerous extinct species that emerged since the Miocene in the Northern Hemisphere. The phylogeny of Arvicolinae has been studied intensively for several decades using morphological and genetic methods. Here, we sequenced 30 new mitochondrial genomes to better u...

Background
Mitochondrial genes encode proteins involved in oxidative phosphorylation. Variations in lifestyle and ecological niche can be directly reflected in metabolic performance. Subterranean rodents represent a good model for testing hypotheses on adaptive evolution driven by important ecological shifts. Voles and lemmings of the subfamily Arv...

Geographic isolation is among the most important factors initiating speciation in mammals. The narrow-headed vole Lasiopodomys gregalis is a widely distributed species in steppe habitats of South Siberia that are highly fragmented by mountain ranges. There are three major mostly allopatric mitochondrial lineages of L. gregalis described throughout...
In this article, we present the nearly complete mitochondrial genome of the Subalpine Kashmir vole Hyperacrius fertilis (Arvicolinae, Cricetidae, Rodentia), assembled using data from Illumina next-generation sequencing (NGS) of the DNA from a century-old museum specimen. De novo assembly consisted of 16,341 bp and included all mitogenome protein-co...
The subterranean voles of the genus Ellobius are species of subfamily Arvicolinae well adapted to underground life. In this paper, we report the assemblies of complete mitochondrial genomes for three mole voles from genus Ellobius – northern mole vole Ellobius talpinus (16,376 bp), transcaucasian mole vole E. lutescens (16,540 bp), and southern mol...
The range of Arianta arbustorum is spreading eastwards across the Baltic Sea region. Because A. arbustorum is a common pest in agriculture and horticulture, understanding the origin and factors involved in the eastward range expansion of the land snail are important for future planning of species management. In the present study, we compared the ge...
In this paper, we report the complete mitochondrial genome of the common pine vole Microtus (Terricola) subterraneus, which was sequenced for the first time using Illumina next-generation sequencing (NGS) technology. The total length of the mitogenome was 16,398 bp and contained 12S, 16S rRNAs, 22 tRNAs, 13 protein-coding genes, and a 883 bp D-loop...
The genetic diversity of two native Siberian and two invasive European populations of the Asian ladybird Harmonia axyridis was studied under laboratory conditions. Analysis of the population genetic structure revealed a high degree of isolation of the monomorphic population from Sochi, monomorphism of the population from Serbia, and high genetic he...
In this study, we present an assessment of the evolutionary history and phylogenetic relationships of Asian mountain voles of the subgenus Aschizomys, genus Alticola, based on extensive sampling and phylogenetic analyses of data from mitochondrial and nuclear markers. Two species of this subgenus are wide spread in the mountain areas of northeaster...
Two names ( Clethrionomys and Myodes ) are used interchangeably for red-backed voles, which is contrary to one of the fundamental principles of zoological nomenclature, that each taxon has a single and unique valid name. Fixation of Mus lemmus Linnaeus, 1758, as the type of Myodes Pallas, 1811, meets the requirements stipulated in the Article 69.1....
The voles of the subgenus Microtus, which includes six species of the so-called “arvalis” group, have always been problematic for classification. Some group members differ in chromosome number and karyotype structure and yet appear morphologically indistinguishable, while others have very similar karyotypes despite exhibiting significant morphologi...
Phylogenetic relationships, taxonomy and nomenclature issues within East Asian voles Alexandromys were addressed using comprehensive species samples, including all 12 valid species of the genus, and multilocus analysis. We examined the mitochondrial cytochrome b (cytb) gene and three nuclear genes in 36 specimens. Additionally, we examined a data s...
The variation of a fragment of the gene for cytochrome oxidase subunit 1 (COI) of the land snail Arianta arbustorum L. collected in the Leningrad oblast is studied. The population under study demonstrates very poor diversity at both the haplotype and nucleotide levels. The performed tests suggest the bridgehead scenario of the land snail invasion,...
The proper use of species names depends entirely on verifying whether newly analysed specimens are conspecific with the type material. True lemmings (Lemmus) are the most common rodents of the Arctic tundra in the Old and New World and play an important role in the Arctic ecosystem; however, their taxonomy is far from resolved. The Amur lemming (L....
The intraspecific structure of the European anchovy (Engraulis encrasicolus) was studied on the basis of mitochondrial cytochrome b gene (cytb) fragment variability in 84 individuals from seven localities of the Black Sea and the Sea of Azov. The data on haplotype and nucleotide diversity and the values of neutrality tests suggested expansive growt...
Long-standing taxonomic and nomenclature issue of Lemmus obensis chrysogaster Allen, 1903 (Rodentia, Cricetidae) resolved Abstract: The taxonomic status and nomenclature of the golden lemming (Lemmus obensis chrysogaster) remained a puzzle for more than 100 years. It was considered either as an independent species Lemmus chrysogaster or as a subspe...
The endemic Norwegian lemming (Lemmus lemmus) is an icon for cyclic species, famous since the Middle Ages for its enormous population outbreaks and mass movements. Although the drivers behind this cyclicity have been intensively investigated, virtually nothing is known about the extent to which long-distance dispersal during population peaks actual...
Background. One of the most mysterious phenomenon related to biological invasions is the so-called “genetic paradox”. It is supposed that invasive species population starts from a small number of individuals and thus should possess low genetic variation, and then what mechanisms provide it successive distribution instead of lower survivorship in fr...
Recent study on Lasiopodomys (Stenocranius) gregalis has revealed four clear mitochondrial lineages with differences exceeding the species level. The most divergent is the clade from south-eastern Transbaikalia. Multilocus (six nuclear genes), morphological (dental characters of m1 and M3) and behavioural (breeding experiments) analyses were conduc...
The phylogenetic position of the Olkhon mountain vole (Alticola olchonensis Litvinov, 1960) was studied using the sequences of four nuclear (BRCA, GHR, LCAT, and IRBP) and one mitochondrial (cyt. b) gene. Until now multiple studies of the systematic position of this vole had been based exclusively on morphological data, while the major taxonomic re...
Recent palaeogenetic studies indicate a highly dynamic history in collared lemmings (Dicrostonyx spp.), with several demographical changes linked to climatic fluctuations that took place during the last glaciation. At the western range margin of D. torquatus, these changes were characterized by a series of local extinctions and recolonizations. How...

Przewalski’s horses (PHs, Equus ferus ssp. przewalskii) were discovered in the Asian steppes in the 1870s and represent the last remaining true wild horses. PHs became extinct in the wild in the 1960s but survived in captivity, thanks to major conservation efforts. The current population is still endangered, with just 2,109 individuals, one-quarter...

The Pleistocene glacial cycles resulted in significant changes in species distributions, and it has been discussed whether this caused increased rates of population divergence and speciation. One species that is likely to have evolved during the Pleistocene is the Norwegian lemming (Lemmus lemmus). However, the origin of this species, both in terms...
Статья написана по следам дискуссий на совещании, посвященном современным проблемам биологической систематики, прошедшем в Санкт-Петербурге в апреле 2011 г. и адресована систематикам «классической» школы, испытывающим недоверие к молекулярным филогениям и трудности при сравнении с ними своих результатов. Рассматриваются этапы молекулярно-филогенети...
A range-wide phylogeographic study of the gray red-backed vole (Craseomys rufocanus), was carried out using cytochrome b and cytochrome oxidase subunit I of mtDNA and a fragment of the Y-chromosome SRY gene. The results, based on 271 specimens from 81 localities over the majority of the species distribution, demonstrate that there are four main mit...
The bank vole (Myodes glareolus) and the northern red-backed vole (M. rutilus) are two phylogenetically close
sylvatic species with a widely sympatric range (European part of Russia, Western Siberia). A significant number of M. glareolus with mitochondrial genome of M. rutilus was detected in this sympatry zone earlier and only one of the first gen...
