Phylogeny of Oriental Voles (Rodentia: Muridae: Arvicolinae): Molecular and Morphological Evidence

Zoological Science, 2012
The systematics of Oriental voles remains controversial despite numerous previous studies. In this study, we explore the systematics of all species of Oriental voles, except Eothenomys wardi, using a combination of DNA sequences and morphological data.

Radiation events in the subfamily Arvicolinae (Rodentia): Evidence from nuclear genes

Doklady Biological Sciences, 2009
Voles and lemmings (subfamily Arvicolinae) areone of the youngest and speciesrich groups of myomorphic rodents prevailing in different landscapezones of the northern hemisphere. Because of unprecedented fossil records, as well as rapid and continuingmorphogenesis, they became leading forms in correlation and biostratigraphy of late Cenozoic ...

Biochemical comparisons in holarctic lemmings of the genera Dicrostonyx and Lemmus (rodentia: Arvicolinae)

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1978
Abstract 1. 1. Hemoglobin (Hgb), transferrin (Tf), glucose-6-phosphate dehydrogenase (G6PD), and leucine aminopeptidase (LAP) were examined by starch-gel electrophoresis in Asian and North American populations of Dicrostonyx torquatus and Lemnus sibiricus . 2. 2. Holarctic D.

Multilocus systematics and non-punctuated evolution of Holarctic Myodini (Rodentia: Arvicolinae)

Molecular Phylogenetics and Evolution, 2014
The tribe Myodini consists of five genera of forest and alpine voles (Alticola, Caryomys, Eothenomys, Hyperacrius and Myodes) distributed throughout the Holarctic. Because mitochondrial evidence has revealed paraphyly and polyphyly among genera, we apply the first multilocus tests to clarify taxonomy and phylogenetic relationships.

Population dynamics and spatial behaviour of Microtus tatricus (Arvicolinae, Rodentia)

Acta Theriologica, 2010
The population dynamics of the Tatra vole Microtus tatricus (Kratochvil, 1952) (Arvicolinae, Rodentia) was monitored as part of a long-term study (1996–2008) of demography of small mammals conducted in Western Tatra Mountains—Rohace, Slovakia. We observed low abundance and population densities and a balanced sex ratio but slightly more frequent ...

Genetic diversity of Chionomys genus (Mammalia, Arvicolinae) and comparative phylogeography of snow voles

Russian Journal of Genetics, 2013
In the present study, the genetic polymorphism of the Chionomys genus was examined based on the sequencing of the mitochondrial cytb gene and two nuclear exons, including CHR exon 10 and BRCA1 exon 11. The distinct subdivision of the genus of snow voles into five lineages, including Ch. nivalis, Ch. gud, Ch. roberti, and Ch. aff.

Ontogenetic and evolutionary trends in the tooth enamel features in Craseomys voles (Arvicolinae, Rodentia)

Doklady Biological Sciences, 2016
In Craseomys rufocanus and Craseomys rex, the age-related and species differences in thickness and microstructure of the first lower molars (ml) have been identified and studied. The results suggest that the enamel dimensional and microstructural features may serve as additional indicators of the vole tooth evolutionary stage within a single phyletic ...

Prenatal Growth and Development of the Water Vole Arvicola amphibius (Rodentia, Arvicolinae)

Biology Bulletin
The morphological and morphometric characteristics of water vole embryos are studied. Embryo implantation occurs on the 5th day of pregnancy. A description of the morphological features of embryonic development at different stages of pregnancy is given, with equations for embryo body weight and length revealed.
