A revision of the genus Leopoldamys is presented, and both the species composition and distribution in Indochina and Sundaic regions is reinvestigated. The phylogeny of the genus is recovered based on Cyt b, COI, and IRBP gene analyses. Five basal and 16 secondary monophyletic phylogenetic lineages were identified. A taxonomic reassessment of the(More)
The central position in the division belongs to genera of Leopoldamys and Niviventer, which includes 6 and 17 species, respecc tively; the other genera are monotypic. Based on mitoo chondrial and nuclear genes phylogenetic analysis, the division Dacnomys is a monophyletic group [2] closely related to the divisions Rattus and Maxomys. Recently, genetic and(More)
To specify the taxonomic rank of form ciscaucasoides (independent species Sylvaemus ciscaucasoides, or intraspecific form of pygmy wood mouse, S. uralensis), a 402-bp the mtDNA cytochrome b gene fragment (402 bp) was examined in S. ciscaucasoides individuals from six geographic localities of the Caucasus and Ciscaucasus, (Krasnodar krai and Adygeya(More)
A natural focus of hantavirus infection was detected and examined during the studies conducted in 2000-2002 around the Sochi (the western spurs of the Great Caucasus Ridge, which descended to the Black Sea (the Krasnodar Territory of Russia). At least 4 rodent species, such as Microtus majori, A. (S.) ponticus, A. agrarius, A. (S.) ciscaucasicus, were shown(More)
In this review, we discuss the processes of fixation of Robertsonian chromosome fusions in populations of the common shrew Sorex araneus L. Various Robertsonian fusions, accumulating in populations, create an illusion of large chromosomal rearrangements, reciprocal translocations of complete chromosome arms. The use of these rearrangements for phylogenetic(More)
Based on molecular data for mitochondrial (Cyt b, COI) and nuclear (IRBP, GHR) genes, and morphological examinations of museum specimens, we examined diversity, species boundaries, and relationships within and between the murine genera Chiromyscus and Niviventer. Phylogenetic patterns recovered demonstrate that Niviventer sensu lato is not monophyletic but(More)
The taxonomic position of enigmatic pygmy dormouse Typhlomys (Rodentia: Platacanthomyidae) from Vietnam is reconsidered based on both morphology and sequence data. The analysis of mitochondrial and nuclear genes has shown that the pygmy dormouse from Lao Cai Province of northern Vietnam belongs to a distinct phylogenetic lineage of Typhlomys. The DNA(More)
In this work the genetic variability of the common shrew populations Sorex araneus L. in Eastern Europe was studied via mitochondrial gene cyt b sequencing. A total of 82 sequences of the mitochondrial gene cyt b with a length of 953 basepairs were analyzed, including five chromosome races in a continuous natural area in forest zone and two races which(More)
Tonkinomys daovantieni was recently described from Northern Vietnam, but very sparse information exists for the taxon. We report for the first time the karyotype of this species and investigate its phylogenetic position in the Dacnomys division using both mitochondrial and nuclear genetic data. The diploid chromosome number of the species is 2n=44. This(More)
