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)
251 The division Dacnomys (Rodentia, Muridae) of tribe Rattini includes six genera (Dacnomys, Niviventer, Leopoldamys, Chiromyscus, Srilankamys, and Anony momys). These genera inhabit Indochina, Sunda Isles, Sri Lanka, and Philippines [1].The central position in the division belongs to genera of Leopoldamys and Niviventer, which includes 6 and 17 species,(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)
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)
Cytogenetic analysis of the common shrew populations in the Valdai Hills revealed the presence of four distinct chromosome races (Western Dvina, Seliger, St. Petersburg, and Moscow). The geographic distribution of these races relative to the borders of the Late Valdai glaciation area is described and discussed. Five contact zones between chromosomal races(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)
To specify the taxonomic rank of form ciscaucasicus (independent species Sylvaemus ciscaucasicus, or intraspecific form of pygmy wood mouse, S. uralensis), a 402-bp the mtDNA cytochrome b gene fragment (402 bp) was examined in ciscaucasicus individuals from six geographic localities of the Caucasus and Ciscaucasus (Krasnodar krai and Adygeya Republic) and(More)
The species composition of the genus Niviventer was studied. The presence of at least 15 species in the genus, 8 of which represent the fauna of Vietnam, was confirmed. Based on an analysis of the cytochrome gene b of mtDNA, an attempt at distinguishing natural inter-genus groups was made and questions of inter-genus taxonomy were discussed.
396 The hypothesis on the Valdai ice sheet has repeatedly raised doubts because of flora endemism in the glaciation area of northwestern Europe [1] and because of strangely rapid forest recovery during the postglacial period in spite of the slow natural dispersal of woody species [2]. In terms of the traditional geomorphologic notion of the ice sheet, the(More)
