European Russia is a highly endemic area of hemorrhagic fever with renal syndrome (HFRS), a rodent-borne zoonotic disease, caused by hantaviruses. In total, 145 small mammals of four species (Myodes glareolus, Apodemus flavicollis, A. agrarius, and A. uralensis) were trapped in the Samara region of European Russia in August 2005 and examined for th...
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 chromosoma...
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 phyl...
The biotopical distribution and reproduction of the sibling species, Microtus arvalis and M. rossiaemeridionalis, and their interrelationships with the hantavirus Tula were studied within an anthropogenic forest-steppe landscape (Tula oblast) by seasons during three years. 332 specimens of both species were captured using 19.5 thousand trap-days. T...
Skulls in 504 one-year-old individuals of the common shrew, Sorex araneus, representing seven chromosomal races (Moscow, Lepel, Manturovo, Yagri, Tomsk, and Nerusa) were examined using 24 dimensions and 15 indices. Races were found to differ in a number of dimensions and proportions of skull. Each race has its own morphological appearance. The clus...
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 Republ...
Richard Goldschmidt has given the name “system mutation” to a large change in the karyotype resulting from translocations, inversions, and other rearrangement and leading to species isolation, though he assumed that the novel chromosomal structure develops gradually after a series of consecutive events [1, p. 200]. Goldschmidt assumed that speciati...
A total of 5149 small mammals belonging to 16 species were collected from the Lipetsk, Voronezh, and Belgorod regions (40 administrative districts) in 2003-2004 and examined by ELISA and IFA to detect hantavirus antigen and antibodies in the lung tissues. Hantavirus circulation was revealed in 13 species, the highest hantavirus activity being detec...
The karyotypes (routine, C-, Ag-NOR-banding) and haemoglobin patterns (using express electrophoresis) in sibling-species of the common vole, Microtus arvalis s. l., as well as in M. agrestis from the Voronezhskii State Reserve were studied for the first time. Twenty-six specimens among 43 ones investigated were found to belong to M. rossiaemeridion...
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).
