We showed previously for mice that size differences of the infrapyramidal hippocampal mossy fiber projection (IIP-MF) correlate with spatial learning abilities. In order to clarify the role of the IIP-MF in a natural environment, we studied the bank vole (Clethrionomys glareolus), adapted to a wide range of different habitats, and the root vole (Microtus(More)
Morphometric differentiation between the Manturovo and Serov chromosome races of the common shrewSorex araneus Linnaeus, 1758, in Northeastern European Russia was studied using 27 measurements of the skull in 953 specimens. Discriminant and cluster analyses showed that shrews belonging to different chromosome races were well differentiated. No regular(More)
The chromosomal race Serov of the common shrew ( Sorex araneus ) known in the Urals and Western Siberia was found for the first time in ten areas studied in the European Cis-Ural region at least 300 km west of the Ural Mountains. Diagnostic metacentrics (go, hn, ip, km, qr) were stable; karyotyping of 16 animals showed no polymorphism (2 n A = 18). This(More)
A new method for quantitative study of small mammals swimming across water obstacles was developed. A line of 25 traps was installed on either poles or boards (“rafts”) with anchors at a distance of 20–25 m from the bank and with 10-m distances between the items. The study was performed upstream along the Ilych River in August 2013. A total of 300 trap/day(More)
Long-term data sets on the population dynamics of forest voles in northern European Russia were analyzed. Eastward and northward trends in changes of the ratio between model species and the degree of their dominance were revealed. In virtually all sites studied, the numbers of the northern red-backed and bank voles changed synchronously; however, the(More)
