The neurotransmitter serotonin is implicated in the regulation of various forms of behavior, including aggression, sexual behavior and stress response. The rate of brain serotonin synthesis is determined by the activity of neuronal-specific enzyme tryptophan hydroxylase 2. The missense C1473G substitution in mouse tryptophan hydroxylase 2 gene has been(More)
Comparative analysis of the structure of small mammal communities has been performed in two European cities located in different biomes: Chisinau (2008–2009) and Yaroslavl (1994–2002). The parameters studied included abundance, species composition, similarity and difference of faunas, species diversity, and proportions of groups differing in predisposition(More)
We used two methods to study the responses of representatives of three subspecies (Mus musculus musculus, M. m. wagneri, M. m. gansuensis) to the olfactory signals of con- and heterospecific individuals: (1) paired presentation of odor sources; and (2) modification of the “habituation” method—“habituation generalization.” To confirm the data obtained with(More)
The degree of development of the mechanisms of postcopulatory isolation was evaluated on the basis of experimental hybridization of representatives of three subspecies of M. musculus (M. m. musculus, M. m. wagneri, and M. m. gansuensis) and remote populations of the subspecies M. m. musculus. Experimental crosses between the different subspecies and(More)
The role of invasions in formation of the phylogeographic structure of a synanthropic species of house mouse (Mus musculus) is investigated. The probable ways of its expansion in some areas of Russia and the near abroad are analyzed. The genetic variability of subspecies and populations of M. musculus is evaluated by the data on polymorphism of the(More)
Macrosmatic animals (dogs and mice) have been proved to be able to distinguish between the urine or feces of mice with transplanted hepatocellular carcinoma and those of healthy mice by odor. The chemical composition of animal excreta was found to change with tumor growth; however, it is not clear yet if this results from tumor growth itself, inflammation,(More)
Analysis of the control region of mitochondrial DNA (mtDNA) or D-loop of 96 house mice (Mus musculus) from Russia, Moldova, Armenia, Azerbaijan, Kazakhstan, and Turkmenistan has been used to reconstruct the phylogenetic relationships and phylogeographic patterns of intraspecific forms. New data on the phylogenetic structure of the house mouse are presented.(More)
In this study, we investigate the influence of a mother on the behavior of young rabbits during the prepubertal period. It is shown that the presence of the mother affects the ratio of types of activity in offspring and the mother can demonstrate behavioral patterns to suppress aggressive behavior in offspring. It was found that rabbits in the prepubertal(More)
It was demonstrated that in Y-maze individuals of the outdoor species Myodes glareolus and the semi-synanthropic species Microtus levis avoided the urine odor of commensal Mus musculus. On the contrary mice stayed longer in the maze compartment with the odor of voles. The level of avoidance of commensal mice odor was higher than the other strange odors(More)
One of most important evolutionary consequences of commensalisms and invasions in house mice is formation of hybrid zones of different kinds: a narrow 16–50 km wide zone of introgressive hybridization between M. musculus and M. domesticus in Central Europe, a well-studied “tension zone” of secondary contact; large complex hybrid zone in(More)
