Multivariate analyses (nonmetric multidimensional scaling and multivariate allometry) were used to estimate a sexual size dimorphism (SSD) in cranial characters. A high degree of the sexual dimorphism was found in the Altai weasel population. All morphometric characters in the males were larger than those in the females. An average sexual size dimorphism (ASSD) of M. altaica lies within the genus Mustela range. In this species, the SSD is a result of differences in the scale and allometry of cranial characters between sexes, reflecting the differences in male/female allometric ontogenetic patterns. The results are discussed in relation to the existing hypotheses on sexual dimorphism in the mustelids: food competition, sexual selection, and differences in reproductive strategies.

During 2017–2018 we studied the reproduction of a common abundant species, the yellow-necked mouse Sylvaemus flavicollis, in oak communities to determine if the timing of reproduction has a predictive character during the autumn peak of reproduction. During the maturation of acorns the proportion of females in oestrus gradually decreased along with the share of males with reproductive activity. By the time the acorns were completely ripe and fell, the most of juveniles became independent, and a portion of the young females became sexually mature. In 2018, a high yield oak year, the sexual activity of the males was considerably higher than that in 2017, a moderate yield oak year, what can point on its role in the regulation of the intensity of reproduction. Thus, instead of any prediction, mating and pregnancy in a large proportion of the mice, began at the beginning of acorn ripening, due to females feeding on immature seeds, eliminating a delay between forage yield and rodent reproduction. A possible reason for this synchronization is the contents of triacylglycerols, the main constituents of body fat in animals, in the rodent diet. During the maturation of acorns, its proportion increases considerably, which can increase the survival rate of juveniles.

The upper second incisor is the largest among vestigial teeth and is less likely to be reabsorbed than the others. Growth duration for the majority of vestigial teeth is short (1–2 years). For most of the vestigial teeth, independent of the total number of cement layers and/or age of the walrus, only the enamel and partial upper part of dentine were worn off — without deforming any cementum layers. Generally the weight and width of the upper second incisor and the upper fourth premolar will increase relative to the number of annual cement layers added. For the majority of vestigial teeth examined, the number of cement layers coincided on pairs of teeth the same individual but seldom coincided with the number of cementum layers on other non-vestigial teeth.

The analysis revealed 112 ISSR bands, 101 of which were polymorphic. Seven ISSR primers ((AG)8 T, (GGAGA)5, (GACA)4, (TG)8 A, (CAG)5 GC, (CAG)4 AC and (GA)8 AC)) were optimized from total 20 primers. (AG)8 T and (GA)8 AC primers were most informative to distinguish cytotypes by producing specific bands for 2n = 54 and 2n = 60. The cytotypes in genetically close relationships were separated into three different groups by UPGMA cluster analysis, in which, the highest genetic diversity was measured for 2n = 60.

Thirteen copulatory behavior patterns that form a specific stereotype of the species’ mating behavior are used. The results showed the multiple thrusting stereotype of copulation, which includes separate intromissions and a very first mount with intromission, is ending with ejaculation (from 10% to 48%, depending by the investigated population). The number of ejaculations is comparatively big, varying from 4 to 7 (an average of 4.6) and the genital stimulation rate is from 68 to 260 thrusts. The males of the root vole noted active courtship for the female, which is accompanied by singing, waltzing and marking of the substrate. Marking the territory is manifested by rubbing the femoral region on the substrate, in which the secretion of the hip glands is applied to it. Analysis of the distances (or similarities) between species according to patterns of sexual behavior using the method of cluster analysis indicates the proximity of A. oeconomus to species of the genus Alexandromys and a considerable distance from representatives of the genus Microtus (Microtus s.str. and Sumeriomys). Significant interpopulation differences in copulatory behavior of the Central Asian phylogroup are established (54% of all the behavioral traits studied). The transformation of the stereotype of mating in individuals from Beringia phylogroup in comparison with the Central Asian one is particularly significant and reaches 77% of all the behavioral traits. The data obtained by the analysis of the copulatory behavior of the Alexandromys oeconomus support the separation of the species from genus Microtus.
