“…We reported singing during courtship in 50% of males from UP and in 60% of males from BP, as well as waltzing and marking in 60% and 70% of males, respectively, of both populations. Dewsbury and Hartung (1982) did not present data for these parameters from the Alaskan root vole population. However, Alaskan voles have hip glands which produce secretions for marking.…”

“…The percent of occurrence of first mount ejaculation in the males from BP and especially in those from UP compared with the males from AP was higher (Table) and the differences were significant (p<0.01). Dewsbury and Hartung (1982) reported that sometimes the first contact of voles ended with ejaculation, but, apparently, the number of such pairs was not more than 10%.…”

“…In our study during testing, the males were placed near caged females (cage dimensions 330 × 550 × 200 mm). Dewsbury and Hartung (1982) placed the females in the territory of the males. The experiment ended when the criteria for satiety in males, indicated by 30 min without copulation, was achieved.…”

The aim of the study was to evaluate the phylogeny and relationships of the root vole Alexandromys oeconomus with the other species of the tribe Microtini, using the comparison of the characteristics of sexual behavior. 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.

“…Dewsbury (1972Dewsbury ( , 1975 and Dixson (1998) each established a scheme to classify the pattern of copulatory behaviour, the latter mainly used in primates. Brandt's vole, like the California vole Microtus californicus, meadow vole M. pennsylvanicus, woodland vole M. pinetorum, root vole M. oeconomus and taiga vole M. xanthognathus, displayed pattern 11 (Dewsbury 1973, Gray and Dewsbury 1975, Dewsbury and Hartung 1982 in Dewsbury's classfication, and pattern 12 in Dixson's classfication.…”

Influence of operational sex ratio and density on the copulatory behaviour and mating system of Brandt’s voleMicrotus brandti

2003. Influence of operational sex ratio and density on the copulatory behaviour and mating system of Brandt's vole Microtus brandti. Acta Theriologica 48: 335-346.The pattern of copulatory behaviour of Brandt's vole Microtus brandti (Radde, 1861) is similar to patterns 11 and 12 as described by Dewsbury and Dixson: no lock, single intromission, thrusting after intromission and multiple ejaculations. Under constant density, when the operational sex ratio (OSR, male to female) was skewed to the males, the mating opportunity of males decreased due to mating interference, while the mating input of female remained the same; when the OSR was skewed to the females, male voles tended to increase mating input while females did not. Under the same OSR (1:1), when density increased, the mating opportunity of both sexes dramatically decreased due to mating interference between same sex individuals; the thrusting frequency of males increased, probably due to compensation for the decreased mating opportunity. There was a considerable probability of the voles forming monogamous and polygynous mating relationships. Our results did not support the prediction that when OSR is skewed to male, the mating interval of males will shorten. We suggest that the most predominant mating system and mating interference should be taken into account when investigating an OSR effect. Our study suggested that the Brandt's vole is prone predominantly to monogamy and polygyny. However, due to limitation of observation in the laboratory, further work should be combined with studies in the field.

“…To investigate this hypothesis, the present studies examined behavioural potentials and fertility in female gray-tailed voles of various ages that were isolated from males after weaning. In addition, because oestrogen is known to influence the vaginal epithelium, to increase during maturation of other rodents (Dohler & Wuttke, 1975), and to stimulate expression of receptive behaviours in voles (Dluzen & Carter, 1979;Dewsbury & Härtung, 1982), plasma concentrations of this hormone were measured in females of different ages, and in females of the same age showing different behavioural potentials.…”

Age-related changes in plasma oestrogen concentration, behavioural responsiveness to oestrogen, and reproductive success in female gray-tailed voles, Microtus canicaudus

Age-related increases in the incidence of vaginal cornification were associated with increases in the reproductive success of female gray-tailed voles previously isolated from males. The pregnancy rate of females first paired with males at 30-50 days of age was significantly lower than that of females first paired at 90-120 or 150-200 days of age. The improvement was due to increases in propensities to display receptive behaviours and decreases in the incidence of sterile matings. Although plasma oestrogen concentrations increased with age and were higher in receptive than unreceptive females, plasma oestrogen values alone did not account completely for differences in receptive behaviours amongst females of different ages. Females ovariectomized at 30-50 days of age rarely displayed receptive behaviours when treated with large doses of oestradiol benzoate, whereas nearly all females similarly treated were receptive if ovariectomies were performed between 150 and 200 days of age. The receptivity rate of females ovariectomized between 90 and 150 days was intermediate between the rates of the other two groups.
