“…Huddling over pups was not directly estimated in the species under study. Nevertheless, such a parameter as nest residence of parent individuals can be used as an appropriate index of huddling over pups because both male and female being in the nest spend not less than 80% of time in close side-by-side and other tactile contacts with infants (Gromov 2005b(Gromov , 2007Gromov et al 2006).…”

“…Besides, licking the ano-genital region of pups induces them to urinate and defecate (Rosenblatt and Lehrman 1963). Although pup grooming decreased during postnatal development, it did not disappear entirely at weaning in species with the family-group mode of life (Gromov 2005b(Gromov , 2007(Gromov , 2009a, when the above functions were no longer required. Therefore, pup grooming probably has an additional, social role, in maintaining the bond between parents and offspring.…”

“…To evaluate pair-bonding, such parameters as time that females shared natal nest with their male mates (minutes per 1 h) and duration of the mate grooming for both partners (seconds per 1 h) were used. Description of the methods is published elsewhere in detail (Gromov 2005b(Gromov , 2007(Gromov , 2009aGromov et al 2006).…”

“…Reproducing pairs and weakly consolidated family groups with biparental care of young and early offspring dispersal (Type III) are characteristic of common and social voles (Gromov 2007(Gromov , 2008. Both Brandt vole and Mongolian gerbil (Type IV) live in family groups with delayed offspring dispersal and complicated social structure (Gromov 2003(Gromov , 2005b(Gromov , 2008.…”

The cricetid rodents (hamsters, voles, and gerbils) show substantial inter-specific variation in their social organization, mating strategies, and patterns of social behavior, including parental care. In the present study, behaviors related to pair-bonding and parental activities were evaluated in male-female pairs of six cricetid species (Cricetulus migratorius Pallas, 1773, Clethrionomys rutilus Pallas, 1779, Microtus arvalis Pallas, 1778, Microtus socialis Pallas, 1773, Lasiopodomys brandti Radde, 1852, and Meriones unguiculatus Milne-Edwards, 1867) observed under laboratory conditions. These species were chosen due to particular differences in their mating strategies and the spatial-and-ethological population structure (Types I-IV). The results of the study show that there is a pronounced tendency towards both reinforcement of pair-bonds and increasing rate of direct parental care, especially paternal one, when solitary or gregarious species (Types I and II-C. migratorius and C. rutilus) are compared with the ones living in family groups (Type III-M. arvalis and M. socialis and Type IV-L. brandti and M. unguiculatus). Parental investment of males is mainly related to additional tactile stimulation of infants. A high level of tactile stimulation of pups promotes an increase in subsequent paternal care and reinforcement of pair-bonding, and, conversely, a deficit of tactile stimulation negatively affects the development of paternal behavior and social relationships. Thus, tactile stimulation can be regarded as one of the proximate mechanisms of socialization that plays an essential role in the evolution of sociality, i.e., transition to a family-group mode of life in rodents.

The tradeoff between parental effort and mating effort in male animals may be mediated by testosterone (T). The pattern of association between T and paternal care in birds is consistent with this hypothesis, while it is poorly studied and not universal for mammals. We used the correlation approach to test two predictions of T-mediated tradeoff hypothesis for a biparental vole, Microtus mandarinus: (1) that T levels in males decrease from before pair formation to after birth of the first litter and (2) that paternal responsiveness of males negatively correlates with their T levels. T concentrations were measured in fecal samples collected before pairing and then immediately before behavioral testing on day 5 after birth of the first litter. Both nonpaternal and low paternal males had high initial T that decreased after birth of pups, though the decrease was only significant in low paternal males. In highly paternal males, the initial T was low and did not change after birth. Our results support the predictions of T-mediated tradeoff hypothesis and reveal individual variation in hormone-behavior relationship.
