“…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).…”

“…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).…”

“…Type IV represents structural family groups with delayed offspring dispersal and complicated social organization related, for example, to hierarchy of subordination, differentiation of behavioral roles, suppression of reproduction in offspring, etc. Gray hamster is a solitary species (Type I) with sole maternal care and promiscuous mating (Gromov et al 2006;Gromov 2008). Red-backed vole is a gregarious species (Type II) with promiscuous mating and very weak paternal responsiveness that means mainly sole maternal care (Gromov 2008(Gromov , 2009a.…”

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.

“…By the year 2012, this stock had been bred for over 46 generations, and microorganisms and parasites within the stock had been well controlled through repetitive bio-rederivation procedures (Liao 2002). In addition, major physiological and biochemical indexes have been systematically evaluated for the stock population, including reproduction performance, social behavior, organ coefficient characteristics, hematologic parameters, basic metabolic traits and hibernation; genetic analysis has also been performed based on biochemical methods (Liao et al, 2000;Gromov et al, 2006;Romanenko et al, 2007;Ibiş et al, 2011). These fundamental works improve the potential for the application of this animal as a novel laboratory model.…”

ABSTRACT. The grey hamster has been used in biomedical research for decades. However, effective molecular methods for evaluating the genetic structure of this species are lacking, which hinders its wider usage. In this study, we employed cross-amplification of microsatellite loci of species within the same genus by polymerase chain reaction. Loci screened included 107 from the Mongolian gerbil (MG) and 60 from the Chinese hamster (CH); of these, 15 polymorphic loci were identified for the grey hamster. Of the 167 loci screened, 95 (56.9%) with clear bands on agarose gel were initially identified. After sequencing, 74 (77.9%) of these matched the criteria for microsatellite characteristics, including 41 from MG and 33 from CH. Lastly, 15 (20.3%) loci with more than two alleles for each locus were identified through capillary electrophoresis scanning. To justify the applicability of the 15 grey hamster loci, genetic indexes of grey hamsters were evaluated using 46 generations of outbred stock, established 20 years ago, from Xinjiang, China. Mean effective allele numbers and expected heterozygosity of stock were as low as, respectively, 1.2 and 0.14; these were 2.8 and 4.0 times inferior, respectively, 14339-14347 (2015) to wild grey hamsters. This finding suggests that the genetic structure of the stock-bred population is too weak to resist artificial and natural selection, mutation and genetic drifting. In conclusion, we have developed de novo microsatellite markers for genetic analysis of the grey hamster, providing data and methodology for the enrichment of a genetic library for this species.
