“…Strong sex differences in at least one measure of direct parental care, licking pups, were found for steppe lemmings (Eolagurus luteus (Eversmann, 1840) - Smorkatcheva et al, 2011;Lagurus lagurus (Pallas, 1773) -Gromov, 2010Smorkatcheva et al, 2011), using both undisturbed observations in small home cages and parent-litter separation paradigm. Although the characteristics of mating system of steppe lemmings are poor known, there are some evidences of pairbonding and living in family groups (Malkova et al, 2004;Evsikov et al, 2006;Smorkatcheva et al, 2009). Given together, these data hint that phylogeny rather than mating system may affect the sex differences in parental responsiveness (Smorkatcheva et al, 2011), and that promiscuous voles of genus Microtus readily exhibit paternal care, at least after the short period of exposure to pups.…”

The relationship between parental care patterns and mating system in voles has not been fully elucidated. Whereas mating and parental strategies have been reported for many New World arvicolines, such information is lacking for most Palearctic voles. Nothing is known about the social organization of Microtus mongolicus inhabiting mesic habitats of Central Asia. We investigated spacing of free-ranging M. mongolicus in Zabaykalsky Kray using mark-recapture method, and we assessed the parental care exhibited by Mongolian voles in laboratory. Home ranges (HR) and movement distances of overwintered males exceeded those of other categories of voles. HR overlapped within sexes and between sexes in linear habitat at high population density as well as in non-linear habitat at low density. The revealed pattern of spacing is consistent with promiscuous mating system. In laboratory, both the parent-litter separation tests and undisturbed observations of animals in large enclosures showed that most males displayed paternal behavior at the level comparable to that of socially monogamous species. Our results demonstrate that monogamous mating system cannot be inferred from biparental care detected in captivity.

Mating system theory based on economics of resource defense has been applied to describe social system diversity across taxa. Such models are generally successful but fail to account for stable mating systems across different environments or shifts in mating system without a change in ecological conditions. We propose an alternative approach to resource defense theory based on frequencydependent competition among genetically determined alternative behavioral strategies characterizing many social systems (polygyny, monogamy, sneak). We modeled payoffs for competition, neighborhood choice, and paternal care to determine evolutionary transitions among mating systems. Our model predicts four stable outcomes driven by the balance between cooperative and agonistic behaviors: promiscuity (two or three strategies), polygyny, and monogamy. Phylogenetic analysis of 288 rodent species supports assumptions of our model and is consistent with patterns of evolutionarily stable states and mating system transitions. Support for model assumptions include that monogamy and polygyny evolve from promiscuity and that paternal care and monogamy are coadapted in rodents. As predicted by our model, monogamy and polygyny occur in sister taxa among rodents more often than by chance. Transitions to monogamy also favor higher speciation rates in subsequent lineages, relative to polygynous sister lineages. Taken together, our results suggest that genetically based neighborhood choice behavior and paternal care can drive transitions in mating system evolution. While our genic mating system theory could complement resource-based theory, it can explain mating system transitions regardless of resource distribution and provides alternative explanations, such as evolutionary inertia, when resource ecology and mating systems do not match.
