Mate‐choice theory predicts different optimal mating systems depending on resource availability and habitat stability. Regions with limited resources are thought to promote monogamy. We tested predictions of monogamy in a social rodent, the hoary marmot (Marmota caligata), at the northern climatic extreme of its distribution. Mating systems, social structure and genetic relationships were investigated within and among neighbouring colonies of marmots within a 4 km2 valley near Kluane National… 
Mating system and paternity in woodchucks (Marmota monax)
TLDR
The mating system of woodchucks (M. monax), whose social organization lies at the opposite end of the continuum from alpine marmots, is described, which could be classified as genetically promiscuous.
Ecological, Evolutionary and Social Constraints on Reproductive Effort: Are Hoary Marmots Really Biennial Breeders?
TLDR
Hoary marmots are less conservative breeders than previously believed, and the evidence for biennial breeding throughout Marmota, and in other arctic/alpine/antarctic animals, should be re-examined.
Social and Genetic Mating Systems of the Asian Lesser White-toothed Shrew, Crocidura shantungensis, in Taiwan
TLDR
The hypothesis that the mating system of shrews in the subfamily Crocidurinae is monogamous in subtropical or tropical regions with seasonal climate and resource availability is rejected.
Paternity and male mating strategies of a ground squirrel (Ictidomys parvidens) with an extended mating season
TLDR
The results suggest that the mating system of the Rio Grande ground squirrel is best described as scramble competition polygyny, with the primary male reproductive strategy consisting of searching for estrous females.
Social Games and Genic Selection Drive Mammalian Mating System Evolution and Speciation
TLDR
The proposed genic mating system theory 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.
Characterizing habitat relationships and establishing monitoring strategies for an alpine obligate
Species that live in ecosystems with extremely different seasonal conditions must balance the constraints of each season to survive. Alpine species that do not migrate seasonally are especially adept

Of Apples and Oranges? The Evolution of “Monogamy” in Non-human Primates
TLDR
An overview of research on “monogamy” in mammals generally and primates in particular is provided, and it is proposed that a productive way to frame and dissect the different components of pair-living and sexual or genetic monogamy is by considering the behavioral and evolutionary implications of those components from the perspectives of all participants in a species' social system.
Bi-paternal litter in finn raccoon (Nyctereutes procyonoides Gray 1834) detected by polymorphic DNA markers.
TLDR
Novel results are demonstrated confirming the phenomenon of multipaternity in Finn raccoons using polymorphic microsatellite markers and indicates a necessity to check the origin of young animals selected for breeding stock in Finnish raccoon breeding farms.

Cooperative breeding in marmots
TLDR
This paper identifies cooperative breeding when: individuals delay dispersal beyond reproductive maturity, reproduction in mature individuals is suppressed, and when non-breeders provide alloparental care, and notes that marmots provide an excellent taxon in which to study the evolution of cooperative breeding.

The evolution of marmot sociality: I. Why disperse late?
TLDR
Prolonged toleration of offspring in marmots was hypothesized to be a means of preventing dispersal of undersized young, or more generally (2) continued parental investment, increasing the probability of descendant survival and reproduction, but these hypotheses are not supported.

ECOLOGY AND SOCIAL BEHAVIOR OF GOLDEN MARMOTS (MARMOTA CAUDATA AUREA)
TLDR
While general predictions about sociality in marmots were up­ held, an economic model combining defense costs and resource distribution failed to ex­ plain the mechanism of social monogamy.
Modelling the role of social behavior in the persistence of the alpine marmot Marmota marmota
TLDR
The lessons from the population viability analysis of the alpine marmot Marmota marmota are that simple, unstructured models may not be sufficient to assess the viability of species with complex behavioral traits, and that even moderate increases in habitat capacity may substantially reduce extinction risk even if environmental fluctuations seem high.
Kinship, reproductive strategies and social dynamics of yellow-bellied marmots
TLDR
Social behavior of yellow-bellied marmots was observed for three years in colonies where kinship was known and for one year in a high elevation colony where harems were contiguous, indicating that reproductive strategies limit nepotism.
Male reproductive success in a promiscuous mammal: behavioural estimates compared with genetic paternity
TLDR
A comparison of behavioural and genetic measures of male reproductive success in a mammalian mating system in which both sexes are highly promiscuous suggests that mating tactics differ between age groups, and that alternative mating strategies among adults that do not involve forming consorts with many females also confer mating success.
Social behavior of alpine marmots (Marmota marmota): seasonal, group, and individual variability
TLDR
The composition and social interactions of three family groups of Marmota marmota were observed during a study in the Vanoise National Park from mid-June to late September, confirming the social nature of this species.
