Relatedness within nest groups of the southern flying squirrel using microsatellite and discriminant function analyses
TLDR
This is the 1st study to show that adult nestmate southern flying squirrels typically are unrelated and do not nest in family-based groups.Citations

Climate change induced hybridization in flying squirrels
Colin J. Garroway,Jeff Bowman,Tara J. Cascaden,Gillian L. Holloway,Carolyn G. Mahan,Jay R. Malcolm,Michael A. Steele,Gregory G. Turner,Paul J. Wilson +8 more
TL;DR: In this paper, the authors identified the occurrence of hybridization between sympatric G. sabrinus and G. volans and found evidence of backcrossing but not of extensive introgession consistent with the hypothesis of recent rather than historic hybridization.

The influence of group size on natal dispersal in the communally rearing and semifossorial rodent, Octodon degus
TL;DR: The probability of dispersal increased with increasing number of degus per main burrow system used, a measure of habitat saturation in degus, and mean fecal metabolites of cortisol in offspring increased, yet not statistically significantly, with the number of juveniles in groups.

Familiarity with neighbours affects intrusion risk in territorial red squirrels
Erin R. Siracusa,Stan Boutin,Murray M. Humphries,Jamieson C. Gorrell,David W. Coltman,Ben Dantzer,Jeffrey E. Lane,Andrew G. McAdam +7 more
TL;DR: In this article, the authors investigated the importance of the composition of the social environment in a territorial species by assessing whether the risk of intrusion faced by territory owners varied with the degree of relatedness and familiarity in their social neighbourhoods.
Journal ArticleDOI
On the dynamics of rodent social groups.
TL;DR: The tenet that natal philopatry is the main process driving group dynamics in rodents may be premature, and studies aimed at examining the importance of alternative mechanisms are justified.
Journal ArticleDOI
Complex social structure of southern flying squirrels is related to spatial proximity but not kinship
TL;DR: It is hypothesized that minimum group size requirements associated with social thermoregulation could explain the absence of this species in patchy landscapes and aspects of range boundary dynamics near their northern range boundary.

The evolution of social behavior
TL;DR: For several years the study of social behavior has been undergoing a revolution with far-reaching consequences for the social and biological sciences, partly due to growing acceptance of the evidence that the potency of natural selection is overwhelmingly concentrated at levels no higher than that of the individual.
Journal ArticleDOI
Estimating relatedness using genetic markers.
TL;DR: A new method is described for estimating genetic relatedness from genetic markers such as protein polymorphisms based on Grafen's (1985) relatedness coefficient, which eliminates a downward bias for small sample sizes and improves estimation of relatedness for subsets of population samples.
Journal ArticleDOI
Food Hoarding in Animals
TL;DR: In this paper, a comprehensive synthesis of the literature on food hoarding in animals is presented, including how animals store food, how they use food and how this use affects individual fitness, why and how food hoarders evolved, how cached food is lost, mechanisms for protecting and recovering cached food, physiological and behavioral factors that influence hoarding, and the impact that hoarding animals have on plant populations and plant dispersal.
