Four experiments were conducted to determine how experience around the time of natal emergence affected the development of litter-mate preferences in juvenile Belding's ground squirrels, Spermophilus beldingiSocial preferences were ascertained by observing six captive groups, each housed in outdoor enclosures beginning at natal emergence, and recording the frequency of dyadic play. Juveniles preferred their litter-mates as play partners on day 1 above-ground, demonstrating that pre-emergent… 

How mothers influence the development of litter-mate preferences in Belding's ground squirrels

It is demonstrated that the presence of S. beldingi mothers is important to juvenile social development, but that mothers do not actively direct the ontogeny of their offsprings' social relationships.

Retention of social recognition after hibernation in Belding's ground squirrels

In captive Belding's ground squirrels, yearling males did recognize their siblings, suggesting that the relative costs of maintaining kin-recognition abilities year-round may be low, and selection may not favour retention of individual memories of particular conspecifics over the winter.

Juvenile Richardson's Ground Squirrels (Spermophilus richardsonii) Manifest Both Littermate and Neighbour/Stranger Discrimination

Staging interactions in a neutral arena between littermate, neighbour and non-neighbour (stranger) pairs of otherwise free-living juvenile Richardson's ground squirrels demonstrated that juveniles come to discriminate neighbours from strangers.

Olfactory preference for own mother and litter in 1-day-old rabbits and its impairment by thermotaxis.

Rabbit pups can recognize olfactory cues emanating from their mother and their siblings the day after birth, and the preference for nesting materials would reflect in major part the combined attraction to maternal and sibling odors present in the nest.

Kin discrimination by asocial Franklin's ground squirrels (Spermophilus franklinii): is there a relationship between kin discrimination and ground squirrel sociality?

It is apparent that kin discrimination is not unique to highly social ground squirrels, and that strict kin discrimination may give way to broader social inclusivity with advancing sociality in the genus Spermophilus.

Self-referent phenotype matching and long-term maintenance of kin recognition

Fine-scale genetic structure and parentage in Urocitellus beldingi

Maternity can be deduced by observing female burrows usage during gestation and which offspring first emerge from the burrow associated with that particular female, and paternity can be posited by observation of mating because the species exhibits multiple mating in both sexes.

Recognition systems and biological organization: The perception component of social recognition

Recognition of conspecifics is necessary for differential treatment of individuals in a variety of social contexts, such as territory establishment and defense, dominance hierarchies, reciprocal

The results of this study support the hypothesis that kin favouritism develops from early social interactions involving dams and littermates in captive Belding's ground squirrels, and suggest that interactions between littermates prior to or just after emergence affected the development of social preferences.

The ontogeny of littermate preferences in juvenile golden-mantled ground squirrels: effects of rearing and relatedness

The social preferences of captive, juvenile golden-mantled ground squirrels, S. lateralis, were studied as a first step towards explaining the development of kin-differential behaviour, which occurs frequently in the genus Spermophilus.

Ontogeny of spatial relationships and social behaviour in juvenile Richardson's ground squirrels

The development of spatial and social patterns by juvenile Richardson's ground squirrels, from first emergence from the natal burrow to entry into hibernation, is described. Juveniles enter the

The Ontogeny of Kin Recognition in Two Species of Ground Squirrels1

The laboratory work shows that in both species, preweaned pups reared together, whether they are biological siblings or cross-fostered (unrelated) nestmates, are equally aggressive in subsequent paired arena tests, so pups that share a natal nest are treated like siblings.

Why male ground squirrels disperse

When they are about two months old, male Belding’s develop the idea that natal dispersal, like other behaviors ground squirrels leave the burrow and phenotypic attributes, can be understood from mulwhere they were born, never to return.

Social Behavior and Social Organization in Richardson's Ground Squirrel (Spermophilus richardsonii) in Saskatchewan

Richardson's ground squirrels, Spermophilus richardsonii, are territorial in Saskatchewan and young males had a greater tendency to disperse than any other age and sex, a tendency which would promote outbreeding in a population where related females maintain the same territory from year to year.

Behaviour and use of space by juvenile Columbian ground squirrels (Spermophilus columbianus)

Although there was no difference in the mean distance from the mother for males and females, females greeted their mothers three times more frequently than did brothers and females remained nearest their sisters and rates of play between sisters were the highest of all interacting pairs.

Social interaction with siblings is necessary for visual imprinting of species-specific maternal preferences in ducklings (Anas platyrhynchos).

No visual preference for the familiar mallard model was found at 48 hr or at 72 hr if ducklings were reared in social isolation but allowed to see another duckling, reared with one ducklings, or rearing in a group of ducklings but denied the opportunity for direct social interaction.

Body size, body composition, and behavior of juvenile Belding ground squirrels

The biology of juvenile Belding ground squirrels, Spermophilus beldingi beldedi, from a population residing at high altitude in the Sierra Nevada of central California is presented.

Proximal Causes of Natal Dispersal in Belding's Ground Squirrels (Spermophilus Beldingi)

Study of the proximal factors influencing dispersal from the natal site in two free—living populations of Belding's ground squirrels in the Sierra Nevada of California found dispersal is apparently not caused by changes in juveniles' response thresholds to conspecific aggression or by juveniles' attempts to avoid members of their family units, nearest neighbors, or otherMembers of their local populations.
