Аннотация: The relationships between the body mass, date of emergence and frequency of social contacts in juveniles of long-teeth ground squirrel were studied. The body mass and date of emergence varied strongly among litters,and both factors affected the social activity of pups: the earlier juveniles emerged and the greater was their body mass at emergence, the higher was their social activity. However, this effect was pronounced only when both factors were combined: pups that had the greater body mass and emerged earlier interacted more frequently than pups that emerged later and had the lower body mass. The higher level of the social activity was not accompanied by a decrease in the rate of the body mass gain. On the contrary, pups that played demonstrated the higher body mass gain rate. Such a disturbance of the principle of energy and time allocation, when competing activities correlated positively, may be due to the unequal distribution of resources among litters, when some of them have redundant resources in terms of time and energy while others lack both.
