Male mating behaviour and patterns of sperm precedence in Arctic ground squirrels
Article Abstract:
The relationship between male reproductive success and mating behaviour was analyzed in populations of male Spermophilus parryii plesisius Arctic ground squirrels. Analysis of breeding success in male Arctic ground squirrels indicated the presence of significant variations in male mating behaviour which was dependent on male consortship order. Furthermore, female Spermophilus parryii plesisius that mated during the second and subsequent consortships did not generally produced an offspring.

Optimal body temperatures with shuttling: desert antelope ground squirrels
Article Abstract:
Analysis of the fluctuations in optimal body temperature during shuttling between two sites in desert antelope ground squirrels shows that the body temperature of squirrels leaving a burrow varies inversely with travel time and higher heating or cooling rates. The temperature also decreases with diminished body temperature while returning to the burrow and with increased rates of net energy gain.

Antipredator vigilance of juvenile and adult thirteen-lined ground squirrels and the role of nutritional need
Article Abstract:
Juvenile thirteen-lined ground squirrels, Spermophilus tridecemlineatus are not as vigilant as adults. Two groups of free-ranging juveniles were supplemented to determine if nutritional needs was a possible cause of the difference. The study found that lower vigilance of juveniles is due in part to the higher nutritional needs of young animals.
