Abstract During the summers of 1977, 1978 and 1979, I investigated killing of infants and young juveniles (for simplicity referred to herein as infanticide) and paternal behaviour in a population of Arctic ground squirrels, Spermophilus parryii , near Haines Junction, Yukon Territory. Males defended territories primarily during the period when young ground squirrels were mot susceptible to being killed. Killing was most likely after removal of males that had been resident during the mating… Expand
Territoriality and male reproductive success in arctic ground squirrels
TLDR
It is suggested that future studies of vertebrate mating systems will benefit by viewing territorial defense as only one of multiple axes along which conspecific males compete for access to females. Expand
Male mating behaviour and patterns of sperm precedence in Arctic ground squirrels
TLDR
Comparison of sperm precedence patterns in ground squirrels may yield insights into the evolution of interspecific variation in male mating behaviour. Expand
Why do female Belding's ground squirrels disperse away from food resources?
TLDR
It is proposed that juvenile female, but not juvenile male, S. beldingi may emigrate from the natal site to increase access to areas with low densities of conspecifics, suggesting that competition for non-food resources was unusually intense in provisioned areas. Expand
The functional significance of infanticide in a population of California ground squirrels (Spermophilus beecheyi)

TLDR
Infanticide in this population of California ground squirrels may best fit the resource exploitation hypothesis, in which killers commit infanticide to gain a nutritional benefit. Expand
Alarm Calling in Richardson's Ground Squirrels (Spermophilus richardsonii)
TLDR
It is concluded that alarm calling by Richardson's ground squirrels is nepotistic rather than manipulative, which is supportive of the hypothesis that alarmCalling is maintained by kin selection. Expand
Field evidence for sexual selection and resource competition infanticide in white-footed mice
TLDR
The results support the sexual selection hypothesis for males and resource competition hypothesis for females, and suggest exploitation of young as a food source may occur opportunistically but does not appear to be the main motivation for infanticide. Expand
Reproductive effort during gestation and lactation by Richardson's ground squirrels
TLDR
Richardson's ground squirrels have a similar offspring mass relative to maternal mass both at birth and at emergence from the natal burrow, but because of the large litter size, absolute reproductive effort, measured either as litter mass at birth or at natal emergence, is large for the body size of the species. Expand
Nonparental infanticide in meadow voles, Microtus pennsylvanicus: the influence of nutritional benefits
TLDR
It is suggested that nutritional gains are an occasional but not the main motivation of pupkilling behaviour in female meadow voles, and the attainment of nutritional benefits could be one main benefit of infanticide by male meadows voles. Expand
Infanticide in tree squirrels - a male reproductive strategy?
TLDR
The lack of male - male competition over mates in the tree squirrel, as well as seasonal breeding in certain ranges of this species, lead me to conclude that infanticide does not represent a sexually selected male reproductive strategy. Expand
REPRODUCTION AT ALL COSTS: THE ADAPTIVE STRESS RESPONSE OF MALE ARCTIC GROUND SQUIRRELS
TLDR
It is concluded that breeding male arctic ground squirrels exhibit an adaptive stress response in which they trade off survival for reproduction, and similar stress re- sponses may have evolved in other species with comparable life histories. Expand

Differences in Weight Changes and the Annual Cycle of Male and Female Arctic Ground Squirrels

Population Control in Arctic Ground Squirrels
TLDR
Unlike most tundra rodents, the arctic ground squirrel, Spermophilus undulatus, maintains a relatively constant population and has two distinct types of territories: breeding territories from May to August and prehibernation territories from August to November. Expand
Aggression, ectoparasitism, and other possible costs of prairie dog (Sciuridae, Cynomys spp.) coloniality.
TLDR
It is concluded that there are probably several costs associated with prairie dog coloniality, that the severity of some of the costs correlates positively with colony or ward size for both White-tails and Black-tails, and that some ofThe costs are probably more pronounced for Black-tail than for White-tail.

Infanticide as an alternative male reproductive strategy in langurs: a mathematical model.
TLDR
A mathematical model has been developed from assumptions underlying the view that infanticide is one of two alternative reproductive strategies utilized by adult male langur monkeys (genus Presbytis), and formulae derived which give the equilibrium proportion of infanticidal males expected in langur populations under any given set of reproductive and demographic conditions.

TLDR
It is hypothesized that the threat posed by infanticide is one of several pressures selecting for a shift among higher primates away from strictly cyclical estrous receptivity towards socially determined or situation-dependent receptivity. Expand

Paternity and the evolution of male parental care.
TLDR
Paternity differences between species cannot serve as a general explanation for the observed patterns of parental care behavior and differences in reliability of parentage between males and females are unlikely to explain the prevalence of female care. Expand
