Territoriality and male reproductive success in arctic ground squirrels

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.

Male mating behaviour and patterns of sperm precedence in Arctic ground squirrels

Comparison of sperm precedence patterns in ground squirrels may yield insights into the evolution of interspecific variation in male mating behaviour.

Why do female Belding's ground squirrels disperse away from food resources?

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.

Alarm Calling in Richardson's Ground Squirrels (Spermophilus richardsonii)

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.

Reproductive effort during gestation and lactation by Richardson's ground squirrels

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.

Nonparental infanticide in meadow voles, Microtus pennsylvanicus: the influence of nutritional benefits

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.

Infanticide in tree squirrels - a male reproductive strategy?

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.

REPRODUCTION AT ALL COSTS: THE ADAPTIVE STRESS RESPONSE OF MALE ARCTIC GROUND SQUIRRELS

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.

Environmental Influences on Infanticide in Columbian Ground Squirrels

Evidence of infanticide of weanling ground squirrels was uncommon, except for one population and year (previously supplemented population at 1580 m elevation in 1984) in which 9 dead young were found, suggesting an increased rate of infamicide.

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

These data are interpreted in terms of the mating period which for males lasts for approximately three weeks, whereas for females it lasts for less than a day, and male/female differences, weights, annual cycle.

Population Control in Arctic Ground Squirrels

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.

Aggression, ectoparasitism, and other possible costs of prairie dog (Sciuridae, Cynomys spp.) coloniality.

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.
