- Title
Effects of Preweaning Predatory or Consummatory Experience and Litter Size on Cricket Predation in Northern Grasshopper Mice (Onychomys leucogaster).
- Authors
Kemble, Ernest D.
- Abstract
Preweaning exposure to cricket killing and consumption, but not consumption alone, facilitated postweaning cricket predation. This facilitatory effect did not result from kill-sharing by the parents or from food competition among the offspring. The results were strongly influenced by litter size. Small litters (N = 3–4) were strongly facilitated in all measures of predatory behavior when compared to litters of five or six mice. Since smaller litters of this species also show much higher levels of play behavior, it is suggested that play frequency may strongly facilitate later predatory behavior.
