摘要：

Individual differences in the predicted foraging efficiency of forest-dwelling Cervus elaphus are used to assess the consequences for population demography. Growing animals experience restricted incisor breadth relative to weight during the transition from juvenile to mature dentition. A model of bite dimensions predicts that yearlings, male calves and stags will have the greatest reduction in foraging efficiency when feeding on depleted resources. This is corroborated by observed patterns of seasonal weight loss. Sex differences in growth strategy combined with the ontogeny and allometry of the incisor arcade may cause differential mortality between age and sex classes. -from Authors
