Both mammalian and insect herbivores may have a major impact on plant growth, reproductive capacity, and survival (McNaughton 1983, Bergelson and Crawley 1992a, b). Intensive grazing is therefore expected to favor plant adaptations that reduce either the risk of damage or the negative effects of damage on plant performance. Belsky et al. (1993) classified such adaptations into (1) avoidance strategies, including escape in time as well as chemical and mechanical defenses, and (2) tolerance strategies related to compensatory growth after damage (see also van der Meijden et al. 1988, Rosenthal and Kotanen 1994). Compensatory responses can vary considerably ...
