title: Herbivory simulations in ecological research.
abstract: Because of the experimental advantages that they offer, mechanical simulations of grazing are more commonly used than true herbivory in ecological studies of the impact of herbivory on plants. However, few studies have explicitly compared plant responses to herbivory and to mechanical simulations. Most such comparisons report differences in plant responses to mechanical versus true herbivory, even though the amounts and types of tissue removed were similar. Moreover, studies that also attempted to mimic the timing of leaf damage report differences in plant responses to the different damage modes. Because a plant's response to herbivory is complex and is activated by more than merely the removal of tissue, exact mechanical simulations may prove difficult.
