摘要

Many morphological and chemical features of plants are classified as plant defenses against herbivores. By definition, plant defenses should increase a plant's fitness (i.e., its contribution to the gene pool of the next generation) as a function of herbivory. Over the past years, substantial progress has been made in understanding and manipulating the mechanistic basis of many putative plant defense traits. However, most plant defenses are still characterized by proximate variables such as herbivore performance or plant damage rather than actual fitness. Determining fitness benefits as a function of herbivory therefore remains a major knowledge gap that must be filled to understand the ecology and evolution of plant defenses.
