植物将其碳和氮资源分配给各种功能，包括构建和维持新组织（根，芽，生殖），储存和防御食草动物。有一个遗传决定的时间表，资源分配到各种功能，可以在一定程度上修改环境条件。的命题是检查，这个时间表代表了不断变化的分配优先级在工厂内的时间“窗口”时，它是比别人更容易受到草食动物的损害。反草食动物的“战略”的植物必须考虑到不断变化的模式，资源的可用性，以整个工厂和这些资源的分配，以提高生殖输出。
Plants allocate their carbon and nitrogen resources to a variety of functions including constructing and maintaining new tissues (root, shoot, reproductive), storage, and defense from herbivores. There is a genetically-determined time schedule of allocation of resources to various functions which can be modified to a certain degree by environmental conditions. The proposition is examined that this time schedule represents changing allocation priorities within the plant which results in time "windows" when it is more susceptible to herbivore damage than others. Anti-herbivore "strategies" of plants must be considered in relation to changing patterns of resource availability to the whole plant and in relation to allocation of these resources to enhance reproductive output.
