It is widely accepted that the levels of resources in a plant’s environment can influence the plant’s ability to compensate for (i.e., tolerate) damage by herbivores. However, predicting the direction of the influence has proven difficult. Here, we report on a greenhouse study in which individuals of Solidago altissima were exposed to factorial combinations of light and fertilization levels to investigate how different types of stresses affect plants’ ability to tolerate leaf damage by larvae of the beetle Trirhabda virgata. Shade stress reduced the plants’ tolerance of herbivory, while nutrient stress had no effect on tolerance. These results did not …
