- ... 1. The impact of herbivores on plant fitness depends on multiple ecological mechanisms, including interactions between herbivore guilds. 2. This study assessed the effects of a specialist aphid (Aphis echinaceae) on performance and foliar herbivore damage of a long‐lived perennial plant (Echinacea angustifolia) native to the North American tallgrass prairie. A 2‐year field experiment manipulating ...

- ... Plants and their herbivores may influence each other's fitness and, hence, genetic dynamics, as well as their demography. Conversely, variation in fitness‐related traits may influence the occurrence or intensity of the interaction. Disentangling the fitness consequences of an interaction in nature from the influence of fitness variation on it is challenging, but important to clarifying the ecologi ...
