Relaxation of herbivore-mediated selection drives the evolution of genetic covariances between plant competitive and defense traits.

Abstract excerpt

Insect herbivores are important mediators of selection on traits that impact plant defense against herbivory and competitive ability. Although recent experiments demonstrate a central role for herbivory in driving rapid evolution of defense and competition-mediating traits, whether and how herbivory shapes heritable variation in these traits remains poorly understood. Here, we evaluate the structure and...
