Intraspecific competition facilitates the evolution of tolerance to insect damage in the perennial plant Solanum carolinense.

Abstract excerpt

Tolerance to herbivory (the degree to which plants maintain fitness after damage) is a key component of plant defense, so understanding how natural selection and evolutionary constraints act on tolerance traits is important to general theories of plant-herbivore interactions. These factors may be affected by plant competition, which often interacts with damage to influence trait expression and fitness. However,...
