Plant secondary metabolites (PSM s) are ubiquitous in plants and play many ecological
roles. Each compound can vary in presence and/or quantity, and the composition of the …

Herbivorous insects use diverse feeding strategies to obtain nutrients from their host plants.
Rather than acting as passive victims in these interactions, plants respond to herbivory with …

Every plant is a member of a complex insect community that consists of tens to hundreds of
species that belong to different trophic levels. The dynamics of this community are critically …

Plants and herbivores are remarkably variable in space and time, and variability has been
considered a defining feature of their interactions. Empirical research, however, has …

The performance and population dynamics of insect herbivores depend on the nutritive and
defensive traits of their host plants. The literature on plant–herbivore interactions focuses on …

Many biologists now recognize that environmental variance can exert important effects on
patterns and processes in nature that are independent of average conditions. Jensen's …

The news that a flowering weed—mousear cress (Arabidopsis thaliana)—can sense the
particular chewing noise of its most common caterpillar predator and adjust its chemical …

Induced resistance is now widely accepted as a potent and widespread ecological force
although several pieces of the story remain very poorly known. Theory predicts that induced …

Plant resistance to herbivores was induced in a field experiment to evaluate the
consequences of induced responses for subsequent herbivory and plant fitness. Induction …

Research on the ecological and evolutionary roles of phytochemicals has recently
progressed from studying single compounds to examining chemical diversity itself. A key …
