The conceptual aim underlying my research program has been to increase our understanding of ecological interactions of insects with plants in the dynamics, distribution and persistence of plant populations and communities. An additional goal has been to explore the application of these basic principles in natural resource management, such as in managing biotic response to environmental stress, conserving rare species, applying biological control to weeds, and managing exotic invasive species. My research has used an experimental field approach to assess interactions, especially the effects of plant-feeding insects on the growth, reproduction, population dynamics and community interactions of plants with their dependent insect guilds. My colleagues and I have also investigated ecological and biochemical mechanisms that mediate insect impact on plants.
