Insect herbivores can cause significant damage to plants, resulting in reduced plant performance, mortality, and/or changes in plant population and community dynamics. Insect herbivores are often viewed as pest species if they cause harm to native or economically important plants. Alternatively, insect herbivores may be considered beneficial species if they help regulate populations of non-native invasive plant species.

Anthropogenic disturbances, such as pollution and climate change, can alter plant susceptibility to insect herbivore damage, and more generally, ecological interactions between plants and their insect herbivores.

Research in the Jamieson lab focuses on understanding how various abiotic and biotic factors influence plant-herbivore interactions. We are studying how these factors alter the ability of plants to tolerate or defend against insect herbivores.

Ongoing research projects examine a variety of native, invasive, and agronomically important plant and insect species.
