Research interests:

Jim Dunn's students are investigating the mechanisms of plant tolerance and defense to insect herbivory. They are investigating the role that plasticity in life history characteristics and carbon allocation patterns play in the tolerance of clonal milkweed to damage by monarch caterpillars. Individual ramets appear to tolerate damage by being part of a larger clonal system than can share resources. We are also investigating the effect of drought on the inducible resin response of milkweed.

We are also concerned with the conservation of endangered insects in Michigan. A current project is documenting the Homoptera species richness of the rare sand-pine prairies of Newaygo Co. by comparing remnant prairies with reconstructed prairies. We hope to determine a list of prairie obligate species that can be used to indicate community quality. Butterfly and Orthoptera surveys are also underway.
