Research Interests

My main research interest is the biology of insect galls induced by cynipid wasps of the genus Diplolepis on the wild roses of Canada. Since 1968, I have been examining the life history strategies and zoogeography of the 14 species of Diplolepis found in Canada, ecology of the component communities associated with galls of each species of Diplolepis, and the developmental morphology and physiology of the galls of each Diplolepis species. I am also interested in the galls of other insects and, along with graduate students, have studied galls, for example, of the chalcid Hemadas nubilipennis on lowbush blueberry, the cynipid Phanacis taraxaci on dandelion, and the tephritid fly Urophora cardui on Canada thistle. I am also interested in the biology of Canada's wild roses and have begun studying the insect load on these shrubs and their anatomy and physiology.

As a sideline project, I have been studying since 1994, along with research associate Dr. Giuseppe Bagatto, the attributes of tailings associated with the nickel and copper mining companies of Sudbury. We have been examining the succession of plants on restored tailings, the accumulation of heavy metals in tailings plants, and the use of carabid ground beetles and mites as bioindicators of tailings health.
