H.C. Duthie

Job Title: Professor
Employer: University of Waterloo
Further Education: Ph.D. (Wales)
Geographic focus of research: Ontario, Labrador

Brief synopsis of current research:
My research contributions in freshwater biology fall into three general areas: reservoir limnology, running water ecology, and paleolimnology. Past research in Churchill Falls, Labrador, and in northern Quebec resulted in the first comprehensive study of large subarctic reservoirs in Canada, and produced a predictive model of reservoir development. Research in running water is focused mainly on nutrient cycling, macrophyte and periphyton ecology, and pollution bioassessment. Ongoing research includes an export coefficient modelling approach to river eutrophication, and the assessment of point and diffuse nutrient sources in the Grand River. Research in paleolimnology involves mainly microfossil-inferred reconstructions of postglacial development. Current research focuses on the long-term development of Great Lakes shoreline wetlands and waterbodies, in particular the indentification of past climate and water level changes, and the assessment of anthropogenic impacts.
