Dr. Michelle Palmer will discuss how recent climatic warming, changes in acidic deposition, and human-related activities such as road salting and the accidental spread of invasive species have altered the water quality of our lakes in south-central Ontario, with a focus on changes in lake temperatures and water chemistry since the 1980s.

Michelle Palmer recently obtained her Ph.D. from York University.

Michelle’s research interests include understanding how ecosystems respond to multiple stressors. For her Ph.D., she investigated how 25 years of climate change, lakeshore development, road salting, acid rain, calcium decline, and invasive species have impacted lake temperature, water quality and zooplankton in approximately 40 lakes in south-central Ontario. Michelle is also interested in the ecology of invasive species and through her M.Sc. at McGill University she looked at the environmental factors that affect the relative abundance of invasive and native species.
