Inland Lakes Monitoring Scientist/Lake Partner Program Coordinator
Ministry of the Environment, Conservation and Parks
Anna DeSellas is the Inland Lakes Monitoring Scientist with the Ministry of Environment, Conservation and Parks (MECP). Her responsibilities include coordinating the MECP’s Lake Partner Program, engaging citizen scientists to collect long-term water quality information about their lakes, collaborating with stakeholders on projects that support science communication and environmental stewardship outreach, and providing scientific expertise within and outside of the MECP.
Anna graduated in 2004 with a BSc (Honours) in Ecology and Environmental Biology from the University of Waterloo, and in 2006 with an MSc degree from Queen’s University. Her MSc thesis examined environmental stressors (such as calcium decline) and their impacts on the zooplankton (Cladocera) communities of a subset of lakes in the Muskoka-Haliburton region of Ontario. Anna began working at the MECP’s Dorset Environmental Science Centre in 2007, first on contract working on Lake of the Woods water quality topics, and then in 2009 as MECP scientist and Lake Partner Program coordinator. Eager to build on her scientific background and enhance her expertise, in 2016 she began a PhD with Queen’s University as a part-time student. Her doctoral thesis examines water quality changes over time in Algonquin Provincial Park using paleolimnology as a tool. One goal of this research is to differentiate the underlying causes of long-term change within the cladoceran communities, such as those caused by local stressors (such as cottage impacts), other stressors acting at a regional scale (such as climate change and calcium decline) and natural variability. These results may ultimately help to inform future management decisions and policies for Ontario’s provincial parks in the future.
In her personal time, Anna enjoys spending as much time outdoors as possible with her husband, four kids (including twins), and their dog, Nova.
