Ryerson Urban Water

Stephanie Melles is an Assistant Professor in the Department of Chemistry and Biology at Ryerson University. Dr. Melles graduated with a BSc in Ecology from University of Toronto, an MSc in Landscape Ecology from University of British Columbia, and a PhD in Spatial Ecology from University of Toronto. Dr. Melles has post doctoral research experience in both academic and government settings (Wageningen University, the Netherlands, Canadian Network for Aquatic Ecosystem Services at University of Toronto, NSERC Visiting Fellowship at Environment Canada, and Ontario Ministry of Natural Resources and Forestry at Trent University).

Stephanie is primarily interested in the question of what determines where organisms are located, both on land and in the water. Her research is focused on understanding the principle ecological drivers of dynamic species distribution and diversity patterns across a range of spatial-temporal scales.  She combines field-based observation with theoretical modelling and statistical simulation to unravel current and past ecological drivers of diversity. Dr. Melles is most interested in studies of how humans observe, modify, and control patterns of species distribution and diversity in different ecosystem types (e.g., urban lands and waters, rivers, lakes, forested, and agricultural systems).

Stephanie’s current work focuses on determining how climate change, urbanization, and invasive species lead to altered communities and extinctions across scales, which can have dramatic consequences for ecosystem diversity. She is also interested in how sampling design affects inference and the design of more (cost) effective sampling strategies.
