Short Bio

Melissa McKinney received her BSc degree (Chemistry) from the University of British Columbia, her MS degree (Chemistry and Biochemistry) from the University of Windsor at the Great Lakes Institute for Environmental Research (GLIER), and her PhD (Chemistry, with Specialization in Chemical and Environmental Toxicology) with a Canada Graduate Scholarship from Carleton University at the National Wildlife Research Centre. She held an NSERC Postdoctoral Fellowship at Dalhousie University (Department of Biology), followed by a Banting Postdoctoral Fellowship at the University of Windsor (GLIER). She began as an Assistant Professor at the University of Connecticut in the Department of Natural Resources and the Environment, before returning to Canada to join 9I制作厂免费鈥檚 Department of Natural Resource Sciences to research environmental change and ecological stressors facing Arctic marine fish and mammals.

Current Research

Climate change ecology
Melting sea ice represents a key threat to the sustainability of Arctic marine mammals. Conversely, temperate and sub-Arctic marine mammals are redistributing northward to occupy these new areas of open water. Shifting community composition may lead to increased competition for food, as well as greater risk of predation, such as due to range-expanding killer whales. Yet, little is known about comparative feeding patterns among native and non-native marine mammals in the Arctic. We are using a multi-proxy, chemical tracers-based approach to determine changes in potential for competition and predation among species in a natural laboratory for climate change, the Arctic.听

Arctic marine pollution听
Chemical pollution is a major concern for the health of Arctic marine mammals and the people who harvest them for food, and climate change is impacting contaminant input into, and distribution within, northern ecosystems. We are evaluating, for example, how sea ice-driven changes in foraging habitat and behavior influence exposure to mercury, PCBs, PFAS, and other contaminants of concern for sensitive Arctic wildlife.听

Approaches to quantifying marine mammal diets听
The feeding habits of large marine mammals can have outsized impacts on food webs and may play a major role in food web restructuring with climate change. Yet, estimating the diets of species that live underwater in remote regions and that undergo large-scale movements remains a major challenge. We are developing and validating novel chemical tracer tools to quantify marine mammal diets. These tools include stable isotopes, fatty acids, and amino acid and fatty acid isotope analysis (known as compound-specific isotope analysis).

Stress ecology
The impacts of co-occurring environmental stressors on wildlife populations are rarely considered. Our work is showing that the pressing threats facing wildlife populations can no longer be studied in isolation and that climate change impacts and adaptation must be considered more holistically, in terms of connections to other global stressors, i.e., the triple planetary crisis of climate change, pollution, and biodiversity loss.
