Research Scientist, Arctic Ecosystems and Biotracers

Lisa conducts research that focuses on characterizing beluga health as means to understand ecosystem health in the Western Canadian Arctic. She combines food web biotracers and habitat modeling to gain insight into predator-prey interactions and ecosystem energetics. Her research on beluga diet and habitat use combines Western science and traditional ecological knowledge (TEK). Her research programs are carried out in partnership with communities and co-management boards of the Inuvialuit Settlement Region. She strives to serve all Canadians by providing knowledge and advice to decision makers and by helping to empower the people of the north through scientific knowledge combined with their own knowledge of their ecosystem and home.   

Current research and/or projects

Dr. Lisa Loseto is a Research Scientist at Fisheries and Oceans Canada in Winnipeg with the Arctic Aquatic Research Division. Her research focuses on characterizing beluga health to better understand ecosystem health in the Western Canadian Arctic. Working closely with the Inuit communities of the Western Arctic, the Inuvialuit, she works to better understand beluga diet, habitat use and climate change impacts combining both western science and traditional ecological knowledge.
