Dr. Jill F. Johnstone


Dr. Jill Johnstone is currently a professor in the Department of Biology, University of Saskatchewan (Canada) where she conducts research in plant ecology and environmental biology. Much of her research focuses on northern ecosystems, such as boreal forest and tundra, that are currently experiencing rapid rates of climate change. She uses field measurements and experimentation combined with statistical or simulation modeling to examine the dynamics of plant community responses to environmental change. She is particularly interested in how disturbances may catalyze ecosystem changes and the role of plant-soil interactions in stabilizing different potential configurations of ecosystems. She has been at the University of Saskatchewan since 2006, where she has taught undergraduate and graduate courses in community ecology, environmental biology, and biostatistics. Her current research focuses on forest and tundra dynamics in mountainous regions of Alaska and Yukon, as well as flatter landscapes in northern Saskatchewan and NWT.
