We are ecologists working to understand how global change alters plant communities and ecosystem processes. We work at focal research sites in Northern Canada and conduct data syntheses at tundra biome and global scales.
A key theme of our research is investigating climate change impacts in tundra ecosystems. There is strong evidence that tundra ecosystems are responding to a warming climate. However, we don’t yet know the mechanistic pathways leading to change that would allow for quantitative predictions. Vegetation change could restructure the tundra by influencing nutrient cycles, carbon storage, surface reflectance, thus creating feedbacks that can affect the planet as a whole. Our research group is addressing these major knowledge gaps to better understand the causes and consequences of vegetation change.
We conduct field research using a variety of tools including ecological monitoring, drones, dendroecology, decomposition experiments using tea bags, and more. We also lead data syntheses in collaboration with researchers working across the circumpolar Arctic and around the world.
We also really love shrubs.
