The effect of experimental warming on the root-associated fungal community of Salix arctica
Abstract The effect of experimental warming on the root-associated fungal community of arctic willow (Salix arctica) was studied in three distinct habitats at a tundra site in the Canadian High Arctic. Plots were passively warmed for 5–7 years using open-top chambers and compared to control plots at...
