N2 - We evaluated ectomycorrhizal (ECM) colonization and morphotype community composition together with growth response and biomass distribution in the arctic-alpine, prostrate willow Salix herbacea L. x Salix polaris Wahlenb. after 11 seasons of shading, warming, and fertilization at a fellfield in subarctic Sweden. The aim was to assess responses of the integrated plant-fungal system to long-term field experiments simulating expected environmental changes. Warming more than doubled aboveground S. herbacea x S. polaris biomass and shoot growth, whereas shading and nutrient addition had less influence on these variables. In shaded plants, adjustments at leaf level ...
