Invasive Plants Rapidly Reshape Soil Properties in a Grassland Ecosystem

ABSTRACT Plant invasions often reduce native plant diversity and increase net primary productivity. Invaded soils appear to differ from surrounding soils in ways that impede restoration of diverse native plant communities. We hypothesize that invader-mediated shifts in edaphic properties reproducibl...
