The effect of plant invasion on soil microbial carbon-use efficiency in semiarid grasslands of the Rocky Mountain West

Megan Nasto, Morgan McLeod, Lorinda Bullington, Ylva Lekberg & John Stark
1. Grassland ecosystems invaded by exotic plant species often exhibit substantially higher aboveground productivity and soil nitrogen (N) than the native communities they replace. These shifts are likely associated with altered microbial carbon (C) and N cycling, but we know surprisingly little about how these processes change with plant invasion. 2. Targeting four invasive plant species common in the Rocky Mountain West, we collected soils from invaded and adjacent uninvaded grassland field plots, as well...
