Carbon dioxide is the main greenhouse gas inducing climate change. Increased global CO2 emissions, estimated at 8.4 Pg C yr−1 at present, have accelerated from 1% yr−1during 1990–1999 to 2.5% yr−1 during 2000–2009 (ref. 1). The carbon balance of terrestrial ecosystems is the greatest unknown in the global C budget because […]

Invasive plants like cheatgrass have huge and costly effects on ecosystems. Restoring native plants to areas invaded by cheatgrass is challenging, and one explanation for poor seedling establishment is the absence of beneficial soil microbes. In this project, we are testing the idea that restoring microbial communities promotes ecosystem recovery and the re-establishment of native plants.
