New paper from the Mojave examines a suite microbial responses to supplemental nitrogen in amounts similar to that deposited from urban air pollution. A meta-analysis is also included for similar studies in arid ecosystems. We were minor contributors to this nice paper, but it wouldn't have happened without the diligent and hard work of Travis and Aaron. Good job boys.
