Human-induced increase in nitrogen deposition profoundly alters nitrogen (N) cycling globally. Yet, the ultimate fate of nitrogen deposition on forest ecosystems isn’t fully understood. Rossella Guerrieri, a Marie Skłodowska-Curie fellow in CREAF sheds light on the overlooked leaf microbial transformations of nitrogen deposition and its contribution to N cycling.
Freshwater ecosystems near densely populated areas have levels of phosphorus which are very high and out of balance with nitrogen levels. This has resulted in altered ecosystem functioning, lower water quality, and has made water conservation more difficult.
