Revealing the Drivers of Unexpected High Nitrogen Levels in Tropical Rainforest Rivers in Winter

Ecosystem Health and Sustainability
Elevated river nitrogen (N) concentrations have contributed to eutrophication and subsequent ecological damage worldwide. However, current research has mostly focused on nitrate (NO3−) in rivers, with relatively few studies on the sources of different N ...
