Human activity has significantly increased the deposition of nitrogen (N) on terrestrial
ecosystems over pre‐industrial levels leading to a multitude of effects including losses of …

Atmospheric deposition of nitrogen (N) and sulfur (S) has increased dramatically over pre‐
industrial levels, with many potential impacts on terrestrial and aquatic ecosystems …

Critical loads of atmospheric deposition help decision-makers identify levels of air pollution
harmful to ecosystem components. But when critical loads are exceeded, how can the …

Nitrogen (N) loading to aquatic ecosystems can lead to eutrophication, changing the
ecosystem within a waterbody, including primary productivity, water clarity, and food web …

Anthropogenic stressors such as climate change, increased fire frequency, and pollution
drive shifts in ecosystem function and resilience. Scientists generally rely on biological …

Often termed “acid rain,” combined nitrogen and sulfur deposition can directly and indirectly
impact the condition and health of forest ecosystems. Researchers use critical loads (CL s) …

Increases in anthropogenic emissions of sulfur (S) and nitrogen (N) have resulted in
increases in the associated atmospheric deposition of acidic compounds. In sensitive …

Abstract The North American Nitrogen Center (NANC) carries out three main charges:(1)
conducting assessments on nitrogen (N) flows within North America and the consequences …

Abstract Bellingham Bay and the Nooksack River Basin will provide the test case for an
international nitrogen (N) management system for North America. Spanning a portion of the …
