Anthropogenic nitrogen (N) and phosphorus (P) inputs have significant effects on plant community composition and diversity in forest ecosystems. Compared to canopy layers, understory communities are more sensitive to exogenous nutrient inputs. Although some experimental evidence exists on the effects of N addition on understory communities, knowledge about the impacts of P addition and its interaction with N, as well as the un...

Ecological stoichiometry in the plant–soil–microbial systems is crucial for regulating nutrient flow and sustaining ecosystem functions in forests. However, how rising atmospheric nitrogen (N) deposition induced by human activities impacts the stoichiometric relationships across ecosystem compartments remains poorly understood. We therefore conducted a 13‐year N‐addition experiment across eight forests from tropical to boreal...
