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...

Anthropogenic nitrogen (N) inputs can significantly impact nutrient cycling and ecosystem functioning in terrestrial ecosystems. However, the effects of N addition on phosphorus (P) cycling processes in forest ecosystems remain unclear. In this study, we combined data from a long‐term (11‐year) N addition experiment across seven different forests ranging from temperate to tropical biomes, with a global meta‐analysis from 88 re...

Mycorrhizal associations drive plant community diversity and ecosystem functions. Arbuscular mycorrhiza (AM) and ectomycorrhiza (EcM) are two widespread mycorrhizal types and are thought to differentially affect plant diversity and productivity by nutrient acquisition and plant–soil feedback. However, it remains unclear how the mixture of two mycorrhizal types influences tree diversity, forest biomass, and their relationship a...
