Humans have dramatically increased atmospheric nitrogen (N) deposition globally. At the
coarsest resolution, N deposition is correlated with shifts from ectomycorrhizal (EcM) to …

Average nitrogen (N) deposition across Europe has declined since the 1990s. This resulted
in decreased N inputs to forest ecosystems especially in Central and Western Europe where …

Human activities have more than doubled reactive nitrogen (N) deposited in ecosystems,
perturbing the N cycle and considerably impacting plant, animal, and microbial communities …

Reactive nitrogen (N) deposition from intensive agricultural and industrial activity has been
identified as the third greatest threat to global terrestrial biodiversity, after land‐use and …

Although the influence of nitrogen (N) addition on grassland plant communities has been
widely studied, it is still unclear whether observed patterns and underlying mechanisms are …

Highlights•Carbon (C) responses to N inputs are derived from stoichiometric scaling, meta-
analysis of N addition experiments and field observations.•Hypotheses are presented on …

Abstract Background In 1994, a “Pan-European Programme for Intensive and Continuous
Monitoring of Forest Ecosystems” started to contribute to a better understanding of the …

Chronic nitrogen (N) deposition is a threat to biodiversity that results from the eutrophication
of ecosystems. We studied long‐term monitoring data from 28 forest sites with a total of …

Mediterranean Basin ecosystems, their unique biodiversity, and the key services they
provide are currently at risk due to air pollution and climate change, yet only a limited …

Human activities have greatly increased the reactive nitrogen in the biosphere, thus
profoundly altering global nitrogen cycling. The large increase in nitrogen deposition over …
