Field observations and experimental data of effects of nitrogen (N) deposition on plant
species diversity have been used to derive empirical critical N loads for various ecosystems …

Are current estimates of silicate minerals weathering rates precise enough to predict
whether nutrient pools will recover after forest harvesting? Answering this question seems …

Acid deposition is formed from SO2 and NOx emitted to the atmosphere, largely because of
fossil-fuel combustion. The most important sources are energy production, especially coal …

Together with habitat conversion and climate change, the atmospheric deposition of reactive
nitrogen (abbreviated Nr or N) has been recognised as one of the most important threats to …

Temporal trends in DOC concentration and flux were investigated at two geochemically
distinct forested catchments in western Czech Republic. Mean discharge-weighted DOC …

Lake acidification became an environmental issue of international significance in the late
1960s and early 1970s when Scandinavian scientists claimed that “acid rain” was the …

Biodiversity has been described as the diversity of life on earth within species, among
species, and among ecosystems. The rate of biodiversity loss due to human activity in the …

Several biotic crises during the past 300 million years have been linked to episodes of
continental flood basalt volcanism, and in particular to the release of massive quantities of …

Long-term records of nitrogen in deposition and streamwater were analysed at 30 sites
covering major acid sensitive regions in Europe. Large regions of Europe have received …

Regional-scale databases can be particularly useful for identifying relationships between
dissolved inorganic nitrogen (N) leaching in forests and environmental drivers, which in turn …
