The solution chemistry of forested streams primarily in western North America is explained
by considering the major factors that influence this chemistry—geological weathering; …

We review known and hypothesized effects of nitrogen (N) deposition owing to human
activities on the chemistry, organisms, and ecosystem processes of remote oligotrophic …

Highly resolved time series data are useful to accurately identify the timing, rate, and
magnitude of solute transport in streams during hydrologically dynamic periods such as …

The depth and duration of snow pack is declining in the northeastern United States as a
result of warming air temperatures. Since snow insulates soil, a decreased snow pack can …

We explored catchment processes that control stream nutrient concentrations at an upland
forest in northeastern Vermont, USA, where inputs of nitrogen via atmospheric deposition …

To assess the concern over declining base cation levels in forest soils caused by acid
deposition, input-output budgets (1990s average) for sulphate (SO 4), inorganic nitrogen …

The nitrogen (N) emissions to the atmosphere and N deposition to forest ecosystems are
increasing rapidly in Southeast Asia, but little is known about the fates and effects of …

We present long‐term changes in Norwegian lake water quality across regional gradients in
atmospheric pollution, air temperature, hydrology, and vegetation using (a) a national …

We sampled the understory community in an old‐growth, temperate forest to test alternative
hypotheses explaining the establishment of exotic plants. We quantified the individual and …

Nitrate (NO 3−) contamination of groundwater associated with agronomic activity is of major
concern in many countries. Where agriculture, thin free draining soils and karst aquifers …
