Historical increases in emissions and atmospheric deposition of oxidized and reduced
nitrogen (N) provided the impetus for extensive, global-scale research investigating the …

Tropical primary forests have been disappearing quickly to make use of the land for
commercial purposes. Land-use change has an impact on downstream aquatic processes …

Water security is a top concern for social well-being, and dramatic changes in the availability
of freshwater have occurred as a result of human uses and landscape management …

Dissolved organic carbon (DOC) and nitrogen (DON) are important energy and nutrient
sources for aquatic ecosystems. In many northern temperate, freshwater systems DOC has …

We evaluated long-term surface water nitrate and atmospheric nitrogen (N) deposition
trends for a group of nine predominantly forested Appalachian Mountain watersheds during …

Human activity has significantly increased the deposition of nitrogen (N) on terrestrial
ecosystems over pre‐industrial levels leading to a multitude of effects including losses of …

A comprehensive cross‐biome assessment of major nitrogen (N) species that includes
dissolved organic N (DON) is central to understanding interactions between inorganic …

Abstract Across the conterminous United States (US), the composition of atmospheric
nitrogen (N) deposition is changing spatially and temporally. Previously, deposition was …

Patterns of watershed nitrogen (N) retention and loss are shaped by how watershed
biogeochemical processes retain, biogeochemically transform, and lose incoming …

The ecological state of the Baltic Sea and the inland waters has raised interest in reducing
nutrient loads from anthropogenic sources. In this study our main aim was to estimate the …
