Headwater streams and wetlands are integral components of watersheds that are critical for
biodiversity, fisheries, ecosystem functions, natural resource‐based economies, and human …

Nitrous oxide (N2O) is a potent greenhouse gas that contributes to climate change and
stratospheric ozone destruction. Anthropogenic nitrogen (N) loading to river networks is a …

Rates of whole‐system metabolism (production and respiration) are fundamental indicators
of ecosystem structure and function. Although first‐order, proximal controls are well …

Estimates of global riverine nitrous oxide (N2O) emissions contain great uncertainty. We
conducted a meta‐analysis incorporating 169 observations from published literature to …

The importance of lotic systems as sinks for nitrogen inputs is well recognized. A fraction of
nitrogen in streamflow is removed to the atmosphere via denitrification with the remainder …

The number of anthropogenic compounds that occur in aquatic ecosystems today is in the
thousands, many at trace concentrations. One group of compounds that has captured the …

Abstract The Central Siberian Plateau is undergoing rapid climate change that has resulted
in increased frequency of forest fires and subsequent alteration of watershed carbon and …

Understanding global ecological patterns and processes, from biogeochemical to
