TL;DR: In this article, the authors propose an approach that evaluates terrestrial sites based on whether they benefit or harm marine species or habitats, and then consider a hypothetical example involving estuarine nurseries.

TL;DR: In this article, the authors investigated the role of snowpack and soil nitrate in nitrogen export in high-elevation catchments of the Sierra Nevada using stable isotopes of nitrate and water, intensive monitoring of stream chemistry and detailed catchment N-budgets.

TL;DR: In this article, an in situ nitrate auto-analyzer on the moorings provided the first high-resolution time series of nitrate + nitrite (dissolved inorganic nitrogen, DIN) concentrations for this environment.

TL;DR: In this article, two-component hydrograph separations were performed for three nested, nested, snowmelt-dominated catchments in Sequoia National Park to differentiate between the old and new water contributions to discharge during snow-melt using δ18O signatures.

TL;DR: In this paper, the influence of physical (snow regime, runoff, and precipitation) and chemical (N loading) forcings on the observed variability in annual catchment yield and retention of N.
