Concepts

Human-induced nitrogen input that has doubled biologically-available nitrogen on Earth

Spatial variability in biogeochemical processes and solute sources within watersheds, particularly between shallow soil zones and deeper groundwater zones

Ability of forest ecosystems to maintain function during water-limited conditions through adaptive water use strategies

The relationship between solute concentrations and discharge in streams, widely used as a metric for interpreting interaction of hydrological processes, chemical transport, and mineral reactions in wa...

Redox-stratified and temporally dynamic sediments in river corridors where biological processes mediate sulfur transformations

Concentration-discharge pattern where solute concentrations remain relatively constant across flow conditions, indicated by C-Q slope near zero

Spatial variations in oxidation-reduction conditions within floodplain environments that can form within microsites, along textural transitions, or along the capillary fringe
