Tight coupling of surface water diel dissolved oxygen (DO) and nitrate-N (NO3-N) signals reflects stoichiometric demand of carbon and nitrogen in stream ecosystems. However, DO and NO3-N can become decoupled due to alternative drivers of diel solutes, resulting in conflicting estimates of stoichiometric and modeled NO3-N uptake. In this study, I measured benthic biomass, hydrology, and dissolved solutes in a montane stream located in western MT over a growing season (June-October 2019). Daily stream metabolism and NO3-N uptake were modeled using a single-station open-channel approach. Timing and amplitude of key diel signals …
