Bioavailable DOC: reactive nutrient ratios control heterotrophic nutrient assimilation—An experimental proof of the macronutrient-access hypothesis
Graeber, Daniel; Tenzin, Youngdoung; Stutter, Marc; Weigelhofer, Gabriele; Shatwell, Tom; von Tümpling, Wolf; Tittel, Jörg; Wachholz, Alexander; Borchardt, Dietrich (Biogeochemistry, 2021-06-08)We investigate the "macronutrient-access hypothesis", which states that the balance between stoichiometric macronutrient demand and accessible macronutrients controls nutrient assimilation by aquatic heterotrophs. Within ... -
Iron Exports From Catchments Are Constrained by Redox Status and Topography
Tittel, Jörg; Büttner, Olaf; Friese, Kurt; Lechtenfeld, Oliver J.; Schuth, Stephan; von Tümpling, Wolf; Musolff, Andreas (Global Biogeochemical Cycles, 2022-01-18)Fe(III) hydroxides stabilize organic carbon (OC) and P in soils. Observations of rising stream Fe concentrations are controversially posited to result from a flushing of iron‐rich deeper soil layers or a decrease of competing ...
