From Iron Curtain to green belt: shift from heterotrophic to autotrophic nitrogen retention in the Elbe River over 35 years of passive restoration [PDF]
BiogeosciencesWe investigate changes to in-stream nitrogen retention and metabolic processes in the Elbe River between 1978 and 2020. We analyzed multidecadal time series data and developed a metabolic nitrogen demand model to explain trends in dissolved inorganic ...
