Deskripsi
The underlying regulatory mechanisms of phytoplankton assimilation and microbial oxidation of ammonium in the surface ocean are unclear. Here, using isotope labeling experiments, the authors show that ambient nitrate is a key variable bifurcating ammonium flow through assimilation or oxidation.
