Nitrate respiration and diel migration patterns of diatoms are linked in sediments underneath a microbial mat

Summary Diatoms are among the few eukaryotes known to store nitrate (NO 3 − ) and to use it as an electron acceptor for respiration in the absence of light and O 2 . Using microscopy and 15 N stable isotope incubations, we studied the relationship between dissimilatory nitrate/nitrite reduction to a... View More
