Thaumarchaeota have been recognized as the main drivers of aerobic ammonia oxidation
in many ecosystems. However, little is known about the role of ammonia-oxidizing Archaea
(AOA) and Bacteria (AOB) in lacustrine ecosystems. In this study, the photic zone of three
contrasted freshwater ecosystems located in France was sampled during two periods: winter
homothermy (H) and summer thermal stratification (TS), to investigate the distribution of
planktonic AOA and AOB. We showed that AOB were predominant in nutrient-rich …
