Abstract EN
Despite their crucial role in the nitrogen cycle, freshwater ecosystems are relatively rarely studied for active ammonia oxidizers (AO).
This study of Lake Lucerne determined the abundance of both amoA genes and gene transcripts of ammonia-oxidizing archaea (AOA) and bacteria (AOB) over a period of 16 months, shedding more light on the role of both AO in a deep, alpine lake environment.
At the surface, at 42 m water depth, and in the water layer immediately above the sediment, AOA generally outnumbered AOB.
However, in the surface water during summer stratification, when both AO were low in abundance, AOB were more numerous than AOA.
Temporal distribution patterns of AOA and AOB were comparable.
Higher abundances of amoA gene transcripts were observed at the onset and end of summer stratification.
In summer, archaeal amoA genes and transcripts correlated negatively with temperature and conductivity.
Concentrations of ammonium and oxygen did not vary enough to explain the amoA gene and transcript dynamics.
The observed herbivorous zooplankton may have caused a hidden flux of mineralized ammonium and a change in abundance of genes and transcripts.
At the surface, AO might have been repressed during summer stratification due to nutrient limitation caused by active phytoplankton.
