Ammonia oxidation carried out by ammonia-oxidizing microorganisms (AOMs) is a central
step in the global nitrogen cycle. Aerobic AOMs comprise conventional ammonia-oxidizing …

Isoprenoidal glycerol dialkyl glycerol tetraether (isoGDGT) lipids occur ubiquitously in
freshwater and marine environments. Since their distribution varies with temperature …

Marine Archaea are important players among microbial plankton and significantly contribute
to biogeochemical cycles, but details regarding their community structure and long-term …

Summary The Laurentian Great Lakes are a vast, interconnected freshwater system
spanning strong physicochemical gradients, thus constituting a powerful natural laboratory …

Niche specialization of nitrifying prokaryotes is usually studied with tools targeting molecules
involved in the oxidation of ammonia and nitrite. The ecological significance of diverse CO2 …

Deep oligotrophic lakes sustain large populations of the class Nitrososphaeria
(Thaumarchaeota) in their hypolimnion. They are thought to be the key ammonia oxidizers in …

Ammonia released during organic matter mineralization is converted during nitrification to
nitrate. We followed spatiotemporal dynamics of the nitrifying microbial community in deep …

Despite their key role in biogeochemical processes, particularly the methane cycle, archaea
are widely underrepresented in molecular surveys because of their lower abundance …

While mechanisms of different carbon dioxide (CO2) assimilation pathways in
chemolithoautotrohic prokaryotes are well understood for many isolates under laboratory …

Urban lakes play an important role in urban residents' lives, but they are more vulnerable to
nitrogen pollution due to the large number of pollution sources in urban areas. Analyzing the …
