AB  - Microbial processes such as nitrification and anaerobic ammonium oxidation 
      (anammox) are important for nitrogen cycling in marine sediments. Seasonal 
      variations of archaeal and bacterial ammonia oxidizers (AOA and AOB) and anammox 
      bacteria, as well as the environmental factors affecting these groups, are not 
      well studied. We have examined the seasonal and depth distribution of the 
      abundance and potential activity of these microbial groups in coastal marine 
      sediments of the southern North Sea. This was achieved by quantifying specific 
      intact polar lipids as well as the abundance and gene expression of their 16S 
      rRNA gene, the ammonia monooxygenase subunit A (amoA) gene of AOA and AOB, and 
      the hydrazine synthase (hzsA) gene of anammox bacteria. AOA, AOB, and anammox 
      bacteria were detected and transcriptionally active down to 12 cm sediment depth. 
      In all seasons, the abundance of AOA was higher compared to the AOB abundance 
      suggesting that AOA play a more dominant role in aerobic ammonia oxidation in 
      these sediments. Anammox bacteria were abundant and active even in oxygenated and 
      bioturbated parts of the sediment. The abundance of AOA and AOB was relatively 
      stable with depth and over the seasonal cycle, while anammox bacteria abundance 
      and transcriptional activity were highest in August. North Sea sediments thus 
      seem to provide a common, stable, ecological niche for AOA, AOB, and anammox 
      bacteria.
