Different seasonality of pelagic and benthic Thaumarchaeota in the North Sea
We have examined the spatial and seasonal distribution of Thaumarchaeota in the water column and sediment of the southern North Sea using the specific intact polar lipid (IPL) hexose-phosphohexose (HPH) crenarchaeol, as well as thaumarchaeotal 16S rRNA gene abundances and expression. In the water co...

| description | We have examined the spatial and seasonal distribution of Thaumarchaeota in
the water column and sediment of the southern North Sea using the specific
intact polar lipid (IPL) hexose-phosphohexose (HPH) crenarchaeol, as well as
thaumarchaeotal 16S rRNA gene abundances and expression. In the water
column, a higher abundance of Thaumarchaeota was observed in the winter
season than in the summer, which is in agreement with previous studies, but
this was not the case in the sediment where Thaumarchaeota were most
abundant in spring and summer. This observation corresponds well with the
idea that ammonia availability is a key factor in thaumarchaeotal niche
determination. In the surface waters of the southern North Sea, we observed
a spatial variability in HPH crenarchaeol, thaumarchaeotal 16S rRNA gene
abundance and transcriptional activity that corresponded well with the
different water masses present. In bottom waters, a clear differentiation
based on water masses was not observed; instead, we suggest that observed
differences in thaumarchaeotal abundance with depth may be related to
resuspension from the sediment. This could be due to suspension of benthic
Thaumarchaeota to the water column or due to delivery of e.g. resuspended
sediment or ammonium to the water column, which could be utilized by pelagic
Thaumarchaeota. This study has shown that the seasonality of Thaumarchaeota
in water and sediment is different and highlights the importance of water
masses, currents and sedimentary processes in determining the spatial
abundance of Thaumarchaeota in the southern North Sea. |
