“…In the present study, three of the fifteen most abundant diazotrophic genera were significantly correlated with TP (Table 4). Among them, Desulfomonile has been reported to be more abundant at lower concentrations of total phosphorus in mangrove swamps in the North Beibu Gulf (China) (Li et al, 2022), which is consistent with our study. In addition, the diazotrophic phylum Nitrospirae was significantly and positively associated with TP in our study (Table 3).…”

“…Desulfuromonas has been previously reported to be significantly and positively associated with nitrogen densities in the saltmarshes soils within the Sydney Olympic Park (Australia) (Santini et al, 2019), which is similar to our data in the sediments of Poyang Lake. A previous study has shown that lower N levels may contribute to an increase in the amount of Desulfomonile in mangrove swamps in the North Beibu Gulf (China) (Li et al, 2022). FmdC, an outer-membrane porin in a Methylophilus strain, can be induced by short-chain amides and urea, and transport these nitrogen sources under conditions where they are present at very low concentration (Mills et al, 1997).…”

Water level fluctuations (WLFs) are typical characteristic of floodplain lakes and dominant forces regulating the structure and function of lacustrine ecosystems. The sediment diazotrophs play important roles in contributing bioavailable nitrogen to the aquatic environment. However, the relationship between the diazotrophic community and WLFs in floodplain lakes is unknown. In this paper, we carried out a comprehensive investigation on the alpha diversity, abundance, composition and co-occurrence network of the sediment diazotrophs during different water level phases in Poyang Lake. There were no regular variation patterns in the alpha diversity and abundance of the sediment diazotrophs with the water level phase transitions. The relative abundance of some diazotrophic phyla (including Alphaproteobacteria, Deltaproteobacteri, Euryarchaeota, and Firmicutes) and genera (including Geobacter, Deferrisoma, Desulfuromonas, Rivicola, Paraburkholderia, Methylophilus, Methanothrix, Methanobacterium, and Clostridium) was found to change with the water level phase transitions. The results of ANOSIM, PerMANOVA, and DCA at the OTU level showed that the diazotrophic community structure in the low water level phase was significantly different from that in the two high water level phases, while there was no significant difference between the two high water level phases. These results indicated that the diazotrophic community was affected by the declining water level in terms of the composition, while the rising water level contributed to the recoveries of the diazotrophic community. The diazotrophs co-occurrence network was disrupted by the declining water level, but it was strengthened by the rising water level. Moreover, redundancy analysis showed that the variation of the diazotrophic community composition was mostly related to sediment total nitrogen (TN) and total phosphorous (TP). Interestingly, the levels of sediment TN and TP were also found to vary with the water level phase transitions. Therefore, it might be speculated that the WLFs may influence the sediment TN and TP, and in turn influence the diazotrophic community composition. These data can contribute to broadening our understanding of the ecological impacts of WLFs and the nitrogen fixation process in floodplain lakes.
