“…Archaea diversity increased with soil salinity, with their number of OTU showing robust positive correlation with EC e . This trend is in agreement with the one reported by Wei et al (2020) for Chinese soils under monsoon climate. Archaea are abundantly found in desert saline soils, and their diversity is usually dominated by the orders Halobacteriales, Haloferacales, and Natrialbales (Bachran et al 2019).…”

Smart Capillary Barrier (SCB) has been recently promoted to decrease soil salinity and improve water use efficiency and the sustainability of arid land agriculture. In this study, we investigated the effect of SCB on soil microbial diversity, enumeration, and respiration in a tomato field trial. SCB soil and control (unstructured homogenous soils, H) plots were irrigated with four levels of salinity (EC w = 0.8, 3, 6, and 9 dS m −1). Microbial diversity was assessed by ITS and 16S rRNA gene sequencing, enumeration of culturable heterotrophs by agar plates, and microbial respiration by MicroResp™ assays. Salinity was the main driver of the soil microbial diversity, showing a substantial reduction in the number of operational taxonomic units (− 8% for both bacteria and fungi), enumeration of culturable heterotrophs (− 51% for bacteria and − 53% for fungi), and respiration (− 18%) at 9 dS m −1 water salinity. Microbial community composition was significantly different between the SCB and H soils, as evidenced by multivariate analyses and by the appearance of 3352 unique operational taxonomic units at SCB samples that were absent in H plots. The SCB soil showed a steeper metabolic quotient increase in response to soil salinity than the H soils. The abundance of functional microbes such as nitrogen-fixing and nitrifying prokaryotes, as well as mycorrhiza, was also significantly increased in the SCB soils in comparison with the H soils. Our findings suggest that adopting SCB design leads to higher overall soil microbial biodiversity, including those communities unable to withstand extreme soil salinity conditions.

Fertilizer-induced changes in soil nutrients regulate nitrogen (N) fixation in the terrestrial biosphere, but the influences of N and phosphorus (P) fertilization on the diazotroph communities in successive crop seasons were unclear. In this study, we assessed the effects of N and P (high vs. low doses) on the abundance and structure of N2-fixation communities after wheat and soybean harvest in a long-term (34 and 35 years) fertilization experiment. In both seasons, long-term N addition significantly decreased the abundance of nifH genes and 16S rDNA; in addition, high doses of N and P fertilizer decreased the richness of diazotrophs, whereas low doses did not. The proportion of the dominant genus, Bradyrhizobium, in the soybean season (86.0%) was higher than that in the wheat season (47.9%). Fertilization decreased diazotroph diversity and the relative abundance of Bradyrhizobium in the wheat season, but had insignificant effects in the soybean season. The addition of N, but not P, significantly changed the communities of both diazotrophs (at the genus level) and rhizobia (at the species level) in the two seasons. Soil pH was positively associated with nifH abundance and diazotrophic richness; soil NO3− content was negatively correlated with diazotrophic richness and positively correlated with diversity. Soil pH and NO3− content were the two main drivers shaping the soil diazotrophic community. Overall, long-term inorganic N had a greater influence than P on both diazotrophic abundance and community composition, and diazotrophic diversity was more clearly affected by fertilization in the wheat season than in the soybean season.

“…For example, Wei and colleagues compared the archaeal and bacterial community features in bulk soils under different vegetation covers and found that similar edaphic factors showed nearly opposite effects to the two domains. Their study also supported that archaea showed more niche limitation and less widely distributed than bacteria [34].…”

“…For example, a study conducted in Chinese marginal seas surface sediment found that benthic bacteria were numerically dominant relative to archaea [33], which supported our nding. Furthermore, previous study reported that the dynamics of distinct microbial groups were constrained by different environmental variables [34].

Background: Mangrove ecosystems are vulnerable due to the exotic Spartina alterniflora invasion in China. Large knowledge gaps remain with regard to archaeal and bacterial communities assembly processes and microbial interactions under S. alterniflora invasion. Here, using 16S rRNA gene amplicon sequencing, we investigated the assembly processes and co-occurrence relationships of the archaeal and bacterial communities under S. alterniflora invasion along the coastlines of Fujian province, southeast China.Results: We found that the overall archaeal and bacterial communities were driven predominantly by stochastic processes, and the relative role of stochasticity was stronger for bacteria than archaea. Co-occurrence network analysis showed that the network structure of bacteria was more complex than that of the archaea. Putative keystone taxa often had low relative abundances (conditionally rare taxa), suggesting conditionally rare taxa or low abundances taxa may significantly contribute to network stability. Moreover, we found that S. alterniflora invasion changed the microbial communities assembly and co-occurrence patterns, indicating that S. alterniflora affected the composition and stability of the microbial community.Conclusions: This study provides the first comparison in the biogeography and co-occurrence patterns of both archaea and bacteria in mangrove ecosystem. And this is the first exploration about the effect of S. alterniflora invasion on archaeal and bacterial ecological processes and co-occurrence patterns. Our study considers that the control of S. alterniflora invasion is important for mangrove ecosystem function and service.
