“…This suggests that these phyla may be related to the uptake of Na + by the root system in rhizosphere soil, which contributed to improving the resistance of plants to drought and high salt stress [40,59]. Soil EC was a major factor affecting the structure and distribution of soil bacterial community in many studies [60]. It has an impact on many dominant phyla, especially Firmicutes and Proteobacteria, which was consistent with the findings of other studies [61,62].…”

Understanding the response of soil properties and bacterial communities in rhizosphere soil to aridity and dune types is fundamental to desertification control. This study investigated soil properties and bacterial communities of both rhizosphere and bulk soils of Caragana microphylla from four sites with different aridity indices, and one site with three different types of dunes. All sites were located in the desert regions of northern China. The results indicated that compared with the bulk soil, the soil nutrient content of rhizosphere, especially the content of total phosphorus, was generally significantly improved in different desertification environments. The bacterial richness and diversity were also higher than those of bulk soil, especially in arid regions and fixed dunes. Firmicutes, Actinobacteria, Proteobacteria, and Acidobacteria were the most dominant phyla in all samples. The regression analyses showed that at different sites, soil total organic C, total N, Na+, and total P played key roles in determining the bacterial community structure while total organic carbon, electronic conductivity, pH and total phosphorus were the dominant factors at the different dunes. The results further revealed that the dominant phyla strongly affected by environmental factors at different sites were Acidobacteria, Gemmatimonadetes, and Actinobacteria among which, Acidobacteria and Gemmatimonadetes were negatively correlated with Na+ content. At different types of dunes, Actinobacteria, Planctomycetes, and Gemmatimonadetes were particularly affected by environmental factors. The increased abundance of Actinobacteria in the rhizosphere soil was mainly caused by the decreased soil pH.

“…The study on bacterial community in the rearing water of Pacific white shrimp showed that the OTUs were in the range of 88-234, Shannon diversity indices were 2.05-3.90, and Chao 1 indices ranged from 107 to 350 (Zheng et al, 2017). Hua et al (2017) investigated the bacterial community with different coastal reclamation histories in Jiangsu Province (Eastern China) to find that the Shannon indices and Chao 1 indices were in the ranges of 8-10 and 2000-20,000, respectively. All studies indicated that the bacterial diversity levels in the intensive fish farms were lower than those in other reclamation coastal ecosystems.…”

“…The high-throughput sequencing method based on 16S rDNA amplicon sequencing technology can make an in-depth analysis on the bacteria community and abundance (Leite et al, 2012). The amplicon sequencing approach has been widely used to characterize the microbial communities and abundances in various environments such as rivers (Zhou et al, 2017), aquaculture environment (Zheng et al, 2017), and soil (Hua et al, 2017).…”

The conventional and recirculating mariculture systems are two typical intensive mariculture systems in the coastal zone. This study used high-throughput sequencing method to investigate the structural profiles of microbial communities in conventional and recirculating mariculture farms. The results showed that 13,842 OTUs (operational taxonomic units) were detected at a similarity level of 97%. Conventional and recirculating systems exhibited significant difference in microbialcommunity based on the results of the taxonomy and relative abundance of bacteria. Among the top 10 genera in coastal intensive mariculture systems, the predominant bacteria in the conventional intensive mariculture system were Pseudofulvibacter, Polaribacter, Glaciecola, Crocinitomix, Colwellia, Oleispira, and Balneola, while those in the recirculating systems were Vibrio, Alteromonas, and Pseudoalteromonas. Bacterial communities of different fish ponds suggested that the bacterial groups exhibited fish-specific or water treatment stage-specific features. Potential pathogens such as Vibrio, Arcobacter, Pseudoalteromonas, and Shewanella were readily accumulated as dominant bacteria in the recirculating mariculture system. The detection of similar potential pathogens in both the mariculture systems and the adjacent coastal water indicate that the mariculture farms without recirculating system could be the hotspots of pathogens and have great influences on the surrounding coastal environment. The wastewater treatment units used in recirculating farm could remove bacteria effectively, suggesting that the recirculating mariculture system may be more environmentally friendly than the conventional mariculture system.

“…Soil microorganisms are an important driving force for mediating and sustaining soil processes (Rashid et al, 2016) and play important roles in nutrient cycling and stability of ecosystems (Hua, Feng, Jiang, Bao, & Yin, 2017). Significant changes in microbial community composition and functionality have been observed after wetland conversion (Ding, Su, Li, Zhu, & Cao, 2017), including the conversion from natural wetlands to grasslands or forests (Berthrong, Schadt, Piñeiro, & Jackson, 2009), from estuary marsh wetland to paddy rice and upland crop fields (Cui, Liu, et al, 2012; Cui, Meng, et al, 2012), and from natural wetland to various land use types (Huang et al, 2019).…”

The reclamation and utilization of natural wetlands can affect the community structure of soil microorganisms. However, knowledge regarding succession of microbial communities during long‐term reclamation and the links with related nutrient cycles is still limited. Using Illumina sequencing, we identified the patterns and environmental drivers of soil bacterial and fungal succession along a 150‐year chronosequence of paddy fields. Soil enzyme activities were determined to characterize functions related to C, N, and P cycles. The results showed that reclamation activity and its history have greatly altered the bacterial community structure and the bacterial groups. This change being mainly reflected in the bacterial genera Halomonas, genera Isosphaera, and family Planctomycetaceae. The change of fungal community was mainly apparent between natural wetlands and paddy fields, manifested as an increase in the classes Sordariomycetes and Dothideomycetes and a significant decrease inthe class Agaricomycetes in paddy fields compared with natural wetland. Compared with fungi, bacteria were more strongly affected by soil chemical nutrient properties and physical properties. Furthermore, the structural equation model indicated that both bacterial and fungal community structure and diversity had a great influence on the C, N, and P cycles. In summary, the bacterial community was more sensitive throughout the history of rice cultivation after reclamation than the fungal community, but both bacteria and fungi may play major roles in soil ecological functions. These findings contribute to the understanding of ecosystem functional mechanisms, which provides a new perspective for the management of natural wetlands.
