“…For instance, in the coastal wetlands of both the Yellow River Delta (China) and the northern Adriatic Sea (Italy), it has been emphasized that river input altered microbial structure patterns ( Fazi et al, 2020 ; Zhao et al, 2020 ). Thus, the results of this study are consistent with the environmental microbiomes that highlight associations between prokaryotic consortia, representing potential metabolic interactions with habitat transition ( Chaffron et al, 2010 ; Petro et al, 2017 ) and local heterogeneity that is usually characterized by highly productive systems.…”

Taxonomic and functional microbial communities may respond differently to anthropogenic coastal impacts, but ecological quality monitoring assessments using environmental DNA and RNA (eDNA/eRNA) in response to pollution are poorly understood. In the present study, we investigated the utility of the co-occurrence network approach’s to comprehensively explore both structure and potential functions of benthic marine microbial communities and their responses to Cu and Fe fractioning from two sediment deposition coastal zones of northern Chile via 16S rRNA gene metabarcoding. The results revealed substantial differences in the microbial communities, with the predominance of two distinct module hubs based on study zone. This indicates that habitat influences microbial co-occurrence networks. Indeed, the discriminant analysis allowed us to identify keystone taxa with significant differences in eDNA and eRNA comparison between sampled zones, revealing that Beggiatoaceae, Carnobacteriaceae, and Nitrosococcaceae were the primary representatives from Off Loa, whereas Enterobacteriaceae, Corynebacteriaceae, Latescibacteraceae, and Clostridiaceae were the families responsible for the observed changes in Mejillones Bay. The quantitative evidence from the multivariate analyses supports that the benthic microbial assemblages’ features were linked to specific environments associated with Cu and Fe fractions, mainly in the Bay. Furthermore, the predicted functional microbial structure suggested that transporters and DNA repair allow the communities to respond to metals and endure the interacting variable environmental factors like dissolved oxygen, temperature, and salinity. Moreover, some active taxa recovered are associated with anthropogenic impact, potentially harboring antibiotic resistance and other threats in the coastal zone. Overall, the method of scoping eRNA in parallel with eDNA applied here has the capacity to significantly enhance the spatial and functional understanding of real-time microbial assemblages and, in turn, would have the potential to increase the acuity of biomonitoring programs key to responding to immediate management needs for the marine environment.

“…Schwarz et al [ 41 ] found that the abundance and diversity of the archaeal community in Lake Kinneret sediments show relatively high little seasonal change, while Rodrigues et al [ 52 ] found that seasonal change had a significant impact on the richness and diversity of the archaeal community in Cerrado lake sediment. Previous studies on lakes and single reservoirs have shown that the diversity of archaeal communities is affected by sediment depth, sampling time, and geographical factors [ 23 , 48 , 53 , 54 ]. The study on the LRCR shows that the input of allochthonous organic carbon will significantly affect the diversity of the archaeal community in the sediments of the reservoir.…”

The spatial and temporal distribution of the archaeal community and its driving factors in the sediments of large-scale regulated rivers, especially in rivers with cascade hydropower development rivers, remain poorly understood. Quantitative PCR (qPCR) and Illumina MiSeq sequencing of the 16S rRNA archaeal gene were used to comprehensively investigate the spatiotemporal diversity and structure of archaeal community in the sediments of the Lancang River cascade reservoirs (LRCR). The archaeal abundance ranged from 5.11×104 to 1.03×106 16S rRNA gene copies per gram dry sediment and presented no temporal variation. The richness, diversity, and community structure of the archaeal community illustrated a drastic spatial change. Thaumarchaeota and Euryyarchaeota were the dominant archaeal phyla in the sediments of the cascade rivers, and Bathyarchaeota was also an advantage in the sediments. PICRUSt metabolic inference analysis revealed a growing number of genes associated with xenobiotic metabolism and carbon and nitrogen metabolism in downstream reservoirs, indicating that anthropogenic pollution discharges might act as the dominant selective force to alter the archaeal communities. Nitrate and C/N ratio were found to play important roles in the formation of the archaeal community composition. In addition, the sediment archaeal community structure was also closely related to the age of the cascade reservoir and hydraulic retention time (HRT). This finding indicates that the engineering factors of the reservoir might be the greatest contributor to the archaeal community structure in the LRCR.

“…Coastal wetlands are predominately controlled by water and salinity due to tides and underground seawater (Ma et al, 2017;. The restrained plant productivity leads to low SOM (Zhao et al, 2020), decreasing the accumulation of microbial AS. Also, plant phenology shows a quick response to changed soil salinity (Sun et al, 2021).…”

“…Soil microorganisms are key participants and drivers in SOC transformation, formation, and storage through microbial metabolic processes (Trivedi et al, 2013;Spivak et al, 2019). Microbial community composition (e.g., fungi and bacteria) and extracellular enzymes govern litter decomposition, soil nutrient release, and recycling, which further influence SOC turnover in coastal wetlands (Hill et al, 2018;Zhao et al, 2020). However, it is not clear how microbes directly contribute to SOC accumulation through microbial metabolites (e.g., microbial necromass) in coastal wetlands.…”

Salinity Effects on Microbial Derived-C of Coastal Wetland Soils in the Yellow River Delta

Microorganisms play a crucial role in regulating the turnover and transformation of soil organic carbon (SOC), whereas microbial contribution to SOC formation and storage is still unclear in coastal wetlands. In this study, we collected topsoil (0–20 cm) with 7 salinity concentrations and explored the shifts in microbial residues [represented by amino sugar (AS)] and their contribution to the SOC pool of coastal wetlands in the Yellow River delta. The gradually increasing soil salinity reduced soil water content (SWC), SOC, and soil nitrogen (N), especially in high salinity soils of coastal wetlands. Total ASs and their ratio to SOC, respectively, decreased by 90.56 and 66.35% from low salinity to high salinity soils, indicating that coastal wetlands with high salinity restrained microbial residue accumulation and microbial residue-C retention in the SOC pool. Together with redundancy analysis and path analysis, we found that SWC, pH, SOC, soil N, and glucosamine/muramic arid were positively associated with the ratio of ASs to SOC. The higher available soil resource (i.e., water, C substrate, and nutrient) increased microbial residue accumulation, promoting microbial derived-C contribution to SOC in low salinity coastal wetlands. The greatly decreased microbial residue contribution to SOC might be ascribed to microbial stress strategy and low available C substrate in coastal wetlands with high salinity concentration. Additionally, the gradually increasing salinity reduced fungal residue contribution to SOC but did not change bacterial residue contribution to SOC. These findings indicated that changed fungal residues would substantially influence SOC storage. Our study elucidates microbial contribution to SOC pool through residue reservoir in coastal wetlands and pushes microbial metabolites to a new application in global wetland SOC cycling.
