Summary: This study assessed the microbiome diversity and cellulose decomposition processes on a 200-year-old ancient wooden seawall in Hangzhou, China. It found that the excavation of archaeological wood accelerates its deterioration process through carbohydrate metabolism and xenobiotic biodegradation pathways. Bacteroidetes, Proteobacteria, Firmicutes, and Actinobacteria were identified as the predominant sources of bacterial cellulose-decomposing enzymes.

Summary: Microbial community assembly is a complex process that determines community structure and function. This study investigated how external nutrient supply rate influenced interactions and therefore community assembly. The presence of algae strongly influenced community assembly, leading to convergence of initially diverse bacterial consortia. This study highlights the importance of understanding assembly processes in complex phototroph-heterotroph communities for global ecosystem functioning.

Summary: This study integrated river isotopes, 15N pairing experiments, and qPCR to reveal the processes driving the high NO3- levels in a nearly pristine forest river on the Qinghai-Tibet Plateau. The river isotopes suggested that, at the catchment scale, NO3- removal was prevalent in summer, but weak in winter. The release of soil NO3- to the river was transport-limited in both seasons, which resulted in the consistently high NO3- levels.

Summary: The study found that subsoiling in wheat-maize rotation fields in the Guanzhong area of Shaanxi Province helped increase water storage, organic carbon, and total nitrogen content in deep soil layers, improving soil nutrient status. However, subsoiling decreased soil bacterial richness and diversity compared to conventional tillage, but increased abundance of beneficial bacteria.

Summary: High nitrate levels in rivers can lead to eutrophication and have various ecological implications. This study investigated the drivers of high nitrate levels in a sparsely populated forest river and found that soil sources were a major contributor, with low removal processes. Nitrification was the dominant process in summer, while low temperature constrained nitrification in winter.

Summary: The metabolic potential and taxonomic composition of microbiota in sodic soils are influenced by salinity and alkalinity, with alkali vegetation types primarily determining catabolic profiles. The diversity and activity of microbial communities in the Pannonian steppe soils are more impacted by alkali vegetation types compared to extreme aridity and moisture conditions.

Summary: This study found that water temperature, rather than the presence of dams, is the main factor influencing the geographical distribution of bacterial communities in cascade reservoirs. There are significant spatial differences in sediment bacterial communities within a reservoir, potentially forming hotspots for biogeochemical cycling. Unlike in deep lakes and deep single reservoirs, the bacterioplankton community composition in deep cascade reservoirs does not have distinctly layered features due to density-induced underwater currents and convection.

Summary: Continuous cropping of Codonopsis tangshen resulted in a decline in both yield and quality, as well as a decrease in rhizospheric soil bacterial abundance and alteration of microbial community structure. Redundancy analysis indicated that organic matter content and available nitrogen content had the strongest impact on bacterial community structure in continuous cropping soil.

Summary: The study found that carbon amendment in greenhouse soils can significantly reduce nitrate leaching, increase nitrogen content in the subsoil, and enrich specific bacterial genera. Carbon amendment may achieve these effects by activating denitrifying and anaerobic bacterial populations.

Summary: A decrease in olive production in Tunisia since 2000 was attributed to climatic changes, wind erosion, and over cultivation. Studies on semi-arid soil properties revealed that soil tillage age was correlated with hydraulic conductivity, iron and organic matter content. Bacterial communities showed diversity, but farming techniques led to reduced diversity despite increased total bacterial biomass.

Summary: This study demonstrates that pH measurement can be used as the sole input for controlling the nitrate concentration in a phytoremediation tank. It also identifies a constant ratio between nitrate removal and acid dosing, which allows for the development of a nitrogen control strategy.

Summary: Our study investigated the diversity, community composition, and abundance of M. nitroreducens-like archaea in paddy soils, revealing significant impacts of soil depth and rice growth stage on their abundance. Soil organic carbon content and ammonium content were found to be key factors affecting the community structure of these archaea.

Summary: Understanding the process of methanogenesis in paddy fields under different elevated CO2 concentrations is crucial for reducing greenhouse gas emissions. In this study, we found that moderate increases in CO2 concentration can enhance methane flux in paddy fields. The abundance of methanogens is affected by CO2 concentration, with a significant decrease in relative abundance of uncultured genera under high CO2 concentrations.

Summary: The study revealed differential responses of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) communities to elevated CO2 in paddy ecosystems, with AOB showing greater sensitivity to the rising CO2 concentration. The abundance and nitrification potential of AOA and AOB in surface soils were significantly increased under elevated CO2. The variation in AOB abundance correlated well with the variation in nitrification potential, while the dynamics of AOB communities and nitrification potential were influenced by soil water content and dissolved organic carbon content.

Summary: Freshwater wetlands, paddy fields, inland aquatic ecosystems, and coastal wetlands are important sources of atmospheric methane. The anaerobic oxidation of methane (AOM) mediated by NC10 bacteria and ANME-2d archaea has been shown to play a crucial role in mitigating CH4 emissions. This review summarizes the different AOM processes and the functional microorganisms involved in these ecosystems, highlighting the significance of nitrite-dependent AOM and its relationship with soil/ sediment nitrogen and organic carbon contents. The study also highlights the potential of ANME-2d archaea in coupling AOM with the reduction of iron, manganese, sulfate, and humics.

Summary: By investigating four coastal wetlands in southeast China, we found that regional and local environmental conditions, as well as plant species cover, have an impact on nitrate-driven anaerobic oxidation of methane (AOM) activity and ANME-2d archaeal community. This study reveals the potential of this process in reducing methane emissions in wetlands and the influence of environmental factors.
