Summary: The soil microbiome is affected by both bottom-up and top-down processes at the local soil aggregate level. Predation plays an important role in shaping the diversity and stability of soil bacterial communities, with a greater impact on macroaggregates. Predation also alters the abundance of microbial genes associated with carbon and nitrogen metabolisms.

Summary: This study investigated the diversity and assembly mechanisms of soil bacterial and fungal communities in four ecoregions of Shaanxi Province, China. The results showed that microbial community composition was influenced by soil pH, nutrients, and mean annual precipitation. Bacterial community assembly was mainly driven by variable selection, while fungal community assembly was influenced by both variable selection and stochastic processes.

Summary: The study found that soil pH can predict bacterial diversity, with variations in community composition, diversity, assembly, and gene abundance across different soil pH gradients. Alphaproteobacteria and Acidobacteria were more common in acidic soils, with peak richness and diversity at intermediate pH values. Soil pH also influenced gene selection in bacterial communities.

Summary: This study investigates the changes in diversity of soil bacterial communities and the effects of these communities on enzymes in soil polluted by Cr(VI). The results show that chromium content in polluted soils is higher than in control soils, and that pollutants affect the composition and diversity of the bacterial community. The findings provide insights into the ecotoxicological effects of Cr(VI) exposure on soil microorganisms and are critical for evaluating the state of microbial community structures and the potential risk of metal accumulation in soils.

Summary: The research showed that grazing exclusion has minimal impact on soil bacterial alpha-diversity, while soil bacterial community composition is significantly influenced by soil chemical properties. The higher plant community alpha-diversity and soil nutrition in alpine shrublands did not result in higher soil bacterial alpha-diversity.

Summary: This study investigated the composition and putative functions of endophytic bacterial communities in ungerminated and germinated seeds of commercial vegetables. The results revealed a high variability in the abundance, diversity, composition, and functionality of endophytic bacteria between ungerminated and germinated seeds in globally commercialized vegetables.

Summary: This on-farm study investigates the effects of no-till agricultural diversification and intensification of crop rotations (DICR) on soil biological properties. The results show that DICR can alter the composition of soil microbiota, which can contribute to the design of more sustainable agricultural systems.

Summary: Fumigants and non-fumigants used in strawberry production have different effects on nematode and weed control, as well as on soil microbial diversity. Fumigants can alter soil microbial community composition and functionality, while both fumigants and non-fumigants reduce soil bacterial and fungal diversity.

Summary: This study investigates the impact of precipitation changes on species diversity and soil properties in the Artemisia ordosica community. The results show that variations in precipitation amount and intervals can alter the species diversity of the community. Increased precipitation improves species diversity by enhancing the richness of perennial forbs, while lengthened precipitation intervals decrease species diversity. The precipitation patterns affect species composition and diversity mainly through controlling soil moisture and changing soil nitrogen and organic matter content.

Summary: This study compared the effects of biochar and hydroxyapatite on soil bacterial communities in a slightly Cd-contaminated farmland grown with sweet sorghum of different planting densities. The results showed that both biochar and hydroxyapatite decreased the diversity and richness of soil bacteria, but they had different effects on bacterial community structure. These findings contribute to a better understanding of the ecological impacts of soil remediation agents.

Summary: Our study is the first exploration of the microbiome in the soil of the Sumaco stratovolcano and examines the effects of an elevational gradient and soil parameters on microbial richness and community structure. We found that sulfur, rather than pH or altitude, played a significant role in bacterial community structure. Additionally, metallic cations and CEC were positively correlated with richness.

Summary: Natural selection is the major force driving adaptive evolution in Mediterranean ecosystems, but the patterns of selection at the intraspecific level are largely unknown. Studying two Mediterranean endemic species, researchers found that reproductive fitness consistently favored a strategy of drought-escape and resource acquisition.

Summary: The changes in PSII photochemical processes in Antarctic algae cells exposed to salinity stress were studied. The study found that salinity stress leads to a decrease in the potential and effective quantum yield of PSII electron transport. The vitality index of chlorophyll fluorescence also decreases under salinity stress. The analysis revealed that with increasing salt concentration, the chlorophyll fluorescence signals weaken, and the transient response becomes flattened, approaching zero values at a salt concentration of 3M NaCl. Klebsormidium sp. was found to be more resistant to salinity stress compared to Stigeoclonium sp.

Summary: The productivity of ethanol in microbial electrosynthesis (MES) cells can be enhanced by optimizing operation parameters. Strict conditions, including low pH and pCO2, high HA concentration, and high pH2, are necessary for efficient solventogenic culture. Future research should focus on improving cell configuration for higher ethanol production at lower electric energy input.

Summary: Recently, it has been suggested that Alcaligenes can convert ammonium into dinitrogen gas using a previously unknown pathway. This research found that Alcaligenes can simultaneously oxidize succinate and ammonium in the presence of a polarised electrode and without aeration. This indicates that the polarised electrode can support the metabolic functions of Alcaligenes.
