Summary: This study analyzed the changes in soil microbial community diversity after five years of restoration in an alpine mining area using different soil overburden thicknesses. The results showed that vegetation restoration significantly changed the species composition of soil microorganisms, especially in the 15 cm soil overburden thickness. Bacterial diversity was higher than fungal diversity in all three soil overburden thicknesses.

Summary: Ecological restoration is considered the best solution for mining-degraded areas, especially valuable ecosystems. However, the storage of topsoil can negatively affect soil fertility and microbial diversity. This study examined the evolution of topsoils stored in piles on mined areas and found that storage duration, depth, and topsoil origin all influenced microbial, fungal, and physical properties of the soil. The findings highlight the importance of minimizing stockpiling duration and reducing pile height to ensure successful ecosystem restoration.

Summary: The interactions between microbial traits and soil carbon fractions, especially mineral-associated organic carbon (MAOC), were investigated in subtropical forests. It was found that MAOC accounted for the majority of soil organic carbon (SOC) and had strong relationships with SOC. Microbial biomass and specific enzyme activities, especially bacteria, were significantly related to SOC, particularly MAOC. However, microbial traits did not predict the variation in SOC and MAOC. There were tradeoffs between microbial investment in biomass growth and resource acquisition, which were controlled by SOC, especially MAOC.

Summary: Short-term warming affects soil labile carbon pools by changing bacterial community structure, while long-term warming promotes decomposition of recalcitrant carbon pools by increasing fungal biomass and decreasing actinobacterial biomass. Factors such as actinobacterial biomass, fungal biomass, soil pH, and elevation influence the response of soil microbial communities to warming.

Summary: Biochar amendment is a promising agricultural approach to combat climate change by enhancing soil carbon sequestration. It was found that biochar addition increased soil ligninase activity targeting complex phenolic macromolecules, but suppressed cellulase activity degrading simpler polysaccharides. These shifts in enzyme activities explained variations in soil carbon sequestration in different conditions, and the ligninase:cellulase ratio correlated negatively with soil C sequestration. Short-term biochar addition reduced cellulase activity and increased soil organic C sequestration, while long-term addition enhanced ligninase activity and ligninase:cellulase ratio, resulting in a smaller increase in soil organic C sequestration. This research provides evidence for the diminished long-term soil C sequestration with biochar addition.

Summary: This study conducted a field study on a reclaimed coal gob pile in a loess hilly area in Shanxi to assess the effects of different artificially restored coniferous forest species on the soil's physico-chemical properties, bacterial community, and functional gene attributes. The results showed that there were significant differences among the different tree species in terms of bacterial community diversity and structure, as well as functional genes. PS and PA had lower pH and bulk density levels and higher soil alkaline protease, alkaline phosphatase, and urease activities. The bacterial community diversity and functional genes were highest in PS and PA. Soil bulk density and pH directly affected the soil keystone bacteria and microbial functions, and indirectly affected the soil keystone genus and microbial functions by affecting soil nutrient elements and enzyme activity. PS and PA had a significantly higher integrated fertility index score compared to the other coniferous tree species, suggesting their suitability for forest restoration projects using reclaimed soil from coal gob piles in Shanxi's mining region.

Summary: This study investigates the effects of sesquiterpene lactones (STLs) of the invasive plant Mikania micrantha on soil microbial diversity and activity. The results show that Mikania STLs can significantly increase the regulation of soil microbial activity. Specifically, the presence of dihydromikanolide, a specific STL, increases bacterial richness but decreases soil fungal richness. Dihydromikanolide also promotes the abundance of beneficial soil bacteria and fungi associated with nutrient cycling and supply, while reducing pathogen abundance.

Results showed significantly higher levels of organic carbon, total nitrogen, phosphorous, nitrate, and pH in silvopasture systems compared to woodland. The microbial diversity and community composition were also significantly influenced by the silvopasture system, with differences in dominant bacterial and fungal phyla observed between the two systems.

Summary: This study utilized gene sequencing to explore the bacterial diversity in three traditional Nigerian foods: abacha, fufu, and garri. Different dominant bacterial phyla and genera were identified in these foods, with several previously unreported bacteria found in fufu. Despite the presence of potential pathogenic genera, the foods also contained potentially beneficial species that could contribute to artisanal food production, food security, and consumer health.

Summary: The study investigated the effect of successive application of cattle dung and/or dung beetle on the diversity and ecological guild of topsoil fungal assemblages. The results showed that the application of cattle dung significantly improved fungal diversity and ecological guild. However, the addition of dung beetle along with dung may lead to vertical displacement of organic matter and ecologically relevant fungal species to deeper soil depths.
