Summary: The study found that herb communities, soil microbial biomass, and enzyme activities were strongly affected by vegetation restoration, with significant differences in soil bacterial and fungal communities among sites. Correlation analysis showed that litter biomass and fine root biomass were significantly positively correlated with the Chao index of soil bacteria, soil microbial biomass, enzyme activities, Proteobacteria, Zygomycota, and Cercozoa, while negatively correlated with Actinobacteria and Basidiomycota. Additionally, soil water content, pH, and nutrients had important effects on the bacterial and fungal diversities, with influences on Acidobacteria, Proteobacteria, Actinobacteria, Nitrospirae, Zygomycota, and microbial biomass.

Summary: This study investigated the impact of different fire frequencies on soil systems and found that only the A horizon was significantly affected by the prescribed fire interval manipulation. The richness and composition of microbial communities in the A horizon differed between the burned treatments and the unburned control. Soil chemistry changes were also observed in the A horizon, with higher levels of certain nutrients in the burned treatments compared to the fire exclusion treatment. The results indicate that long-term changes in fire frequencies can induce shifts in the soil microbial community.

Summary: This study investigates the restoration of drained peatland forests and the role of soil microbiota in the recovery process. The results show an increase in spatial heterogeneity in soil fungi and bacteria, as well as an increase in the relative abundance of saprotrophic fungi, while nitrogen content in the soil decreases significantly. However, the stability of other physico-chemical properties and fluctuations in the microbiome suggest that soil recovery will remain incomplete and patchy for decades. Thus, managing restored peatland forests requires considering an uncertain future and diverse outcomes.

Summary: Soil microbes play a critical role in belowground carbon cycling in terrestrial ecosystems. Nitrogen fertilization has been found to decrease soil microbial diversity while increasing soil organic carbon and microbial biomass carbon. However, this increase in carbon is not accompanied by an increase in microbial diversity, suggesting a weakened linkage between soil carbon and microbial diversity under nitrogen fertilization.

Summary: The interactions between rhizosphere microorganisms and pioneer plants are crucial for ecological restoration after disturbance. Different pioneer species influence the composition of rhizosphere microbial communities, with bacteria being more sensitive to environmental changes than fungi. Plant traits, rather than species composition, play a key role in shaping the microbial communities in the soil.

Summary: Understanding the effects of logging and fire on forest soil communities is crucial for forest ecology and resource management. Research in Tasmania showed that burn severity is a strong driver of soil microbial community composition, with logging and high severity burning reducing the diversity and biomass of soil bacteria and fungi. The impact of disturbance on microbial community composition is greater than site-to-site edaphic differences, and fire leads to more significant divergence in community composition than logging alone.

Summary: This study investigates the impact of different cropland management systems on microbial diversity in soil during the transition period from winter to summer. The results show that bacteria and fungi respond differently to seasonal changes, and the changes in diversity between treatments do not sync with each other. The complex interaction between land management and sampling time affects bacterial diversity more than fungal diversity. It is suggested that assessing fungal diversity between management practices can be done without considering temporal variation.

Summary: Increases in temperature are expected to facilitate the encroachment of tropical mangrove forests into temperate salt marshes. The study conducted in Louisiana, USA, compared carbon and nitrogen stocks in marshes and mangroves and found that black mangrove encroachment leads to increased aboveground carbon and nitrogen stocks. However, belowground nitrogen and carbon sequestration may not be affected. Further studies are needed to better understand the implications of mangrove encroachment on nitrogen cycling, storage, and export to the coastal ocean.

Summary: Human activities have led to a decrease in global salt marsh surface area, prompting the construction of marshes in terrestrial systems to mitigate this loss. While constructed marshes can rapidly recover ecosystem structure, the recovery of biogeochemical processes may be slow. Comparing denitrification and DNRA rates between excavation-created and natural reference salt marshes can help assess the recovery of ecosystem function.

Summary: The constructed stormwater control systems can be biogeochemical hotspots, but their ecosystem structure may become homogenized due to construction and management. Roadside ditches, a common landscape feature, have high potential for nitrate removal with denitrification and anammox processes dominating. Although soil characteristics were similar between different land use types, denitrification potential rates were lower in forested ditches compared to urban and agricultural ditches, possibly due to differences in vegetation management. Microbial diversity was consistent across land use types, but indicator species analysis showed significant microbial groups in urban and agricultural ditches involved in nitrogen removal processes. Land use effects on nitrogen removal in these constructed drainage networks are mediated through key microbial groups and ditch vegetation management strategies, indicating significant potential for reactive nitrogen removal in the landscape.

Summary: This study examined the trends in surface elevation change and sediment accretion in the Grand Bay estuary of the Gulf of Mexico. The results showed that J. roemerianus marshes located at higher elevations were more vulnerable to sea level rise, while lower elevation marshes were driven by sediment accretion and biogenic inputs. The study also suggests that marsh migration may be a potential solution for marsh persistence in this relatively undeveloped area.

Summary: Compared to the six major Arctic rivers, the Onega River, a small Arctic watershed, has higher levels of dissolved organic carbon (DOC) and organic matter (DOM) throughout the year, with pronounced seasonality in both spring and fall. This indicates that smaller northern high-latitude rivers may play a larger role in Arctic carbon flux models and the export of DOC to the Arctic Ocean than previously assumed.

Summary: Soil microbial community coalescence, the mixing and interaction of microbial communities, has been found to enhance the stability and complexity of rhizobacterial networks, leading to improved plant health and biomass. This study investigated the effects of different degrees of bacterial community coalescence on plant disease resistance by mixing soils from healthy and diseased habitats for watermelon planting. The results showed that mixing in more healthy soil reduced the plant disease index and increased biomass by improving the stability and complexity of the rhizobacterial network. Core taxa Nitrospirillum and Singulisphaera were enriched in the rhizosphere from healthy soils and played important roles in disease suppression and regulating the positive cohesion and modularity of the networks. Overall, these findings provide insights into the potential mechanism of microbial community coalescence for improving plant microbial community function and suggest new tools for enhancing plant fitness via soil microbiota mixing.

Summary: Collembolans, the diverse group of soil invertebrates, are affected by anthropogenic climate warming, which alters their diversity and density. In addition to abiotic stressors, changes in food availability, specifically the abundance of saprotrophic and mycorrhizal fungi, influence Collembola responses to climate warming. Collembolans prefer saprotrophic fungi but rely on mycorrhizal fungi when food sources are scarce. Understanding the mechanisms behind these dietary shifts in warm-dry and warm-wet soil conditions is crucial for predicting the impact of climate change on Collembola-fungal interactions.
