Summary: The study found that agricultural intervention significantly increased total phosphorus in agricultural and disturbed peatlands, decreased soil organic carbon content and total nitrogen in surface soil of agricultural peatlands, and yet total nitrogen significantly accumulated at 20-30 cm depth in both types of peatlands. Enzyme activities of N-acetyl-13-glucosaminidase and phosphatase declined in agricultural peatlands, with a stronger decrease in phosphatase in disturbed peatlands.

Summary: Climate change accelerates glacial retreat and provides an opportunity to study the temporal development of ecosystems. This study analyzed long-term data and found that carbon and nitrogen nutrient pools increased rapidly over time, while potassium, calcium, magnesium, and phosphorus nutrient pools decreased. The availability of phosphorus also varied between different types of soil.

Summary: Long-term phosphorus fertilizer input can impact the abundance and composition of functional soil microorganisms and genes involved in the carbon, nitrogen, phosphorus, and sulfur cycles. Understanding the mechanisms regulating these cycles under different phosphorus inputs is crucial for sustainable phosphorus management in agroecosystems.

Summary: The study found that salt tolerance and nutrient cycling characteristics of aquatic microbiomes changed with increasing salinity along a gradient from freshwater to marine environments, with different diversity trends observed between the water column and sediment. Microbial communities in different habitats adopted divergent strategies for osmoregulation, and dominated distinct processes in carbon, nitrogen, and sulfur cycling.

Summary: The fundamental processes for the biodeterioration of stone and metal involve similar microbially mediated reactions, but the differences lie in the nature of the substratum and the composition of the surroundings. Biofilms play a significant role in the deterioration of metals, while phototrophic organisms are important in the deterioration of stone. The reactions and time frames for failure are distinct for stone and metal structures.

Summary: This study investigated the effects of microbial and environmental factors on potentially active phosphorus in factory compost. The results showed that chicken manure had higher available phosphorus throughout the composting process compared to kitchen waste, and also exhibited higher microbial diversity. Certain bacteria were identified as the core bacteria involved in bioavailable phosphorus conversion in both composts. Moisture and pH were identified as key environmental factors influencing bioavailable phosphorus.

Summary: The study of the Haast chronosequence in New Zealand revealed that the soil microbial communities exhibited a high diversity along with ecosystem development, while the succession of soil fungal communities was associated with tree basal area and organic phosphorus accumulation. The ratio of Bacteria:Fungi decreased in a competitive and interconnected soil community, indicating changing dynamics within the ecosystem.

Summary: This study demonstrates the extensive microbial-driven nitrogen cycling in an Asian glacier, indicating that biological processes in the interior of glaciers play a significant role in biogeochemical cycles. The research shows that microbial nitrification gradually replaces atmospheric nitrate in the glacier, and there are nitrate sinks in the firn layers due to microbial assimilation and denitrification. The findings suggest that glacier microbiota and their nutrient cycling may become increasingly important in the future, especially with predicted global warming and higher nitrogen loads.

Summary: This study explores the factors influencing the relationships between microbial diversity and soil nutrient cycling in complex terrestrial ecosystems. It reveals that the balance between positive and negative bacterial-fungal associations plays a crucial role in determining the strength of these relationships. Understanding these factors can help manage soil microbial communities for better provisioning of ecosystem services.

Summary: This study investigated the patterns of plant-microbial N/P limitation in forests across China and found significant divergence between the two. The N/P limitation was disconnected in 42.6% of plant-microbial communities, with only 17.7% of N and 39.7% of P limitations consistent. The divergence was more evident at mid-latitudes, where plants were mainly N limited and microbes were mainly P limited. The findings were consistent with ecological stoichiometry and highlighted the importance of soil chemistry in driving the divergence.

Summary: This study investigated the soil factors influencing the development of biological denitrification inhibition (BDI) and found that initial soil moisture, ammonium concentration, and the initial abundance of certain microbial genes play significant roles in BDI development. Additionally, the research highlighted the relevance of biotic factors in explaining BDI and proposed the use of procyanidin concentration from plant belowground system as a new proxy for measuring BDI intensity.

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: Maize genotypes directly affect gene expression and nitrogen uptake capacity. The feedback between maize genotypes and soil nitrogen transformations, as well as their regulations on nitrogen uptake capacity, have been studied. The findings suggest that maize genotypes play a central role in regulating these feedbacks, which are important for maize breeding and enhancing maize production.

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.
