Summary: Increasing global temperatures accelerate soil carbon cycling and promote nitrogen and phosphorus dynamics in terrestrial ecosystems. Warming differentially affects ecosystem carbon, nitrogen, and phosphorus dynamics, intensifying imbalances between soil resources, plants, and soil microorganisms. Long-term soil warming shifts microbial element limitation from carbon to carbon-phosphorus co-limitation, with significant consequences for soil carbon, nitrogen, and phosphorus cycles under warming.

Summary: Climate changes and anthropogenic nutrient enrichment have negative impacts on plant diversity and ecosystem functions. Soil microbes, particularly arbuscular mycorrhizal fungi (AMF), play a crucial role in mediating plant community response to nutrient enrichment. Shifts in mycorrhizal responsive plants' competitive abilities can drive plant community change to anthropogenic eutrophication, highlighting the importance of mycorrhizal mutualism in ecological restoration following soil community degradation.

Summary: Traditionally, it was believed that phosphorus (P) fertilization relieved the limitation of soil microbial activity by providing P. Recent studies, however, suggest that the stimulation of microbial respiration is actually due to the release of carbon (C) from soil minerals caused by P, which increases microbially available C and stimulates microbial respiration. This new understanding has implications for interpreting the effects of P fertilization on other soil microbe-mediated processes.

Summary: In this study, the Multiple Element Limitation (MEL) model was used to examine the responses of 12 ecosystems to elevated CO2, warming, and changes in precipitation. The results showed that ecosystems responded synergistically to the combined effects of elevated CO2, warming, and decreased precipitation, while the response to the combined effects of elevated CO2, warming, and increased precipitation was additive. The study also analyzed the factors attributing to changes in ecosystem carbon based on nitrogen and phosphorus, and found that different ecosystems exhibit different C-nutrient interactions, which shape their carbon sequestration under simulated global change.

Summary: In this study, the associations between soil organic nitrogen (SON) content and microbial community characteristics across different aggregate sizes were investigated using data from a long-term field fertilization experiment in paddy soils. The results showed that SON content decreased as aggregate size decreased, and keystone microbial clusters were significantly correlated with SON content. Functional prediction analysis suggested metabolic pathways involved in biosynthesis of N-containing compounds present in keystone microbial clusters may contribute to this relationship. Overall, this study highlights the importance of keystone microbial clusters in influencing the accumulation of SON and contributes to our understanding of soil N biogeochemical cycling.

Summary: Soils in alpine ecosystems store a large amount of organic carbon, with a significant portion sorbed to reactive soil minerals. This study examined the effects of air warming, nitrogen input, and precipitation changes on calcium- and iron-associated carbon dynamics in a Tibetan alpine meadow. The results showed that high rainfall significantly increased the concentrations of calcium- and iron-associated carbon, likely due to increased soil moisture and the promotion of their formation through Ca-binding to clay surfaces or increased solubility of Fe oxides.

Summary: Rapid urbanization has significant impacts on global biodiversity, but its effects on soil biodiversity and nematodes are not well understood. In this study, we examined soil nematodes in four land-use types across 12 cities in China. We found that urban parks and nearby forests had higher nematode richness than urban residential areas and surrounding farmlands. Nematode communities in parks and residential areas were more similar, while forests and farmlands had more heterogeneous communities. The variations in nematode communities were mainly due to taxa replacement, indicating spatial isolation of nematodes in cities. Urban parks served as hotspots for soil nematodes, while residential areas had the lowest number of specialists and smaller body sizes. Overall, our findings suggest that urbanization reduces nematode diversity, leading to a 30% loss in residential areas compared to forests, and homogenizes soil nematode communities.

Summary: Soil multifunctionality is influenced by biotic interactions and energy flux among multitrophic groups in the soil food web. Biochar can increase multifunctionality by promoting energy flow through the nematode food web, while synthetic fertilizer can have a non-uniform effect. Nitrogen limitation may offset the benefits of biochar and nutrient impoverishment can promote energy flow through the herbivore channel. Balancing biochar and synthetic fertilizer application is crucial for maintaining stable energetic structure and improving crop production and soil health in subtropical regions.

Summary: The soil microbial food web is crucial for soil health, nutrient cycling, and agricultural productivity. However, the effects of heavy metal contamination on the trophic-level interactions within this food web in agricultural soils, which are globally contaminated, have not been well-studied. This study examined the interactions among predators, preys, and competitors under different metal contamination levels and found that metal contamination altered the growth of different prey groups, resulting in changes in the diversity and abundance of consumers and their interactions. Lab experiments confirmed these findings, indicating the collapse of trophic-level interactions due to heavy metal contamination.

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.
