Abstract Soil microfauna play a crucial role in maintaining multiple functions associated with soil phosphorous, nitrogen and carbon cycling. Although both diversity multifunctionality are strongly affected by climate warming, it remains unclear how their relationships respond to different levels of warming. We conducted 3‐year multilevel warming experiment five treatments subtropical primary forest. Using infrared heating systems, the surface temperature plots was maintained at 0.8, 1.5, 3.0 4.2°C above ambient (control). Our findings indicated that low‐level (+0.8–1.5°C) increased multifunctionality, as well nematode protist diversity, compared control. In contrast, high‐level (+4.2°C) significantly reduced these variables. also identified significant positive correlations between 0–10 cm layer. Notably, we found did not change under 3.0°C treatment. results imply increase around 3°C may represent critical threshold forests, which is great importance for identifying response measures global from perspective soil. provide new evidence on regulate varying degrees forests.

Despite extensive research on the impact of warming and nitrogen deposition soil organic carbon components, response mechanisms microbial community composition enzyme activity to remain poorly understood. This study investigated effects components in Tibetan Plateau alpine meadow elucidated regulatory characteristics, including community, activity, stoichiometry, components. Results indicated that both significantly increased carbon, readily oxidizable dissolved biomass carbon. The interaction between influenced with reaching maximum values W0N32 treatment, while peaked W3N32 treatment. Warming also Cellobiohydrolase, β-1,4-N-acetylglucosaminidase, leucine aminopeptidase, alkaline phosphatase. decreased C: N ratio C:P but N:P ratio, had opposite effect. bacterial Chao1 index Shannon under conditions, particularly N32 whereas there were no significant changes fungal addition. Structural equation modeling revealed directly by negative positive deposition. Furthermore, altered composition, specifically Gemmatimonadota Nitrospirota , resulting a phosphatase β-xylosidase, ratios. In summary, meadows primarily depend communities, stoichiometric characteristics.

Excessive nitrogen (N) fertilization harms the diversity, structure, and function of soil microbiome. Yet, whether such adverse effects can be repaired through reducing subsequent N rate remains not completely clear so far. Here, using a long-term N-overfertilized wheat-maize cropping field, we assessed effect various proportions over six years on crop productivity, physicochemical biochemical properties, Five treatments were employed in our field experiment: farmers’ conventional (zero reduction, as control) reduction by 20%, 40%, 60%, 100%. The results showed that moderate (20–40%) enhanced productivity fertility but did affect enzyme activity. Soil bacterial fungal community diversity insensitive to whereas their structures changed significantly, with more prominent alteration community. Functional prediction indicated average relative abundance arbuscular mycorrhizal fungi increased ectomycorrhizal decreased. Moderate species interactions and, thus, provided complex cross-kingdom microbial co-occurrence network. Both assembly governed stochastic processes, this was altered reduction. Overall, response microbiome greatly dependent reduced proportion. findings obtained here shed light importance optimal intensively cultivated, high-input grain production system.

Endophytes play a pivotal role in protecting host plants from both biotic and abiotic stresses, promoting the production of active components (AC) plant growth. However, succession endophyte community Eucommia ulmoides (E. ulmoides), particularly assembly function, has not been extensively investigated. In this study, we employed high-throughput sequencing bioinformatics tools to analyze diversity across different tree ages, parts, periods. We examined population differences, correlations, mechanisms, functional roles these endophytes. Functional predictions via PICRUSt2 revealed that most endophytic fungal functions were linked biosynthesis, with significant differences biosynthetic abundance parts contrast, metabolic activity bacteria remained stable periods parts. Correlation analysis further confirmed strong positive relationship between ACs certain fungi. Among them, phyla Ascomycota Basidiomycota identified as key contributors metabolism chlorogenic acid (CA), while Aucubin was significantly positively correlated several bacteria. These findings provide valuable insights into mechanism E. endophytes, well their symbiotic relationships.
