Global change has the potential to alter soil carbon (C) inputs from above- and below-ground sources, with subsequent influences on microbial communities ecological functions. Using data a 13-year field experiment in semi-arid grassland, we investigated effects of litter manipulations plant removal microbiomes ecosystem multifunctionality (EMF). Litter addition did not affect α-diversity whereas reduced bacterial fungal due decreased C substrate supply moisture. By contrast, led larger declines α-diversity, lower network stability complexity. EMF was enhanced by but largely removal, primarily attributed loss diversity.

ABSTRACT Climate warming has caused widespread global concern. However, how affects soil microbial diversity, richness, and community structure on a scale remains poorly understood. Here we conduct meta‐analysis of 945 observations from 100 publications by collecting relevant data. The results show that field experiments significantly modify temperature (+1.8°C), water content (−3.2%), pH (−0.04). does not alter the bacteria fungi. Warming‐induced changes in variables (i.e., ΔSoil content, ΔpH), ΔTemperature experimental duration are important factors influencing responses to warming. In addition, bacterial α‐diversity (Shannon index) decreases (−3.4%) when is 3–6 years, β‐diversity increases (35.2%) exceeds 6 years. Meta‐regression analysis reveals positive correlation between change Shannon index ΔpH. Moreover, produces more pronounced effects fungal sites with moderate mean annual (MAT, 0°C–10°C) than higher (> 10°C) or lower (< 0°C) MAT. Overall, this study provides perspective response microorganisms climate improves our knowledge

Agricultural plastic mulch enhances crop yields but leads to persistent microplastic contamination in soils. Concurrently, nitrogen (N) fertilization and atmospheric deposition profoundly reshape microbial ecosystems. This study examined the individual interactive effects of polyethylene microplastics (PE, 1% w/w) addition (N, 180 kg ha−1 yr−1) on soil protist communities rape (Brassica napus L.) productivity. High-throughput sequencing soil–plant trait analyses revealed that PE alone reduced water retention biomass while elevating total carbon content, C/N ratios, NH₄⁺-N/NO₃−-N levels. Conversely, N significantly boosted chlorophyll likely through enhanced nutrient availability. Strikingly, combined PE_N treatment exhibited antagonistic interactions; diversity functional group composition stabilized resemble control conditions, under showed no difference from CK (with basal fertilizer only), despite significant reductions alone. Soil dynamics (e.g., SWC ratio) community structure collectively explained 96% variation. These findings highlight potential mitigate microplastic-induced degradation, offering a pragmatic strategy stabilize productivity contaminated agricultural systems. underscores importance balancing management with pollution sustain health global pressures.

With the extensive utilization of plastic products, microplastics/nanoplastics (MPs/NPs) contamination not only poses a global hazard to environment, but also induces new threat growth development and nutritional quality plantation agricultural products. This study thoroughly examines behavior MPs/NPs, including their sources, entry routes into plants, phytotoxicity under various biotic abiotic stresses (e.g., salinity, polycyclic aromatic hydrocarbons, heavy metals, antibiotics, plasticizers, nano oxide, naturally occurring organic macromolecular compounds, invasive Botrytis cinerea mycorrhizal fungi.) controlling strategies. MPs/NPs in systems mainly originate from mulch, sewage, compost fertilizer, municipal solid waste, pesticide packaging materials, etc. They enter plants through endocytosis, apoplast pathways, crack-entry modes, leaf stomata, affecting phenotypic, metabolic, enzymatic, genetic processes such as seed germination, metabolism, photosynthesis, oxidative stress antioxidant defenses, fruit yield nutrient quality, cytotoxicity genotoxicity. can interact with other environmental stressors, resulting synergistic, antagonistic, or neutral effects on phytotoxicity. To address these challenges, this review highlights strategies mitigate toxicity, novel green biodegradable plastics, plant extraction immobilization, exogenous regulator interventions, porous nanomaterial modulation, biocatalysis enzymatic degradation. Finally, identifies current limitations future research directions critical field.

The equilibrium transformation of soil microbial community dynamics and succession across various temporal spatial dimensions plays a critical role in maintaining plant adaptability. Intensive agricultural practices accelerate the communities, rendering their restoration function more vulnerable. Climate change, with its variable impacts, affects resilience communities through regulatory mediating effects. Investigating spatiotemporal context climate change offers valuable insights into developing robust resilient ecosystems. This review examines resources interactive effects on resource regulation, prediction structures allocation. Additionally, it explores mechanisms that sustain ecological systems, emphasizing application profit-averaging law.
