Grasslands store approximately one third of the global terrestrial carbon stocks and can act as an important soil sink. Recent studies show that plant diversity increases organic (SOC) storage by elevating inputs to belowground biomass promoting microbial necromass contribution SOC storage. Climate change affects grassland modifying processes catabolism anabolism. Improved grazing management biodiversity restoration provide low-cost and/or high-carbon-gain options for natural climate solutions in grasslands. The achievable sequestration potential grasslands is 2.3 7.3 billion tons dioxide equivalents per year (CO2e year-1) restoration, 148 699 megatons CO2e year-1 improved management, 147 sown legumes pasturelands.

In macroecology, the concept of r- and K-strategy has been widely applied, yet, there have limited studies on microbial life-history strategies in temperate grasslands using multiple sequencing approaches. Total phospholipid fatty acid (PLFA) analysis, high-throughput meta-genomic sequencing, GeoChip technologies were used to examine changes traits a chronosequence restored (1, 5, 10, 15, 25, 30 years since restoration). Grassland restoration increased relative abundances Actinobacteria, Proteobacteria, Bacteroidetes but reduced Acidobacteria, Planctomycetes, Chloroflexi. PLFA analysis revealed that grassland fungi:bacteria Gram-positive:Gram-negative bacteria ratios. Combined with data, we found shifted microorganisms from oligotrophic (K-) copiotrophic (r-) groups, consistent rRNA operon copy number community. Structural equation modeling showed soil properties positively (

Afforestation is an effective approach to rehabilitate degraded ecosystems, but often depletes deep soil moisture. Presently, it not known how afforestation-induced decrease in moisture affects microbial community and functionality, hindering our ability understand the sustainability of rehabilitated ecosystems. To address this issue, we examined impacts 20 years afforestation on bacterial community, co-occurrence pattern, functionalities along vertical profile (0-500 cm depth) a semiarid region China's Loess Plateau. We showed that effects with deep-rooted legume tree cropland were greater than top layers, resulting decreased beta diversity, more responsive taxa functional groups, increased homogeneous selection, network robustness soils (120-500 cm). Organic carbon nitrogen decomposition rates multifunctionality also significantly by afforestation, limitation soils. Moreover, changes functionality layer was largely related Such negative should be fully considered for assessing afforestation's eco-environment ecosystems because have important influence forest arid climates.

Plant communities strongly influence soil microbial and, in turn, carbon (C) cycling. Microbial use efficiency (CUE) is an important parameter for predicting C accumulation, yet how plant and community traits CUE remains poorly understood. Here, we determined influenced by traits, studying a natural gradient of species diversity subtropical forest. Our results showed that increased with increasing tree diversity, suggesting correlation between storage. The specific properties explained the greatest variation were associated (biomass, enzyme activities ratio oligotrophic to copiotrophic taxa); there weaker correlations plant-input properties, chemistry organic quality its mineral protection. Overall, high was correlated diversity: higher substrate availability (simple SOM chemical structures weak associations) growth rates despite dominance strategists. point mechanism which may increase forest sink affecting community.

Although pervasive microplastics (MPs) pollution in terrestrial ecosystems invites increasing concern, impact of MPs on soil microbial community assembly, and ecosystem functions multifunctionality received relatively little attention. Here, we manipulated a mesocosm experiment to investigate how polyethylene (PE MPs; 0, 1%, 5%, w/w) influence plant production, quality, diversity enzymology carbon (C), nitrogen (N) phosphorus (P) cycling, maize–soil continuum. Results showed that PE exerted negligible effect biomass (dry weight). The 5% caused declines the availability water, C P, whereas enhanced pH storage. activity C-cycling enzymes (α/β-1, 4-glucosidase, β-D-cellobiohydrolase) was promoted by 1% MPs, while β-1, 4-glucosidase inhibited MPs. reduced N-cycling (protease urease), increased P-cycling enzyme (alkaline phosphatase). shifted composition, number specialist species, stability networks resistance. altered with concentration decreasing dispersal limitation proportion (from 13.66 9.96%). Overall, improved concentration, α/β-1, urease, protease, ammonium-N content were most important predictors multifunctionality.
