ABSTRACT Carbon use efficiency (CUE) of microbial communities in soil quantifies the proportion organic carbon (C) taken up by microorganisms that is allocated to growing biomass as well used for reparation cell components. This C amount subsequently involved turnover, partly leading necromass formation, which can be further stabilized soil. To unravel underlying regulatory factors and spatial patterns CUE on a large scale across biomes (forests, grasslands, croplands), we evaluated 670 individual data obtained three commonly approaches: (i) tracing substrate 13 (or 14 C) incorporation into respired CO 2 (hereafter C‐substrate), (ii) 18 O from water DNA ( O‐water), (iii) stoichiometric modelling based activities enzymes responsible nitrogen (N) cycles. The global mean depends approach: 0.59 C‐substrate approach, 0.34 O‐water approaches. Across biomes, was highest grassland soils, followed cropland forest soils. A power‐law relationship identified between growth rates, indicating faster utilization corresponds reduced losses maintenance associated with mortality. Microbial rate increased content C, total N, phosphorus, fungi/bacteria ratio. Our results contribute understanding linkage rates CUE, thereby offering insights impacts climate change ecosystem disturbances physiology consequences cycling.

Abstract Identifying tipping points in the relationship between aridity and gross nitrogen (N) cycling rates could show critical vulnerabilities of terrestrial ecosystems to climate change. Yet, global pattern N response across remains unknown. Here, we collected 14,144 observations from 451 15 N‐labeled studies used segmented regression identify threshold responses soil process‐related variables index (AI), which decreases as increases. We found on a scale that increasing reduced nitrate consumption but increased nitrification capacity, mainly due microbial biomass carbon (MBC) (MBN) pH. Threshold production retention was observed ecosystems. In croplands, extractable were inhibited with below AI ~0.8–0.9 ammonia‐oxidizing archaea bacteria, while opposite favored above this threshold. grasslands, mineralization immobilization decreased ~0.5 MBN, true forests, stimulated ~1.0 C/N ratio, ammonium ~1.3 total MBC/MBN ratio. Soil dissimilatory reduction globally forests when ~1.4 passed. Overall, suggest any projected increase change is likely reduce plant availability arid regions enhancing it humid regions, affecting provision ecosystem services functions.

Abstract Background Microbial contributions to soil organic carbon formation have received increasing attention, and microbial use efficiency is positively correlated with storage. Mainbody This work reviews the impact on from six constraints, including plant community composition diversity, pH, substrate quality, nutrient availability stoichiometric ratios, texture aggregates, water thermal external inputs. In general, response of showed large uncertainty above positive-, negative-, or non-correlation. However, some factors are biased, more likely promote inhibit efficiency. For example, input (N, P, K, Ca) tended efficiency, while climate warming negative influence. Conclusion Further, overwhelming works focused single constraint, we suggest importance consider synergistic influence multiple environmental variables special for regulation mechanism biological-environmental interactions.

Abstract Due to increasing anthropogenic pressure, over half of the world’s tropical forests are reforested or afforested secondary plantations. The recovery pace and potential these depend largely on soil microbially-mediated biogeochemical cycling. Here we measured extracellular enzyme activities quantified microbial metabolic limitations using a vector analysis in bare land (BL, representing original state before restoration), two sites [i.e. restored forest (MF) managed Eucalyptus exserta plantation (EP)] nearby undisturbed (UF) south China. Results showed that metabolisms were co-limited by carbon (C) phosphorus (P) across four forests. Both C P higher BL than UF. Microbial limitation significantly reduced after restoration only MF when compared BL, but it was still Interestingly, enhanced both EP did not differ between Structural equation modeling (SEM) primarily attributed use efficiency, while co-driven plant biomass, efficiency availability. These findings suggest could be gradually recovered southern China, which would facilitate organic accumulation. However, underlines necessity develop optimal management
