Abstract Soil organic carbon (SOC) persistence is predominantly governed by mineral protection, consequently, soil mineral-associated (MAOC) and particulate (POC) turnovers have different impacts on the vulnerability of SOC to climate change. Here, we generate global MAOC POC maps using 8341 observations then infer turnover times a data-model integration approach. Global storages are $${975}_{964}^{987}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msubsup> <mml:mrow>...

Abstract Aim The aim was to explore how conversions of primary or secondary forests plantations agricultural systems influence soil microbial communities and carbon (C) cycling. Location Global. Time period 1993–2017. Major taxa studied Soil microbes. Methods A meta‐analysis conducted examine effects forest degradation on properties attributes related biomass, activity, community composition diversity based 408 cases from 119 studies in the world. Results Forest decreased ratios K...
Abstract Aim Climate change intensifies the hydrological cycle and consequently alters precipitation regimes. Accurately assessing future carbon (C) budgets depends on understanding influence of altered both aboveground C cycling belowground processes. Our goal was to explore generalities mechanisms responses soil microbial communities implications for in terrestrial ecosystems. Location Global. Time period 2001–2017. Major taxa studied Soil microbes. Methods We used meta‐analytical...
Increases in carbon (C) inputs to soil can replenish organic C (SOC) through various mechanisms. However, recent studies have suggested that the increased input also stimulate decomposition of old SOC via priming. Whether loss by priming override replenishment has not been rigorously examined. Here we show, data-model synthesis, magnitude is greater than priming, resulting a net increase mean 32% added new C. The positively correlated with nitrogen-to-C ratio substrates. Additionally, model...
Soil priming is a microbial-driven process, which determines key soil-climate feedbacks in response to fresh carbon inputs. Despite its importance, the microbial traits behind this process are largely undetermined. Knowledge of role these integral advance our understanding how soil microbes regulate (C) emissions forests, support largest stocks globally. Using metagenomic sequencing and 13 C-glucose, we provide unprecedented evidence that explain unique portion variation across forest biomes...
Soil organic carbon (SOC) is a key component of the global cycle yet it not well represented in Earth system models to accurately predict dynamics response climate change. This novel study integrated deep learning, data assimilation, 25,444 vertical soil profiles, and Community Land Model version 5 (CLM5) optimize model representation SOC over conterminous United States. We firstly constrained parameters CLM5 using observations profiles both batch mode (i.e., all individual layers one batch)...
The microbial priming effect-the decomposition of soil organic carbon (SOC) induced by plant inputs-has long been considered an important driver SOC dynamics, yet we have limited understanding about the direction, intensity, and drivers across ecosystem types biomes. This gap hinders our ability to predict how shifts in litter inputs under global change can affect climate feedbacks. Here, synthesized 18,919 observations CO2 effluxes 802 soils globe test relative effects (i.e., log response...
Abstract Aim Fresh carbon (C) inputs to the soil can have important consequences for decomposition rates of organic matter (priming effect), thereby impacting delicate global C balance at soil–atmosphere interface. Yet, environmental factors that control priming effect intensity remain poorly understood a scale. Location Global. Time period 1980–2020. Major taxa studied Soil intensity. Methods We conducted dataset CO 2 effluxes in 711 pairwise soils with 13 or 14 simple sources and without...
The sequence of physiological events during drought strongly impacts plants' overall performance. Here, we synthesized the global data stomatal and hydraulic traits in leaves stems 202 woody species to evaluate variations water potentials for key their along climatic gradient. We found that seasonal minimum potential, turgor loss point, closure leaf stem xylem vulnerability embolism were intercorrelated decreased with aridity, indicating stress drives trait co-selection. In xeric regions,...
Soil microbial growth, a vital biogeochemical process, governs both the accrual and loss of soil carbon. Here, we investigate biogeography microbiome potential growth rates show that microbiomes in resource-rich (high organic matter nutrients) acid-neutral soils from cold humid regions exhibit high growth. Conversely, resource-poor, dry, hot, hypersaline soils, display lower rates, suggesting trade-offs between resource acquisition or stress tolerance. In addition, positively correlates with...
<p>Altered precipitation regimes as a result of global climate change have significant implications for ecosystem processes, such the decomposition litter, vital process in carbon (C) and nutrient cycling terrestrial ecosystems. However, effects altered on litter across humid arid biomes remain unresolved. To address this knowledge gap, we conducted comparative analysis using data from geographically replicated precipitation‒manipulation field experiment that studied meta-analysis 778...
