Trait-based approaches provide a candidate framework for linking soil microbial community to ecosystem processes, yet how the trade-offs in different traits regulate community-level metabolic efficiency remains unknown. Herein we assessed roles of taxa with particular trait strategies mediating along an altitude gradient on Tibetan Plateau. Results showed that declined increasing altitude, as indicated by quotient (microbial respiration per unit biomass, qCO2) and decreasing carbon use...
Warming is known to reduce soil carbon (C) stocks by promoting microbial respiration, which associated with the decomposition of residue (MRC). However, relative contribution MRC organic (SOC) across temperature gradients poorly understood. Here, we investigated SOC along two independent elevation our model system (i.e., Tibetan Plateau and Shennongjia Mountain in China). Our results showed that local increases were negatively correlated SOC. Further analyses revealed rising reduced via...
Microbial residues contribute to the long-term stabilization of carbon in entire soil profile, helping regulate climate planet; however, how sensitive these are climatic seasonality remains virtually unknown, especially for deep soils across environmental gradients. Here, we investigated changes microbial along profiles (0-100 cm) from 44 typical ecosystems with a wide range climates (~3100 km transects China). Our results showed that account larger portion deeper (60-100 vs. shallower (0-30...
ABSTRACT Biochar amendment is one of the most promising agricultural approaches to tackle climate change by enhancing soil carbon (C) sequestration. Microbial‐mediated decomposition processes are fundamental for fate and persistence sequestered C in soil, but underlying mechanisms uncertain. Here, we synthesise 923 observations regarding effects biochar addition (over periods ranging from several weeks years) on C‐degrading enzyme activities 130 articles across five continents worldwide. Our...
Microbial communities in soils are generally considered to be limited by carbon (C), which could a crucial control for basic soil functions and responses of microbial heterotrophic metabolism climate change. However, global C limitation (MCL) has rarely been estimated is poorly understood. Here, we predicted MCL, defined as availability substrate relative nitrogen and/or phosphorus meet metabolic requirements, based on the thresholds extracellular enzyme activity across 847 sites (2476...
Soil biodiversity contains the metabolic toolbox supporting organic matter decomposition and nutrient cycling in soil. However, as soil develops over millions of years, buildup plant cover, carbon microbial biomass may relax dependence functions on biodiversity. To test this hypothesis, we evaluate within-site function relationships across 87 globally distributed ecosystems ranging age from centuries to millennia. We found that relationship is negatively correlated with age, suggesting a...
Abstract Paddy fields are hotspots of microbial denitrification, which is typically linked to the oxidation electron donors such as methane (CH 4 ) under anoxic and hypoxic conditions. While several anaerobic methanotrophs can facilitate denitrification intracellularly, whether how aerobic CH couples with in paddy remains virtually unknown. Here we combine a ~3300 km field study across main rice-producing areas China 13 -DNA-stable isotope probing (SIP) experiments investigate role soil...
Abstract Drylands are characterized by stressful conditions with the limitation of both carbon (C) and nutrients, particularly nitrogen (N) phosphorus (P). Biological C, N, P releases from soil organic matter enzymes essential components for biogeochemical cycles sensitive to climate in drylands. However, how ecoenzymatic C:N:P stoichiometry responds environmental factors (i.e., climatic edaphic factors) over broad geographical scales remains largely unclear. We examined patterns ratios...
Abstract The Walker and Syers model of phosphorus (P) transformations during long‐term soil development has been verified along many chronosequences but rarely examined climosequences, particularly in arid regions. We hypothesized that decreasing aridity would have similar effects on P as time by increasing the rate pedogenesis. To assess this, we fractions semiarid grassland soils (0‐10 cm) a 3700 km gradient northern China (aridity between 0.43 0.97, calculated 1 − [mean annual...
Bioaccumulation of the neurotoxin methylmercury (MeHg) in rice has raised worldwide concerns because its risks to human health. Certain microorganisms are able degrade MeHg pure cultures, but roles and diversities microbial communities degradation paddy soils unknown. Using a series microcosms, we investigated from Hunan, Guizhou, Hubei provinces, representing three major production regions China, further characterized one Hunan Province for associated with degradation. Microbial...
Soil-borne fungal phytopathogens are important threats to soil and crop health. However, their community composition environmental determinants remain unclear. Here, we explored the effects of agricultural fertilization regime (i.e., organic material application) on phytopathogens, using data sets from a combination field survey long-term experiment. We found that carbon was key factor affected diversity relative abundance in soils. The dominant genera including
The neurotoxin methylmercury (MeHg) is produced mainly from the transformation of inorganic Hg by microorganisms carrying hgcAB gene pair. Paddy soils are known to harbor diverse microbial communities exhibiting varying abilities in methylating Hg, but their distribution and environmental drivers remain unknown at a large spatial scale. Using hgcA amplicon sequencing, this study examined Hg-methylating major rice-producing paddy across transect ∼3600 km an altitude ∼1300 m China. Results...
Abstract The turnover of soil organic carbon (SOC) is primarily regulated by extracellular enzymes secreted the microorganism. However, how C‐decomposition respond to different land use change remains unclear. Here, we conducted a study explore seasonal variations in enzyme activities including hydrolases (α‐glucosidase, β‐glucosidase, cellobiohydrolase, and β‐xylosidase) oxidases (polyphenol oxidase peroxidase) woodland, shrubland, cropland, adjacent uncultivated soils central China. Soil...
Soil pollution is an important stressor affecting biodiversity and ecosystem functioning. However, we lack a holistic understanding of how soil microbial communities respond to heavy metal in agricultural ecosystems. Here, explored the distribution patterns inter-kingdom interactions entire microbiome (including bacteria, fungi, protists) 47 paired paddy upland fields along gradient legacy mercury (Hg) pollution. We found that richness composition protistan community had stronger responses...
Returning straw to the field, coupled with fertilizer application, is an effective means improve fertility of black soil in Northeast China. Previous studies have mainly focused on physical and chemical properties structure fertility. However, few efforts been made study impact returning microbial community Here, we studied typical northeast Heilongjiang Province characterize effects long-term application its bacterial structure. High-throughput sequencing was conducted under different...
