Abstract Soil respiration ( R s ) is the second‐largest terrestrial carbon (C) flux. Although has been extensively studied across a broad range of biomes, there surprisingly little consensus on how spatiotemporal patterns will be altered in warming climate with changing precipitation regimes. Here, we present global synthesis data from studies that have manipulated field by collating 113 increased treatments, 91 decreased and 14 prolonged drought treatments. Our meta‐analysis indicated when...
Abstract Anthropogenic nitrogen (N) input is known to alter plant and microbial α‐diversity, but how N enrichment influences β‐diversity of communities remains poorly understood. Using a long‐term multilevel addition experiment in temperate steppe, we show that plant, soil bacterial fungal exhibited different responses their input. Plant decreased linearly as increased, result increased directional environmental filtering, where properties largely explained variation β‐diversity. Soil first...
Rapid warming in the Arctic has a huge impact on global environment. Atmospheric brown carbon (BrC) is one of least understood and uncertain agents due to scarcity observations. Here, we performed direct observations atmospheric BrC quantified its light-absorbing properties during 2-month circum-Arctic cruise summer 2017. Through observation-constrained modeling, show that BrC, mainly originated from biomass burning mid- high latitudes Northern Hemisphere (∼60%), can be strong agent region,...
Mercury is a global pollutant that can transform into methylmercury, highly toxic and bioaccumulative organic form. Previous surveys have shown fish the main source of human methylmercury exposure, whereas most other food products an average value below 20 µg/kg primarily in inorganic This paper reports rice (Oryza sativa L.) grown at abandoned mercury mining areas contained levels >100 its edible portion proved to be 10−100 times higher than crop plants. The daily adult intake through...
The imbalance between nitrogen (N) and phosphorus (P) deposition may shift temperate ecosystems from N- to P-limitation. However, it is unclear how the imbalanced N : P input affects strategies of plants acquire and, therefore, growth competition among species. We conducted a 4-yr N-addition experiment in young mature larch (Larix principis-rupprechtii) stands. Plant acquisition were assessed for understorey vegetation. addition stimulated aboveground productivity vegetation stand stand,...
Abstract Bactrocera dorsalis is one of the most economically important fruit flies around world. In this study, 454 pyrosequencing was used to identify bacteria associated with different developmental stages B. . At ≥ 97% nucleotide similarity, total reads could be assigned 172 Operational Taxonomic Units belonging six phyla. Proteobacteria dominated in immature while Firmicutes adult stages. The abundant families were Enterococcaceae and Comamondaceae genus Comamonas pupae whereas...
Grassland is one of the largest terrestrial biomes, providing critical ecosystem services such as food production, biodiversity conservation, and climate change mitigation. Global land-use intensification have been causing grassland degradation desertification worldwide. As primary medium for energy flow biogeochemical cycling, carbon (C) cycling most fundamental process maintaining services. In this review, we first summarize recent advances in our understanding mechanisms underpinning...
Summary Litter in arid and semi‐arid ecosystems usually exhibits a prolonged standing dead phase after senescence; however, we know little about the ways which abiotic microbial processes affect litter decomposition. We conducted 26‐month situ decomposition experiment steppe to investigate potential mechanisms governing of litter, 192‐day laboratory incubation further explore impacts stage on subsequent soil organic carbon (SOC) formation falls surface. Compared with surface has higher...
Abstract The 70-kD heat shock proteins (Hsp70s) are highly conserved molecular chaperones that play essential roles in cellular processes including abiotic stress responses. Physcomitrella patens serves as a representative of the first terrestrial plants and can recover from serious dehydration. To assess possible relationship between P. Hsp70s dehydration tolerance, we analyzed genome found at least 21 genes encoding Hsp70s. Gene structure motif composition were relatively each subfamily....
Global warming has greatly altered winter snowfall patterns, and there is a trend towards increasing snow in semi-arid regions China. Winter an important source of water during early spring these water-limited ecosystems, it can also affect nutrient supply. However, we know little about how changes will ecosystem productivity plant community structure the growing season. Here, conducted 5-year manipulation experiment temperate grassland Inner Mongolia. We measured carbon flux from 2014 to...
Abstract Climate‐induced changes in snow cover can greatly impact winter soil microclimate and spring water supply. These effects, turn, influence plant microbial activity the strength of leaching processes, potentially altering distribution storage organic carbon (SOC) across different depths. However, few studies have examined how will affect SOC stocks, even less is known about on dynamics along profiles. By selecting 11 fences a 570 km climate gradient Inner Mongolia, covering arid,...
Abstract Background The eastern oyster, Crassostrea virginica (Gmelin 1791), is an economically important species cultured in many areas North America. It also ecologically because of the impact its filter feeding behaviour on water quality. Populations C. have been threatened by overfishing, habitat degradation, and diseases. Through genome research, strategies are being developed to reverse population decline. However, large-scale expressed sequence tag (EST) resources lacking for this...
Seedling establishment is inhibited on media containing high levels (∼6%) of glucose or fructose. Genetic loci that overcome the inhibition seedling growth sugar have been identified using natural variation analysis and mutant selection, providing insight into signaling pathways. In this study, a quantitative trait locus (QTL) was performed for sensitivity to in Col/C24 F2 population Arabidopsis thaliana. A fructose-sensing QTL, GSQ11, mapped through selective genotyping confirmed...
Chloroplasts are essential for photosynthesis and play critical roles in plant development. In this study, we characterized the temperature-sensitive chlorophyll-deficient rice mutant tcd5, which develops albino leaves at low temperatures (20 °C) normal green high (32 °C). The development of chloroplasts etioplasts is impaired tcd5 plants 20 °C, period phenotype P4 stage leaf thylakoid membranes arrested mid-P4 °C. We performed positional cloning TCD5 then complementation knock-down...
Summary Forest canopies can retain nitrogen (N) from atmospheric deposition. However, most empirical and modeling studies do not consider the processing of N deposited in canopy. To assess whether deposition through canopy will alter plant’s uptake retention, we conducted a 3‐yr mesocosm experiment by applying ( 15 NH 4 ) 2 SO solution to aspen sapling or directly soil. We found that N‐NH + applied was taken up leaves. Compared with soil application, application resulted higher...
