Climate change and land-use disturbances are supposed to have severely affected the degraded alpine grasslands on Tibetan Plateau. Artificial grassland establishment has been implemented as a restoration tool against degradation. However, impact of such degradation processes soil microbial communities quality is not clearly understood. Here, we aim investigate how dynamics community respond gradient that restoration, respectively. We conducted randomised experiment with four stages (light,...
The effects of different levels natural clay enterosorbent on the growth, nutrient availability, and genital organs post-weaning female pigs fed with an addition zearalenone (ZEA) were investigated in study.A total thirty-five gilts (L×Y×D) average body weight 12.36±1.46kg used test.The raised individually metabolism cages a corn-soybean meal-whey basal diet 0 or 1 mg/kg ZEA for 24 d four added feed.The treatments were: i) control; ii) control+2.5g/kg clay; iii) control+1 ZEA; iv) ZEA+1.25...
Abstract Biotic nitrogen (N) retention is an important ecosystem function in the context of ongoing land‐use intensification, N deposition and global warming. However, a paucity experimental evidence limits understanding how different plant community components influence terrestrial ecosystems. In this investigation, we conducted 15 labelling experiment to test properties, including species richness/diversity, dominance functional traits, uptake under nutrient availabilities. A 3‐year...
Human appropriation of net primary productivity (HANPP) is an important indicator for assessing ecological sustainability. However, the spatiotemporal dynamics HANPP in Qinghai grasslands remain unclear. In this study, we used spatially explicit Biome-BGCMuSo model to quantify and map from 1979 2018. Generally, actual (NPPact) was slightly lower than potential (NPPpot), difference between NPPpot NPPact increased over time. From 2001, were relatively stable; however, 2001 2018, both showed...
Worldwide, many plant species are experiencing an earlier onset of spring phenophases due to climate warming. Rapid recent temperature increases on the Tibetan Plateau (TP) have triggered changes in phenology local vegetation. However, remote sensing studies land surface reached conflicting interpretations about green-up patterns observed TP since mid-1990s. We investigated this issue using field phenological observations from 1990 2006, for 11 dominant plants at levels species, families...
Sinadoxa corydalifolia is a perennial grass with considerable academic value as rare species owing to habitat destruction and narrow distribution. However, its distribution remains unclear. In this study, we predicted the of in three-river region (the source Yangtze River, Yellow Lancang River) under context climate change using maximum entropy (MaxEnt) model. Under current scenario, suitable mainly occurred Yushu County Nangqian County. The area covered 3107 km2, accounting for 0.57%...
Abstract Nitrogen (N) and phosphorus (P) are associated with the life history of all organisms. Soil microbes play essential roles in nutrient cycling ecosystem dynamics. As compared to plants, however, our understanding soil microbial N versus P scaling relationship remains limited. In this study, we used a comprehensive dataset comprising 2210 observations from 422 sites worldwide examine C, N, concentrations C:N:P ratios, determine different ecosystems spatial scales (i.e. depths,...
Estimating the grassland carbon budget is critically important for ensuring that resources are used sustainably. However, spatiotemporal dynamics of and response to grazing have not yet been characterized in Qinghai grasslands. Here, we estimated gross primary productivity (GPP) net ecosystem exchange (NEE) grasslands using improved Biome-BGCMuSo model characterize this region from 1979 2018. The GPP fluctuated during study period, with an average annual value 118.78 gC/m 2 . NEE 2018, −5.16...
Large quantities of organic matter are stored in frozen soils (permafrost) within Qinghai-Tibetan Plateau (QTP). The most QTP regions particular have experienced significant warming and wetting over the past 50 y, this trend is projected to intensify future. Such climate change will likely alter soil freeze-thaw pattern permafrost active layer towards greenhouse gas nitrous oxide (N2O) release. However, interaction effect altered moisture on N2O emission during freezing thawing unclear. Here...

Abstract The succession of arbuscular mycorrhizal fungi (AMF) communities during ecosystem development has received widespread attention, but the ecological mechanism that drives AMF restoration process in alpine meadow ecosystems remains unclear. Here, we treated ‘Black Beach’ (severely degraded meadow) as baseline for (0 year), and selected revegetated grassland Elymus nutans with different planting times (3, 7, 10, 14 years) to analyze species composition community mixed roots (at...
Global warming could change plant growth, and there are differences in response among vegetation types. Plant roots an important part of production, but their to temperature is weak. Using simulated with open-top chamber, we studied the effects long-term on allocations underground biomass carbon a Kobresia humilis meadow Potentilla fruticosa shrub Qinghai-Tibet Plateau. We analyzed vertical distributions biomass, root content, soil organic content. The results show following after via...
More data are needed about how genetic variation (GV) and environmental factors influence phenotypic within the natural populations of long-lived species with broad geographic distributions. To fill this gap, we examined correlations among 13 Pinus tabulaeformis consisting four demographically distinct groups entire distributional range. Using Akaike's Information Criterion (AIC) model, measured 12 morphological traits constructed alternative candidate models for relationships between each...
The effects of climate warming and season on soil organic carbon (SOC) have received widespread attention, but how affects the seasonal changes SOC remains unclear. Here, we established a gradient experiment to investigate plant attributes physicochemical microbial properties that were potentially associated with in at beginning (May) end (August) growing an alpine meadow ecosystem Qinghai-Tibet Plateau. August was lower than May, storage decreased by average 18.53 million grams per hectare....
Abstract While most studies yield positive relationships between biodiversity (B) and ecosystem functioning (EF), awareness is growing that BEF can vary with ecological context. The has led to increased efforts understand how contemporary environmental context modifies relationships, but the role of historical context, mechanisms by which it may influence effects, remains poorly understood. We examined alters plant diversity–community productivity via species interactions in alpine...
