Soil organic carbon (SOC) and soil inorganic (SIC) are key components of pools in arid ecosystems, playing a crucial role regional cycling climate change mitigation. However, the interactions between these two forms alpine ecosystems remain underexplored. This study was conducted Heihe River Basin (HRB) northeastern Qinghai–Tibet Plateau, focusing on distribution dynamics SOC SIC deep layers. Using data from 329 samples collected 49 profiles extending to bedrock, combined with path analysis,...
ABSTRACT The Qinghai‐Tibet Plateau (QTP) has an extensive frozen soil distribution and intense geological tectonic activity. Our surveys reveal that earthquakes can not only damage infrastructure but also significantly impact carbon dioxide emissions. Fissures created by expose deep, soils to the air and, in turn, accelerate We measured average emission rates of 968.53 g CO 2 m −2 ·a −1 on fissure sidewall 514.79 at bottom. estimated total flux from fissures caused M ≥ 6.9 326 B.C. 2022 is...
Abstract Oxygen (O 2 ) is the most abundant molecule in atmosphere after nitrogen. Previous studies have documented that oxygen concentration remains nearly constant (20.946%) at all altitudes. Here we show for first time varies significantly from earlier consensus and shows strong spatial seasonal differences. Field observations on Qinghai-Tibetan Plateau (QTP) indicate of 19.94–20.66% (2018, n = 80), 19.98–20.78% (2019, 166) 19.97–20.73% (2020, 176), statistically different reports ( p...
The dominant fracture can be effectively plugged by injecting self-degradable diverters during temporary plugging fracturing. subsequent fracturing fluids divert into the poor fractures. complexity enlarged and well production enhanced. This study established a new diverter evaluation system carried out 23 groups of experiments to investigate characteristics within three-dimensional (3D) hydro-fractures. Experimental results show that (1) formation process zone is determined bridging...
Abstract Moored current observations in the northwestern South China Sea (SCS) captured two events of near‐inertial waves (NIWs) induced by tropical cyclones Conson and Mindulle, which propagated to seafloor from base mixed layer. The time taken Conson‐induced kinetic energy (NIKE) reach bottom ocean was approximately 12 days. This NIKE twice as fast Mindulle‐induced ocean, mainly dependent on properties NIWs deeply affected background vorticity. upper layer Conson/Mindulle showed a...
Hairgrass (Deschampsia caespitosa), a widely distributed grass species considered promising in the ecological restoration of degraded grassland Qinghai-Xizang Plateau, is likely to be subjected frequent drought and waterlogging stress due ongoing climate change, further aggravating degradation this region. However, whether it would acclimate water stresses resulting from extreme climates remains unknown. Proline accumulation crucial metabolic response plants challenging environmental...
In this study, a 100 g sample of Saxifraga atrata was processed to separate 1.3 11-O-(4′-O-methylgalloyl)-bergenin (Fr1) after 1 cycle MCI GEL® CHP20P medium pressure liquid chromatography using methanol/water. Subsequently, COX-2 affinity ultrafiltration coupled with reversed-phase successfully used screen for potential ligands in target fraction (Fr1). After 20 runs, 74.1 mg >99% pure (Fr11) obtained. addition, the anti-inflammatory activity further validated through molecular docking...
For the ecologically vulnerable Qinghai-Tibet Plateau (QTP), hypoxia is increasingly becoming an extremely important environmental risk factor that significantly affects health of both humans and livestock in plateau region, as well hindering high-quality development. To focus on problem hypoxia, it especially urgent to study surface oxygen concentration (i.e., concentration). However, existing research not sufficient, there a lack data collected QTP. In this study, through Second Tibetan...
Marine submerged buoys can effectively obtain various parameters of seawater, which plays an important role in the research marine physical phenomena, environmental changes, and climate change. However, traditional self-contained usually work underwater at a depth about 100 m, observation data cannot be obtained before their recovery, satisfy needs real-time acquisition for scientific research. To solve this problem, paper proposes communication subsurface mooring system that consists...
Environmental pollution and medicine safety have aroused increasing public concerns due to human health. Amongst various contaminants, mercury is of special attention owing their environmental persistence biogeochemical recycling ecological risks. Herein, a simple highly parallel electrochemical biosensor for Hg determination was designed investigated. The proposed prepared compared between (1) DTT/MB-DNA/Au with configuration occupation approach (2) MCH/MB-DNA/Au passivation approach....
The Qinghai-Tibet Plateau (QTP) has three main grassland types: alpine meadow, steppe, and desert steppe. In this study, we asked how plant productivity species diversity vary with altitude, longitude latitude in grasslands of the QTP. We then identified environmental factors that drive these observed patterns diversity. found although varied greatly across large-scale longitudinal latitudinal gradients, changes were strongest gradient. This finding indicates moisture rather than temperature...

Abstract In general, tropical cyclones (TCs) will inject energy into oceanic inertial motion‒a prevalent phenomenon in the ocean. Under global warming, intensity of TCs is on rise, while their frequency has exhibited a decline since 2000. However, long-term trend this infusion an underexplored problem context. Using damped-slab model, we computed wind work exerted by ocean’s mixed-layer motions. Our results show that increased approximately 50% from 1979 to 2023. The increase strong...
Livestock snow disaster is one of the most serious natural disasters in pastoral areas during cold seasons, leading to substantial livestock losses over past few decades. Accurate assessment exposure crucial for reducing risk disaster, while much less known about due lack available gridded density data with long time series. In this study, datasets large livestock, sheep and total at a spatial resolution 1 km across Qinghai Plateau (QP) 1983–2018 were generated by developing models...
In this study, we undertook the first complete Ochotona erythrotis mitochondrial genome. The genome sequence was 16,663 bp in length, including typical structure of 22 transfer RNA genes, 13 protein-coding 2 ribosomal and non-coding control region. overall base composition O. mitogenome is 31.8% A, 26.0% T, 28.6% G, 13.6% C, with a high A + T content 57.8%.
Medicago sativa (alfalfa) is a widely used animal feed. However, its quality has been difficult to control due the lack of appropriate marker compounds. Therefore, it very necessary select an (Q-marker) quality. In this study, medium-pressure liquid chromatography and high-pressure were employed effectively prepare separation Q-marker (L-tryptophan) from sativa. Firstly, using MCI GEL® CHP20P as stationary phase, 2.5 g target fraction Fr3 was enriched crude extract (2.9 kg) by...
