Central Asia comprises a large fraction of the world’s drylands, known to be vulnerable climate change. We analyzed inter-annual trends and impact variability in vegetation greenness for from 1982 2011 using GIMMS3g normalized difference index (NDVI) data. In our study, most areas showed an increasing trend during 1982–1991, but experienced significantly decreasing 1992–2011. Vegetation changes were closely coupled variables (precipitation temperature) 1982–1991 1992–2011, response...
Abstract Many parts of the world have experienced frequent and severe droughts during last few decades. Most previous studies examined effects specific drought events on vegetation productivity. In this study, we characterized in China from 1982 to 2012 assessed their productivity inferred satellite data. We first occurrence, spatial extent, frequency, severity using Palmer Drought Severity Index ( PDSI ). then impacts China's terrestrial ecosystems Normalized Difference Vegetation NDVI...
Abstract The semi-arid ecosystems dominate the inter-annual variability of global carbon sink and driving role is becoming increasingly important. However, impacts climate change on dynamics water fluxes in are still not well understood. We used a data-driven (or machine learning) approach, along with observations from number FLUXNET sites spatially continuous satellite meteorological data, to generate gridded flux estimates for regions globally, then examined magnitude, spatial patterns,...
Increasing trends in vegetation productivity have been identified for the last three decades many regions northern hemisphere including China. Multiple natural and human factors are possibly responsible increases productivity, while their relative contributions remain unclear. Here we analyzed long‐term China using satellite‐derived normalized difference index (NDVI) assessed relationships of NDVI with a suite (air temperature, precipitation, photosynthetically active radiation (PAR),...
Uzbekistan, located in Central Asia, harbors high diversity of woody plants. Diversity wood-inhabiting fungi the country, however, remained poorly known. This study summarizes basidiomycte (poroid and corticoid plus similar taxa such as Merismodes, Phellodon , Sarcodon ) (Agaricomycetes, Basidiomycota) that have been found Uzbekistan from 1950 to 2020. work is based on 790 fungal occurrence records: 185 recently collected specimens, 101 herbarium specimens made by earlier collectors, 504...
Abstract Regional estimates of biogenic carbon fluxes over North America from both atmospheric inversions (“top‐down” approach) and terrestrial biosphere models (“bottom‐up”) remain highly uncertain. We merge these approaches with an ensemble‐based, regional modeling system able to diagnose quantify the causes uncertainties in top‐down sink America. Our ensemble approach quantifies partitions uncertainty stemming transport, biosphere, large‐scale CO 2 boundary inflow (boundary conditions)....
Abstract Accurate assessment of forest carbon dynamics is a critical element appraising forest‐based Natural Climate Solutions. National inventory and analysis (FIA) data provide valuable pool‐based estimates stocks, but have been underutilized to inform cycle modeling for with stand development. This study introduces hierarchical assimilation (HDA) framework optimize parameters by incrementally assimilating measured pool into the model. We found that most stocks could be reproduced...
The Lower Mekong Basin (LMB) has a typical monsoon climate, with high temperatures and an uneven distribution of precipitation throughout the year. This combined geographic position LMB, led to increase in frequency extreme weather events over last decade. However, few previous studies have used remote-sensing data investigate impact such events, particularly severe droughts, on biological productivity LMB. To address this, we assessed drought vegetation LMB during 2000–2011 using MOD17...
Abstract Accurate and fine‐scale estimates of biogenic carbon fluxes are critical for measuring monitoring the biosphere's responses feedback to climate system. Currently available data products from flux towers model‐intercomparison projects struggle adequately represent spatiotemporal dynamics surface fluxes, quantify their uncertainties, which also crucial atmospheric inversion systems. To address these gaps, we introduce a new perturbed‐parameter model ensemble with CASA estimate at...

Abstract Atmospheric CO 2 measurements from a dense surface network can help to evaluate terrestrial biosphere model (TBM) simulations of Net Ecosystem Exchange (NEE) with two key benefits. First, gridded flux estimates be evaluated over regional scales, not possible using tower observations at discrete locations for evaluation. Second, TBM ability explain atmospheric fluctuations due the directly tested, an important objective anthropogenic emissions monitoring observations. Here, we...

Abstract Background Tumor glycolysis is a critical event for tumor progression. Docetaxel widely used as first-line drug chemotherapy and shown to have survival advantage. However, the role of docetaxel in remained poorly understood. Methods The effect proliferation were performed by CCK-8, Western blotting, real-time PCR, glucose, lactate detection IHC. ChIP luciferase assay analyze mechanism on Smad3-mediated HIF-1α transactivity. Results In this study, we showed that treatment led...
Black carbon (BC), an important component of atmospheric aerosol, plays a significant role in regional climate, hydrological cycle, variation monsoon rainfall, and human health. The 40-year detailed BC over China from 1981 to 2020 is systematically investigated through the MERRA-2 reanalysis dataset. generally showed good correlation (R = 0.68) compared with 673 monthly samples ground-based observation at 35 stations around China. overall annual average concentration 1.15 μg/m3, fast growth...
