In Mongolia, the monitoring and estimation of spring wheat yield at regional national levels are key issues for agricultural policy food management as well economy society a whole. The remote sensing data technique have been widely used crop production in world. For current research, nine indices were tested that include normalized difference drought index (NDDI), water (NDWI), vegetation condition (VCI), temperature (TCI), health (VHI), multi-band (NMDI), visible shortwave infrared (VSDI),...
Primary productivity response to climatic drivers varies temporally, indicating state-dependent interactions between climate and productivity. Previous studies primarily employed equation-based approaches clarify this relationship, ignoring the nature of ecological dynamics. Here, using 40 y data from 48 grassland sites across Mongolia, we applied an equation-free, nonlinear time-series analysis reveal sensitivity patterns change variability underlying mechanisms. We showed that responded...
The dispersion of microorganisms through the atmosphere is a continual and essential process that underpins biogeography ecosystem development function. Despite ubiquity atmospheric globally, specific knowledge determinants microbial diversity at any given location remains unresolved. Here we describe bacterial in boundary layer underlying soil twelve globally distributed locations encompassing all major biomes, characterise contribution local distant soils to observed community. Across...
Abstract Climate change will affect the way biodiversity influences stability of plant communities. Although biodiversity, associated species asynchrony, and could enhance community stability, understanding potential nonlinear shifts in biodiversity–stability relationship across a wide range aridity (measured as index, precipitation/potential evapotranspiration ratio) gradients underlying mechanisms remain limited. Using an 8‐year dataset from 687 sites Mongolia, which included 5496 records...
A new dust observation site was built in Tsogt-Ovoo, which is located the northern Gobi Desert Mongolia, to clarify wind erosion processes. Ten events were detected from March 24 May 4, 2012. Strong winds (greater than 20 m s-1 at an altitude of 3 m) blew predominantly west. Clear relationships among speed, saltation and particulate matter concentrations less 10 μm (PM10) detected. transition speed threshold for observed Julian day (JD) 111 (April 20); before JD 111, 14.0 s-1, but it...
Global warming threatens ecosystem functions, biodiversity, and rangeland productivity in Mongolia. The study analyzes the spatial temporal distributions of Net Primary Production (NPP) its response to climatic parameters. also highlights how various land cover types respond fluctuations from 2003 2018. Boreal Ecosystem Productivity Simulator (BEPS) model was used simulate NPP last 16 years. Satellite remote sensing data products were mainly as input for model, where ground-based MODIS...
Monitoring of dry vegetation in arid and semi-arid regions is crucial environmental investigations such as assessments wind erosion risk, livestock forage, fire risk. However, there has been little research into estimating the coverage mass (non-photosynthetic) vegetation. In our study area at Tsogt-Ovoo (TsO) northern Gobi Desert, Mongolia, we used MODIS data to compare observed cover (VCd_obs) (Md_obs) with values estimated from Normalized Difference Vegetation Index (NDVI) six other...
Abstract Atmospheric transport is critical to dispersal of microorganisms between habitats, and this underpins resilience in terrestrial marine ecosystems globally. A key unresolved question whether assemble form a taxonomically distinct, geographically variable, functionally adapted atmospheric microbiota. This made more complex by the unique challenges separating potential contaminants from signal, particularly given ultra-low biomass air long durations sampling where contamination may...
Abstract Atmospheric transport is critical to dispersal of microorganisms between habitats and this underpins resilience in terrestrial marine ecosystems globally. A key unresolved question whether assemble form a taxonomically distinct, geographically variable, functionally adapted atmospheric microbiome. Here we characterised globalscale patterns microbial taxonomic functional diversity air within above the boundary layer underlying soils. Bacterial fungal assemblages were structured...
Spatial information about the sand saltation threshold is essential to quantify transport and dust emission. Quantitatively estimating over a wide area challenging, however, because its main influencing factors (surface roughness elements) are unknown. Here, we explored use of Sentinel-1 Synthetic Aperture Radar (SAR) data surface conditions their temporal changes map threshold. Thresholds were obtained by in situ observations dry spring periods during 2018–2020 at three year-round eight...
We conducted a 4-year temperature manipulation experiment in Mongolian grassland to examine the effect of daytime and nighttime warming on recovery after grazing exclusion. After constructing livestock exclusion fence grassland, we established daytime-and-nighttime treatments within fenced area by combination open-top chambers (OTC) electric heaters. measured numbers plants aboveground biomass species recording percentage vegetation cover every summer for three inside fence-non-warming,...
Abstract Aridity, edaphic variables and livestock grazing are major drivers of plant community composition across arid rangelands. Accumulated knowledge exists on the impact each driver composition. Although previous studies have demonstrated changes in direct impacts ecosystem functions at different aridity levels, ranging from mesic to grasslands, whether a regional‐scale continuous spatial pattern compositional change along gradient or is altered by remains controversial. We compared...
Abstract Artemisia adamsii is a weed with low palatability to livestock and thus recognized as an indicator of rangeland degradation in Mongolia. We investigated the germination characteristics this species, phytotoxic suppression its by own residue, applicability such behaviour control species. also discussed ecological consequence these factors regarding vegetation dynamics Mongolian steppe. Germination A. was tested at different light temperature conditions. for four native grassland...

Conventional dogma that a neutral process involving ubiquitous distribution air has been challenged by recent advances 3–5 However, the lack standardized methods analytical frameworks have impeded synthesis global perspective. A key unresolved question whether assemble form taxonomically distinct, geographically variable...
