Dynamics Relationship of Phyllosphere and Rhizosphere Bacterial Communities During the Development of Bothriochloa ischaemum in Copper Tailings

open access: yesFrontiers in Microbiology, 2020
Copper mining and the byproducts associated with the industry have led to serious pollution in the Loess Plateau of China. There is a potential in improving the ecological restoration efficiency of such degraded land through combining microbial and plant

Study of the disintegration of loess modified with fly ash and Roadyes

open access: yesScientific Reports, 2023
The disintegration property of loess is the wetting and subsequent disintegration of loess in water, which is generally an important index for resistance to erosion and disintegration of wet loess slopes and foundations.

Drought-resistant trait of different crop genotypes determines assembly patterns of soil and phyllosphere microbial communities

open access: yesMicrobiology Spectrum, 2023
Crop microbiomes are widely recognized to play a role in crop stress resistance, but the ecological processes that shape crop microbiomes under water stress are unclear.

Profound effect of profiling platform and normalization strategy on detection of differentially expressed microRNAs [PDF]

open access: yes, 2012
Adequate normalization minimizes the effects of systematic technical variations and is a prerequisite for getting meaningful biological changes. However, there is inconsistency about miRNA normalization performances and recommendations.

Chemical Weathering of Loess and Its Contribution to Global Alkalinity Fluxes to the Coastal Zone During the Last Glacial Maximum, Mid‐Holocene, and Present

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Loess sediments are windblown silt deposits with, in general, a carbonate grain content of up to 30%. While regionally, loess was reported to increase weathering fluxes substantially, the influence on global weathering fluxes remains unknown.

Discrete element simulation study on micromechanical characteristics of undisturbed and remolded loess in biaxial test

open access: yes地质科技通报, 2021
Loess is a special granular material, and its mechanical properties are determined by the microscopic structure of granules. The undisturbed and remolded loess have different mechanical properties due to the difference in structure. In order to solve the

On-sample water content measurement for a complete local monitoring in triaxial testing of unsaturated soils [PDF]

open access: yes, 2012
To provide a complete local monitoring of the state of an unsaturated soil sample during triaxial testing, a local water content measurement device was adapted to a triaxial device comprising the measurement of local displacements (Hall effect ...

Deterministic processes dominate soil microbial community assembly in subalpine coniferous forests on the Loess Plateau [PDF]

open access: yesPeerJ, 2019
Microbial community assembly is influenced by a continuum (actually the trade-off) between deterministic and stochastic processes. An understanding of this ecological continuum is of great significance for drawing inferences about the effects of ...

Determining soil water characteristic curve of lime treated loess using multiscale structure fractal characteristic

open access: yesScientific Reports, 2020
Soil–Water characteristic Curve (SWCC) is meant to describe the mechanical behavior of unsaturated soil. The present paper focuses on the internal multi-scale microstructure of Xining untreated loess and lime-treated loess with the use of scanning ...
