Spatial pattern and driving factors of biomass carbon density for natural and planted coniferous forests in mountainous terrain, eastern Loess Plateau of China

open access: yesForest Ecosystems, 2020
Background Understanding the spatial pattern and driving factors of forest carbon density in mountainous terrain is of great importance for monitoring forest carbon in support of sustainable forest management for mitigating climate change.

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 ...

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 ...

Study of loess pore structure characteristics based on CT scanning

open access: yes地质科技通报, 2022
Porosity is one of the important characteristics reflecting the microstructure of loess and directly affects the physical and mechanical properties of loess, such as water sensitivity, permeability and strength.

Does rock type account for variation in mussel attachment strength? A test with Brachidontes rodriguezii in the southwestern Atlantic [PDF]

open access: yes, 2018
Mussel attachment strength varies in space and time, frequently in association with variations in wave exposure. Yet, it remains uninvestigated whether different rock types can contribute to variation in mussel attachment. Here we compared the attachment

Experimental study on seismic subsidence characteristics of structural loess under cyclic torsional shear

open access: yesYantu gongcheng xuebao, 2020
The undisturbed loess has significant structural and dynamic vulnerability. Under the earthquake, the dynamic shearing action destroys the original structure of loess.

Bench Plot and Mixed Effects Models: First steps toward a comprehensive benchmark analysis toolbox [PDF]

open access: yes, 2008
Benchmark experiments produce data in a very specific format. The observations are drawn from the performance distributions of the candidate algorithms on resampled data sets.

The hidden influence of protozoa on hydrophyte-epiphytic bacterial communities

open access: yesGlobal Ecology and Conservation
Plants and their epiphytic microorganisms synergistically participate in biogeochemical cycling and pollutant removal in wetlands, but the assembly mechanisms of epiphytic microbial communities remain unclear.

Predation has a significant impact on the complexity and stability of microbial food webs in subalpine lakes

open access: yesMicrobiology Spectrum, 2023
Microbial food webs are drivers of material circulation and energy flow in lake ecosystems. The structural shifting of microbial food webs has important implications for the function of lake ecosystems.

Experimental study on the cyclic resistance of a natural loess from Northern France [PDF]

open access: yes, 2009
In order to analyze the instability phenomenon observed along the Northern High Speed Line of R\'eseau Ferr\'e de France (RFF), soil blocks were taken at a site near the railway, at four different depths (1.2, 2.2, 3.5 and 4.9 m).
