Heterogeneity and Controlling Mechanisms of Soil Organic Carbon Stocks Across Erosion Zones in China Under Future Climate Scenarios

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil organic carbon (SOC), as a key indicator of global carbon cycling and climate change response, plays a critical role in regional ecological security and agricultural sustainability. This study employs three machine learning models including the LightGBM, XGBoost, and random forest to simulate the spatial distribution of topsoil SOC stocks

Soil Contamination Around the Copper Smelter and the Use of Soil Microarthropods as Bioindicators

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil contamination from smelter emissions, including heavy metals (HM), rare earth elements (REEs), and sulfur, poses a significant threat to soil ecosystems. In the immediate vicinity of the Głogów Copper Smelter, HM concentrations were several times higher than in more distant forest stands.

From the sea to DNA barcode: Optimized preservation method for gelatinous zooplankton integrative taxonomy

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

Effects of preservatives and poisons on the elemental and isotopic composition of freshwater particulate organic matter

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Sediment traps, often used in tandem with preservatives or poisons, are widely used for the collection of particulate organic matter (POM), providing insight into the source to sink mechanisms that shape major biogeochemical cycles and sedimentary carbon sequestration.

Transcending the Space‐Bandwidth and Lighting Trade‐Offs: A Programmable Self‐Mixing Interferometry Imager for Cross‐Scale Surface Inspection

open access: yesLaser &Photonics Reviews, EarlyView.
This work reports a laser diode‐based self‐mixing interferometry imager featuring illumination‐invariance imaging, a 500 kHz pixel rate, and an 8.77 µm lateral resolution. It also features a programmable field‐of‐view and leading space‐bandwidth product that surpasses existing technologies by an order of magnitude, enabling cross‐scale workflow ...
