Oxidative stress in honey bees (Apis mellifera) and small carpenter bees (Ceratina calcarata) across different landscapes

open access: yesPhysiological Entomology, Volume 51, Issue 3, Page 526-536, September 2026.
First comparative study in oxidative stress between wild bees and managed bees. Bees collected from organic landscapes exhibited the lowest OX levels. Pesticide profiles were different among landscapes. Abstract Oxidative stress (OX) is a state of imbalance between antioxidants and reactive oxygen species, which are the byproducts of oxidative ...

Predicting the Unsaturated Hydraulic Conductivity of Compacted Polyurethane–Clay Using the Filter Paper Method

open access: yesApplied Sciences
Sanitary landfill covers are exposed to varying environmental conditions; hence, the state of the clay layer also changes from saturated to unsaturated. The study aimed to predict the unsaturated hydraulic conductivity of the locally available compacted ...

Pore Size Effect on Melting Point in Saturated Frozen Soil Systems: A Pressure Perspective at Molecular Scale

open access: yesWater Resources Research, Volume 62, Issue 8, August 2026.
Abstract The melting point depression of water confined in porous media with varying pore sizes has been widely observed. Existing models remain insufficient for describing water phase change in smaller pores (i.e., nano pore), where surface effects become significant and water molecules are inhomogeneously distributed near solid surface.

Overland Flow Dynamics on a Cracked Soil Slope Under Drying‐Wetting Cycles: An Integrated Hydrological and Infrared Thermographic Study

open access: yesWater Resources Research, Volume 62, Issue 8, August 2026.
Abstract Although overland flow strongly governs soil erosion and sediment transport, its response to desiccation cracking induced by drying‐wetting cycles is not fully understood. This study addresses this gap through laboratory rainfall simulations on a slope model subjected to three drying‐wetting cycles.

Evaluation Model of Soil Water Characteristic Curve of Red Clay Based on Dielectric Theory [PDF]

open access: yes长江科学院院报
[Objective] The soil water characteristic curve (SWCC) can effectively reflect the relationship between soil water suction (matric potential) and water content, yet conventional testing methods pose challenges for the calibration of in situ soil ...

OsPIP2;1 impacts root hydraulic conductance and is a candidate gene for a drought avoidance QTL on rice chromosome 7

open access: yesPlant Biology, Volume 28, Issue 5, Page 1602-1613, August 2026.
In this study, we identified a rice plasma membrane intrinsic aquaporin (OsPIP2;1) as the candidate gene for a chromosome 7 locus driving drought avoidance, supported by established and novel physiological experiments measuring root hydraulic conductance in near isogenic and RNAi knockdown lines.

Integrating physical and statistical models for regional rainfall‐induced landslide hazard assessment

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.
We present an event‐based FS–probability mapping to link physically based slope stability analysis with statistical probability prediction. Results indicate a mappable relationship between factor of safety and landslide probability, and the hybrid model shows comparable discriminative performance across two extreme‐rainfall events with contrasting ...

Determination of the lens water content for several different configurations of elliptical particles in unsaturated soils [PDF]

open access: yesمجله مدل سازی در مهندسی, 2018
Until now, all of the calculations about determining of water content around the particles in unsaturated soil have done with supposing the spherical shape of particles and most of quantities such as matric suction and interparticle stress due to water ...

Can one‐dimensional infiltration models reproduce soil moisture variations in landslide‐prone hillslopes? Evidence from Petrópolis, Brazil

open access: yesSoil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract The distribution of soil moisture, resulting from the movement of infiltrated water, plays a fundamental role in the hydrological dynamics of hillslopes and in the triggering of landslides. Although water flow in soils occurs in multiple directions due to combined vertical and lateral fluxes, one‐dimensional (1D) flow models are widely adopted

Calibrating the wetting front pressure head of the Green and Ampt infiltration model

open access: yesSoil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract The Green–Ampt (GA) model is a classical analytical solution of the Richards equation used to predict soil water infiltration. Based on a modified form of Darcy's law, it assumes piston‐like flow with a constant pressure head at the soil surface and in the saturated zone, separated from the unsaturated region by a sharp wetting front.
