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

Physiological Entomology, EarlyView.
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 ...

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

Plant Biology, EarlyView.
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.

Maize is stressed by salt rather than water under drip irrigation with soil matric potential higher than −50 kPa in an arid saline area

, 2021
Water scarcity and soil salinization are the top abiotic stresses impeding agricultural production in arid and semi-arid regions. To evaluate maize growth is depressed by water stress or salt stress independently as well as in combination under drip ...

CrustCheck: a conceptual framework for interpreting biocrust trait–function relationships in drylands

Restoration Ecology, EarlyView.
Abstract Introduction Biocrusts are increasingly recognized for their contribution to soil stability, hydrology, nutrient cycling, and energy balance in drylands, yet practical field methods for assessing functional roles are limited. Existing approaches typically rely on cover estimates, taxonomic identification, or laboratory analyses, providing ...

Water and Gas Exchange Responses of Five Related Blueberry Species (Ericaceae spp.) to the Dry Season in the High‐Andean Forest of the Colombian Eastern Cordillera

Plant-Environment Interactions, Volume 7, Issue 4, August 2026.
ABSTRACT Vaccinium, Cavendishia, and Macleania are typical genera of blueberries from the Ericaceae belt, a narrow ecosystem that connects the high Andean forest and páramo, where fragmentation makes the species more vulnerable to climate change. To answer the question of whether five related blueberry species could physiologically behave similarly in ...

Variable Pore Connectivity Model Linking Gas Diffusivity and Air-Phase Tortuosity to Soil Matric Potential

, 2012
Soil-gas diffusivity (D-p/D-o) and its dependency on soil matric potential (psi) is important when taking regulative measures (based on accurate predictions) for climate gas emissions and also risk-mitigating measures (based on upper-limit predictions ...

When do root hairs matter for water uptake? Root hair traits to enhance plant water use and drought resilience under contrasting soil textures

Crop and Environment
Although root hairs (RHs) have been shown to enhance root-soil contact and soften the gradients in matric potential across the rhizosphere, our mechanistic understanding of how RH traits (length, density, and shrinkage) collectively affect water uptake ...

Fine‐root trait variation in temperate trees follows arc‐shape pattern along deep soil profiles

New Phytologist, Volume 251, Issue 3, Page 1101-1115, August 2026.
Root trait variation along the soil depth profile in four temperate tree species. Summary Roots are plants' interface with the soil, controlling access to water and nutrients. Yet, fine‐root trait variation along deep soil profiles and its functional implications remain poorly understood.

Soil Bacterial Community Associated With High Potato Production and Minimal Water Use

Frontiers in Environmental Science, 2019
In agriculture, water consumption for crop production represents 69% of all water use. Precision irrigation systems based on available soil water have been developed to improve crop production, reducing water use.

Surface Energy Partitioning Biases in Major Reanalyses Revealed by Soil Moisture Drying Dynamics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Identifying the flux partition regimes between soil moisture (SM) and evaporative fraction (EF, ratio of evapotranspiration to available energy) is important for understanding the hydrometeorological processes as well as the development of Land Surface Models (LSMs).
