Relationships between casts of geophagous earthworms (Lumbricidae, Oligochaeta) and matric potential - I. Cast production, water content, and bulk density

, 1994
Laboratory experiments were conducted to investigate the effects of matric potential on the rate of cast production, and water content and bulk density of casts.

Construction of a model of subsoil moisture movement in cultivated slope lands

Аграрная наука Евро-Северо-Востока
Insufficient study of the dynamics of moisture movement both in the soil loosened by the tillage tool and in the zone of uncultivated subsoil wall in the conditions of moisture deficient south of Russia necessitated for development of a mathematical ...

Opening the black box: in situ imaging of arbuscular mycorrhizal fungal structures in soil using synchrotron‐based micro‐CT

New Phytologist, EarlyView.
Summary Arbuscular mycorrhizal fungi (AMF) contribute to plant nutrient and water uptake via their extraradical hyphal networks. However, in situ methodologies to quantify architectural and morphological traits of these networks in soil are largely lacking, limiting our understanding of AMF‐mediated resource transport.

Calculation of Steady-State Evaporation for an Arbitrary Matric Potential at Ground Surface [PDF]

, 2015
In the past few decades, many researchers have studied evaporation from soil columns in the presence of a water table. Several water retention functions have been developed to describe the water flow behavior in the field environment.

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

Plant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Matric potential measurements by polymer tensiometers in cropped lysimeters under water-stressed conditions

, 2008
In many regions of the world, plant growth and productivity are limited by water deficits. As a result of more frequent and intense droughts, the area of land characterized as very dry has more than doubled since the 1970s.

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.
