Electromagnetic (EM) methods for estimation of water content in porous media (eg, soil and
tree stems) are based on estimates of the media's bulk dielectric permittivity, which is …

A laboratory test and field evaluation were conducted to determine the accuracy of the three
commonly used techniques for measuring sap flux density in trees: heat pulse velocity …

On vegetation-covered land surfaces, tree transpiration, compared to soil and canopy
evaporation, is a major process that sends large amounts of water back to the atmosphere …

Despite its importance for urban planning, landscape management, and water management,
there are very few in situ estimates of urban‐forest transpiration. Because urban forests …

Forest evapotranspiration (ET) estimates that include scaled sap flux measurements often
underestimate eddy covariance (EC)-measured latent heat flux (LE). We investigated …

Mixtures can be more productive than monocultures and may therefore use more water,
which may make them more susceptible to droughts. The species interactions that influence …

Components of the tree water transport pathway; roots, trunks, branches and leaves; can
also serve as water storage compartments and therefore act transiently as intermediate …

Many researchers are using sap flux to estimate tree-level transpiration, and to scale to
stand-and catchment-level transpiration; yet studies evaluating the comparability of sap flux …

Forest transpiration estimates are frequently based on xylem sap flux measurements in the
outer sections of the hydro-active stem sapwood. We used Granier's constant-heating …

We investigated relationships between whole‐tree hydraulic architecture and stomatal
conductance in Pinus palustris Mill.(longleaf pine) across habitats that differed in soil …
