Accurately scaling sap flux observations to tree or stand levels requires accounting for
variation in sap flux between wood types and by depth into the tree. However, existing …

X‐ray microtomography (micro CT) is becoming a valuable noninvasive tool for advancing
our understanding of plant–water relations. Laboratory‐based micro CT systems are …

In order to quantify and characterize the variance in desert riparian forest tree sap flow, we
measured the sap flow from Populus euphratica and compared the daytime and nighttime …

Understanding radial and azimuthal variation, and tree-to-tree variation, in sap flux density
(F d) as sources of uncertainty is important for estimating transpiration using sap flow …

In this study, we aimed to assess how sample sizes affect confidence of stand-scale
transpiration (E) estimates calculated from sap flux (F d) and sapwood area (A S_tree) …

In this study, we aimed to clarify spatial variations in xylem sap flow, and to determine the
impacts of these variations on stand‐scale transpiration (E) estimates. We examined …

Although it is well known that evapotranspiration (ET) represents an important water flux at
local to global scales, few studies have quantified the magnitude and relative importance of …

In this study, we employ a network of thermal dissipation probes (TDPs) monitoring sap flux
density to estimate leaf-specific transpiration (EL) and stomatal conductance (GS) in Pinus …

Abstract Tree‐mediated methane (CH4) emissions represent an uncertain pathway of the
total CH4 flux released from forested ecosystems. We measured the stem CH4 fluxes from …

Recent studies have suggested that in certain environments, tree stems emit methane
(CH4). This study explored the mechanism of CH4 emission from the stem surfaces of Alnus …
