Our study shows that sap flow in Avicennia marina varies significantly throughout the sapwood and that spatial patterns in sap flux density are dependent on meteorological conditions. Sap flux density measurements are used worldwide as a relatively inexpensive means to provide estimates of whole-tree and whole-stand water use in forest ecosystems. However, erroneous upscaling from point measurements to the entire sapwood area remains an issue, since sap flow is hardly ever constant throughout… CONTINUE READING
