Using branch and basal trunk sap flow measurements to estimate whole-plant water capacitance: Comment on Burgess and Dawson (2008)

Sap flow sensors are uniquely able to continuously monitor whole tree physiology. Recently, Burgess and Dawson (Burgess SSO, Dawson TE, Plant Soil 305:5-13, 2008) urged caution in using sap flow probes to estimate water storage use in trees. Here we respond to three criticisms raised there: (1) Samp...
