Heat pulse methods can be used for accurate measurements of sap flow in plant stems
provided a reliable calibration procedure is used to relate the measured heat pulse velocity …

Sap-flow measurements have become increasingly important in plant science. Since the
early experiments with dyes, many methods have been developed. Most of these are based …

Severe droughts endanger ecosystem functioning worldwide. We investigated how drought
affects carbon and water fluxes as well as soil-plant-atmosphere interactions by tracing …

Water scarcity contributes to the poverty of around one-third of the world's people. Despite
many benefits, tree planting in dry regions is often discouraged by concerns that trees …

The compensation heat pulse method (CHPM) is of limited value for measuring low rates of
sap flow in woody plants. Recent application of the CHPM to woody roots has further …

Sap flow measurements with thermometric methods are widely used to measure
transpiration in plants. Different method families exist depending on how they apply heat …

Plant roots transfer water between soil layers of different water potential thereby significantly
affecting the distribution and availability of water in the soil profile. We used a modification of …

Understanding and modeling water exchange in arid and semiarid ecosystems is
complicated by the very heterogeneous distribution of vegetation and moisture inputs, and …

Sap flow measurement techniques and evaluation of data are reviewed. Particular attention
is paid to the trunk segment heat balance (THB) and heat field deformation (HFD) methods …

The compensation heat-pulse method for measuring sap flow is tested here in olive trees
(Olea europaea L.). We describe a rigorous three-way examination of the robustness of the …
