The extent to which leaf water D-enrichment (transpiration) and soil water D-enrichment (evaporation) affect the D/H ratio of plant leaf waxes remains a contentious issue, with important implications for paleohydrologic reconstructions. In this study we measure dD values of precipitation (dDp), groundwater (dDgw), plant xylem water (dDxw) and leaf water (dDlw) to understand their impact on the ...

Emerging fields of research in electronic plants (e-plants) and agro-nanotechnology seek to create more advanced control of plants and their products. Electronic/nanotechnology plant systems strive to seamlessly monitor, harvest, or deliver chemical signals to sense or regulate plant physiology in a controlled manner. Since the plant vascular system (xylem/phloem) is the primary pathway used to...

Transpiration-driven electrokinetic generators are fast emerging as an autonomous energy harvesting technology due to their spontaneous and continuous power generation at mild conditions. While biomass materials have enabled the construction of green transpiration-driven generators, current designs impeded by problems such low production, narrow operation conditions, difficulty in large-scale f...

Evapotranspiration (ET) is the primary component of the forest hydrologic cycle, which includes plant transpiration, canopy rainfall interception, and soil evaporation. Quantifying ET processes and potential biophysical regulations is needed for assessing forest water management options. Loblolly pines are widely planted in the coastal plain of the Southeastern US, but their water use is rarely...

Understanding the contributions of soil water evaporation (E) and crop transpiration (T) to evapotranspiration (ET) is essential for irrigation management improving use efficiency. Current methods partitioning ET are subject uncertainties, due in part scale differences determining E, T, ET. In this study, a lysimeter planted with maize (Zea mays L.) was partitioned into E T using sensors that h...

16 17 Climate variability and climate change induce important intra-and inter-annual variability of 18 precipitation that significantly alters the hydrologic cycle. The surface water budgets and the plant or 19 ecosystem water use efficiency (WUE) are in turn modified. Obtaining greater insight into how 20 climatic variability and agricultural practices affect water budgets and regarding their ...
