Plant Water Use and Isotopic Tracing in Shrubland Hydrology
Investigates how shrubs like rabbitbrush access and transport water through the soil-plant-atmosphere continuum, using stable water isotopes and sap flow sensors to trace water sources and quantify transpiration in dryland ecosystems.

Concept (9) →
groundwater
stable water isotopes
Naturally occurring isotopes of hydrogen (²H) and oxygen (¹⁸O) in water molecules used to trace water sources and movement through soil-plant systems
transpiration
The movement of water from the soil to the plant's stomata which is then released into the atmosphere, serving as an indicator of plant water status
lignin content
vapor pressure deficit
The difference between the amount of moisture in the air and how much moisture the air can hold when it is saturated, indicating evaporative demand
compensatory water uptake
Process where trees shift their root water uptake from topsoil towards subsoil to sustain transpiration rates when shallow soil moisture declines
stable isotope mixing model
Analytical framework using isotopic signatures to determine proportional contributions of different water sources to plant water uptake
potentiometric surface
sapflow
