Water stable isotopes (18O and 2H) are widely used as ideal tracers to track water through
the soil and to separate evaporation from transpiration. Due to the technical developments in …

Stable isotope ratios of hydrogen and oxygen have been applied to water cycle research for
over 60 years. Over the past two decades, however, new data, data compilations, and …

This open access book is an outcome of the collaboration between the Soil and Water
Management & Crop Nutrition Section, Joint FAO/IAEA Division of Nuclear Techniques in …

Partitioning of evapotranspiration (ET) into evaporation from the soil (E) and transpiration
through the stomata of plants (T) is challenging but important in order to assess biomass …

We apply and compare three widely applicable methods for estimating ecosystem
transpiration (T) from eddy covariance (EC) data across 251 FLUXNET sites globally. All …

Leaf water contains naturally occurring stable isotopes of oxygen and hydrogen in
abundances that vary spatially and temporally. When sufficiently understood, these can be …

Separating evapotranspiration (ET) into evaporation (E) and transpiration (T) is challenging
but key for a better understanding and prediction of the hydrological cycle and plant water …

Drylands cover about 40% of the terrestrial land surface and account for approximately 40%
of global net primary productivity. Water is fundamental to the biophysical processes that …

Plants rely primarily on rainfall infiltrating their root zones–a supply that is inherently
variable, and fluctuations are predicted to increase on most of the Earth's surface. Yet …

Deuterium depletions between stem water and source water have been observed in coastal
halophyte plants and in multiple species under greenhouse conditions. However, the …
