Illuminating hydrological processes at the soil‐vegetation‐atmosphere interface with water stable isotopes

M Sprenger, H Leistert, K Gimbel… - Reviews of …, 2016 - Wiley Online Library
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 …

The two water worlds hypothesis: ecohydrological separation of water between streams and trees?

JJ McDonnell - Wiley Interdisciplinary Reviews: Water, 2014 - Wiley Online Library
Recent work in ecohydrology has shown that in some forested watershed systems, streams
and trees appear to return different pools of water to the hydrosphere. Thus far, evidence for …

Global separation of plant transpiration from groundwater and streamflow

J Evaristo, S Jasechko, JJ McDonnell - Nature, 2015 - nature.com
Current land surface models assume that groundwater, streamflow and plant transpiration
are all sourced and mediated by the same well mixed water reservoir—the soil. However …
