An explanation for the isotopic offset between soil and stem water in a temperate tree species
Barbeta, A.; Gimeno, T.E.; Clavé, L.; Fréjaville, B.; Jones, S.P.; Delvigne, C; Wingate, L.; Ogée, J. (New Phytologist Trust, 2020)A growing number of field studies report isotopic offsets between stem water and its potential sources that prevent the unambiguous identification of plant water origin using water isotopes. We explored the causes of this ... -
Disentangling the Role of Forest Structure and Functional Traits in the Thermal Balance of the Mediterranean–Temperate Ecotone
Barbeta, A.; Miralles, D.G.; Mendiola, L.; Gimeno, T.E.; Sabaté, S.; Carnicer, J. (Journal of Geophysical Research: Biogeosciences, 2023-06-01)The thermal balance of forests is the result of complex land–atmosphere interactions. Different climate regimes and plant functional types can have contrasting energy budgets, but little is known about the influence of ... -
Isotopic offsets between bulk plant water and its sources are larger in cool and wet environments
De La Casa, J.; Barbeta, A.; Rodríguez-Uña, A.; Wingate, L.; Ogée, J.; Gimeno, T.E. (Hydrology and Earth System Sciences, 2022)Isotope-based approaches to study plant water sources rely on the assumption that root water uptake and within-plant water transport are non-fractionating processes. However, a growing number of studies have reported offsets ... -
Unexplained hydrogen isotope offsets complicate the identification and quantification of tree water sources in a riparian forest
Barbeta, A.; Jones, S.P.; Clavé, L.; Wingate, L.; Gimeno, T.E.; Fréjaville, B.; Wohl, S.; Ogee, J. (EGU Publications, 2019)We investigated plant water sources of an emblematic refugial population of Fagus sylvatica (L.) in the Ciron river gorges in south-western France using stable water isotopes. It is generally assumed that no isotopic ... -
Water taken up through the bark is detected in the transpiration stream in intact upper-canopy branches
Gimeno, T.E.; Stangl, Z.R.; Barbeta, A.; Saavedra, N.; Wingate, L.; Devert, N.; Marshall, J.D. (Plant Cell and Environment, 2022)Alternative water uptake pathways through leaves and bark complement water supply with interception, fog or dew. Bark water-uptake contributes to embolism-repair, as demonstrated in cut branches. We tested whether bark ...
