Other claims from this paper (7)
- Observation Total water content and mobile extractable water were higher in spring and reduced during summer months across all three species.
- Observation Spring precipitation inputs promoted relatively small δ¹⁸O offsets (±1 ‰) between throughfall, soils, roots and stems across all species.
- Observation During summer and early fall, evapoconcentration resulted in higher δ¹⁸O offsets between throughfall, roots and stems.
- Observation In winter, the deciduous species boxelder maple and elderberry showed larger δ¹⁸O offsets between throughfall, roots and stems.
- Mechanism The authors interpret the winter offsets as a legacy-type effect, older water stored from the summer season.
- Observation Longitudinal analysis revealed δ¹⁸O and d-excess heterogeneity along the root system.
- Method / resource Centrifugation is a reliable method for extracting mobile water in stems and roots in a sub-tropical environment.
