Xylem water cryogenic vacuum extraction: Testing correction methods with CaviTron-based apple twig sampling

Dong He et al.

Summary: In this study, the accuracy of three current δH-2 offset correction methods, namely 8.1 parts per thousand Mean-Correc, Line-Correc, and REHYDR, for plant water source identification was evaluated using the CaviTron centrifuge technique. The results suggest that the REHYDR and 8.1 parts per thousand Mean-Correc methods outperformed the Line-Correc method in identifying plant water sources.

Three Bayesian Tracer Models: Which Is Better for Determining Sources of Root Water Uptake Based on Stable Isotopes under Various Soil Water Conditions?

Junming Liu et al.

Summary: Stable hydrogen and oxygen isotopes are used to quantify root water uptake from different sources. Three Bayesian tracer mixing models were tested to determine the root water uptake of winter wheat under different soil water content conditions. The MixSIAR model showed better performance under normal and wet conditions.

Evidence for distinct isotopic compositions of sap and tissue water in tree stems: consequences for plant water source identification

Adria Barbeta et al.

Summary: Recent studies challenge the hypothesis that the isotopic composition of plant stem water reflects that of source water, with findings of isotopic offsets in woody stems. This study demonstrates that sap water in plant stems mirrors the composition of irrigation water, with no isotopic fractionation during root water uptake, but water in nonconductive xylem tissues is consistently depleted in deuterium. Micrometre-scale heterogeneity in water isotopes within woody stems and soil micro-pores explains source-stem isotopic offsets.

Causes and Factors of Cryogenic Extraction Biases on Isotopes of Xylem Water

Mingyi Wen et al.

Summary: Cryogenic vacuum extraction (CVE) is widely used in ecohydrological research for plant water stable isotope analysis. However, recent studies have found that CVE can introduce significant bias in stable isotope analyses, especially in deuterium values. This study conducted rehydration experiments on plant samples and found that the deuterium bias induced by CVE is linearly correlated to the xylem water content, and is influenced by plant organs/species and the isotopic signature of the spiking water.

Illuminating isotopic offset between bulk soil water and xylem water under different soil water conditions

Ying Zhao et al.

Summary: The study demonstrates that the temporal and spatial heterogeneity of soil water content affects the isotopic composition of soil water and xylem water, with larger isotopic offsets between xylem water and bulk soil water in moister areas and smaller offsets in drier areas.

Differential response of plant transpiration to uptake of rainwater-recharged soil water for dominant tree species in the semiarid Loess Plateau

Yakun Tang et al.

Summary: This study found that mixed afforestation significantly enhanced the influence of rainwater-recharged soil water uptake on plant transpiration, and there were differences in the response to rainfall pulses between the two tree species, with Hippophae rhamnoides subsp. sinensis being more sensitive.

Isotopic fractionation induced by a surface effect influences the estimation of the hydrological process of topsoil

Guo Chen et al.

Summary: This study reveals the significant role of organic matter in isotopic fractionation of soil water and analyzes the source rain of soil water using the line-conditioned excess method. After removing the influence of confined water, the average offsets of hydrogen and oxygen decreased by 5.0 and 0.5 parts per thousand, respectively.

Stable isotopes of water reveal differences in plant - soil water relationships across northern environments

Doerthe Tetzlaff et al.

Summary: Comparing stable isotopes of xylem water and soil water in northern/cold regions, it was found that xylem water is depleted compared to soil waters, with a strong overlap between isotopes in xylem water from angiosperms and soil water, but not in gymnosperms. The composition of xylem water can be better explained by considering soil water composition over longer antecedent periods.

Determination of groundwater recharge processes and evaluation of the 'two water worlds' hypothesis at a check dam on the Loess Plateau

Ying Zhao et al.

Summary: This study found that areas with shallow groundwater and check dams on the Loess Plateau in China can promote water cycling from precipitation to groundwater at a faster rate compared to tablelands with deep loess layers. The preferential and matrix flows play different roles in groundwater recharge, and when preferential flow is dominant, isotopic differences between water sources are minimal, contradicting the predictions of the 'two water worlds' hypothesis.

No evidence of isotopic fractionation in olive trees (Olea europaea): a stable isotope tracing experiment

Anam Amin et al.

Summary: In a simple glasshouse experiment, researchers found no isotopic fractionation in olive trees under specific experimental conditions, validating the traditional isotope-tracing approach. Water extracted from wood cores and twigs showed no significant differences, reflecting the signature of labelled water, while significant differences were found between plant water and deep soil water.

Contrasting adaptive strategies by Caragana korshinskii and Salix psammophila in a semiarid revegetated ecosystem

Ying Zhao et al.

Summary: Our study reveals that Salix psammophila and Caragana korshinskii exhibit different water uptake patterns and physiological performances, with C. korshinskii showing greater long-term water use efficiency than S. psammophila, despite being anisohydric. These results suggest that the environmental adaptability of C. korshinskii may generally be more ecologically plastic than that of S. psammophila. This study serves as a reference for evaluating the persistence of shrub species in relation to the management and restoration of ecosystems.

Insights into the isotopic mismatch between bulk soil water and Salix matsudana Koidz trunk water from root water stable isotope measurements

Ying Zhao et al.

Summary: Increasing field studies have found isotopic mismatches between plant trunk water and its sources. The cause of these offsets is unclear, but may be related to soil water heterogeneity. This study shows that root water isotopic composition deviates from bulk soil water, and trunk water is only isotopically similar to root water at specific depths.
