Stable isotope analysis of root water uptake in urban endemic plants of north-central Texas using centrifugation

This database compiles 414 samples of thoughfall, soils, roots, and stems collected over different seasons in north-central Texas (USA). It records key variables including sample type, sampling date, extracted water (EW, %), total water content (TWC, %), stable isotope compositions (δ¹⁸O, δ²H), deuterium excess (d-excess), and the associated seasonal context. The dataset enables analyses of water sources, plant–soil interactions, and hydrological processes across temporal and ecohydrological variations.
