Disentangling the Effects of Tree and Soil Properties on the Water Uptake of a Waterlogging Tolerant Tree in the Yangtze River Delta, China

Waterlogging tolerant tree species exert a critical role in forest preservation and the associated water conservation flood prone areas. Clarifying patterns drivers of uptake by waterlogging trees is crucial for management flood-prone areas, especially scenario precipitation changes estuary delta. Here, we uploaded values δD δ18O obtained from soil xylem waters to Bayesian mixed model (MixSIAR) determine use pattern Taxodium distichum, tree, following different magnitudes rainfall events three sites Yangtze River Delta, China. We further conducted variation partitioning analysis random discern dominant factor driving plant uptake. Our results indicated that T. distichum mainly absorbed shallow layers (0–40 cm, 43.63%–74.70%), while percentage deep was lower Delta (60–100 13.43%–35.90%), whether light, moderate, or heavy conditions. Furthermore, our demonstrated traits, such as fine root biomass, are dominantly These findings imply could increase soils changing their attributes, which would effectively improve forests
