Short Summary

This study investigates the water use strategies of self-organized shrubs in dryland ecosystems during drought periods, revealing distinct ecohydrological processes between scattered and clumped vegetation configurations.

Objective

• Investigate how root water uptake and leaf physiological traits drive water use strategies of self-organized shrubs for adapting to drought

Study Configuration

• Spatial Scale: Semi-arid Loess Plateau in China
• Temporal Scale: 2022-2024, with observations during both dry and rainy seasons

Methodology and Data

• Models used: Not specified (field observations and measurements)
• Data sources: Soil moisture sensors, morphological and root trait measurements, leaf-level physiological trait assessments, and stable isotope analysis of plant tissues (δ2H, δ18O, and δ13C)

Main Results

• Scattered shrubs primarily utilized middle and deep soil water, associated with isolated canopies that promote infiltration into deep soil layers.
• Clumped shrubs relied on shallow and middle soil water, linked to aggregated canopies and shallow roots.
• Scattered shrubs showed tight stomatal regulation with high midday leaf water potential and intrinsic water use efficiency (iWUE) during the dry season.
• Clumped shrubs exhibited relaxed stomatal regulation, with declines in midday leaf water potential and iWUE.

Contributions

• This study reveals the ecohydrological processes of self-organized vegetation in drylands and provides basis for vegetation allocation in ecological restoration.
• The findings highlight distinct water use strategies between scattered and clumped vegetation configurations, contributing to a better understanding of drought adaptation mechanisms in dryland ecosystems.

Funding
