Short summary
According to this study, Artemisia ordosica escaped water limitations by invoking a water-conservation strategy with the regulation of stomatal conductance and advancement of sap-flow peaking time, manifesting in a hysteresis effect. This study provides a significant contribution to the understanding of acclimation processes in desert-shrub species to drought-associated stress in dryland ecosystems.
