Short summary
Co-occurring tree species with varying physiologies were continuously monitored for mortality with concurrent observations of key physiological and environmental variables for a decade in a central US forest. New predictors of drought-induced mortality were developed. Time-delayed mortality was shown to be nonlinearly related to drought intensity and species’ capacities in regulating their internal hydraulic status, with elevated risk associated with extreme isohydric and anisohydric behaviors.
