Why Intraspecific Variance Matters

Standard models assign each species a fixed mean P50 (water potential causing 50% loss of hydraulic conductance). When drought crosses that mean, 100% of the species dies uniformly.

In natural forests, within-species physiological variance (0.35+ SD) ensures deep-rooted or cavitation-resistant individual trees survive, buffering stand biomass retention and accelerating canopy regeneration.
