Ecological drivers and phylogenetic patterns of leaf minimum conductance variability in vascular plants

New Phytologist, Volume 250, Issue 6, Page 3716-3731, June 2026.
Summary Stomatal closure prevents significant water losses during drought events. Yet, leaves are not perfectly hermetic and dehydration ensues through residual water losses, known as minimum conductance (gmin), which is highly relevant since it informs on the water depletion dynamics under stress.
