Response of stomatal conductance (gs; blue dots and lines) during plant dehydration and vulnerability curves expressed as percentage loss of hydraulic conductivity (PLC, red lines) as a function of water potential (MPa) for the four species measured in this study: (A) C. sempervirens, (B) J. communis, (C) T. distichum and, (D) T. articulata. Shaded bands represent standard errors at ฮจ50. Note that the Pammenter model was first fitted per sample before calculating a mean ฮจ50 and slope per species.
