Figure 8.

Time series of averaged leaf area (in m² tree⁻¹, blue dashed line) for the six monitored Pinus sylvestris saplings and simulated dynamics in percent loss in root-to-canopy conductance (PLk_rc, in %, black continuous line) according to the complete SOX+ model scheme (Hydraulic + NSL + leaf shedding). Daily leaf area is represented as the mean ± SD. Daily simulated PLk_rc is represented as the median ± 95% CI after 500 model simulation runs by sampling the posterior parameter estimate. The horizontal line indicates when k_rc = 0.5 * k_{rc, max} (PLk_rc50, dashed line), while the light gray area represents the uncertainty of when the leaf shedding rate accelerated. Because of weekly sampling campaigns, the area is relatively broad.
