Fig. 5: The three-dimensional leaf trait relationships.

The relationships of log-transformed P_s (nmol g⁻¹ s⁻¹, a) and SLA (cm² g⁻¹, b) with temperature (°C) and LWC (g g⁻¹). The dots projected on the floor and walls indicate bivariate correlations. The planes represent the theoretical predicted relationships based on Eqs. (2) and (5).
