Unshaded points above the bend in the slope extrapolate to RL on the y-axis. Shaded points below the breakpoint decrease at a faster rate and terminate at RD where PAR = 0 μmol/m2 per sec.|

Variables analyzed include area-, mass-, and nitrogen-based photosynthesis (Anet), dark respiration (RD), respiration in the light (RL), degree of respiratory inhibition by light (% IRL), photorespiration (PR), and carbon gain efficiency (CGE). For all variables measured or calculated, n = 7–10 for all species treatment combinations. Stars represent significance as follows: *P < 0.05, **P < 0.01, ***P < 0.001.|
