Extended Data Fig. 1: An example of the response of Amax,2000 to \(\overline{{T}_{\boldsymbol{air}}}\), Tair, and fAPAR under a fAPAR-Tair bin pair.
From: Evidence for widespread thermal acclimation of canopy photosynthesis
Cross-site Amax,2000, \(\overline{{T}_{{air}}}\), Tair, and fAPAR samples are collected when 0.56 < fAPAR ≤ 0.58 and 15 °C < Tair ≤ 16 °C. a–c, Relationships between Amax,2000 and \(\overline{{T}_{{air}}}\) (a), Amax,2000 and Tair (b), and Amax,2000 and fAPAR (c). The black lines represent the best fits between Amax,2000 and \(\overline{{T}_{{air}}}\) as a linear mixed-effect function (Amax,2000 ∼ \(\overline{{T}_{{air}}}\) + (1∣Site), two-sided test, P < 0.001) (a), Amax,2000 and Tair as a linear function (Amax,2000 ∼ Tair, two-sided test, P > 0.05) (b), and Amax,2000 and fAPAR as a linear function (Amax,2000 ∼ fAPAR, two-sided test, P > 0.05) (c).
