Extended Data Fig. 2: The relationships between canopy photosynthetic capacities and \(\overline{{T}_{\boldsymbol{air}}}\) over fAPAR and Tair bins.
From: Evidence for widespread thermal acclimation of canopy photosynthesis
a, The partial effect of \(\overline{{T}_{{air}}}\) on Amax,2000 when \(\overline{{PPFD}}\) is also incorporated in the modelling (Amax,2000 ∼ \(\overline{{T}_{{air}}}\) + \(\overline{{PPFD}}\) + (1∣Site)). b, Partial correlation coefficients (partial r) between Amax,2000 and \(\overline{{T}_{{air}}}\) when controlling for \(\overline{{PPFD}}\) (Amax,2000 ∼ \(\overline{{T}_{{air}}}\)∣\(\overline{{PPFD}}\)). c, The cross-site thermal acclimation rate (\({\gamma }_{{\rm{T}}}\)) is calculated based on Amax (Amax ∼ \(\overline{{T}_{{air}}}\) + (1∣Site)). d, The cross-site \({\gamma }_{{\rm{T}}}\) is calculated using plant function types (PFTs) as random intercepts (Amax,2000 ∼ \(\overline{{T}_{{air}}}\) + (1∣PFT)). Numbers (%) in parentheses represent the detectability of positive \({\gamma }_{T}\) values, which is defined as the percentage of the number of bins displaying a positive \({\gamma }_{{\rm{T}}}\) over the total number of bins. Black dots indicate significant (P < 0.05) correlations.
