Relationships between intrinsic temperature sensitivity indexes of (a) gross primary production rate (GPP, Q 10sG ) and (b) respiration rate (RE, Q 10sR ) vs. mean annual temperature (MAT) (GPP: Pearson’s r = −0.31, n = 403, F = 41.80, P < 0.0001; RE: r = −0.034, n = 403, F = 2.65, P = 0.49). The solid line in (a) represents the linear regression line.
