     25Based on a reanalysis of data from 36 species, Kattge and Knorr propose a parametrization where Jmax and Vcmax at 25°C are defined jointly thanks to a Jmax:Vcmax ratio. Based on their analysis, they found that the Jmax:Vcmax ration varies with growth temperature (= last month temperature). The entropy term in the temperature function of the temperature dependance to
