^a Values of parameters where activation energies have been given can be calculated at any temperature from the following equation: $\mathrm{p}\mathrm{a}\mathrm{r}\mathrm{a}\mathrm{m}\mathrm{e}\mathrm{t}\mathrm{e}\mathrm{r}\left(25{}^{\circ }\mathrm{C}\right)\mathrm{e}\mathrm{x}\mathrm{p}\{\left(T25\right)E/[298R(273+T)]\}$, where R (8.314J K^–1 mol^–1) is the universal gas constant and T is temperature in °C.

^b Data from Boyd et al. (2015) have been refitted with the simple Arrhenius function in ^a.

^c Data from Ubierna et al. (2017) have been refitted with the simple Arrhenius function in ^a including data from 10 °C to 35 °C.
