Comparison of the average temperature dependence of primary succession on Mauna Loa (ml; ε = 1.8) (Table 1) with the rates typically observed for some of the constituent processes: nitrogen fixation by S. vulcani (n; Ea ≈ 0.95 eV), basalt weathering (w; Ea ≈ 0.4–0.5 eV), aerobic respiration rates (r; Ea ≈ 0.65 eV), and photosynthesis (p; Ea ≈ 0.3 eV). For display purposes, values are rescaled to normalize the rates to 1 at 7°C.
