The effect of using different temperature ranges, according to MAT differences along an elevation gradient, to calculate Q ₁₀ values for bacterial growth. (a) Q ₁₀ calculated using T _min from Figure 2a in the range 5–15°C and 15–25°C. (b) Standardized Q ₁₀ (10–20°C) calculated using T _min from Figure 2a, compared with in situ specific Q ₁₀ (MAT ±5°C; Y = 5.2–0.21X + 0.0033X ², R ² = 0.92). The thin line at a value of 2 for Q ₁₀ indicates an approximately upper limit for Q ₁₀ for most enzyme activities (V _max) for these sites (Nottingham et al., 2016). (c) Predicted increases in growth with a 2°C increase in MAT calculated using T _min from Figure 2a. “No adaptation” was calculated using Equation ([Link]), while “adaptation” was calculated assuming a 0.6°C increase in T _min
