Temperature dependence of denitrification rates at constant low dissolved oxygen levels.

<p>Denitrification rates measured in vegetated freshwater microcosms, as compared to the fitted Arrhenius equation (dotted black line; equation 1), the modelled denitrification rates (black line; equations 2–4 with parameters from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0018508#pone-0018508-t002" target="_blank">Table 2</a>), and modelled denitrification with O₂ fixed at 1 mg l⁻¹(dashed blue line; equation 2).
