Effects of warming and nutrient enrichment tested by mixed-model ANOVA with the fixed factors temperature (W) and nutrient enrichment (Nu) and the random factor day (D).

df, degrees of freedom; MS, mean square; F, F-ratio; p, p-value. Mineralizationinc is mobilization of ammonium measured in closed incubations, mineralizationflux is the sum of fluxes of ammonia, nitrate+nitrite and nitrogenous gas. P-values for significant effects of experimental treatments are shown in bold.
