Table 1.

Results from linear mixed-effects models for treatment effects on soil detritivore feeding activity. The denominator degrees of freedom are based on the Satterthwaite approximation. Variance and standard deviations (in brackets) are given for the random effects used in models (see methods for details). Bold F-values are statistically significant (***: p<0.001, **: p<0.01, *: p<0.05.)
