Model fit comparison using Akaike Information Criterion (AIC) for microarthropod community evenness as predicted by the experimental treatments. Generalized linear mixed effects models were used, with evenness (Shannon's diversity divided by the natural logarithm of species richness) as a predicted variable, and landscape (L, random factor), fragmentation (F, fixed), climate (C, fixed) and the climate–fragmentation interaction (C : F, fixed) as predictors. Analyses were run using fragmentation as a categorical variable (levels: d1, d2, d3) and as a continuous variable (log10(distance from mainland+1)).
