ANOVA table (F-values and significance levels) from linear mixed-effects model testing the effects of climate (C; ambient vs. future), three harvest times (H; 05-May-2021, 17-Jun-2021, and 14-Jul-2021), earthworms (Lte: with Lumbricus terrestris, Acl: with Allolobophora chlorotica), and their interactions on aboveground biomass of grass at community and species level (TotalAbove: total aboveground biomass of grass community, Fes: Festulolium, Lol: Lolium perenne, Dac: Dactylis glomerata, Poa: Poa pratense)
