Appendix A. Table showing results from linear mixed-effects models including liming as a factor.

Table A1. Effects of experimental treatments and the habitat on the total and vascular plant biomass estimate, litter depth and diversity measures in linear mixed-effects models (LME). P values ≤ 0.05 are in bold and P ≤ 0.07 are in bold italics. H, Habitat; E, Exclosure; F, Fertilization; L, liming. F = 1,57 for all variables except for the habitat for which F = 1,8. All response variables except for total species richness were square root-transformed for the analysis.
