Results of repeated measures analysis of variance (RM–ANOVA), testing the effect of plant functional type removal, incl. biomass removed (co-variable) on the z-values during drought. The two different ways of testing refer to the method of calculating multifunctionality (see text in Material and methods, figure 1). n.s., non-significant.
