Dry meadow. Effect of treatment (mowing), year, season (June, October) and site on biomass and TNC storage properties of meadow plants (PERMANOVA). Block is a random factor; year, season, treatment and species are fixed factors. F-values are shown for significant (or marginally significant) results; †0.05 < P < 0.1; *0.01 < P < 0.05; **P < 0.01; n.s., non-significant P ≥ 0.1; df, numerator/denominator degree of freedom; all dependent variables were log-transformed. Significant F-values (i.e. P < 0.05) are in bold.
