Table S1. A. Faunal assemblage analysis. PERMANOVA for abundance of macrofauna as response to the fixed factors Trawling intensity (quartiles <= 0.4, > 0.4 <= 2.1, > 2.1 <= 4.6, > 4.6), Year (2009, 2010, 2011, 2014), and Sampling station as random factor nested in Trawling intensity. B. Post-hoc comparison by pairwise PERMANOVA of Trawling intensity. Dependent variable was transformed by fourth root. Distance based test for homogeneity of multivariate dispersions (PERMDISP) did not indicate deviation from homogeneity (Group factor Year: F = 1.02, df1 = 3, df2 = 228, p = 0.42 Group factor Trawling intensity: F = 1.77, df1 = 3, df2 = 228, p = 0.181).
