(a) Median, IQR and amplitude for moss dry mass gain in the plugs located in the ponds A-F. The area of the plug was 9 cm2, so to estimate moss growth in g m-2 y- 1, the values of moss mass gain should be multiplied by 1111. (b) DCA for the species composition in the plugs in the ponds A-F (each of the five plugs for a pond shown as a point, species shown with their names) with mass gain as a supplementary variable. Eigenvalues: 1st axis – 0.9804, 2nd axis – 0.3359, 3rd axis – 0.0813, 4th axis – 0.0327. Supplementary variables account for 5.8% of the total variation. Sph. – Sphagnum, W. fluitans – Warnstorfia fluitans, S. exannulatum – Sarmentypnum exannulatum, S. revolvens – Scorpidium revolvens, S. scorpioides – Scorpidium scorpioides. Colours of points and boxplots represent different sampling locations (ponds).
