Kelp-associated microbial community. The microbial community was analysed in response to control (purple, ABC), glacial run-off (green, DEF) and terrestrial run-off area (orange, GHI) in Billefjorden (N = 6–9 per sampling station). DEF and GHI are ordered with increasing distance to run-off inflow (Fig. 1A; distance between sampling stations A–I on x-axis are not to scale). Different letters within plots: significances between sampling areas. (a,b) Linear trend line: visualisation of diversity indices in sampling areas. Grey area: 95% confidence interval. (a) Shannon diversity index. (b) Pielou evenness. (c) Non-metric multidimensional scaling (nMDS) ordinations showing the relative abundance of kelp-associated microbial groups in each area based on Bray-Curtis dissimilarities (stress value ≤ 0.05). (d) Heatmap showing the mean relative abundance of kelp-associated microbial community taxa (≥ 1%) in each sampling area.
