(a) Non-metric multidimensional scaling ordination based on Bray–Curtis dissimilarity on PLFA data, Kruskal’s stress=0.02. Open dots (dashed ellipses) and colored squares or triangles (solid ellipses) separate sediment samples taken 6 h and 46 days after organic matter modifications, respectively. Colors separate the samples according to the modification: black=algae (LowCP); gray=algae (HighCP); dark blue=algae (LowCP) with beech litter; blue=algae (HighCP) with beech litter; light blue=beech litter. Ellipses represent 95% intervals around centroids for each treatment. (b) Principal component analysis of fatty-acid profiles of sediments sampled at day 46 reveal a main shift in PLFA biomarkers for heterotrophic bacteria (i15:0) versus fungi (18:2ω6) based on POM pool quality.
