Non-metric multi-dimensional scaling ordination (NMDS) plots in BML, BCR, and MLSB surface waters based on Bray–Curtis dissimilarities of phytoplankton communities. Data were normalized using scaling with ranked subsampling (SRS) [41] to 4000, 1000, 100, and 10,000 for the 23S, 18S, and 16S rRNA gene and cell count datasets, respectively. Taxa were classified at the ASV-level for molecular data and at the species-level for cell count data. k = 2 axes for all plots. Stress scores were 0.198, 0.207, 0.142, and 0.239 for the 23S, 18S, and 16S rRNA gene and cell count datasets, respectively. Clusters with ANOSIM support are indicated by coloured circles; all samples were included in ANOSIM analysis, but circles were hand-drawn to emphasize clustering (See Additional file 2: Table S15). Winter samples were not included in this analysis as there was no winter sampling for BCR
