Alpha-diversity indices in BML, BCR, and MLSB surface waters on shared sample dates, based on 18S rRNA gene sequencing at the ASV level, normalized to 1000 counts and filtered to include only phytoplankton. The 18S rRNA gene was chosen because it had the most shared sample points. Data points in the left panels are means of three samples ± 1 SEM, except for MLSB samples, which were unreplicated. Stem-and-leaf plots (right panels) for each index indicate means, 95% confidence intervals, and ranges averaged by site over all sampling dates; points indicate outliers. Diversity indices were significantly different across sites in all cases except in BML versus MLSB for the Shannon diversity index
