Analysis of metagenomic reads assigned as nifH obtained from the In situ chemotaxis assay. A Boxplot showing the range and median of the effective number of species calculated for each independent sample replicate. Significance levels reported in A is the difference between FSW and Bulk seawater and phytoplankton treatments (**p < 0.01; ***p < 0.001; n = 4; ANOVA (one-sided)). B Principal coordinate analysis (PCO) of Bray-Curtis similarity. Bulk (Bulk seawater), FSW (Filtered seawater); dotted line represents 60% similarity. C The relative abundance of classified metagenomic reads assigned as nifH combined for the four biological replicates. Blues: Cluster I, Green: Cluster I Cyanobacteria, Yellow, reds, and black: Cluster III, and Gray: Others. B, C are based on averaged relative abundances of four biological replicates.
