Fig. 5: Relationship of prasinophyte ASVs to environmental variables.

Partial canonical correspondence analysis plot of prasinophyte ASVs with water column stability period as the conditioning variable, with vectors representing temperature (oC), salinity, nitrate + nitrite (μmol kg−1), and phosphate (μmol kg−1). The proportion of variation (inertia) explained by the constrained eigenvalues is indicated in parentheses for each axis. Vectors with an asterisk indicate that the variable was significantly correlated with the variation in the prasinophyte ASVs. Prasinophyte groups are indicated by color, with several important ASVs labelled by number.
