Fig. 6: Ephemeral and persistent green algal sub-species variants or ecotypes.

a Relative abundance of prasinophyte sub-species variants out of plastid amplicons in samples (symbols, also indicating depth) and stability periods (i.e., detected in only one or in multiple) across years (light to dark grey) where these ASVs were found. Sub-species variants forming ≥10% of plastid amplicons in individual samples are labelled with the ASV number with colors as in panel b. The box represents the median and interquartile range and whiskers the greatest and least non-outlier points. Singletons were excluded. b UpSet plots show ASV distributions by class or species (colors) and stability period (a black dot on the row indicating stability period means ASVs in the bar graph above detected in that period). c Venn diagram of prasinophyte ASVs in any or all stability periods showing overlap between years. d Venn diagram of prasinophyte ASVs as in panel c, but found only in the SS stability period. Note that biases in sampling frequency within a stability period can influence the observed patterns, e.g., fewer profiles were collected during AT than other periods. Note that for all panels only data from 140 m and above is used and 2016 is excluded due to incomplete sampling of the annual cycle.
