FIGURE 6.
Dot plot of the correlation matrix obtained by applying a Pearson analysis to the total archaeal 16S rRNA gene reads (copies L-1) of the archaeal groups and to the abundances of the archaeal IPLs (response units per Liter; r.u. L-1) detected at the (A) coastal and (B) open ocean stations of the ETSP. Dark blue corresponds to +1 r-values, indicating a strong positive linear correlation between archaeal groups and IPLs; white corresponds to 0 r-values, indicating that no correlation exists; dark red corresponds to –1 r-values, indicating a strong negative linear correlation.
