Chemico-physical parameters correlated with Ca. Poseidoniales genera abundances. Chemico-physical data were obtained from the TARA Ocean data set. a Normalised read abundances of the 90% quantile for each clade, grouped by chemico-physical metadata. Significant correlations between abundance of clades and chemico-physical properties are indicated by an asterisk. b Significant correlations between clades and chemo-physical properties. Positive correlations between clades and chemico-physical properties are shown in red, negative correlations in blue. Acronyms used are the following: NO3, nitrate; PO4, phosphate; Si, Silica (SiO2, silicon dioxide), picoeukaryotes, fluorescence-based count of picoeukaryotes (cells/ml); Depth, mean sampling depth (m); Temp, mean temperature °C. Correlations were assessed using a GLM model on a per-clade basis, identifying significance with a Wald test, after adjusting the p values with the Benjamini−Hochberg procedure
