Fig. 4: Oceanographic features associated with Prochlorococcus siderophore consumers.
Environmental variables (heatmap left) are colored by variable type and ordered (heatmap right) by their rank contribution to predicting the distribution of Prochlorococcus siderophore consumers (see methods). Top barplot shows the informative principal components derived from the combined dataset and ranked by their importance (unitless) to the random forest model. The lower barplot shows the variance explained (%) by each of the informative principal components. Heatmap color shows the correlation (R2) between each variable and each informative principal component.
