Fig. 4: Heatmap of the most important predictors for the vvhA gene copy number, derived V. vulnificus abundance, and the eutrophication index.

Predictors are ordered from high (left) to low (right) importance for the respective models. Observations are ordered according to decreasing vvhA gene copy numbers. Values of each predictor are scaled from 0 to 1 for color representation in the heatmap, while the original values are printed in each cell.
