Bar Plot from Scientific Research

Variable importance in the random forest model including all benthic, fish, microbial, and water chemistry variables. Purple bars indicate variables with p-value < 0.05 in the permutation test, while gray bars indicate p-values > 0.05. Stars indicate the p-values in the random forest permutation test (*** p-value < 0.001, ** p-value < 0.01, * p-value < 0.05). Light purple indicates variables removed by the conditional random forests
