Summary of the variance explained by the predictor layers ($R_x^2$) and the remaining partial correlations ($R_x^2$) for selected microbial resistant phenotypes. The complete list of independent variables and dependent included in each models and the summary for other microbial resistant phenotypes are listed in supplemental material
