Limiting environmental factors on predicted probability for A. palmeri. The map depicts which environmental factor in the Maxent models contributes most negatively to the predicted probability of occurrence in each raster cell. The panels mirror the maps in the previous figure. Panels A and B are CliMond variables, panels C and D are PRISM variables, panels A and C are for models built with the native + invaded dataset and panels B and D are for models built with the invasive only dataset. Maps show are representative of the limiting factors by geographic region for the 25 models in the results.
