Bacillus anthracis (light blue) and Bcbva (light orange) suitability as relates to the Bcbva calibration area (orange line) using a minimum training presence threshold among the best performing models. Environments in these areas are characterized via a sample of 5000 points (right panels, same color scheme) considering four individual environmental variables (mean annual temperature, mean annual specific humidity, soil pH, and soil cation exchange capacity) and the first principal component (PC1) of the four environmental dimensions explored in this manuscript (temperature, specific humidity, vegetation greenness or NDVI, and soils). Maps were developed using shapefiles summarizing political borders of Africa from the public domain repository of Natural Earth (http://www.naturalearthdata.com/) and built with QGIS 2.18 ‘Las Palmas’.
