Average training and test receiver operating characteristic curve (AUC) and average point biserial correlation (COR) (±95% confidence interval) among the ten replicates for each focal species habitat suitability model used for our 2011 sampling location stratification in the Sonoran Desert of Arizo

Number in parenthesis after each species  =  number of occurrence records in the Maxent model input. Model numbers referred to variables that included: 1) topography, spectral bands, NDVI, and precipitation data; 2) topography, spectral bands, NDVI, precipitation layers, and road distance; 3) topography, spectral bands, NDVI, and road distance; 4) topography, spectral bands, NDVI, and winter or summer (for Pennisetum) precipitation; and 5) topography, spectral bands, NDVI, winter or summer (for Pennisetum) precipitation, and road distance. **  = p<0.01, ***  = p<0.0001.
