Ensemble models of average habitat suitability from 5 model algorithms including a generalized linear model, multivariate adaptive regression splines, boosted regression trees, random forest, and Maxent for Salvator rufescens (red tegu) trained on data in South America and applied to North America (columns). Models were produced with random and targeted background data (rows). Areas identified as having novel environmental conditions based on the Multivariate Environmental Similarity Surface are shown with a transparent gray layer. Maps use the geographic coordinate system and were built using Esri ArcGIS 10.5 (www.esri.com/sofware/arcgis).
