Left: Relative contribution of each continental indigenous origin for non-native CONUS terrestrial gastropod species records. Right: Climatic associations of each non-native species in the indigenous range and it’s CONUS records utilizing the Köppen-Geiger climate classification scheme. Illustrations are subdivided by continent or a grouping of continents in relative proximity. Color codes are defined for each classification, and the two-letter code preceding each climate code identifies the respective region (AF = Africa, AS = Asia, CA = Central America, CB = Caribbean, EU = Europe, SA = South America, US = United States).
