Bivalves are among the main groups of invasive freshwater species, with the Asian clam genus Corbicula in particular being widely distributed. While global studies have focused on Corbicula fluminea (Müller, 1774), the invasive potential of Corbicula largillierti (Philippi, 1844) and Corbicula fluminalis (Müller, 1774) is still unknown. The spread of invasive species may be intensified by climate change. We estimated and compared environmentally suitable areas for these species under hypothetical climate scenarios, generating global maps of invasion risk. We found large climatically suitable areas for C. largillierti and C. fluminalis (under species distribution models) and that their invasive potential is currently underestimated. The analysis revealed many areas in which changing climate may favour the invasion of Corbicula spp.
