Data matrix with freshwater fish species, origin, status and occurrence at studied basins.

The information is shown in brackets according to presence/absence (1 and 0, respectively) in historical, current, and future assemblages. For native and naturalized species, brackets were ordered as: [historical presence, current presence, presence in ‘Future 1’ assemblage], presence in assemblage ‘Future 2’, presence in ‘Future 3’ assemblage]. For exotic species potentially successful colonizers to the Chilean basins, the information was ordered as: [historical, current, presence in ‘Future 4’ assemblage, presence in ‘Future 5’ assemblage, presence in ‘Future 6’ assemblage]. By using this information other nine assemblages were conformed. (XLSX)
