RT Journal Article T1 Updating the distribution data of recently introduced freshwater fish in the Guadalquivir River Basin (Spain) A1 Sáez Gómez, Pedro A1 Prenda Marín, José AB We report new distribution data on four recently introduced species in theGuadalquivir River basin: chameleon cichlid (Australoheros facetus Jenyns, 1842),North American black bullhead (Ameiurus melas Rafinesque, 1820), Europeancatfish (Silurus glanis Linnaeus, 1758) and a minnow species of unknown origin(Phoxinus spp.). A compilation of records is used to update the distribution rangeof these species. The information collected reinforces the evidence on theestablishment and expansion of these non-native species. We recommend new fieldsampling to identify the dispersal pathways and to clarify their current statuses.
