00925njm 22002777a 4500 dc Gómez-Bellver, Carlos author Ibáñez Cortina, Neus author Nualart, Neus author López-Pujol, Jordi author 2020-12-17 The Cactaceae, and especially its most emblematic genus, Opuntia, is one of the groups of plants with greater invasion potential in the Iberian Peninsula. One of the most recently detected species is Opuntia aurantiaca, a small cactus with an enormous capacity of dispersion. Probably native to Argentina and Uruguay, it behaves as a very aggressive invader in Australia and South Africa. In Europe, it only occurs on the Mediterranean coast of the Iberian Peninsula (Catalonia and Valencian Community). In this study, the geographic range of the species is accurately delineated at the peninsular level. Detected firstly at the beginning of the last decade in Navajas (Castelló Province), it has been subsequently observed in other places of Castelló, but also in Valencia, Tarragona and Barcelona, and since 2017 in Girona. With all gathered occurrence data, the potential distribution of O. aurantiaca is estimated (for the current climatic conditions as well as for different scenarios of global warming). Despite the fact that the species seems to be spreading, maps of potential distribution do not forecast large expansions to other areas of the Iberian Peninsula, both for the present and for the year 2070.
