Zusammenfassung
Observational study about the arrival and the actual status of the populations of the pantropical decapod crab Cronius ruber (Lamarck, 1818) in the island of Tenerife. It is a species of the family Portunidae, whose first records in the Canary Islands were published in 2017, being cited for the first time on the coast of Tenerife in 2018. Although due to the information collected in this work, the first records of the presence of this species in Tenerife date back to 2008. It is a neocolonizer specie and a very important one because of its potential to act as an invasive species in the archipelagos of Madeira and the Canary Islands. Its arrival to the islands have been related with the intense maritime transports between the Canaries and occidental Africa. However, we cannot be ruled out a natural expansion of its populations related with the recent water warming of the Canaries, favorable to the establishment of tropical species. With this study, we aim to define the ecological niche occupied by C. ruber and to qualitative assess the degree of competition with other species of native decapods crustaceans present on the Canary littoral.
