“…These changes, which are taking place across many different taxa and through different regions of the globe, have significant implications for biodiversity, ecosystems, and society (McGeoch & Latombe, 2016) and are considered to be particularly apparent in the Mediterranean, a semi-enclosed sea, which is warming faster than any other marine region in the world (Schroeder, Chiggiato, Bryden, Borghini, & Ben Ismail, 2016;Vargas-Yáñez et al, 2008). In addition, maritime traffic, mariculture, aquarium trade and above all, entries through the Suez Canal (Edelist, Rilov, Golani, Carlton, & Spanier, 2013;Parravicini, Azzurro, Kulbicki, & Belmaker, 2015) contribute to the introduction of a large number of nonindigenous species (hereafter referred as NIS) to this basin (Galil, Marchini, Occhipinti-Ambrogi, & Ojaveer, 2017;Golani et al, 2018;Zenetos et al, 2017), reshaping the structure of biological communities (Albouy et al, 2013(Albouy et al, , 2015(Albouy et al, , 2014Katsanevakis et al, 2017) and impacting biodiversity and fishery resources (Edelist et al, 2013).…”
