摘要: The bluespotted cornetfish (Fistularia commersonii) (Osteichtyes, Fistulariidae) is considered to be one of the most invasive species Mediterranean Sea and Europe but only scattered information exists on its distribution abundance. Here we collated available records, following first detection in Sea, January 2000, until October 2011. A total 191 observations were used reconstruct invasion sequence, provide estimates rate spread construct an environmental suitability model based six biophysical variables maximum entropy approach. results showed that colonization proceeded parallel along southern northern rim Basin at speeds reached 1,000–1,500 km year−1 with a clear decrease Sicily Strait. important explanatory for describing F. commersonii mean depth (explaining 32.4 % data variance), chlorophyll-a (29.3 %), salinity (18.4 %). Coastal areas relatively low concentrations high preferred habitat invaded range. Conversely, extreme productivity (highly eutrophic or highly oligotrophic), cold temperatures provided abiotic resistance this invasion. Areas identified coasts Levantine Dodecanese, Strait Tyrrhenian Sea. In contrast, north Aegean Adriatic Alboran Nile Delta, western Egypt Cyrenaica unfavourable Despite some limits due model’s resolution scale, these general predictions new insights into invasion, indicating factors primary importance shaping
