Phylogeography of the bluespotted cornetfish, Fistularia commersonii: a predictor of bioinvasion success?

摘要: Biological invasions result in huge ecological and economic impacts; therefore, a great amount of effort is dedicated to predicting the potential success newly established or candidate bioinvaders. Thus far, over 90 species fish have entered Mediterranean Sea via Suez canal, so-called Lessepsian The bluespotted cornetfish, Fistularia commersonii, remarkable its ability disperse within has been dubbed ‘the sprinter’. In just few years, starting 2000, it expanded entire area, from Canal Gibraltar. Theoretical predictions correlate dispersal capabilities an invader native range (using population genetic metrics, Fst, as proxy) with capability invading area (continuous extent spread, CES). Here, we estimated characteristics Indo-Pacific populations F. commersonii order determine if this ‘sprinter’ fits predictive model dispersal. Indeed, found that even case such very rapid expansion, predicted relationship between Fst CES fulfilled commersonii.
