Marine alien Mollusca in Italy: a criticalreview and state of the knowledge. Journal of the MarineBiological Association of the United Kingdom: 1-9.doi:10.1017/S002531541100186XThe state of the knowledge about the marine alien molluscanspecies from Italy is provided based on a critical review ofrecords comp<strong>il</strong>ed from an extensive literature survey and fromunpublished data obtained from 2005 to 2010. Based on theIUCN definition of ‘alien’, 35 molluscan taxa (18 Gastropoda,16 Bivalvia and 1 Cephalopoda) are reported here, for each ofwhich the following data (collected up to December 2010) areprovided: published and unpublished records from the coastaland offshore territorial seawaters of Italy, inclu<strong>di</strong>ng lagoons,within the 14 biogeographical sea <strong>di</strong>visions covering the Italianshores, date of first record, most plausible vector(s) of introductionand establishment status. The southern Ionian Sea,the northern Adriatic Sea and the eastern-central TyrrhenianSea resulted to be the areas most affected by alien molluscanintroductions. The rate of records of new alien species (evaluatedon the basis of live fin<strong>di</strong>ngs) is quite uniform over fivedecades, with six to eight species recorded per decade. Theanalysis of the vectors showed shipping/maritime transport tobe the most common vector of introduction (40%), followed bytrade (24%). Nineteen alien molluscan species (54%) wereconsidered as established in Italy.Nel presente lavoro si riporta lo stato dell’arte riguardole specie marine <strong>di</strong> molluschi alieni segnalate in Italia,sulla base <strong>di</strong> una revisione critica delle segnalazioni bibliografichee <strong>di</strong> dati originali raccolti dal 2005 al 2010.Sulla base della definizione <strong>di</strong> “alieno” stab<strong>il</strong>ita dall’IUCN, sono riportati 35 taxa (18 gasteropo<strong>di</strong>, 16 bivalvied 1 cefalopode), per ognuno dei quali sono forniti i seguentidati (raccolti fino a <strong>di</strong>cembre 2010): segnalazionipubblicate e non pubblicate provenienti dalle acque territorialiitaliane, incluse lagune, all’interno delle 14 <strong>di</strong>visionimarine biogeografiche; date <strong>di</strong> primo rinvenimento;plausib<strong>il</strong>i vettori <strong>di</strong> introduzione; eventuale acclimatazione.Il Mar Ionio, <strong>il</strong> Mar Adriatico settentrionale e <strong>il</strong>Mar Tirreno centro-occidentale sono risultate essere learee più affette da introduzione <strong>di</strong> specie <strong>di</strong> molluschialieni. Il tasso <strong>di</strong> rinvenimento <strong>di</strong> nuove specie aliene(valutato sulla base <strong>di</strong> rinvenimenti <strong>di</strong> esemplari viventi)si rivela abbastanza uniforme nell’arco delle ultimecinque deca<strong>di</strong>, con sei/otto specie rinvenute per decade.L’analisi dei vettori mostra come <strong>il</strong> trasporto marittimosia <strong>il</strong> vettore <strong>di</strong> introduzione più comune (40%), seguitodal commercio (24%). Diciannove molluschi alieni (54%)sono considerati stab<strong>il</strong>i nei mari italiani.Giannuzzi Savelli R., Micali P., Nofroni I. & PusateriF., 2011.
