In fact, in <strong>the</strong> historical data, cold affinity elements are more important than <strong>the</strong> warm ones, while <strong>the</strong> actual list shows an opposite trend (Fig. 2), except for Chlorophyta, where both warm and coldaffinity elements increase (Tab. 1). The present work seems to confirm <strong>the</strong> popular <strong>the</strong>ory <strong>of</strong> <strong>Mediterranean</strong> Sea warming, at least for Liguria, typically one <strong>of</strong> <strong>the</strong> colder regions in <strong>the</strong> basin. Unluckily, this bulk <strong>of</strong> data, is very far to be exhaustive, both for what concerns <strong>the</strong> research <strong>of</strong> taxa to be included in <strong>the</strong> actual list, and for <strong>the</strong> taxonomical problems within <strong>the</strong> historical data. More time and energies will be necessary to achieve a representative list <strong>of</strong> Ligurian macrophytobenthos, in order to make a more accurate comparison with <strong>the</strong> o<strong>the</strong>r regions <strong>of</strong> <strong>Mediterranean</strong> Sea. ACNOWLEDGEMENTS The authors wish to thank Pr<strong>of</strong>. E. Paola and Gilles Passeron for <strong>the</strong> help on <strong>the</strong> field, Dr. E. Ballesteros and C. Rodriguez for <strong>the</strong> help with determination and Dr. R. Poggi, Director <strong>of</strong> <strong>the</strong> N.H.M. <strong>of</strong> Genoa. REFERENCES Ardissone F.
