PROCEEDINGS OF THE SECOND MEDITERRANEAN SYMPOSIUM ON MARINE VEGETATION (ATHENS, 12-13 DECEMBER 2003)<br />

Starting point <str<strong>on</strong>g>of</str<strong>on</strong>g> this work was <str<strong>on</strong>g>the</str<strong>on</strong>g> checklist <str<strong>on</strong>g>of</str<strong>on</strong>g> Italian macrophytobenthos (Furnari et al.,<br />
2003); <str<strong>on</strong>g>the</str<strong>on</strong>g> checklists <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>Mediterranean</str<strong>on</strong>g> seaweeds (Ribera et al., 1992; Gallardo et al.,<br />
1993; Gomez Garreta et al., 2001) and <str<strong>on</strong>g>the</str<strong>on</strong>g> webpage ALGABASE (Guiry, M.D. and Nic<br />
Dh<strong>on</strong>ncha E., 2003) were also c<strong>on</strong>sulted in order to assess a preliminary comparis<strong>on</strong><br />
between historical and recent data. The nomenclature and <str<strong>on</strong>g>the</str<strong>on</strong>g> chorological elements used<br />
in <str<strong>on</strong>g>the</str<strong>on</strong>g> present work follow <str<strong>on</strong>g>the</str<strong>on</strong>g> checklist <str<strong>on</strong>g>of</str<strong>on</strong>g> Italian macrophytobenthos (Furnari et al., 2003).<br />
RESULTS<br />
In <str<strong>on</strong>g>the</str<strong>on</strong>g> list obtained, representative <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> Ligurian flora from 1950 at <str<strong>on</strong>g>the</str<strong>on</strong>g> actual state <str<strong>on</strong>g>of</str<strong>on</strong>g><br />
knowledge, 243 entities (241 species and 3 varieties) are enumerated. Rhodophyta are<br />
in <str<strong>on</strong>g>the</str<strong>on</strong>g> number <str<strong>on</strong>g>of</str<strong>on</strong>g> 151, Phaeophyta 44 and Chlorophyta 48.<br />
54 <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> listed entities are inedited quotati<strong>on</strong>s for Liguria and 35 are not even reported<br />
in <str<strong>on</strong>g>the</str<strong>on</strong>g> list <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> adjacent Tuscany regi<strong>on</strong>, where phycological studies have been<br />
c<strong>on</strong>tinuous in time and 408 taxa at <str<strong>on</strong>g>the</str<strong>on</strong>g> species level have been recorded (Furnari et al.,<br />
2003). Finally 7 <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> above listed species are introduced, according to Verlaque, 1993.<br />
In <str<strong>on</strong>g>the</str<strong>on</strong>g> following list, <strong>on</strong>ly comprehensive <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> new records for Liguria (127 entities),<br />
each taxa is presented, toge<str<strong>on</strong>g>the</str<strong>on</strong>g>r with <str<strong>on</strong>g>the</str<strong>on</strong>g> following details:<br />
