Analysis enabled the separation of the assemblages in four groups. Group A consists&amp;nbsp;of &lt;em&gt;Emiliania huxleyi&lt;/em&gt; and the subtropical species &lt;em&gt;Syracosphaera&lt;/em&gt; spp. and &lt;em&gt;Rhabdosphaera clavigera&lt;/em&gt;,&amp;nbsp;Group B is composed of &lt;em&gt;Helicospaera&lt;/em&gt; spp. and &lt;em&gt;Florisphaera profunda&lt;/em&gt;, typical species for high productivity&amp;nbsp;conditions in the middle-lower photic zone, Group C consists of &lt;em&gt;Gephyrocapsa oceanica&amp;nbsp;&lt;/em&gt;and &lt;em&gt;Braarudosphaera bigelowii&lt;/em&gt;, that characterise low salinity conditions and Group D includes&amp;nbsp;&lt;em&gt;Umbilicosphaera&lt;/em&gt; spp. and &lt;em&gt;Calcidiscus&lt;/em&gt; spp. which are described as relatively eutrophic species. The&amp;nbsp;Holocene assemblages differ distinctly from the living coccolithophore communities in the coastal&amp;nbsp;ecosystems of the Aegean Sea, where only Group A coccolithophores are thriving in the seasonally&amp;nbsp;controlled marine environment.&lt;/p&gt;</style></abstract></record></records></xml>
