ترجمة الملخص

Phytoplankton biodiversity is the basis of the functioning of the aquatic ecosystems. Also,understanding and evaluating the effects of the change in our environment and their impacton planktonic populations is an important element. In fact, this paper was to appreciate thediversity and composition of phytoplankton in relation to some physicochemical parameters.Water samples were collected along the Algerian coastline (Alboran Sea, the Algerianbasin and the Middle area), during the period May-June 2013. The study area contained adiversified phytoplankton community (296 species), belonging to 138 genera. The algalgroups were represented and classified as dinoflagellates (180 species), diatoms (103species), cyanophyceae, coccolithophorids, euglenids, and chrysophytes (13 species). Thespatial distribution of cell densities revealed a heterogeneous phytoplankton compositiondominated by dinoflagellates, which represent 63% of the total abundance, followed by diatoms(35%). Quantitatively, we observed a highest cell density and diatoms abundance inmost stations of the Alboran Sea decreasing towards the east (Algerian basin). The peak ofdinoflagellates in June was represented by Prorocentrum and Gymnodinium genera.
