ملاحظات اولية حول المجمعات القاعية و السمكية علي الساحل السوري (منطقة اللاذقية). التنوع الحيوي المحلي و المهاجر

Within the frame of the Cultural Agreement between Lebanon and Syria, a study of biodiversity (benthos & fish) along the Lebanese-Syrian coast is currently undertaken. In the present paper which is only limited to the Syrian side, the researcher, who depend on the results of diving, points out to the distribution of the benthic animal and vegetal communities according to their appearance sequence and level of occurrence -mainly on the rocky substratum- starting from the vermetids platforms of the water surface to the bottoms where the phanerogams occur, in particular the Monocotyledon Cymodocea nodosa. The paper includes a briefing on the specific composition of the ichtyofauna that was found in the same place and highlights the local biodiversity and the migratory species (lessepsians) from the Indo-pacific to the Mediterranean, throughout the Red sea and the canal of Suez. In addition, the paper focuses on the impact of some invasive migratory species such as the brown algae Stypopodium schimperi and the red algae Galaxaura rugosa on the local species.
