摘要：Many of the Indo-Pacificoriginated marine alien species are accepted to be introduced to the Eastern Mediterraneanfrom Red Sea after the opening of Suez Canal and then dispersed towards theWestern Mediterranean, as well as the Aegean Sea. However, alien foraminiferspecies, such as Spiroloculinaantillarum, Coscinospira hemprichii, Peneroplis pertusus, P. planatus, Soritesorbiculus, Astacolus insolithus, Siphonina tubulosa, Amphistegina lessonii andA. lobifera have been found in thesediments from southeastern Turkey, which dated much before the Suez Canal. InAkkuyu (Mersin) Amphistegina lobiferawere found to be abundant in sediment samples and the OSL (thermolunisence)method surprisingly revealed ages, 227.3±17.8 (Middle Pleistocene), 87.7±9.6(Late Pleistocene) and 6.0±0.6 (Holocene) thousand years before present. Thisfinding suggests that some alien foraminifers might have entered the EasternMediterranean, not from Suez Canal, but through the Red Sea-Gulf of Aqaba-DeadSea Fault line and Arabian Gulf-Mesopotamia Basin. As a result, the historicalpathways, other than Suez Canal should be taken into consideration whendefining the mode of introduction for Indo-Pacific originated alien speciesfound in the Mediterranean.
