The purpose of this study is to determine the macrobentic marine flora of Northeastern Mediterranean (Gazipasa-Iskenderun) shores. Seasonal samples of the shore macroflora were taken from the eight stations selected along the coast. The samples were collected a depth of 12 m from five; 25 m from two and 40 m from one of the stations. The effect of flora distributies was studied in four of the stations. A total of 42 species were determined, 20 species belonging to Rhodophyta, 13 species belonging to Phaeophyta, 8 species belonging to Chlorophyta, and 1 species belonging to Spermatophyta. Maximum species diversity was found at stations seven. P. oceanica (L.) Delile populations, which is an endemic species of Turkish Mediterranean coasts, found to be changed under the stres beacuse lessepsian species and pollution.

Bu çaly?mada, Kuzeydo?u Akdeniz kyyylary (Gazipa?a–Yskenderun) makrobentik deniz florasynyn belirlenmesi amaçlanmy?tyr. Çaly?ma, sekiz istasyonda mevsimsel örneklemelerle yürütülmü?tür. Ystasyonlaryn be?inde 12, ikisinde 25 ve birinde 40 m derinlikler temel alynarak derinli?in makrobentik flora da?ylymyna olan etkileri de ara?tyrylmy?tyr. Çaly?ma sonunda Rhodophyta'dan 20, Phaeophyta'dan 13, Chlorophyta'dan 8 ve Spermatophyta dan 1 olmak üzere toplam 42 türün bölgede da?ylym gösterdi?i tespit edilmi?tir. Maksimum tür çe?itlili?i 7. istasyonda bulunmu?tur. Akdeniz'in endemik türü olan P. Oceanica (L.) Delile populasyonlarynyn bazy lesepsiyen türler ve kirlilik gibi nedenlerle giderek bozuldu?u tespit edilmi?tir.
