Modern Dinoflagellate Cyst Assemblages of Aliağa and Nemrut Bay: Influence of Industrial Pollution
Aliağa ve Nemrut Körfezi'nde (Doğu Akdeniz) endüstriyel kirlilik ve sediment karakteristiklerinin etkisini anlayabilmek amacı ile modern dinoflagellat kistlerinin uzamsal dağılımı çalışıldı. Sekiz yüzey sediment örneği endüstriyel kirlilik içeren bu alanlardan toplanarak dinoflagellat kistlerin uzamsal dağılımları analiz edildi. Örnekleme noktalarında toplam 42 dinoflagellat kist morfotipi belirlendi ve toplam kist bolluğu 11 ile 2543 kist g-1 kuru sediment ağırlığı olarak bulundu. Kist topluluğu Gymnodinium nolleri, Alexandrium affine tip ve Lingulodinium machaerophorum tarafından temsil edildi. Aliağa Körfezi istasyonlarında kist konsantrasyonu daha yüksek iken Nemrut Körfezi istasyonlarında kist çeşitliliği daha yüksek kaydedildi. Toplam kist konsantrasyonu ve ototrofik kist konsantrasyonu örnekleme alanında metal kirliliğini işaret etmesine rağmen toplam kist sayısı Cr hariç herhangi bir metalle bağlantılı değildir. Bununla birlikte dinoflagellat kist dağılımının Aliağa ve Nemrut Körfezi sediment yapısı ile ilişkili olduğu gözlenmiştir
Endüstriyel Kirliliğin Etkisindeki Aliağa ve Nemrut Körfezi Modern Dinoflagellat Kist Topluluğu
The spatial distribution of modern dinoflagellate cysts was studied, with the purpose of understanding the impact from industrial pollution and sediment characteristics. Eight surface sediment samples were collected to analysis of the spatial distribution of dinoflagellate cysts from two industrially polluted areas: Aliağa and Nemrut Bay (Eastern Mediterranean). A total of 42 dinoflagellate cyst morphotype were identified and total cyst abundance ranged between 11 and 2543 cyst g-1 dry weight sediment at sampling points. The cyst assemblages were represented by cyst of Gymnodinium nolleri, Alexandrium affine type and Lingulodiniumma chaerophorum. The higher cyst concentration was recorded at mostly Aliağa Bay stations however the higher cyst diversity was found at Nemrut Bay stations. Total cyst concentration and autotrophic cyst concentration indicated metal pollution in the sampling areas whereas total number of cysts had no correlation with any metal levels in the sediment except Cr. The distribution of dinoflagellate cysts also showed correlation with sediment structure in Aliağa and Nemrut Bay
