Abstract

Tintinnid species composition and abundance were examined seasonal at 9 stations (0.5 m, 5.0 m, 10.0 m and 15.0 m) in Izmir Bay between November 2008 and July 2010. During the study period, belonging to the class Ciliata, 17 taxa were determined. Stenosemella nivalis, Tintinnopsis cylindrica and Undella hyalina were the dominant species observed in almost all the stations. The lowest number of species was found in April 2009 with 3 species whereas the highest number of species was determined in March 2010 with 12 species. The minimum and the maximum cell density of the class Ciliata were observed in April 2009 (0.039x103 cell lt-1), and July 2010 (152x103 cell lt-1) respectively. In this period, the species with respect to the high cell density were Helicostomella subulata, Salpingella decurtata and Steenstrupiella steenstrupii. These three species reached their maximum cell densities in the stations located in the inner bay where the environment was under the influence of domestic and industrial wastewaters. The Shannon-Wiener diversity index values varied between 0.032 (Station 22) and 2.165 (Station 20). Additionally, a negative relationship was determined between tintinnid and phytoplankton abundance.

Özet

İzmir Körfezi'nde Ciliata tür komposizyonu ve bolluğu Kasım 2008 ile Temmuz 2010 tarihleri arasında 9 istasyonda (0.5 m, 5.0 m, 10.0 m ve 15.0 m) mevsimsel olarak incelenmiştir. Yapılan çalışmalar sonucunda Ciliata sınıfına ait toplam 17 taksa saptanmıştır. Stenosemella nivalis, Tintinnopsis cylindrica ve Undella hyalina hemen hemen tüm istasyonlarda gözlenen baskın türlerdir. Çalışmada en düşük tür sayısı 3 tür ile Nisan 2009 döneminde, en yüksek tür sayısı ise 12 tür ile Mart 2010 döneminde saptanmıştır. Ciliata sınıfındaki en düşük hücre yoğunluğu Nisan 2009 döneminde (0.039x103 hücre lt-1), en yüksek hücre yoğunluğu Temmuz 2010 döneminde (152x103 hücre lt-1) gözlenmiştir. Bu dönemde, yüksek hücre yoğunluğuna neden olan türler Helicostomella subulata, Salpingella decurtata ve Steenstrupiella steenstrupii' dir. Bu üç tür de evsel ve endüstriyel atıksuların etkisi altında bulunan iç körfez istasyonlarında en yüksek hücre yoğunluğuna ulaşmışlardır. Shannon- Wiener çeşitlilik indeks değeri 0.032-2.165 bits arasında değişmekte, en düşük çeşitlilik indeks değeri ise 22 nolu istasyonda, en yüksek çeşitlilik indeks değeri ise 20 nolu istasyonda saptanmıştır. Ayrıca yapılan çalışmada tintinnid bolluğunun fitoplankton bolluğu ile negatif yönlü bir ilişki gösterdiği saptanmıştır.
