Ceratium hirundinella Kist ve Vejetatif Hücrelerinin İki Baraj Gölünde Dağılım Dinamikleri, Türkiye

Ceratium hirundinella (O.F.Müller) Dujardin vejetatif hücreleri ve kistlerinin mevsimsel değişimleri ile vertikal ve horizontal dağılımları Ağustos 2010 ve Temmuz 2011 tarihleri arasında Erfelek ve Dodurga Baraj Gölleri’nde (Sinop, Türkiye) çalışılmıştır. Sonuçlar fitoplanktonda kist formunun vejetatif hücreler ile birlikte bulunduğunu göstermiştir. Ceratium hirundinella sonbahar/kış dönemlerinde yüksek sayılarda kaydedilmiştir. Kış şartlarının türün varlığı/yokluğu üzerine etki etmediği, ancak hücre yoğunluğunu etkilediği gözlenmiştir. Her iki baraj gölünde de horizontal olarak vejetatif hücreler çoğunlukla lakustrin ve geçiş zonlarında gözlenmiş, vertikal olarak ise kist formu Erfelek Baraj Gölü’nde kaydedilmiş ancak Dodurga Baraj Gölü’nde tespit edilmemiştir. Çözünmüş oksijenin vejetatif hücrelerle pozitif yönde korelasyon gösterdiği, pH, iletkenlik ve redoks potansiyelinin ise vejetatif hücreler ve kist oluşumu için önemli faktörler olduğu tespit edilmiştir.

Distribution Dynamics of Vegetative Cells and Cyst of Ceratium hirundinella in Two Reservoirs, Turkey

The seasonal variation and vertical and horizontal distributions of Ceratium hirundinella (O.F.Müller) Dujardin and occurrence of its cyst form in Erfelek and Dodurga Reservoirs (Sinop, Turkey) were studied between August 2010 and July 2011. Our results showed that cyst form was observed with vegetative cells in phytoplankton. Ceratium hirundinella was recorded in high numbers in autumn/winter periods in these reservoirs. Winter conditions did not affect presence/absence of the species, but influenced the cell densities. Vegetative cells were observed mostly in lacustrine and transition zones, horizontally in two reservoirs and also cyst form was recorded in Erfelek Reservoir but not found in Dodurga Reservoir vertically. Dissolved oxygen had positive correlation with vegetative cells and also pH, conductivity and redox potential were important factors for vegetative cells and cyst occurrence.
