Abstract

In this study, a diatom increase in the phytoplankton community in the north-east part of Sea of Marmara was observed in winter (upper layer water temperature between 7-9°C and salinity between 22-24 psu). In the water samples were determined a total of 45 phytoplankton taxa from the four algae classes. Most of these taxa (94 %) were composed of dinoflagellates and diatoms and other organisms parts were silicoflagellates and euglenoid flagellate species. The most common species from diatoms were Proboscia alata f. alata (Brightwell) Sundström, from dinoflagellates Ceratium fusus (Ehrenberg) Dujardin. The diatom Proboscia alata f. alata was quantitatively the dominant species in the phytoplankton community. The highest cell density was measured about 185 x 103 cells I"1. It is noticeable that diatoms were more dominant than other phytoplankton species.

Özet

Bu çalışmada kuzeydoğu Marmara Denizi fıtoplankton kommunitesinde kış mevsiminde (üst tabaka su sıcaklığı 7-9°C, tuzluluk 22-24 psu arasında) gözlenen bir diyatom artışı açıklanmaktadır. Bu amaçla örnekleme alanından alınan tüm örneklerde dört alg sınıfından toplam 49 phytoplankton taksonu belirlenmiştir. Bu taksonların büyük çoğunluğunu (%94) dinoflagellat ve diyatomlar oluştururken diğerleri ise silikoflagellat ve öglenoid flagellat türlerinden oluşmaktadır. En sık rastlanan türler diyatomlardan Proboscia alata f. alata (Brightwell) Sundström, dinoflagellatlardan Ceratium fusus (Ehrenberg) Dujardin türleridir. Tüm çalışma alanında kantitatif olarak Proboscia alata f. alata dominant türdür. En yüksek hücre sayısı 185 x 103 hücre I"1 olarak hesaplanmıştır.. Diyatomların diğer fıtoplankton türlerine göre baskın grubu oluşturdukları gözlenmiştir.
