Planktonik Zırhsız Dinoflagellat Ceratoperidinium falcatum (Kofoid & Swezy) Reñé&Salas, 2013 Türünün İzmir Körfezi (Ege Denizi)’ndeki İlk Üreme Kaydı

Abstract

Zırhsız dinoflagellat tür çeşitliliğinin belirlenmesi amacı ile, Haziran 2017 tarihinde İzmir Körfezi’nde belirlenen üç istasyonda örnekleme yapılmıştır. Toplanan materyalde zırhsız dinoflagellate türü olan Ceratoperidinium falcatum türü saptanmıştır. Ceratoperidinium falcatum türüne ait bolluğun 658-840 hücre L^–1 gözlendiği dönemde deniz suyu sıcaklığı 15,0 ℃, tuzluluk ise 38,6 olarak ölçülmüştür. Hücre genişliği 23,90 – 36,60 µm, uzunluğu 92,50 – 239 µm arasında değişmektedir. Bu çalışma Ceratoperidinium falcatum türünün İzmir Körfezi (Ege Denizi)’ndeki ilk üreme kaydıdır ve türün morfolojik özellikleri ile dağılımı hakkında ayrıntılı bilgi vermektedir.

First Reproduction Record of Planktonic Unarmored Dinoflagellates Ceratoperidinium falcatum (Kofoid & Swezy) Reñé & Salas, 2013 in İzmir Bay (Aegean Sea)

Abstract

With the aim of determining the species diversity of unarmoured dinoflagellates, samplings were carried out from 3 stations in İzmir Bay during June 2017. This study identified unarmoured dinoflagellat species Ceratoperidinium falcatum from the collected material. Ceratoperidinium falcatum abundance varied from 658 to 840 cells L^{– 1} during this period in sea water temperature at 15.0 ℃ and salinity of 38.6. The width of cell varies from 23.90 to 36.60 μm and the length of cell varies from 92.50 to 239 μm. This paper reports the first bloom record of the Ceratoperidinium falcatum species in the İzmir Bay (Aegean Sea) and morphological characteristics of this species were given in detail information, distrubition and original photographs.
