İzmir Körfezi'nin mikroplanktonunda meydana gelen değişimlerde ortam faktörlerinin rolü

144a VI- ABSTRACT At the end of this investigation about ecology and dynamics of nanoplankton and one-celled microplankton İn Izmir Bay, 103 Diatoroophyceae, 3 Silieoflagellata, 1 Euglenophyceae, 111 Dinoflagellata, I Ebriida, 1 Radiolaria and 47 Tintinnida (Ciliata) members (including varietes) were determined. The qualitative and quantitative analyses indicated that the oligotrophic Aegean water masses were active in the west of the Güzelyalı-Eski Gediz Ağzı line and the eutrophic Inner Bay water masses were mixed in the oligotrophic water periodically at the east of the line, and this event caused the blooms of the phytoplanktonic species.

R. setigera and.T. rotula were the most important blooming species in the Inner Bay and the dinoflagellates like G. tamarensis. P. steini and P. micans which were tolerant at high levels of nutrients were active during the investigation period at the harbour region.

Türkiye denizleri fitoplankton türleri kontrol listesi

Güney Karadeniz, Marmara Denizi, doğu Ege Denizi ve kuzey doğu Akdeniz'in Türkiye kıyılarında (yaklaşık 36° 00' 00"- 42° 00' 00" enlemler ve 26° 00' 00" - 45° 00 ' 00" boylamlar arası) yapılan lokal fitoplankton araştırmaları bir kontrol listesi hazırlamak için bir "araya getirildi. Bölgede yirminci yüzyılın ikinci yansında başlayan araştırmalardan toplam 7 prokaryot ve 485 eukaryot taksa listelendi. Dinoflagellat Gonyaulax tamarensis (<=Alexandrium tamarense) Gymnodinium cf. mikimitoi (=Karenia mikimitoi), diyatom Nitzschia şeriata (=Pseudonitzschia şeriata) and Heterosigma cf. akashiwo birkaç araştırmacı taraflndan rapor edilmesine rağmen, bu türler, üzerlerine yetersiz lokal sistematik veri bulunması nedeni ile geçerli kabul edilmediler
