Abstract

This study on epipelic algal flora and its seasonal variations in the Küçükçekmece Lagoon, Turkey was carried out between May 2001 and June 2002. A total of 116 species were identified, most of which belonged to Bacillariophyta (70 taxa). Other taxa identified included members of Cyanophyta (27), Chlorophyta (13), Euglenophyta (5) and Phaeophyta (1). Bacillariophyta were dominant in terms of species number and abundance at five stations. The seasonality of epipelic algal flora was different at all stations. Lower total cell numbers were registered at St. 5. Pennate diatoms especially Amphora spp., Navicula spp., Nitzschia spp. and Synedra spp. were dominant during the sampling period. Cluster analysis was applied to the epipelic algal community and produced two major groups reflecting the importance of seasonal variation on the epipelic algal flora.

Küçükçekmece Lagünündeki Epipelik Alg Florası

Abstract

Küçükçekmece lagünü epipelik alg florası ve mevsimsel değişimi üzerine olan bu araştırma, Mayıs 2001ve Haziran
2002 tarihleri arasında gerçekleştirilmiştir. Çoğunluğu Bacillariophyta (64 takson) divizyosuna ait olan toplam 109 tür
belirlenmiştir. Diğer taksonlar Cyanophyta (26), Chlorophyta (13), Euglenophyta (5) ve Phaeophyta (1) üylerine aittir.
Bacilllariophyta tür sayısı ve bolluğu bakımından beş istasyonda dominant olmuştur. Daha düşük organizma sayılarına 5.
istasyonda rastlanmıştır. Pennat diyatomelerden özellikle Amphora spp., Navicula spp., Nitzschia spp. ve Synedra spp.
örnekleme süresince dominant olmuştur. Kümeleme analizi epipelik alg kommunitesine uygulanmış ve epipelik alg florası
üzerine mevsimsel değişimin etkisini gösteren iki büyük grup oluşmuştur.
