Abstract

This study, accomplished is focused on the spatial and temporal distribution and species composition of phytoplankton in the southwestern Caspian Sea between January 2008 and December 2008. Samples were collected from 11 stations along three transects known as Lisar, Anzali and Sefidrood. This study identified 43 phytoplankton species comprised of diatoms (25 species), dinoflagellates (7 species), chlorophytes (6 species), cyanophytes (4 species), and euglenoids (1 species) were identified. The study showed, diatom Dactyliosolen fragilissimus and the dinofllagelate Prorocentrum cordatum numerically dominate the southwestern Caspian Sea. The annual average phytoplankton density was calculated as 2.35E+04 ± 1.63E+04 Cell L-1, with the maximum value recorded in the winter (4.50E+04 ± 3.90E+04 Cell L-1). Diatoms were dominant during the autumn and winter (77.0% and 96.0%, respectively), while dinoflagellates were prevalent during the spring and summer (89.0% and 86.0%, respectively). The annual average chlorophyll a was calculated as 9.26±3.54 μg L-1, with the maximum values were recorded in the winter (16.9±5.60 μg L-1). This is supported by the Spearman rank correlation result between phytoplankton abundance and chlorophyll a (r=0.551). The high phytoplankton cell density and chlorophyll a concentration coincided with the poor species composition.

Özet

Ocak 2008 ve Aralık 2008 arasında yapılan bu çalışma Güney Batı Hazar Denizi’nde fitoplankton’un uzaysal ve zamansal dağılımları ve tür kompozisyoları üzerine odaklanmıştır. Örnekler Lisar, Anzali and Sefidrood olarak bilinen üç kesit boyunca uzanan 11 istasyon noktasından toplandı. Diatom (25 tür), dinoflagellat (7 tür), klorofit (6 tür), cyanofit (4 tür) ve euglenoidlerden (1 tür) oluşan toplam 43 fitoplankton türü tayin edildi. Çalışma, diatom Dactyliosolen fragilissimus ve dinofllagellat Prorocentrum cordatum türlerinin sayısal olarak Güney Batı Hazar Denizini kontrol ettiğini gösterdi. Yıllık ortalama fitoplankton yoğunluğu kış döneminde kaydedilen maksimum değeriyle (4,50E+04 ± 3,90E+04 Cell L-1) 2,35E+04 ± 1,63E+04 Cell L-1 olarak hesaplandı. Dinoflagellatlar ilkbahar ve yaz döneminde (sırasıyla %89,0 ve 86,0), diatomeler sonbahar ve kış dönemi boyunca baskın grup olmuşlardır (sırasıyla 77,0% ve 96,0). Kışın kaydedilen maksimum değeriyle (16,9 ± 5,60 μg L-1), yıllık ortalama klorofil a değeri 9,26 ± 3,54 μg L-1 olarak hesaplandı. Bu durum fitoplankton bolluğu ve klorofil a arasındaki Spearman rank korelasyon sonucu (r=0,551) tarafından da desteklenmiştir. Fitoplankton biyomas ve klorofil a yüksek olduğu halde, tür çeşitliliği bakımından fakir olmuştur.
