The zooplankton species composition in the sampling site was diverse and a unique two layer flow regime of the system allowed us to observe both the Mediterranean and the Black Sea influence on the organisms.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Weekly field samplings were performed at the Kepez Harbor located at the Dardanelles Strait for temperature, salinity, Secchi disk, dissolved oxygen, chlorophyll-a and nutrient concentrations, zooplankton abundance, and community structure from 26 April 2005 to 25 April 2006.
📊
Key Findings & Data:Zooplankton samples were collected using a plankton net with a mesh size of 180 μm for the mesozooplankton and vertical tows were conducted between 0-5 m, 10-15 m, and 15-20 m.

Abstract

Weekly field samplings were performed at the Kepez Harbor located at the Dardanelles Strait for temperature, salinity, Secchi disk, dissolved oxygen, chlorophyll-a and nutrient concentrations, zooplankton abundance, and community structure from 26 April 2005 to 25 April 2006. Zooplankton samples were collected using a plankton net with a mesh size of 180 μm for the mesozooplankton and vertical tows were conducted between 0-5 m, 10-15 m, and 15-20 m. Whole water samples were also collected for microzooplankton. All mesozooplankton groups increased in number starting at the end of May through June. Copepoda dominated the surface and mixed layer during the early spring and Acartia clausi was the most abundant species when compared to the others. Cladocera showed a clear seasonal succession pattern in the study site and were mainly composed of Penilia avirostris, Pleopsis polyphemoides, and Evadne nordmanni. Oikopleura dioica, the only representative of the appendicularians, reached its maximum abundance during mid summer. The zooplankton species composition in the sampling site was diverse and a unique two layer flow regime of the system allowed us to observe both the Mediterranean and the Black Sea influence on the organisms.

Özet

Sıcaklık, tuzluluk, Secchi disk, çözünmüş oksijen, klorofil-a ve besin tuzları, zooplankton yoğunluğu ve komünite yapısının belirlenmesi için Kepez Limanı, Çanakkale Boğazı'nda 26 Nisan 2005 ve 25 Nisan 2006 tarihleri arasında haftalık örneklemeler yapılmıþtır. Mezozooplankton örneklerinin toplanması için 180 μm göz açıklığında plankton kepçesi ile 0-5 m, 10-15 m ve 15-20 m arasında dikey çekimler gerçekleştirilmiştir. Mikrozooplakton için şişe örneklemesi gerçekleştirilmiştir. Mayıs ayı sonundan baþlayarak Haziran boyunca bütün mezozooplankton grupları sayıca artmıştır. İlkbahar başlangıcında, Kopepodlar yüzey ve karışım bölgesinde baskındır ve diğer türlerle karşılaştırıldığında Acartia clausi, yoğunluğu en fazla olan tür olmuştur. Kladoserler belirgin bir mevsimsel süksesyon göstermiş ve çoğunlukla Penilia avirostris, Pleopsis polyphemoides, Evadne nordmanni ile temsil edilmiştir. Apendikülerlerin tek temsilcisi Oikopleura dioica, yaz ortasında en yüksek yoğunluğa ulaşmıştır. Örnekleme alanında zooplankton tür kompozisyonu çeşitlilik göstermiþ ve sistemin özel akış rejimi hem Akdeniz hem de Karadeniz etkisini organizmalar üzerinde görmemizi sağlamıştır.
