Abstract

In this study, seasonal and annual variations in seaweed species composition and biomass were examined to determine the ecological status of macroalgae around the Sinop Peninsula, Black Sea. Algal samples were collected monthly from five stations at zero to 0.5 m depth on rocky substrata with quadrat by hand during 2010. As a result of this study, a total of 30 taxa were identified, comprising 9 Chlorophyta, 8 Heterokontophyta and 13 Rhodophyta. The total highest biomas value (8515.5 g dw m ) was obtained from Hamsilos station and the lowest from Dışliman (2466.0 g dw m) and Öztürkler (2485.0 g dw m) stations, throughout the year. Based on Bray-Curtis similarity values, the stations can be classified in three groups. As a result, the highest values of biomass were found to be in the unpolluted stations, while a progressive decrease in such values was observed in stations where the effects of the anthropogenic pressure became more marked.

Changes of Macroalgae Biomass in Sinop Peninsula Coast of the Black Sea, Turkey

Abstract

Bu araştırmada, Karadeniz’in Sinop Yarımadası çevresindeki denizel makroalglerin ekolojik durumlarını belirlemek için mevcut alg türlerinin komposizyon ve biyokütlesindeki mevsimsel ve yıllık değişimler incelenmiştir. Alg örnekleri 0-0,5 m arasındaki kayalık substratumlarda beş ayrı istasyondan 2010 yılı boyunca aylık olarak kuadrat kullanılarak elle toplanmıştır. Bu araştırma sonunda, 9’u Chlorophyta, 8’i Heterokontophyta ve 13’ü Rhodophyta olmak üzere toplam 30 takson tespit edilmiştir. Bir yıl boyunca en yüksek biomas değeri 8515,5 g/mkuru ağırlık ile Hamsilos, en düşük değerler ise Dışliman (2466,0 g/m kuru ağırlık) ve Öztürkler (2485,0 g/mkuru ağırlık) istasyonlarından tespit edilmiştir. Bray-Curtis benzerlik analizine göre istasyonlar mevsimsel olarak üç ayrı grup altında toplanmıştır. Sonuç olarak, kirlenmemiş istasyonların daha yüksek biomas değerine ulaştığı, insan etkilerinin daha belirgin olarak görüldüğü yerlerde önemli düzeyde azalış gösterdiği belirlenmiştir.
