Abstract

This research was carried out to determine the macrobenthic crustacean species associated with mixed eelgrass beds (Zostera marina and Z. noltii) occurring in the upper-infralittoral zone of the Sinop peninsula coast (the southern Black Sea, Turkey) and their bioecolological features. From June 2004 to April 2005, investigations were seasonally performed at the depths of 2-4 m at 6 different stations chosen on the Sinop peninsula coast. As a result of the study, a total of 7057 individuals belonging to 55 species and 6 orders were identified. Amphipoda was the dominant group in terms of number of species (63% of the total of orders) and number of individuals (83% of the total individuals). Among these, Ampelisca pseudospinimana had the highest dominance value with up to 1902 specimens (approximately 27%). However, Isopoda accounted for 47% of the total biomass. The species that have the highest individual biomass was isopod, Idotea balthica (35% of total biomass). According to a frequency index, 26 species were designated as constant, 13 species as common and 16 species as rare. The highest number of species (max. 26 species m-2) and number of individuals (2069 ind.m-2) were found at station 4 in fall and summer and the lowest at station 1 in winter (min. 6 species m-2; 8 ind. M-2).

Özet

Bu araştırma Sinop Yarımadası kıyılarının (Güney Karadeniz, Türkiye) üst infralittoral zonunda yayılış gösteren karışık deniz çayırı yataklarının (Zostera marina, Z. noltii) makrobentik krustase türlerini ve biyoekolojik özelliklerini tespit etmek amacıyla yürütülmüştür. Araştırmalar Haziran 2004-Nisan 2005 tarihleri arasında Sinop Yarımadası kıyılarından seçilen 6 farklı istasyonda 2-4 m derinliklerde mevsimsel olarak gerçekleştirilmiştir. Sonuç olarak, 6 ordoya ait toplam 55 tür ile bunlara ait 7057 birey tanımlanmıştır. Amphipoda ordosu tür (% 63) ve birey sayısı bakımından (% 83) en baskın grup olup bunlardan 1902 bireyle (% 27) Ampelisca pseudospinimana en baskın türleri oluşturmaktadır. Bununla birlikte, Isopoda toplam biyomasın % 47’sini oluşturmaktadır. Tespit edilen türler içerisinde en yüksek biyomas değeri % 35 ile Idotea balthica’ ya aittir. Frekans indeksine göre 26 tür devamlı, 13 tür yaygın ve 16 tür de seyrek olarak tanımlanmıştır. En yüksek tür (maks. 26 tür. m-2) ve birey sayısı (2069 birey.m-2) 4 nolu istasyonda sonbahar ve yaz mevsiminde, en az tür ve birey sayısı ise 1 nolu istasyonda kış mevsiminde (min. 6 tür.m-2; 8 birey.m-2) tespit edilmiştir.
