Abstract

In the present study, aquatic Oligochaeta (Annelida: Clitellata) fauna and environmental parameters from 15 predetermined stations in Sarıçay, Karamenderes, Tuzla, and Kocabaş streams in Biga Peninsula (NorthWest Anatolia) were seasonally studied. Benthic samplings were collected via Hess Sampler and Ekman Birge Grab. During benthic samplings, temperature, electrical conductivity, pH, and dissolved oxygen were analysed on-site whereas chemical oxygen demand (COD), biological oxygen demand (BOD5), and water quality parameters such as PO4-P, and NO3-N were analysed in laboratory. In this study, a total of 340.993 individuals of Oligochaeta belonging 33 different taxawere obtained. The family Naididae had the highest number of species (29 taxa); and followed by Enchytraeidae (2 taxa) and Lumbriculidae (2 taxa).It was demonstrated through Multidimensional Scaling (MDS) that species that are tolerant to organic pollution, including Potamothrix hammoniensis (Michaelsen, 1901), Tubifex tubifex Müller, 1774, Limnodrilus hoffmeisteri Claparede, 1862 are dominant in the stations located in sub tributary basins. In addition, Bothrioneurum vejdovskyanum Stolc, 1886, Mesenchytraeus sanguineus Nielsen & Christensen, 1959 and Enchytraeus christenseni Dozsa-Farkas, 1992, found in this study, are recorded for the first time for the aquatic Oligochaeta Fauna in Turkey.

Özet

Bu çalışmada, Biga Yarımadası akarsularından Sarıçay, Karamenderes, Tuzla ve Kocabaş’ta belirlenmiş 15 örnekleme istasyonunda, Oligochaeta (Annelida: Clitellata) faunası çevresel değişkenler ile birlikte mevsimsel olarak araştırılmıştır. Bentik örneklemeler Hess Sampler ve Ekman Birge Grab ile gerçekleştirilmiş ve örnekler kantitatif olarak değerlendirilmiştir. Bentik örneklemeler sırasında, su sıcaklığı (T), elektrik iletkenliği (EC), pH ve çözünmüş oksijen (DO) yerinde, kimyasal oksijen ihtiyacı (COD), biyolojik oksijen ihtiyacı (BOD5), PO4-P, NO3-N gibi su kalitesi laboratuvarda analiz edilmiştir. Araştırma sonucunda, Naididae familyasından 29 taksa, Enchytraeidae 2 taksa ve Lumbriculidae 2 taksa olmak üzere 33 taksaya ait toplam 340993 birey tespit edilmiştir. Organik kirliliğe toleranslı Potamothrix hammoniensis (Michaelsen, 1901), Tubifex tubifexMüller, 1774, Limnodrilus hoffmeisteri Claparede, 1862 türlerinin alt akarsu havzalarında yer alan istasyonlarda baskın olduğu MD Sanalizi ile gösterilmiştir. Ayrıca, çalışmada tespit edilen Bothrioneurum vejdovskyanum Stolc, 1886, Mesenchytraeus sanguineus Nielsen & Christensen, 1959 ve Enchytraeus christenseni Dozsa-Farkas, 1992 türleri Türkiye sucul Oligochaeta Faunası için ilk kayıt niteliğindedir.
