Sürgü Çayı (Malatya, Türkiye)’nda Makrobentik Omurgasızların Tür Kompozisyonu ve Çeşitliliği

Abstract

The study was carried out on Sürgü Stream, located in Malatya Province (Turkey), and aimed to determine the diversity and species composition of macrobenthic invertebrates. Six stations were determined on the stream and macrobenthic invertebrates were taken seasonally. As a result, 34 taxa belonging to five classes were detected; one of which belongs to Hirudinea, one of which belong to Arachnida, three to Gastropoda, five to Malacostraca and 24 to Insecta classes. Insecta was the most dominant group among the determined taxa. The Shannon Weaver Diversity Index and the Simpson Index showed that the lowest species diversity was observed at the third station while the highest species diversity was found at the second station. Also, UPGMA algorithm was used to show possible clustering relationships among the seven stations based on organisms. According to UPGMA analysis, the highest similarity value was observed between the first and second stations (87%), while the lowest similarity value was found between the second and fourth stations (13%). To date, there is no study on the determination of macrobenthic invertebrate fauna of Sürgü Stream. Therefore, all the identified taxa have been recorded for the first time for the study area.

“…In Turkey, the biotic index studies began with a work in Sakarya and Seyhan catchment areas by Government Water Works in 1992 (DSI, 1992). On this field, the studies have importantly accelerated since 1992 (Kazancı and Dügel, 2000;Kazancı et al, 2003;Duran et al, 2003;Balık et al 2006;Sukatar et al, 2006;Kazancı and Dügel, 2008;Kazancı et al, 2009;Kazancı, 2009;Kazancı et al, 2010b;Türkmen and Kazancı, 2010a;Türkmen and Kazancı, 2010b;Yıldız et al, 2010;Türkmen and Kazancı, 2011;Topkara et al, 2011;Zeybek et al, 2014;Yıldız et al 2015;Yorulmaz et al, 2015;Başören and Kazancı, 2016;Zeybek, 2017;Özbek et al 2019;Tüzün Tereshenko, 2019;Koşal Şahin and Zeybek, 2019). One of these indices used in monitoring studies is the BMWP (Biological Monitoring Working Party) index that was established in 1976 to determine the biological quality of water by family identification of aquatic invertebrates collected from rivers in the UK and Scotland.…”
