Abstract

This study was carried out by the streams of Tunceli province (Turkey) between June 2008 and May 2009 to determine Mollusca fauna. Samples were taken at 20 stations, seasonally. Mollusca fauna of the streams of Tunceli was represented by three species of Prosobranchia (Bithynia pseudemmericia, Bithynia tentaculata, Anadoludamnicola gloeri), four species of Pulmonata (Galba truncatula, Radix labiata, Physella acuta, Acroloxus lacustris), and two species of Bivalvia (Pisidium casertanum, Pisidium lilljeborgii). Canonical Correspondence Analysis (CCA) was applied to determine the relationships among the Mollusca fauna and physicochemical variables. CCA explained 31.897% of the species and environmental variation by the second axis. Water temperature (T), dissolved oxygen (DO), pH, and Ca +2were the most influential variables on the Mollusca fauna. The present study is the first research on the Mollusca fauna in the streams of Tunceli province. Molluscs species were recorded for the first time from the area.

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

“…In the present study, all the determined species of Gastropoda are commonly live clean water; they cannot survive in heavily polluted waters. Koşal Şahin and Zeybek (2016) reported that Acroloxus lacustris was showed positive correlation with DO values in Tunceli streams. Theodoxus species commonly lives in running waters of turbulent waters includes taxa living in springs, rivers, lakes and even in low-salinity waters and sometimes on the vegetation (Roth, 1987;Yıldırım, 2004;Yıldırım et al, 2006).…”

Kavak Çayı (Gelibolu, Çanakkale ) Mollusca Faunası ve Bazı Su Kalitesi Özelliklerinin Belirlenmesi

“…Biyolojik izleme programlarında en çok kullanılan ve SÇD kapsamında bir kalite unsuru olan taban büyük omurgasızları su kütlesi hakkında kapsamlı bir değerlendirme imkânı sunmaktadır (Karr, 1999;Kenney, Sutton-Grier, Smith, ve Gresens, 2009;Kazancı vd., 2010). Taban omurgasızları içinde önemli bir yeri olan tatlısu molluskları hakkında ülkemizde yapılan ilk çalışmalar Roth (1839) ile başlamış, müteakiben yerli ve yabancı çok sayıda bilimsel çalışmayla (Schütt, 1964;Schütt ve Bilgin, 1970;Bilgin, 1980;Schütt ve Şeşen, 1993;Yıldırım, 1999;Ustaoğlu, Balık ve Özbek, 2001Öktener, 2004;Yıldırım vd., 2006;Kebapçı ve Yıldırım, 2010;Kılıçaslan ve Özbek, 2010;Koşal-Şahin, Bahadır-Koca ve Yıldırım, 2012;Odabaşı ve Georgiev, 2014;Yıldırım, Kebapçı, Koca ve Yüce, 2015;Koşal-Şahin ve Zeybek, 2016;Gürlek, 2017;Gürlek, Koşal-Şahin, Dökümcü ve Yıldırım, 2019;Gözler ve Baytaşoğlu, 2020;Tomilova vd., 2020;Odabaşı, Akay ve Koyuncuoğlu, 2020;Sands vd., 2020) hız kazanmıştır.…”

The Levels of Bio-Indicator Bacteria in the Fresh Water Resources of Eastern Anatolia Region of Turkey

“…There are a few biological studies related to fish, trichoptera and mollusca fauna of the streams of this region such as: "the meat yield and chemical composition of Salmo trutta macrostigma caught in Munzur River" [9], the distribution of larval trichopteran assemblages [10] and mollusca fauna of the streams of Tunceli [11].…”
