A three samplings were carried out between September 2014 and August 2015, at twelve stations to determine the seasonal changes of species, relations with water quality parameters, and the Malacostraca fauna of the Upper Coruh River Basin. A hand net was used to collect the biological samples. Dissolved oxygen, temperature, pH, electrical conductivity, and total dissolved solids were measured using a portable water meter. Nitrite, ammonium, phosphate, and biochemical oxygen levels were also measured. Seven taxa were identified (five of them belong to Amphipoda, one to Isopoda, and one to Decapoda). Gammarus birsteini was the continuous, while G. kischineffensis and Asellus aquaticus are common. G. fossarum, G. balcanicus, Gammarus sp. and Potamon ibericum were rarely found. AF (Aydıncık Foundation) and DF (Değirmencik Foundation) stations had first class water quality while other stations had second and third quality according to the Quality Criteria According to Classes of Inland Water Resources.
During fieldwork on the southeastern Black Sea coast, in October 2009, two gnathiid isopods were found in their free-living stage, Paragnathia formica (Hesse, 1864) and Gnathia maxillaris (Montagu, 1804). These species are herein reported from the Black Sea for the first time.
In this study, Mollusca (Gastropoda, Bivalvia) samples obtained from different distributaries drains the Çoruh River Basin were examined. It was aimed to contribute to the knowledge of mollusc species distribute in inland waters of Turkey. The samples were taken from 21 different locations at different times. At the end of the study, a total of 9 species of Dreissena
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
