The Erfelek Stream and Ecological Importance

Abstract

Although the Erfelek Stream is a small stream with a total length of 80 km and a flood discharge of 302.1 m 3 /sec, from its source to the place where it merges with the sea. It is ecologically very important for its immediate environment in terms of the zonations created by it and the groups of living organisms it contains. The fact that it is the only stream that reaches the sea by forming a delta between the Kızılırmak and Filyos Stream and that it reaches the sea by drawing meanders in the delta after different geological formations it passes through starting from an altitude of 1370 meters allows it to be a stream rich in biodiversity. Karagöl, which is connected with the sea, which is almost destroyed within the delta, and the Aksaz wetlands, which are still continuing their existence increase the importance of the stream in terms of both aquatic products and other groups of living organisms. In the fauna and flora of the Erfelek stream, the presence e few benthic invertebrate, fish, birds, mammals and plant species have been identified up to now. On this study, the importance of biodiversity and ecology of Erfelek Stream is aimed to be revealed as a result of present data and preliminary observations.

Diversity of benthic macroinvertebrates and water quality of Karasu Stream (Black Sea)

“…Various studies have been conducted on the assessment of benthic macroinvertebrates in Sinop province (Akbulut,1996;Bat et al 2000;Akbulut, 2001;Akbulut et al 2001;2002;Ertorun and Tanatmış, 2004;Öktener, 2004;Tanatmış, 2004;Şendoğan, 2006;Tanatmış and Ertorun, 2008;Yardım et al 2008;Aydemir-Çil, 2014;Yardım et al 2017). There is no study carried out on the diversity of benthic macroinvertebrate of the Karasu Stream.…”
