Evaluation of the Trophic Status of Karasu River (Erzincan, Türkiye) by Biodiversity Indices

Öz:
This study focuses on seasonal and temporal variations of the biodiversity and composition of the phytoplankton community in Karasu River. The phytoplankton and water samples were collected bimonthly from a depth of 0.5-8 m during the period from January 2019 to July 2019 from five stations. Four diversity indices (Shannon- Wiener, Simpson, Margalef and Menhinick) were studied. MINITAB 15 Software was used to interpret the relationship between the indices. Average water temperature, dissolved oxygen, pH and electritrical conductivity values were measured as 19.43 °C, 7.9 mg L, 8.3 and 465 mS/cm, respectively. In this study, a total of 123 phytoplankton species were identified. Among these species, 106 species belonging to Bacillariophyta group, 10 species belonging to Chlorophyta group, 6 species belonging to Cyanobacteria group and 1 species belonging to Euglenophyta group were included. Throughout the study, Shannon-Wiener, Simpson Margalef, and Menhinick diversity indices were calculated as 1.83 H ́, 11.53, 5.12 and 0.83 and respectively. As a result of this study, phytoplankton diversity indices and ecological status assessment based on water quality were not found to be compatible. However, introducing reference conditions for different cities can increase the usability of the indices thus we recommend expanded further studies.

Karasu Nehri (Erzincan,Türkiye)’nin Trofik Durumunun Biyoçeşitlilik İndeksleriyle Değerlendirilmesi

Öz:
Bu çalışma, Karasu Nehri'ndeki fitoplankton kompozisyonunun ve biyolojik çeşitliliğinin mevsimsel ve zamansal değişimlerine odaklanmıştır. Fitoplankton ve su örnekleri Ocak 2019-Temmuz 2019 döneminde iki ayda bir 0.5-8 m derinlikten beş istasyondan toplanmıştır. Dört çeşitlilik indeksi (Shannon-Wiener, Simpson, Margalef ve Menhinick) incelenmiştir. Endeksler arasındaki ilişkiyi yorumlamak için MINITAB 15 yazılımı kullanılmıştır. Ortalama su sıcaklığı, çözünmüş oksijen, pH ve iletkenlik değerleri sırasıyla 19.43 °C, 7.9 mg/L, 8.3 ve 465 mS/cm olarak ölçülmüştür. Bu çalışmada toplam 123 fitoplankton türü tespit edilmiştir. Bu türlerden Bacillariophyta grubuna ait 106 tür, Chlorophyta grubuna ait 10 tür, Cyanobacteri grubuna ait 6 tür ve Euglenophyta grubuna ait 1 tür teşhis edilmiştir. Çalışma boyunca Shannon-Wiener, Simpson Margalef ve Menhinick çeşitlilik indeksleri sırasıyla 1.83 H ́, 11.53, 5.12 ve 0.83 olarak hesaplanmıştır. Bu çalışma sonucunda fitoplankton çeşitlilik indeks değerleri ile Karasu Nehri’nin su kalitesine bağlı ekolojik durum değerlendirilmesi bir biri ile uyumlu olmadığı tespit edilmiştir. Ancak farklı şehirler için referans koşulların geliştrilmesi endekslerin kullanılabilirliğini artırabilir. Bu nedenle bu çalışmaların devam etmesini ve yaygınlaşmasını öneriyoruz.
