Abstract

This study is the first investigation to evaluate the zooplankton community structure of Boraboy Lake, a landslide-dammed freshwater ecosystem located in Amasya Province, Türkiye. Seasonal sampling was conducted in spring, summer, autumn, and winter at four stations. Physicochemical parameters, such as temperature, pH, dissolved oxygen, electrical conductivity (EC), Secchi depth (SD), total phosphorus (TP), total nitrogen (TN), and chlorophyll a (Chl-a), were measured and evaluated using Carlson’s Trophic State Index (TSI), OECD classification, and Turkish Surface Water Quality Regulation. Results showed that Boraboy Lake generally exhibits oligotrophic to mesotrophic characteristics, with an average TSI value of 31.6. A total of 36 zooplankton species were identified: 26 Rotifera, eight Cladocera, and two Copepoda. Dominant taxa included Eudiaptomus gracilis , Keratella cochlearis , and Bosmina longirostris , while Polyarthra vulgaris and Asplanchna priodonta showed seasonal peaks. These findings highlight the ecological significance of Boraboy Lake and underscore the importance of regular monitoring to ensure the long-term sustainability of its biodiversity and ecosystem services.

Özet

Bu çalışma Amasya ilinde yer alan heyelan set gölü olan Boraboy Gölü’nün, zooplankton komünite yapısının değerlendirildiği ilk çalışmadır. İlkbahar, yaz, sonbahar ve kış olmak üzere mevsimsel örneklemeler toplamda dört istasyonda gerçekleştirilmiştir. Sıcaklık, pH, çözünmüş oksijen, elektriksel iletkenlik (EC), Secchi diski derinliği (SD), toplam fosfor (TP), toplam azot (TN) ve klorofil-a (Chl-a) gibi fiziko-kimyasal parametreler ölçülmüş; Carlson Trofik Seviye İndeksi (TSI), OECD sınıflandırması ve Türkiye Yüzeysel Su Kalitesi Yönetmeliği çerçevesinde değerlendirilmiştir. Sonuçlar, gölün genel olarak oligotrofik ile mezotrofik özellikler gösterdiğini ve ortalama TSI değerinin 31,6 olduğunu ortaya koymuştur. Zooplankton topluluk yapısı incelendiğinde toplam 36 tür belirlenmiştir: 26 Rotifera, 8 Cladocera ve 2 Copepoda. Baskın taksonlar arasında Eudiaptomus gracilis , Keratella cochlearis ve Bosmina longirostris yer alırken, Polyarthra vulgaris ve Asplanchna priodonta mevsimsel pikler göstermiştir. Bulgular, Boraboy Gölü’nün ekolojik önemini vurgulamakta ve biyolojik çeşitliliğin sürdürülebilirliği için düzenli izleme gerekliliğini ortaya koymaktadır.
