Abstract

Purpose: This study presents the Ephemeroptera fauna in various freshwater habitats in the Black Sea region of Türkiye. Method: A total of 35 sampling stations in the Black Sea region were surveyed between 2016 and 2019. Findings: 3077 samples from 34 taxa were identified in the Black Sea, representing 8 families and 15 genera overall. Caenis macrura was the most dominant species in the region. Diversity indices and dominance values suggest that most stations in the region reflect β- and α-mesosaprobic conditions, indicating moderate organic pollution. Conclusion: The study recorded 7 new provincial records for Ephemeroptera in Türkiye, significantly contributing to the national mayfly fauna. These findings underscore the need for continued faunal surveys and conservation efforts in Turkish freshwater ecosystems.

Özet

Amaç: Bu çalışmada, Türkiye'nin Karadeniz bölgesindeki çeşitli tatlı su habitatlarındaki Ephemeroptera faunasının bir analizi sunulmaktadır. Metod: 2016-2019 yılları arasında 35 örnekleme istasyonu araştırılmıştır. Bulgular: Karadeniz Bölgesi'nde 3077 bireyden 34 takson tespit edilmiş olup, toplamda 8 familya ve 15 cinse ait örnek teşhis edilmiştir. Caenis macrura, bölgede dominant tür olarak tespit edilmiştir. Çeşitlilik indeksleri ve baskınlık değerleri, bölgede çoğu istasyonun orta düzeyde organik kirliliğe işaret eden β ve α-mesosaprobik koşulları yansıttığını göstermektedir. Sonuç: Çalışma sonucunda Türkiye'de Ephemeroptera faunası için 7 yeni il kaydı kaydedilmiş ve Türkiye için Ephemeroptera faunasına önemli katkılarda bulunulmuştur. Bu bulgular, Türkiye tatlı su ekosistemlerinde fauna araştırmalarının ve koruma çalışmalarının sürdürülmesi gerekliliğini vurgulamaktadır.
