Ephemeroptera (Insecta) fauna in freshwater ecosystems of the Black Sea Region of Türkiye

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.
