In this study, we aimed to determine the reference sites and their reference Ephemeroptera communities according to the Water Framework Directive methods in the Eastern Part of the Black Sea Region of Turkey between 2008-2011. From the area, twentyfour collecting sites were chosen. There were thirty Ephemeroptera species identified, belonging to seven families and eleven genres. Cluster analysis based on Bray-Curtis similarities was applied. Reference habitat conditions of the studied sites and their reference Ephemeroptera communities were determined by combining both ecological and statistical results. As a result, sixteen sites had reference habitat conditions and their reference Ephemeroptera species were identified.

This research aims to investigate the Simuliidae fauna of Yeşilırmak River basin and determine the species composition of the collecting sites. The study was carried out in July 2008 and June 2009. One genus and eleven species (Metacnephia sp., Metacnephia subalpina, Simulium (Eusimulium) angustipes, Simulium (Nevermannia) costatum, Simulium (Simulium) argenteostriatum, Simulium (Simulium) bezzii, Simulium (Simulium) ornatum, Simulium (Simulium) trifasciatum, Simulium (Simulium) variegatum, Simulium (Wilhelmia) balcanicum, Simulium (Wilhelmia) lineatum and Simulium (Wilhelmia) pseudequinum) were recorded from 16 collecting sites. The distribution and abundance of Simuliidae species reflect the changes in water quality of Yeşilırmak River, due to agricultural activities and urban areas.
