Abstract :The algae of Değirmendere River were investigated in the samples collected from different habitats insert ignore into journalissuearticles values(epipelic, epilithic); in five stations between October 1998 and September 1999. The flora consisted of 74 taxa belonging to Bacillariophyta insert ignore into journalissuearticles values(52);, Chlorophyta insert ignore into journalissuearticles values(10);, Cyanophyta insert ignore into journalissuearticles values(9); and Euglenophyta insert ignore into journalissuearticles values(3);. Bacillariophyta was dominant in the algal flora. Aulacosira varians Ag. insert ignore into journalissuearticles values(Coscinodiscaceae);, Amphora ovalis Kütz. insert ignore into journalissuearticles values(Cymbellaceae);, Cocconeis placentula var. euglypta insert ignore into journalissuearticles values(Ehr.); Cleve insert ignore into journalissuearticles values(Achnanthaceae);, Ceratoneis arcus Kütz. insert ignore into journalissuearticles values(Fragilariaceae);, Cymbella minuta Hilse ex Rabh. insert ignore into journalissuearticles values(Cymbellaceae);, Didymosphenia geminata insert ignore into journalissuearticles values(Lyngb.); M. Schmidt. insert ignore into journalissuearticles values(Gomphonemaceae);, Navicula odiosa Wallace insert ignore into journalissuearticles values(Naviculaceae);, Surirella ovata Kütz. insert ignore into journalissuearticles values(Surirellaceae); and Synedra ulna insert ignore into journalissuearticles values(Nitzsch); Ehr. insert ignore into journalissuearticles values(Fragilariaceae); were the most common taxa in the algal flora. While the maximum density of the epipelic community was found to be 12083 cells/cm2 in August, the minumum density was 3855 cells/cm2 in December. The speed of the water current has a great impact on the development of the algal flora.
