Abstract :

Arda River, being one of the biggest tributaries of Meriç River passes through Bulgaria, Greece and merges to the Meriç River in Edirne provincial borders. Only 500 meter of the river is inside Turkey borders and sampling station selected this area. In this study, the species structure and quantitative development of the summer phytoplankton and epilithic algae were examined in 2011. A total of 57 species was found, belonging to 4 divisions: Bacillariophyta 31 taxa, Chlorophyta 18 taxa, Euglenophyta 5 taxa and Cyanophyta 3 taxa. The most common taxa in the phytoplankton were Pediastrum sp., Cyclotella meneghiniana and Cymatopleura sp. while Cymatopleura sp., Fragilaria sp. and Pinnularia sp. were the most common in the epilithic. Canonical correspondance analyses have been applied to clarify relationships between environmental variables and planktonic and benthic algae. The results of the CCA showed differing relationships between the environmental variables and the phytoplanktonic and epilitic taxa.
