Epipelic and epilithic algae of the Yedigöller lakes (Erzurum Turkey)

The epipelic and epilithic algae of the Yedigöller Lakes were studied qualitatively between June and September 2001. As a result 90 taxa (43 belonging to Bacillariophyta, 33 to Chlorophyta, 11 to Cyanophyta and three to Euglenophyta) were determined. | Turk J Biol 26 (2002) 221-228 © TÜB‹TAK Epipelic and Epilithic Algae of the Yedigöller Lakes (Erzurum-Turkey) Bülent fiAH‹N Department of Biology Education, Fatih Education Faculty, Karadeniz Technical University, 61335, Sö¤ütlü, Trabzon - TURKEY Received: 01.04.2002 Abstract: The epipelic and epilithic algae of the Yedigöller Lakes were studied qualitatively between June and September 2001. As a result 90 taxa (43 belonging to Bacillariophyta, 33 to Chlorophyta, 11 to Cyanophyta and three to Euglenophyta) were determined. Based on the algal community composition, the Yedigöller Lakes can be characterized as oligotrophic. Key Words: Epipelic, Epilithic, Algae, Yedigöller Lakes.

Introduction BLACK Given the continual increase in pressure on aquatic biota caused by pollution, it is increasingly urgent to study intact, natural ecosystems prior to their disturbance (1). The Yedigöller Lakes are ideal examples of a natural system unaffected by anthropogenic pollution. These lakes are largely ecologically intact and remote from industrial and agricultural centers. SEA Ankara Erzurum T U R K E Y The Yedigöller Lakes consist of seven small or large lakes between 1 and 5 km2, on Mount K›z›lkaya in Erzurum. The Yedigöller Lakes are glacier lakes, between 3100 m and 3142 m above sea level and located at latitude 40 52’ 32’’ N, longitude 40 37’ 30’’ E (Figure 1). YED‹GÖLLER The purpose of this study was to determine the composition of epipelic and epilithic algae of the Yedigöller .
