The epipelic algae of Çatal Lake were studied between June and October 2002. Fifty-three taxa (39 belonging to Bacillariophyta, 8 to Chlorophyta, 5 to Cyanophyta and 1 to Euglenophyta) were determined. Based on the epipelic algal composition, Çatal Lake can be characterized as eutrophic. | Turk J Biol 28 (2004) 103-109 © TÜB‹TAK Species Composition and Diversity of Epipelic Algae in Çatal Lake (fiebinkarahisar-Giresun, Turkey) Bülent fiAH‹N Department of Biology, Fatih Educational Faculty, Karadeniz Thecnical University, 61335 Sö¤ütlü, Trabzon - TURKEY Received: Abstract: The epipelic algae of Çatal Lake were studied between June and October 2002.

It is situated 1050 m above sea level. The lake has an area of km2 and a depth of about 5 m (Figure 1). Ankara Giresun TURKEY The present paper reveals quantitative characteristics of the algal community structure and provides insights into the factors controlling the species diversity and species composition of epipelic algae in Çatal Lake and contributes to the algal flora of Turkey. ÇATAL LAKE Materials and Methods In order to examine the epipelic algal flora of Çatal Lake, a station was chosen. The number of sampling stations depended on the size of the lake. Collections were made during the snow-free period from .
