Abstract

Özet. Küçük Lota Gölü fitoplankton toplulukları ve göl suyunun fiziko-kimyasal özellikleri Kasım 2000-Aralık 2001 tarihleri arasında incelenmiştir. Fitoplanktonda 7 bölüme ait toplam 119 takson belirlenmiştir. Bu taksonların 41 tanesi Bacillariophyta (% 34,6), 38 tanesi Chlorophyta (% 32,7), 23 tanesi Cyanophyta (% 19,3), 7 tanesi Pyrrophyta (% 5,9), 4 tanesi Cryptophyta (% 3,4), 4 tanesi Euglenophyta (% 3,4) ve 2 tanesi Xanthophyta (% 1,7) bölümlerine aittir. Küçük lota gölünde yıllık ortalama sıcaklık: 16,9 oC, çözünmüş oksijen: 6,8 mg/l, pH: 8,4, toplam fosfat: 56,2 μg/l, nitrat: 0,2 mg/l, amonyak: 149,8 μg /l, silika: 2,6 mg/l, kalsiyum: 417,7 mg/l, sülfat: 302,3 mg/l ve klorofil a:1,3 μg/l’dir. Küçük Lota Gölü biyolojik ve kimyasal özellikleri bakımından oligotrofik karakter göstermektedir.

 

Abstract. Phytoplankton communities of Small Lota Lake and physical-chemical properties of the lake water were examined between November 2000 and December 2001. 119 taxa belong to seven divisions in Phytoplankton. Of these taxa belong to 41 Bacillariophyta (34.6 %), 38 Chlorophyta (32.7 %), 23 Cyanophyta (19.3 %), 7 Pyrrophyta (5.9 %), 4 Cryptophyta (3.4 %), 4 Euglenophyta (3.4 %) and 2 Xanthophyta (1.7 %). The annual means of temperature, dissolved oxygen, pH, total phosphate, nitrate, amonia, silica, calcium, sulphate and chlorophyll are 16.9 oC , 6.8 mg/l, 8.4, 56.2 μg/l, 0.2 mg/l, 149.8 μg /l, 2.6 mg/l, 417.7 mg/l, 302.3 mg/l and 1.3 μg/l respectively. Small Lota Lake exhibits oligotrophic character in terms of the biological and chemical properties.
