Phytoplankton (except Bacillariophyceae) Flora of Lake Golkoy (Bolu)

摘要

The phytoplankton composition of Lake Golkoy was studied by monthly sample collection from 3 littoral and 2 pelagic stations during a 2-year period (June 2003-June 2005). in total, 152 taxa belonging to Chlorophyta (61.8%), Euglenophyta (12.5%), Cyanoprokaryota (10.5%), Pyrrophyta (5.3%), Chrysophyta (4.6%), Cryptophyta (3.9%), Xanthophyta (0.7%), and Prasinophyta (0.7%) were identified. Spirogyra and Scenedesmus were the most abundant genera, with 13 and 10 species, respectively. Some species foundin the lake were new records for the Bolu region (e.g., Gonium perforate Muller, Polytoma cylindraceum Pasher 1927, Provasoliella ovata (Jacobsen) Loeblich, and Anabaena crassa (Lemmermann) Komarkova-Legnerova & Cronberg).
