Abstract

The phytoplankton assemblages were investigated in Lake Crniševo that belongs to group of Baćinska Lakes. Samples were collected monthly from April to September 2010 at the 1, 5, 10, 15, 20 and 25 meters depth and analysed with Utermöhl method. The main aims of the investigation were to 1) determine taxonomic composition of phytoplankton assemblage, its abundance and biomass in a karstic lake and furthermore; 2) apply functional and morphologicaly based approach; 3) determine which description of the community is the most appropriate in understanding phytoplankton sucession. In the Lake Crniševo dominant species was Ceratium hirudinella while Dinobryon divergens, Ankistrodesmus sp. and Oocystis sp. were codominant. Dominant functional group was LO with groups E, J and B as codominant functional groups. Dominant morphologicaly based group was IV and codominant VI. Phytoplankton biomass varied from 0, 08 mg l-1 (May, June) to 2, 86 mg l-1 (August) when maximum biomass has been reached (Peridiniopsis borgei). In conclusion, morphologicaly based functional groups describe phytoplankton assemblage sucessfully and together with functional approach make understanding of fitoplankton sucession easier. Morphologicaly based groups have an advantage in relation to taxonomic and functional clasification due to easy and objective approach.
