ROTIFERA COMMUNITY AS AN INDICATOR OF THE ECOLOGICAL STATUS OF LAKE PRESPA (R.N. MACEDONIA)
View through CrossRef
The ecological status of Prespa Lake was determined on the basis of taxonomic (number of species, diversity, density) and functional properties (feeding strategy) of rotifers. 44 species were found, 35 littoral and 9 pelagic with an average population density of 25 ind. L-1 and a remarkable share (65%) in the zooplankton assemblage. Microphagous Kellicottia longispina and Keratella cochlearis dominate in spring and summer, and raptorial Polyarthra vulgaris and Synchaeta pectinata in autumn. The dominance of microphagous rotifers indicates increased productivity in Lake Prespa. Pearson's correlation shows that the abundance of rotifers is significantly related to TP and TN.Taxonomic and functional characteristics of rotifers can be an useful indicator of ecological processes in freshwater ecosystems.
