DOI : 10.4194/1303-2712-v19_6_06 Viewed : 2882 - Downloaded : 2579 Seasonal dynamics in the zooplankton community and its relationships with certain physicochemical parameters (water temperature, Secchi disk transparency, conductivity, nitrate-nitrogen (NO3-N), phosphate (PO4), pH, oxidation-reduction potential (ORP) and chlorophyll-a) were studied in the eutrophic Çaygören Reservoir, Turkey from February 2007 to March 2008. Cyclops vicinus was dominant throughout the year; Acanthocyclops robustus was dominant in fall and summer; Asplanchna priodonta was dominant in fall, winter and spring at all stations. Canonical correspondence analysis (CCA) showed that A. robustus had high correlations to conductivity, C. vicinus to PO4 and NO3-N and Metacyclops gracilis to water temperature and chl-a. The number of individual were significantly different among the seasons and stations (P<0.05). The number of species were significantly different among the seasons (P<0.05), but not among the stations (P>0.05). Zooplankton community in the Çaygören Reservoir underwent changes in species composition from small-bodied Keywords : Canonical correspondence analysis, Cladocera, Copepoda, Rotifera
