Seasonal dynamics of the zooplankton community in the Ikizcetepeler Reservoir (Balıkesir, Turkey) related to certain physicochemical parameters

Abstract

Seasonal dynamics in the zooplankton community and its relations with certain physicochemical parameters (water temperature, Secchidisk transparency, conductivity, total nitrogen (TN), total phosphorus (TP), pH and chlorophyll-a) were studied in the eutrophic Ikizcetepeler Reservoir from February 2007 to March 2008. Daphnia longispina, Bosmina longirostris, Ceriodaphnia pulcella and Cyclops vicinus was dominant throughout the year; Acanthocyclops robustus was dominant in fall and summer and Asplanchna priodonta was dominant in fall and spring at all stations. Canonical correspondence analysis (CCA) showed that Cyclops vicinus had high correlations to water temperature, Bosmina longirostris and Daphnia longispina were correlated to pH the dominant species were cosmopolitan and characteristic to the eutrophic temperate lake zooplankton community members.
