Phytoplankton and zooplankton structure of Sultan marshes in central Anatolia

Abstract

In this study, the focus is on the planktonic organisms which were identified during the field studies conducted between August 1993-October 1994. The overall zooplankton density was low during winter. However Copepods started to become abundant in the late summer and fall periods while rotifers were abundant in spring. From the Sultan Marches, a total of 26 Rotifera, 3 Cladocera and 2 Copepoda species have been identified. Among phytoplanktonic organisms, a total of 175 species were identified. The effects of water quality variables which depend on the seasonal distribution and the succession of the zooplankton taxa, as well as the interrelation with phytoplanktonic organisms, were also discussed.
