摘要: The structure of the psammic rotifer community in three ecotonal zones (arenal, interface, eulittoral) a mesotrophic lake (Lake Piaseczno; Leczna — Wlodawa Lakeland, eastern Poland) was studied June and September 1996 1997. A total number 48 taxa, belonging to different groups psammon (eupsammon, hygropsammon hydropsammon), were identified: 6 psammobionts, 16 psammophiles 26 psammoxens. In each zone, rotifers clearly differentiated both qualitatively quantitatively, depending upon season chemical factors. For instance, species diversity indicates positive correlation with parameters: pH, oxidation demand PO 4 3− concentration.
