| Abstract: | In July and August, 1974, standing crops of Ceriodaphnia spp. and Diaphanosoma brachyurum were greater in the area of the littoral zone of Par Pond (Savannah River Plant, Aiken, South Carolina, U.S.A.) receiving hyperthermal effluent from a nuclear reactor than in an ambient area, while Bosmina longirostris maintained higher standing crops in the ambient area than in the area receiving hyperthermal effluent. In August, 1974, exclosures were placed in the effluent-affected area to test the hypothesis that the high density of rooted aquatic macrophytes in the effluent-affected area influences the standing crop of thexe Cladocera. The effects of changes in reactor effluent temperature in addition to the presence of vegetation were observed in the exclosure experiments. The results of the exclosure study support two generalizations: the presence of dense rooted vegetation allows higher standing crops of Ceriodaphnia spp. and D. brachyurum; and lower temperatures than those usually found at the heated station would favor B. longirostris standing crops, while the higher effluent temperatures favor Ceriodaphnia supp. and D. brachyurum. |
