Cerenkov radiation was used to measure ingestion and release by Brachionus calyciflorus and Daphnia pulex that were fed 32P-labeled Rhodotorula glutinus. A method is described that uses automatic pipet tips as cages, permitting measurement of ingestion rates and isotope loss by individual animals. Estimated gut renewal times were 16 min for B. calyciflorus and 25–28 min for D. pulex. Filtering and ingestion rates for both animals agree closely with previous estimates. B. calyciflorus release… CONTINUE READING
