Abstract
1. The size of the labeled free glycine pools in recently fed Aurelia aurita polyps exposed to dissolved C14 glycine increased with salinity from 10 to 30‰; the decline at 40% is probably a reflection of stress on the animals. 2. The percentage of radioactivity present as ethanol insoluble material was inversely related to salinity between 10 and 30‰. 3. The rate of glycine uptake was unaltered after 288 hours of food deprivation at 10, 20, 30 and 40%. 4. The oxidation of radioactive glycine taken up from solution, as measured by the collection of C14O2, increased two-to threefold in starved polyps at 10, 20 and 30‰. 5. It is suggested that experiments utilizing starved animals, in which substrates derived from solid food are low, are of importance in elucidating the role of dissolved organic compounds as supplemental energy sources for marine invertebrates.
