摘要: To examine the potentially competing influences of microzooplankton and calcite mineral ballast on organic matter remineralization, we incubated diatoms in darkness rolling tanks with without added minerals (coccoliths) (rotifers). Concentrations particulate (POM suspension or aggregates), dissolved (DOM), inorganic nutrients were monitored over 8 days. The presence rotifers enhanced remineralization ammonium phosphate, but not silicon, from biogenic matter, up to 40% which became incorporated into aggregates early experiment. Added resulted rates excretion phosphate by that depressed 67% 36%, respectively, demonstrating potential for inhibit destruction POM zooplankton water column. Lastly, a more rapid initial rate aggregation, although greater overall amount aggregation during
