| 英文摘要 | We investigated the community structure, diversity and trophic role of ciliates in the sediments from 48 stations in the Yellow Sea using Ludox density centrifugation and quantitative protargol stain. The ciliate abundance ranged from 1 to 221 cells cm(-3) and biomass from 0.0001 to 0.47 mu g C cm(-3) in the upper 8 cm of the sediments. On average, 77% of ciliate abundance and 81% of biomass were distributed in the 0-2 cm sediment layers, while the respective proportions were only about 6% and 3% in the 5-8-cm layers. Among the 198 morphospecies, Prostomatea was the most dominant group accounting for 45% of the total abundance and 58% of the total biomass. Carnivorous ciliates constituted the primary feeding type, occupying about 64% of the total biomass, followed by bacterivores (21%), algivores (12%) and omnivores (3%). The ciliate abundance and biomass in the upper 5 cm of sediments were two orders of magnitude higher than those in the upper 10 m of the Yellow Sea water column. The estimated ciliate bacterivory and herbivory indicate that ciliate ingestion had little direct influence on bacterial standing stock but possibly had an important impact on diatoms in the sediments from the Yellow Sea.
