AbstractKnowledge of copepod in situ diet is critical for accurate assessment of trophic linkages and transfer efficiencies of the marine food web but is limited due to technical challenges. Here we report, using a recently developed eukaryote-universal copepod-excluding ectobiotic ciliate-blocking protocol, to investigate the natural diets of the copepods Temora turbinata, Subeucalanus subcrassus and Canthocalanus pauper in coastal waters in Sanya Bay, China. Analysis of the resultant 18S rDNA clone libraries revealed diverse diet composition for all the three copepod species, with 11 prey species for C. pauper, 9 for T. turbinata and 9 for S. subcrassus. The ingested materials included land plants, green algae, Metazoa, Euglenozoa and Rhizaria, although species numbers from each of these lineages differed. Broussonetia sp. (land plant), which might have been ingested in the form of pollen or fresh detritus were common among all three copepods, and accounted for a significant proportion (>55%) of the clones sequenced. These results suggest that copepods in Sanya coastal waters might use terrigenous detritus as supplementary food sources when phytoplankton production is limited. However, the significance of the plant detritus as a nutrition source of these copepods remains to be determined by analyzing carbon-based proportion and digestion/assimilation rate of the ingested plant materials.
