| Popis: | 13 pages, 3 figures, 4 tables Despite the acknowledged importance of small copepods of the genus Oithona in marine pelagic ecosystems, there is little information about their ecological role, potential food resources and egg production rates (EPR) in tropical environments. In the present study, feeding and EPR of adult females of two species of Oithona were determined in two different tropical marine food webs in North Queensland, Australia, during the 2011 austral autumn. Oithona attenuata was studied in the waters of the Great Barrier Reef lagoon, and Oithona dissimilis was studied in a mangrove area. Oithona spp. ingested dinoflagellates and ciliates preferentially to other prey items of the nano- and microplankton assemblage. Oithona spp. clearance rates on dinoflagellates and ciliates ranged from 3.7 to 10.4 mL female−1 day−1, and from 4.3 to 18.1 mL female−1 day−1, respectively. The daily body carbon ingested per female was This work was funded by the Spanish Ministry of Economy and Competitiveness through a Ph.D. fellowship to S.Z.-T.
