dc.description.abstract | Experiments to determine egg production and feeding rates of Oithona davisae were carried out under controlled laboratory conditions. From copepodite IV stage on, the animals were fed the heterotrophic dinoflagellate Oxyrrhis marina in a wide range of concentrations (from 10 µg C L−1to 286 µg C L−1), and adult females were daily monitored to study different aspects of their fecundity. Both clutch and egg-production rate increased with food concentration, with values from 8 to 20 eggs for the clutch size, and from 1.8 eggs to 6.3 eggs female−1 d−1 for the egg production. In addition, to assess the efficiency of conversion of food intake into egg mass, two feeding experiments were conducted. Maximum weight-specific ingestion rates (≈ 80% body C d−1) and the egg-production efficiency (16%) were lower than those reported for free-spawning calanoid copepods. The fact that satiating food concentrations for feeding and egg production of adult females of Oithona davisae were rather low suggests an adaptation to exploit oligotrophic environments, and might explain the ecological success of the genus in situations when food becomes limiting for other groups of copepods | es_ES |
dc.description.sponsorship | This work was funded by the Spanish Ministry of Education and Science (current Ministry of Economy and Competitiveness) through a Ph.D. fellowship (BES-2008-004231) to S. Z. and the research project CTM2007-60052 and CTM2011-23480 to E.S. This is a contribution of the Marine Zooplankton Ecology Group (2009SGR-1283) at the Institut de Ciències del Mar. We thank M. Antó and P. Jiménez for taking care of the stock cultures of algae and copepods. We also thank R. Almeda, A. Calbet, and M. Alcaraz for their advice. We finally thank M. R. Landry and two anonymous reviewers for their constructive comments on the manuscript | es_ES |
