| Popis: | 10 pages, 4 figures, 4 tables Penilia avirostris is an important component of the mesozooplankton of shelf waters during the stratification period. This study investigates the feeding ecology of P. avirostris under natural dietary conditions in the NW Mediterranean during their summer appearance. The results indicate that P. avirostris feeds on particles in a wide size range, mostly on nanoplankton (2 to 20 μm), including larger prey such as dinoflagellates and ciliates. Autotrophic and heterotrophic bacteria were not grazed on, but picoflagellates ( This work was supported by a PhD fellowship from the Spanish Government to D.A., by the Spanish CICYT Projects REN2001-1693 and CTM2004-02575/MAR, and by the Ramón y Cajal Program of the Ministry of Education and Science of Spain |
