Descrição
Resumo:Diet of the ascidian Ecteinascidia turbinata (Ascidiacea: Perophoridae) in two mangrove areas ofCuba. Stomach contents of 88 zooids of Ecteinascidia turbinata Herdman 1880 and the qualitative and quantitativecomposition of phytoplankton in the water column were studied in Santa Fe (North Coast of Havana) andPunta del Este (SW of Cuba). We identified 59 microalgal species and four tintinnids in the stomachs. Cell sizewas 75-165 µm in length and 2-105 µm in width. There were not significant differences in microalgal diversityin the water column in the two locations. In both locations, the diatoms had the largest number of species andindividuals in stomachs and water. In Santa Fe, dinoflagellate biomass was larger in water and stomach contents,while in Punta del Este the contribution of each group to the stomach content was similar to that of the watercolumn. This species filters in a constant and irregular way during the day, independently of food availability.Rev. Biol. Trop. 55 (2): 499-507. Epub 2007 June, 29.
