El objetivo del presente estudio es evaluar la biomasa, diversidad y relación del fitoplancton con las comunidades planctónicas estuarinas basándose en las condiciones ambientales durante la época de verano......The principal objective was to know the distribution of chlorophyll, cell counts and qualitative (net 50µ) on the community of the phytoplankton accomplished in five profiles around of the city of Guayaquil (estuary interior) between 8th and 14th of may/2001. There were identified 87 species in water samples and 110 species in net samples (50µ), in the community of the phytoplankton. The diatomms prevailed dominant and in smaller concentration the dinoflagellates, tintinnoids, silicoflagellates, cianobacters and flagellates. In cell counts Pseudonitzschia longissima y Skeletonema costatum, they were the species of greater concentration in all the area. In net samples (50µ), were registered species stuarines and benthics: Polymixis coranalis, Actinoptychus splendes, Chaetoceros affinis, to report a height variability and abundance of species. The distribution and dominance of species presented a which one characteristic for the area......
