Annual cycle of microphytoplankton from the coasts of the tropical Mexican Pacific

Abstract:

Despite the length of littorals, studies of annual cycles for phytoplankton in the Mexican Pacific are rare, especially in tropical areas. A study of the phytoplankton (basically microphytoplankton) was realized in six locations off the States of Jalisco and Colima, from June, 2001 to May, 2002. A total of 286 taxa belonging to the taxonomic groups diatoms, dinoflagellates, cyanophyceae and silicoflagellates were identified. The best represented groups were dinoflagellates (157 taxa) and diatoms (119 taxa). Moreover, the study included a small fraction (15-25%) of the diatom planktonic flora and 43% of the dinoflagellate flora from the Mexican Pacific. The flora showed a strong tropical-subtropical affinity. Dinoflagellate species appeared to be more important in late spring and early summer, whereas relative abundance of diatoms was higher most of the year of study. Five new records of dinoflagellates for the Mexican …
