We measured the vertical and seasonal distribution of picoplankton (0.2-2 microm) and nanoplankton (2-20 microm) in the photic layer of Cuban southern oceanic and coastal waters. The concentration of the different fractions was estimated by epifluorescence microscopy. Heterotrophic components from the different fractions showed higher vertical stratification in the oceanic station in comparison...

I am interested in understanding how, and in what ways, the taxonomic composition of the phytoplankton affects ecosystem-level processes in the sea. I am particularly interested in the relationship between the optical environment and the distribution of phytoplankton with different light harvesting pigments. To this end, I have been working in collaboration with experts in remote sensing and oc...
