| Ultraphytoplankton is composed by a group of organisms phylogenetically diverse, which contribute significantly to the total biomass and primary production in different oceanic and coastal pelagic systems. The success of ultraphytoplankton is attributed to its high efficiency in capturing light and nutrients, due to their small cell size and low sinking rate. The community structure is driven by the interaction among biotic and abiotic variables, such as temperature, nutrients, light and predators. The objective of this work was to assess the ecological importance of ultraphytoplankton organisms at the EPEA station, situated in the Buenos Aires coastal pelagic system (Argentina, SW Atlantic), during the period 2000-2009. In particular, ultraphytoplankton... |
