Wich factors control the picoplankton community structure in the ocean?
Comunicación oral Picoplankton are the most abundant organisms in the ocean, often dominate planktonic biomass and primary production, and they could represent a substantial contribution to the global export of carbon. Nowadays, we have a limited understanding about the factors that control the pico...
