Macrophyte influence on the structure and productivity of photosynthetic picoplankton in wetlands

We used multiple approaches to analyze photosynthetic picoplankton (PPP) structure and production in a wetland in the Lower Paraná Basin (Argentina). A seasonal field survey was combined with an experimental study to analyze PPP variability under different light conditions. Flow cytometry analyses showed differences in PPP structure among the aquatic environments. Three main picoplankton populations were distinguished: phycocyanin-rich...
