Short summary
The present study describes responses of picocyanobacteria (PCY) physiology to different environmental conditions. The cultures were grown under 64 combinations of temperature, irradiance in a photosynthetically active spectrum (PAR), and salinity. The results show that each strain of Baltic Synechococcus sp. behaves differently in respective environmental scenarios. The study develops the knowledge on bloom-forming PCY and reasons further research on the smallest size fraction of phytoplankton.
