Phytoplankton traits distribution along salinity gradients

Global warming causes changes in oceanic salinity with fresh regions, such as Baltic Sea, becoming fresher and salty regions becoming saltier.

Sensitivity to salinity change differs among species causing shifts in community composition, which in turn affect functioning of ecosystems and oceanic biogeochemistry. We investigate how salinity affects the resource utilization traits that determine competitive ability of different phytoplankton groups and how this transfers into stoichiometric patterns observed in the Baltic Sea.
