Zooplankton Dominance Shift in Response to Climate-Driven Salinity Change : A Mesocosm Study
Climate change predictions indicate global changes in salinity with negative implications for plankton food webs; an important baseline for functioning of marine ecosystems. Current understanding of how salinity change will impact plankton communities is mostly limited to the salinization of freshwa...

In this study, we investigate the effect of salinity change on zooplankton communities under different salinity change scenarios of the Baltic Sea.
