Community approaches investigating ocean acidification (OA) effects suggest a high tolerance of micro- and mesozooplankton to carbonate chemistry changes expected to occur within this century. Plankton communities in the coastal areas of the Baltic Sea frequently experience pH variations partly exceeding projections for the near future both on a diurnal and seasonal basis. We conducted a large-scale mesocosm CO2 enrichment experiment (m3) enclosing the natural plankton community in Tvärminne/ Storfjärden for eight weeks during June--August 2012 and studied community and species/ taxon response of ciliates and mesozooplankton to CO2 elevations expected for this century. Besides the response to fCO2, we also considered temperature and chlorophyll a variations in our analyses. Shannon diversity of ciliates significantly decreased with fCO2 and temperature with a greater dominance of smaller species. The mixotrophic Myrionecta rubra seemed to indirectly and directly benefit from higher CO2 concentrations in the ... : Supplement to: Lischka, Silke; Bach, Lennart Thomas; Schulz, Kai Georg; Riebesell, Ulf (2017): Ciliate and mesozooplankton community response to increasing CO2 levels in the Baltic Sea: insights from a large-scale mesocosm experiment.
