| Summary: | Ocean acidification is caused by increasing amounts of carbon dioxide dissolving in the oceans leading to lower seawater pH. We studied the effects of lowered pH on the calanoid copepod Eurytemora affinis during a mesocosm experiment conducted in a coastal area of the Baltic Sea. We measured copepod reproductive success as a function of pH, chlorophyll a concentration, diatom and dinoflagellate biomass, carbon to nitrogen (C : N) ratio of suspended particulate organic matter, as well as copepod fatty acid composition. The laboratory-based experiment was repeated four times during 4 consecutive weeks, with water and copepods sampled from pelagic mesocosms enriched with different CO2 concentrations. In addition, oxygen radical absorbance capacity (ORAC) of animals from the mesocosms was measured weekly to test whether the copepod's defence against oxidative stress was affected by pH. We found no effect of pH on offspring production. Phytoplankton biomass, as indicated by chlorophyll a concentration and ... : Supplement to: Almén, Anna-Karin; Vehmaa, Anu; Brutemark, Andreas; Bach, Lennart Thomas; Lischka, Silke; Stuhr, Annegret; Furuhagen, Sara; Paul, Allanah Joy; Bermúdez Monsalve, Rafael; Riebesell, Ulf; Engström-Öst, Jonna (2016): Negligible effects of ocean acidification on Eurytemora affinis (Copepoda) offspring production.
