Ocean acidification effects on the nutritional quality of phytoplankton for copepod reproduction
Four species of phytoplankton (Rhodomonas salina, Skeletonema marinoi, Prorocentrum micans, Isochrysis galbana) were grown under present-day low (400ppm pCOi, pH~8.1) and predicted-future high (lOOOppm pCOi, pH~7.8) ocean acidification conditions using nitrate-limited semi-continuous batch cultures....
