Diagram of experimental configuration.

A: Ambient air at 400 ppm CO2 was bubbled into four 2-L phytoplankton culture bottles for the control pCO2 treatment, and ambient air mixed with pure CO2 to a final concentration of 1,000 ppm CO2 was bubbled into another four 2-L phytoplankton culture bottles for the high-pCO2 treatment; medium was delivered to each bottle from pre-bubbled 20-L media reservoirs. B: Each semi-continuous culture bottle had ports for medium inflow, gas inflow, and media/gas outflow.</p

Copepod reproductive success.

Copepod egg production rate (eggs female-1d-1) (A), percent hatching success (B), and naupliar survival (C) in Experiment I and II after being fed control (400 ppm) and high (1,000 ppm) pCO2 diets. Bar heights represent median values female-1 for all reproductive parameters. Error bars represent interquartile ranges.</p

Phytoplankton fatty acid concentration.

Percent essential fatty acid (EFA), other polyunsaturated fatty acid (PUFA), monounsaturated fatty acid (MUFA), and saturated fatty acid (SFA) comprising total fatty acid per cell under control (400 ppm) and high (1,000 ppm) pCO2 in Experiment I (A) and Experiment II (B).</p
