*Cellular carbon content for Rhodomonas sp. and Alexandrium fundyense were computed applying volume to carbon conversions¹⁰.

**A. fundyense toxicity in stock cultures was measured daily during the duration of the experiment, and toxin ingestion was calculated from grazing rate experiments¹⁰, which were conducted in parallel to the incubations for the RNA-Seq experiment.
