Comparison of F1- and F2-generation response of red abalone to high CO2. (A) Under high CO2, Santa Barbara family SB-E-F1 exhibited a 67% decline in survival. (B) This trend repeated in experiments on SB-E-F2 descendants after a generation in a common garden environment, with an aggregate 68% decline in survival under high CO2 in the subsequent generation. When subdivided into paternal family responses, a significant paternal family × CO2 interaction was observed in the F2 generation (P < 0.0001). Shared letters indicate group means that are not significantly different based on means comparisons of least squares group estimates (P > 0.05).
