| Summary: | Mean (+ SE) in situ feeding rates (a), in situ intraspecific aggression (b), and total stomach content weights (c–e) of male and female/juvenile crested blenny, blue-eyed, and Yaldwin’s triplefins, respectively, at controls and CO 2 vents. The total stomach content weight is standardised as a function of fish size. Foraging and aggression data are from year 2017, while food intake data are from 2018 and 2019; no in situ foraging and aggression data could be obtained for the crested blenny in 2017. No significant CO 2 effects were observed for the graphs above, except for a lower stomach content weight at vents for the blue-eyed triplefin (* p < 0.05; see S2 Table ). See S1 Data for the underlying data. (PDF)
