| Summary: | Mean (+ SE) benthic food abundance (a), in situ feeding rates (b), total stomach content weights (c), and in situ intraspecific aggression rates (d) of mature male and female/juvenile common triplefin at controls and CO 2 vents in 2017. Intraspecific aggression refers to aggressive behaviours of females/juveniles and males towards their same gender, respectively. The weight of total stomach content was standardised as a function of fish total lengths. Data for the other fish species are presented in S5 Fig . * significant differences ( p < 0.05) between control and vents ( S2 Table ); ** significant differences between males and females/juveniles within controls or vents, respectively. See S1 Data for the underlying data. ns, not significant.
