| Summary: | Mean (+ SE) relative abundance of mature males of the common, blue-eyed, and Yaldwin’s triplefins, respectively (a), and size–abundance distribution of mature males of the common triplefin (b), at control and CO 2 vent sites. The abundance of mature males was quantified in situ based on gender-specific (nuptial) body colouration and calculated as the number of mature males relative to total number of males, females, and juveniles per transect; this was not possible for the crested blenny which lacks secondary sex characteristics. Data are from years 2017 to 2019 ( S4 Table ), with circles representing replicate transects (jittered on x -axis where values overlap; * significant difference ( p < 0.05) between treatments ( S1 Table ). See S1 Data for the underlying data.
