| Summary: | ( a ) Mean otolith increment width (proxy for somatic growth in last few weeks before capture) for male (filled markers) and female (clear markers) common triplefin at control (solid line) and vent (dotted line) sites with fitted regression lines and R 2 values. ( b ) Mean (+ SE) in situ size–abundance distribution of combined females/juveniles of the common triplefin at control and vent sites. ( c ) Mean (+ SE) sex ratios of the 4 species at controls and vents. Circles represent replicate transects (jittered on x -axis where values overlap; jittering on y -axis for sex ratio common triplefin at vents: top circles, all 100%). Sex ratio was calculated as the number of males relative to total number of males + females; gender was determined in the laboratory and included the crested blenny. See S1 Table for statistical results and S1 Data for the underlying data. ns, not significant. (PDF)
