Box and whisker plots (n = 8) of specific activities of digestive enzymes of fish reared at two temperatures according to PCO₂ levels and feeding levels⁹⁴. Results are given in milli-units per mg of protein (mU mg protein⁻¹) for specific activity and in units per mg of intestine segment (U mg intestine⁻¹) for total activity. Stars denote significant differences (ANOVAs, * < 0.01, ** < 0.001). The whiskers denote the 10^th and 90^th percentiles, the box denotes the 25^th and 75^th percentiles, the median value is shown (horizontal line) as well as outliers (points).
