Carbon dioxide flux in control and heatwave treatment (OTC) plots at the sandy site (a–c) and muddy site (d–f) after 2, 5 and 7 days of heatwave treatment. OTC boxes include data from both 5- and 7-day treatment plots for Days 2 and 5 (n = 20), and 7-day treatment plots only for Day 7 (n = 10). Note the difference in y-axis scales between a–c and d–f. Asterisks indicate significant differences between means at p <*0.05, **0.01, and ***0.001. Boxes show the interquartile range with a black horizontal line showing the median. Whiskers show the non-outlier minimum and maximum.
