Daily curves of gas exchange in leaves from seven-months-old Avicennia schaueriana seedlings grown using a common garden experiment. *Represents rejection of the null hypothesis of the absence of a difference based on an unpaired Student’s t-test, at a significance threshold of 0.05 after Bonferroni correction (n = 10 plants per group). Error bars represent the standard error. Red line: mean values for equatorial samples; blue line: mean values for subtropical samples. (a) Transpiration rate; (b) stomatal conductance; (c) net CO2 assimilation rate.
