Cuticle mineralization.
Box plots of the mineralization content (presented as weight percent calcium [Ca] and weight percent magnesium [Mg]; box boundaries = the 25th and 75th quartiles, error bars = 1.5 times the interquartile distance, center line = median, diamond = mean) in the cuticle for (a,c,e) the carapace and (b,d,f) merus from the three- and six-month exposure periods (N = 105). (a,b) Ca, (c,d) Mg, and (e,f) the ratio of Ca:Mg. Mg in the merus from the reduced pH treatment, in particular, is significantly different from the other treatments. Black dots represent outliers from the box plots that were included in the analyses.
