Average egg production (eggs/mm female prosome length), proportion hatched, and proportion Nauplius IV (N IV) of individual females’ broods in tests pre- and post-acclimation in Exp 12C and Exp 17C.

Average responses of broods in each experiment grouped by target pCO2 treatment, with the standard deviation of (n) measurements (number of females, broods, and broods with hatching for egg production, hatching, and development, respectively).
