Summary of analysis of variance on <i>M. asperrima</i> early life history exposure to elevated <i>p</i>CO₂.

Summary of analysis of variance of the means of % fertilisation and % development to trochophore of M. asperrima embryos in response to 2 and 4 h elevated pCO2 (390, 600, 750, 1000 µatm), and the shell length of D-Veliger, umbonate, pediveliger larvae and spat of M. asperrima after 4 and 6 days in response to exposure to elevated pCO2 (390, 600, 750, 1000 µatm). Significance level is indicated by asterisks, * P<0.05; ** P<0.01; *** P<0.001. Percentage fertilisation and trochophore development was analysed using a single factor ANOVA with “pCO2” as the fixed factor. D-veliger and umbonate shell length was a 3 way analysis where “Time” and “pCO2” were fixed factors and “Container/Tank” was nested in pCO2. Pediveliger and spat shell length were analysed using a 2 factor ANOVA with the “Container/Tank” factor nested in “pCO2”.
