Box plots of growth (number of branches) of aposymbiotic colonies with in situ (a), low (b) and high (c) MA in sulphidic and oxic seawater (Wilcoxon-Mann-Whitney comparisons for each day; *p-value < 0.05, **p-value < 0.01, ***p-value < 0.001); (d) Estimated life span and maximal colony size of the aposymbiotic phenotype under sulphidic (red lines) and oxic (blue lines) conditions with reduced (thin line), in situ (medium line), and enhanced (thick line) MA, are inferred from the parabolas and 95% confidence intervals (dotted lines); (e) Box plots of growth of symbiotic and aposymbiotic colonies grown in the same chamber for seven days (Wilcoxon-Mann-Whitney comparisons for each day; **p-value < 0.01, ***p-value < 0.001); (f) Counted branches and total number of zooids in symbiotic and aposymbiotic colonies of Z. niveum and Z. ignavum, in double logarithmic scale of base 10 with power law fits.
