Impacts of GA on M. capitata tissue characteristics at the population level.

Summary of the reductions in densities of ova, symbiotic dinoflagellates, mesenterial filaments, and nematocytes seen in Type A and B growth anomalies (GAs), compared to the healthy tissue from histological analysis. Mean values of Type A and Type B severity are shown for all colonies surveyed in this population (n = 1093). The reductions in these parameters were combined with GA severity data (right column, from Burns et al. 2011) to estimate their impacts at the population level (bottom row).
