In the lower individual a unilateral cytotoxic reaction at the contact interface has exposed the underlying calcium carbonate corallum (between apposing arrow heads). a significant temperature effect on second-set reaction times.

Allogeneic killing in an incompatible parabiotic graft of the reef-coral, Montipora verrucosa. In the lower individual a unilateral cytotoxic reaction at the contact interface has exposed the underlying calcium carbonate corallum (between apposing arrow heads). a significant temperature effect on second-set reaction times. In both animals at a given temperature, second-set reactions were significantly faster than first-set reactions, except for coral allografts at the warmest (27°C) temperature. Two-way analysis of variance for first-set reaction times in both animals showed significant variation resulting from (i) temperature, (ii) individual graft pairing, genotypic combination, and (iii) interaction between temperature effect and genotypic com- bination. This latter interaction is illustrated by a comparison between the trends in first-set mean reaction times over the three temperatures in coral combinations M1-M13 and M6-M18. Graphic plots of median reaction times (derived from log-normal transforma- tions of the data from the eight different genetic combinations tested for each animal) versus experimental temperature means (Fig. 3) illustrate the general trends in the effect of temperature on allograft reactions. Except for the sponges' strikingly accelerated second-set reactions, which were similar at all three tem- peratures, the grafts generally were rejected faster with increasing temperature. In other words, the sharply heightened immune reactions against repeat sponge grafts were much less affected by temperature than were the reactions involved in the primary response. In the more slowly reacting coral allografts, however, both.
