Hosting yon plis chalè-toleran Symbiodinium yo pral akonpaye pa konpansasyon nan fizyoloji nan koray la. Plis zooxanthellae ki reziste chalè ka vini ak depans ekolojik, tankou kwasans redwi ak redwi kapasite repwodiksyon, e kon sa pi ba rekiperasyon apre domaj. Yon etid ki fèt nan zile yo nan rejyon Keppel Gran Reyal Baryè a te envestige kwasans zo. Anba kondisyon kontwole, Acropora millepora koray ak klé D symbionts grandi 29% pi dousman pase sa ki gen klan C2 symbionts. Nan jaden an, koloni Clade D te grandi 38% pi dousman pase klade C2 koloni. Rezilta sa yo demontre gwosè echanj konpwomi yo ki ka gen eksperyans pa espès sa a pandan y ap aklimate a pi cho kondisyon pa chanje nan plis tèmik toleran klowòf zooxanthellae. ref

Hosting a more heat-tolerant Symbiodinium will be accompanied by tradeoffs in the physiology of the coral. More heat-resistant zooxanthellae may come with ecological costs, such as reduced growth and reduced reproductive ability, and hence lower recovery following damage. A study conducted in the islands in the Keppel region of the Great Barrier Reef investigated skeletal growth. Under controlled conditions, Acropora millepora corals with clade D symbionts grow 29% slower than those with clade C2 symbionts. In the field, clade D colonies grew 38% slower than clade C2 colonies. These results demonstrate the magnitude of trade-offs likely to be experienced by this species as they acclimatize to warmer conditions by changing to more thermally tolerant clade D zooxanthellae. ref
