Pasan Feedback ki pwodwi "espiral nan lanmò byotik" kont detèminasyon an nan yon Reef koray an sante. Entèraksyon biyotik yo pwodwi remak pozitif oswa negatif ki kondwi yon resif nan direksyon swa yon eta malsen nan dominasyon alg, ak dekline koray, pwason, ak konpleksite estriktirèl (bò gòch nan imaj), oswa nan direksyon yon eta fleksib sante nan dominasyon koray, ak kèk alg kèk. , anpil pwason, ak yon gwo estrikti konpleksite ki te fòme pa kwasans koray (bò dwat nan imaj). To erbivwa se entèraksyon kritik pou detèmine si fidbak la pozitif oswa negatif. Sous: Mumby ak Steneck 2008, Hay ak Rasher 2010.

Feedback loops that produce the “biotic death spiral” versus the resilience of a healthy coral reef. The biotic interactions producing positive or negative feedbacks that drive a reef toward either an unhealthy state of seaweed dominance, with declining corals, fishes, and structural complexity (left side of image), or toward a resilient healthy state of coral dominance, with few seaweeds, many fishes, and a high structural complexity formed by coral growth (right side of image). Rate of herbivory is the critical interaction determining whether the feedback is positive or negative. Source: Mumby and Steneck 2008, Hay and Rasher 2010.
