Macroalgae can inhibit resilience by overgrowing and killing coral colonies, and by producing toxic chemicals which can kill corals or limit coral recruitment by lowering coral fecundity, settlement rates, and post-settlement survival. Herbivores help keep the substrate free from algae so that coral recruits can settle. When herbivores are not present, faster growing macroalgae can overgrow corals. This deprives corals of essential sunlight which can cause declines in coral condition and cover, and reduces the space available for coral settlement. This can result in a phase shift.
